    DESCRIPTION

    Biocidal composition for the control of pests and invasive species, coating products and their use.
     5
    SECTOR OF THE TECHNIQUE

    The present invention falls within the Chemical sector, specifically in the area of the manufacture of insecticides and repellents of invasive species and pests, at the environmental, agricultural, livestock and domestic level, so it is applicable in the field of health. Public, Agriculture and Animal or Plant Health.

    STATE OF THE TECHNIQUE

    Invasive species are those animals, plants or others organisms transported 15 e introduced, almost always by the human being, in places outside their natural distribution area and that have been established and dispersed in the new region, where they are harmful. This is the reason why these species are treated in a particular way. Thus, the Official State Gazette of December 12, 2011, SEC. I, page 132711 regulates the Spanish Catalog of Invasive Exotic Species and the List of Exotic Species 20 with Invasive Potential in Spain.

    The damage caused by these species affects various habitats but especially sensitive are degraded or altered ecosystems such as agriculture or urban, but also others such as marine or river ecosystems. At the ecological level, the loss of native diversity and the degradation of invaded habitats stands out. Economically, direct effects on agricultural activities and public health are important, including the transmission of diseases to man and animals. Invasive species of urban and domestic environments are especially problematic as they directly affect billions of people. 30

    Coating products with insecticidal action have already been marketed for a long time, such as the compositions disclosed in patent application EP0235584 (A1). However, these compositions have several important drawbacks for their common use: 1) they contain disused active ingredients, which are not new generation; 2) some of these active substances are currently prohibited in the European Union (eg organochlorines) due to their toxicity; and active ingredients are used, such as traditional pyrethroids, which do not produce a residual character and have little effectiveness over time. These problems have recently been addressed and corrected to some extent, with new formulations having been subsequently designed, such as those described in Spanish patent no. 2127120 for arthropod control. These non-toxic and residual products act as inhibitors of chitin synthesis, one of the main components of the arthropod exoskeleton. The formulation of this type of compositions basically comprises resin, pigment, fillers and active ingredients that are microencapsulated with the resin polymer itself in the manufacturing process. Likewise, Mexican patent application MX / a / 2008/006733 describes compositions similar to the previous ones, but in which alternative insecticides to organophosphates and carbamates are used because the use of the former has been restricted and regulated during the last years in a growing number of countries.
     fifty
    Indeed, at present the controls on the use of phytosanitary products in the European Union are very demanding, both by the European Food Safety Agency and by the competent authorities of each State. It is necessary to control the use of phytosanitary products and reduce their application, and this is being done. The industry is still adapting to the latest
    active substance restrictions. The issue is of magnitude. The current proposal is radical and gives little scope to the farmer and the industry for the search for new alternative and profitable products. A proposal for a regulation for the marketing of phytosanitary products is also under discussion. It further restricts authorized active ingredients 5

    European directive 91/414 / EEC on the marketing of plant protection products establishes uniform standards for evaluation, authorization, marketing and control within the European Union of plant protection products and the active substances they contain. Only phytosanitary products whose active substances 10 are included in the list in Annex I of the Directive and which, if used under normal conditions, do not present risks to human or animal health or to the environment are not authorized.

    The current trend is to a significant reduction of the active materials - and with that of the formulated - authorized, this situation is leading to serious pest problems in 15 numerous crops, affecting mainly the countries of the Mediterranean basin that, due to the Goodness of their climate has an agriculture very sensitive to the appearance of pests. A peculiarity that occurs with less intensity in central and northern Europe.

    The disappearance of formulated so far effective against pests and the absence of 20 alternatives, at least equally effective forces the search for new alternatives within existing and authorized products.

    Thus, the present invention emerges within this current context as a new tool for pest control that is innovative not for the active ingredients present therein but for its special formulation as a biocidal coating. This is achieved by modifying the nature and / or proportion of the fillers, pigments and polymers included in the formulation. Ultimately, the invention relates to a new improved and expanded formula for the control of all types of organisms, particularly invasive species belonging to different living beings of the Animal Kingdom, Fungi and Protists, mainly 30 (arthropods, molluscs, nematodes, birds, algae, fungi, among others). This control is carried out thanks to a series of active substances that are microencapsulated with a binder in a polymeric and mineral envelope, such as those already described above but which has special use of fillers and additives of a different nature than the previous ones that get improve various aspects related to the release of biocidal assets, the application technique and the final result of the application. These active substances are biocides that can belong to the group of insecticides, acaricides, molluscicides, algaecides, fungicides and others, and be of a synthetic nature or of natural origin (plant, animal or mineral). The control action on invasive species can be carried out through a preventive or curative mechanism of action because the active ingredients can have a biocidal and / or repellent effect.

    DESCRIPTION OF THE INVENTION

    Brief Description of the Invention

    The present invention relates to a biocidal composition for the control of organisms that act as invasive species of natural ecosystems and intervened by human beings (agricultural, domestic ...), applicable in the fields of public health, animal or plant health, agriculture and others. Said biocidal action may be insecticide, acaricide, molluscicide, algicide, fungicide, arthropod repellent, inhibitor of chitin synthesis and / or regulator of juvenile insect hormone, depending on the components selected.

    Thus, the composition object of protection comprises:
    - Between 0.1% and 75% by weight of the total weight of the composition, including both limits, of at least one active agent, which is a biocide selected from the group consisting of: synthesis biocide of organic or inorganic origin, biocide natural of vegetable origin and natural biocide of mineral origin.
    - Between 10% and 70% by weight of the total weight of the composition, including both limits, of 5 water;
    - Between 1% and 50% by weight of the total weight of the composition, including both limits, of at least one polymeric and / or mineral nature binder, which envelops the active ingredients in the form of a microcapsule. Y
    - between 0.01% and 40% by weight of the total weight of the composition, including both limits, 10 loads.

    The described composition provides a new methodology, for the control of invasive species, in which, by a single application, high efficiency is achieved on a wide diversity of invading organisms in the fields of agriculture, environmental and veterinary, among the that stand out: nematodes, mollusks, arthropods (insects, arachnids and crustaceans), algae and even birds. Being more specific, the compositions act particularly well with the following species:

    - Nematodes: Bursaphelenchus xylophilus (pine nematode) 20
    - Molluscs: Achatina fúlica (giant African snail), Corbicula fluminea (clam of Asian river), Dreissena polymorpha (mussel zebra), Pomacea spp. (apple snail), Potamopyrgus antipodarum (silt snail)
    - Insects: Aedes albopictus (tiger mosquito), Lasius neglectus (invasive ant), Paysandisia bunker (Palm-boring caterpillar), Rhynchophorus ferrugineus 25 (Palm weevil), Vespa velutina (Asian wasp), Phlebotomus spp. (transmitters of leishmania in humans and canids and Schmallenberg virus), Culicoides (transmitters of bluetongue disease and Schmallenberg virus) and Culex spp. (West Nile Virus transmitters).
    - Crustaceans: Procambarus clarkii (American river crab). 30
    - Birds: Myiopsitta monachus (Argentine parrot), Psittacula krameri (Kramer parrot), Streptopelia roseogrisea (turtledove rosigris).
    - Algae: Caulerpa taxifolia, Caulerpa racemosa, Sargassum muticum.
    - Arachnids: mites, ticks, spiders and scorpions.
     35
    Among invading organisms in domestic, livestock or agricultural environments, the compositions act effectively as a control agent preferably for: cockroaches (Periplaneta americana); bed bugs (Cimex lectularius); mosquitoes (Culex quisquesfasciatus); ants (Argentine ant –Linepithema humile-); dust mites (Dermatophagoides farinae); and birds (Turkish turtledove -Streptopelia deaocto-, pigeon -Columba livia-, laughing gull -40 Larus ridibundus-).

    Basically, the formulation acts primarily by contact, but also by inhalation. The described biocidal composition is based on the encapsulation of the active ingredients (biocides, which are insecticides, growth regulators, etc.) in a binder of polymeric nature, with mineral coating, thereby increasing its scope of use. The structure of the microcapsules that constitute the composition is an active nucleus and a framework, wall or matrix that surrounds the first. The objective of the composition is to achieve high efficiencies for a relatively long period of time, thus avoiding unnecessary repetitions of the treatment and, thus, less contribution of pesticides to the environment, in addition to labor savings.

    It should be noted the great persistence of the composition, which is due to the gradual release of the active ingredients due to the existence of the microcapsule. That is, the formulation of the
    Binding microcapsule of polymeric nature, with mineral coating, allows the progressive and gradual release of the microencapsulated active ingredients, over time. This release is directly proportional to room temperature; Thus, when it is hotter, there are more insects and the greater the release of active ingredients from the composition, while in the colder months the release of insecticides to the environment is much lower, coinciding with the smaller population of insects in crops. .

    Prior to the application of these biocidal compositions as coatings / coatings, the particles of the active materials are dispersed in the water. After application, the water evaporates and the particles approach until they join each other. With the passage of time and the action of external agents, the particles closest to the surface are released into the environment. An increasingly stable film is formed in which assets are protected and are released more and more slowly. Thus a stable film is formed with regulated diffusion of the active agents. Since these assets are trapped within the polymer structure, and that their release is slow and gradual, the amount of insecticides in the environment is very low, which considerably decreases the already low toxicity of said ingredients. . All this gives the composition some properties hardly observed in other conventional pesticides, such as immediate efficacy, prolonged efficacy, very low toxicity and easy application.
     twenty
    The process of obtaining the composition is complex, since the active substances are introduced into the matrix or wall system of mineral polymeric nature, achieving a gradual release of the active agents, inserted according to the specific needs of application of the substrate in the that the microcapsules are deposited and, above all, of the invasive species that is intended to be controlled. The microcapsule formation is a chemical process between the aqueous mineral polymer and the active agents, all of them together or separately in the polymer matrix in the encapsulation. Said process can be carried out by interfacial polymerization. This method consists in the polymerization of at least one monomer at the interface of two immiscible substances, giving rise to a membrane that constitutes the wall of the microcapsule. In this process an aqueous solution of at least one water soluble reactant is dispersed in an organic phase, giving rise to an emulsion. The formation of a polymeric membrane on the surface of the water droplets of the emulsion results in the microcapsules.

    The composition is easy to apply, durable, rain resistant and effective. Also the mineral polymeric shell contributes to the durability and effectiveness of the active substance, protecting the active substance and facilitating its diffusion.

    Detailed description of the invention
     40
    As mentioned, the biocidal active agents are selected from the group consisting of biocidal synthesis of organic or inorganic origin, natural biocide of plant origin and natural biocide of mineral origin. That is, they can be very diverse in nature. Preferably, the biocides of synthesis of organic or inorganic origin for use in public health, animal health or plant health may be selected within group 45 consisting of:

    - organophosphorus and / or carbamates, whose mode of action is based on inhibiting the action of the enzyme acetylcholinesterase that is responsible for nerve transmission;
    - pyrethroids, which also affect the insect's nervous system but act as 50 dissociators of the axon membrane, keeping the sodium channels of said membrane open;
    - neonicotinoids, which act on the central nervous system of insects, causing an irreversible blockade of nicotinergic postsynaptic acetylcholine receptors;
    - phenylpyrazoles, which block the chlorine channels regulated by -aminobutyric acid (GABA) in insect neurons;
    - chitin synthesis inhibitors, which prevent the correct formation of the insect cuticle; Y
    - insects juvenile hormone analogues, which prevent the correct development of 5 adults and affect fertility.
    - synthetic molluscicide biocides, which are preferably selected from the group consisting of: niclosamide, fentilhydroxide and metaldehyde;
    - synthetic nematicidal biocides, which are preferably selected from the group consisting of: Fenamiphos, Oxamyl, Carbofuran, Terbufos, Etoprofos and Cadusafos; 10 and
    - any combination thereof.

    All these groups are insecticides that act by contact, ingestion and inhalation and do so on the different stages of development of insects and arachnids, although the egg phase 15 is especially resistant to its action.

    Preferably, the organophosphorus biocides are selected from the group consisting of: Diazinon, chlorpyrifos, methylchlorpyrifos, malathion, tricolfon, dimethoate, dichlorvos, methamidophos, acephate, parathion, pheitrotion, fenthion, methyl asynphos. On the other hand, carbamates are more preferably of the type: metomyl, aldicarb, oxamyl, thiodicarb, methiocarb, propoxur, bendiocarb, carbosulfan, phenoxycarb, pyrimicarb, indoxacarb, alanicarb and furatiocarb. Pyrethroids are preferably selected from the group consisting of: Aletrin, d-aletrin, alpha-permethrin, cypermethrin, permethrin, tetramethrin, bioalethrin, fenvalerate, biphentrine, kyphlutrin, deltamethrin (which is one of the preferred insecticides in this invention, 25 for its effects and its speed of action against the invasive species), praletrin, acenatrin, imiprotrine, lambda-cihalotrine, gamma-cihalotrine and etofenprox. Neonicotinoids are preferably selected from the group consisting of: imidacloprid, acetamiprid, thiamethoxam, nitenpyram, clothianidine, dinotefuran and thiacloprid. Phenylpyrazoles are preferably selected from fipronil and endosulfan. The chitin synthesis inhibitors are preferably selected from the group consisting of: flufenoxuron, hexithiazox, diflubenzuron, hexaflumuron and triflumuron. These chitin synthesis inhibitors are framed within the so-called growth regulating insecticides (IGRs) and have the following mode of action: the insects are covered by a rigid exoskeleton, the tegument, which gives them protection and prevents loss of water, which allows its survival. Insects, in order to develop and due to the stiffness of the aforementioned tegument, must grow discontinuously. To do this, they periodically detach themselves from the tegument and create a new one of larger size, this process is known as "molt". The application of chitin synthesis inhibitors used in the formulation results in a process capable of inhibiting the mechanism of production of chitin, the main component of the tegument. By preventing its production, the formation of a new tegument is blocked and as a consequence the process of “molting” does not take place, so that its development and, therefore, its existence is unfeasible. The activity of the product affects all states of sensitive insects albeit differently. It affects the eggs of some species when they are deposited on plant parts of the treated plants or when they are treated once they are deposited. Eggs may develop, but the larvae coming from them or are unable to emerge or die soon after. It affects the larval states preventing molting, which leads to the appearance of symptoms such as: double head capsule, thoracic bulge, and displaced or deformed jaws. As a consequence of the impossibility of moving, the larvae die when they cannot evolve to 50 later states. And, due to the aforementioned deformations, they cannot feed what makes their survival impossible. Larvae exposed to sublettal doses of the product may "pupate" but either do not produce viable adults or give rise to adults who lay fewer eggs than normal. It affects adults by reducing their fertility. As for the hormone analogues
    Juvenile, these are preferably selected from the group consisting of: Pyriproxyfen, Phenoxycarb, Hydroprene and Methoprene.

    Natural biocides of plant origin can be selected from the group consisting of: citronella oil, lavandin oil, garlic extract, eucalyptus oils, 5 thyme oils, basil and others extracted from plants with biocidal and / or repellent properties such as they are for example: saponin (quinoa), Allium sativum, Digitalis purpurea, Eucalyptus Globesus, Euphorbia helioscopy, Foeniculum vulgare, Laurus nobilis, Rosmarinus officinalis, Blonde pilgrim and Ruta graveolans.
     10
    Natural biocides of mineral origin are preferably selected from the group consisting of iron sulfate, copper sulfate, quaternary ammonium salts, sodium carbonated peroxyhydrate and silver chloride.

    As for the binders of polymeric nature, which form the polymeric wall or matrix and envelop the active agents, they are preferably selected from:

    - water-based or organic solvent-based compounds, such as the following:
    - compounds based on vinyl acetate, modified or not with acrylic or methacrylic resins; twenty
    - compounds based on acrylic or methacrylic resins, modified or not with styrene;
    - compounds based on vinyl chloride dispersions, VeoVa type resins, acryl nitrile type resins, alkyl resins, epoxy resins, styrene-butadiene resins or polyurethane resins;
    - cellulose derived binders such as cellulose acetobutyrate or nitrocellulose; 25
    - alkyd, phenolic resins, urea and melanin formaldehyde resins, epoxy resins, chlorinated rubber, polyvinyl chloride, acrylic resins, polyurethane resins or natural gums;
    or
    - binders with FDA authorization (food use), such as those selected within group 30 consisting of:
    - polyvinylpyrrolidone or carbohydrate-based compounds (starches, alginates, carrageenans, pectins, cellulose derivatives, chitosan or gums);
    - animal proteins (casein, whey protein isolate, collagen, egg albumin, fish protein, keratin); 35
    - proteins of plant origin such as zein and gluten; Y
    - lipids (waxes).

    The biocidal composition comprises loads in a percentage comprised between 0.01% and 40% by weight of the total weight. Preferably, said fillers are mineral fillers, and more preferably they are still selected from the group consisting of calcium carbonate, talc, quartz, dolomite, kaolin, silicates, titanium dioxide, sodium hexametaphosphate and / or sodium nitrite.

    EXAMPLES OF THE INVENTION

    Several examples of the biocidal composition, its application in coatings and its biocidal action, its preparation and its use in the manufacture of textile garments, are illustrative and non-limiting of the invention.

    Example 1: Preparation of the microencapsulated biocidal composition, in the form of a coating.
     fifteen
    The formulation used to make the coating composition is made based on a chain of VeoVa vinyl polymers in which the active ingredients (chlorpyrifos) have been microencapsulated in what is called the Insecticide Polymeric Microcapsule (MPI).
     twenty
    Example 2: Properties of a coating that incorporates as an ingredient the composition described in Example 1.

    It should be noted the great persistence of this formulation, which is due to the gradual release of the active ingredients. Since these assets are trapped in calcium carbonate, and their release is slow and gradual, the amount of insecticides in the environment is very low, which considerably decreases the already low toxicity. In addition, the formulation does not contain organic solvents, water being the only solvent used; another key factor in its low toxicity, since the toxic effects that are derived from them are eliminated. All this gives it properties that are hardly observed in other conventional pesticides, such as immediate efficacy, prolonged efficacy, very low toxicity and easy application.

    The vinyl-aqueous polymer based formulation allowed the gradual release of the active ingredients over time. It was found that this release was directly proportional to the ambient temperature, so when it was warmer there were more insects and the greater the release of active ingredients, while in the colder months the release of insecticides to the environment was much lower , coinciding with the smaller population of insects in the crops.
     40
    Example 3: Laboratory tests using the composition described in Example 1, against the red weevil (Rhynchophorus ferrugineus).

    The red weevil (Rhynchophorus ferrugineus) is the most worrisome pest currently in the palm trees of Spain. Originally from the tropical areas of Southeast Asia and Polynesia, this curculionide is increasing its range in Spain has been detected in date palm (Phoenix dactylifera) and in Canary Island palm (Phoenix canariensis), mainly in male feet of this palm. Rhynchophorus ferrugineus lives and feeds inside palm trees, a condition that makes it difficult to detect its presence with a simple visual inspection. The interior of the palm gives protection and strong adaptability to different geographical areas with different climatic conditions, which influence the periods of development of the phases of its biological cycle. Due to its biology and its gregarious character, a single infested palm tree can be the beginning of a great infection, since in its interior up to a thousand individuals can develop, overlapping different generations and coexisting
    all stages of its cycle in the same palm. The severely affected or dead palms must be plucked and burned to prevent the exit of adults and their dispersion. Being its native tropical climate, it has been successfully established in desert areas with extreme temperatures, in Mediterranean areas and in temperate areas such as the Canary Islands. In addition, it is worth mentioning that it has already been detected in the Americas. 5

    An assay was carried out to determine the efficacy of the white composition with insecticidal properties by the active agent chlorpyrifos, applied on adults of Rhynchophorus ferrugineus. To do this, a palm tree block was cut, applied with a brush, the product was allowed to dry and 10 adults were placed in a closed plastic container with 10 holes for ventilation (see Fig. 1).

    It was found that adults died at approximately 24 hours. Although this effect was completely satisfactory, this excessively long time was considered (since the adult at that time could have moved to other untreated areas) and it was proposed to change the insecticide, using deltamethrin.

    Laboratory tests indicated that at two hours, adults were affected, on their backs, moving their legs, but without mobility. At 24 hours they were all dead. The white control formulation, without insecticide, had no effect on the pest (see Fig. 1). twenty

    Product contact time

    In the laboratory, 10 adults were placed in a container with the palm block, treated by separating them at 13 minutes and placed in another container with an untreated palm block; the same test was repeated, taking them 30 minutes and 60 minutes. 60 minutes of contact were enough for adults to die before 24 hours. Thus, it is possible to think that the product must be in the place where the adult takes refuge since there he can spend that time in contact with him. The test carried out has shown preventive efficiencies of more than 6 months, with which with a single annual application a palm tree could be protected during the 30 period of activity of the weevil.

    Example 4: Field trials of a formulation derived from that described in Example 1, against the red weevil (Rhynchophorus ferrugineus).
     35
    The formulation used based on the insecticidal composition of Example 1 was also made by a chain of vinyl polymers VeoVa, but in this case the active ingredient that has been microencapsulated is deltamethrin instead of chlorpyrifos.

    Field trials were initiated in three plots and among the products tested was the white formula with deltamethrin, applied on the walloon (upper part of the stipe from which the lower or dried leaves are pruned), of previously pruned palm trees. The plants (Canary palms) were placed in pots or containers. The objective was to prevent the establishment or prevent the emergence of larvae of the red weevil.

    There were 8 Canarian palm plants, half a meter in diameter, approximately. At the time of placing the palm trees on the test plot, the basal part of the container was cut and partially buried in the ground. In turn, a drip irrigation system was installed for maintenance. The elementary plot was formed by 4 palm trees, at a distance of at least 2 meters.

    Two theses are compared: brushed and treated palms with the white formulation with deltamethrin versus untreated brushed palms. The separation between the two is at least 10 meters. The base of the leaves was treated with the formula, introduced in a backpack sprayer, diluted in 40% water without a nozzle and the stipe was applied by brush diluting the product to 10% -15% water. 5

    A pruned palm tree attracted nearby adults. With the formulation it was tried to avoid that the adult females could effect the putting in the palm tree. The following Table 1 summarizes the sawdust secretions and the condition of the palm trees.

    If the dates, noted in the first row of Table 1, are observed on day 29-08, in a quick visual inspection, a larva of last 15 stage and 15 buds with nymphs were removed from the rotten bud of the control palm 4. newly formed adults, with more individuals left inside. In September, the second palm of the witness plot died and in October the third. At the beginning of January of the following year, the fourth witness palm is very affected. On the contrary, the four palm trees treated with the formulated with deltamethrin, remain healthy in the plot. The field results showed that the formulated with 20 deltamethrin kept the palm trees 9 months protected from infestation by red weevil.

    4.2 Formulated brown
    As the white color is too striking for concrete practical application, a brown formula was prepared that maintained the characteristics of the previous one and that mimicked the color of the palm tree trunk. This was done in a similar way to the previous one. First its validity was tested in the laboratory. Thus, its effectiveness was evaluated by placing 10 adults in a container with a palm tree treated with this formula. It was found that between two and three hours adults died in a similar way as they did with the white product.
     30
    In the field, 6 canary palm trees were used in pots, brushed, three painted with the brown spray formulation. Each one was covered with mosquito netting and placed in its
    Inside 20 females and 10 males. Then the meshes were closed. 8 days later the dead individuals were counted and 10 females and 5 more males were introduced in each of them, then the meshes were closed.

    It was observed that in the palms treated with the brown formula with deltamethrin, a mortality of more than two thirds of the introduced adults was observed. After a month and a half, some sawdust secretion was seen. In two of the three palm trees of the first witness, after two months, several galleries were appreciated.

    A witness palm died 4 months after the first introduction. The second, seven months after the first introduction. The three palm trees of the second witness died two months after the introduction. Palms treated with the brown formula remain alive (except one) within twelve months of the first introduction of adults. However, this dead palm showed no traces of weevil.
     fifteen
    In conclusion, with the brown formula, the efficacy was verified 12 months after treatment.

    Persistence of the action of the insecticide in the formulation

    For the laboratory test, each of the treated tacos, at the end of each test, 20 were left on a 24-hour outdoor terrace and exposed to the sun for several hours a day. The persistence test was repeated monthly. The last test was performed six months after treating the taco with the white formula and deltamethrin. The taco is dry, but the product remains. The result was that within two hours of being in contact with the treated piece, the adults were all affected (face up and moving their legs). In less than 25 24 hours they died. The same happened with the piece of palm tree treated with the brown formula and deltamethrin four months after the treatment.

    conclusion
     30
    Dramatically highlights the potentiation of the insecticidal effect of the formulation and especially its persistence and uniformity. The product tested, with deltamethrin, can be effective in protecting pruned palm trees, counteracting the effect called freshly pruned tender tissues exert on red weevil adults.

    Example 5: Field application tests of the composition described in Example 1, against aphids in citrus and horticultural.

    Aphids are small insects that group together forming leaf colonies and young shoots. Aphids are typical opportunistic insects that live in temperate zones. The 40 damages that they produce in citrus fruits derive from their feeding by absorption of sap, deformations by injection of toxins, transmission of virosis and production of molasses. The most important species in citrus fruits are Aphis frangulae gossypii, Aphis citricola, Toxoptera aurantii and Myzus persicae.
     Four. Five
    Citrus Virosis

    The most serious virosis in the Mediterranean area is the Sadness of citrus. It is a disease caused by a virus that affects orange, mandarin and grapefruit grafted on bitter orange. It basically spreads through the aphid bites. Kill 50 the tree in a short time (collapse in 2 or 3 weeks if the virus is more virulent) or slower decay (months) with scarce productions. This if the virus is more virulent.
    Virosis in greenhouse horticultural

    Virosis in protected crops have come to produce losses of many billions of pesetas, especially in horticultural. In tomatoes the virus of the tanned spots of the tomato or spotted (TSWV), is of the most important, it is transmitted by means of trips. These 5 insects in addition to causing wounds in the plants with the punctures that they produce when feeding, also damage the plant in the laying of eggs, since these are placed by the insect under the epidermis of the vegetable.

    A control method was designed to prevent virosis in a preventive manner, preventing the vector from making a bite - trial or feeding - on the plant, by using the biocidal composition obtained in Example 1.

    It has been proven that the placement of barriers (fabrics, meshes) treated with the product in question without contact with the vegetable in open field crops has reduced the arrival of 15 aphids, thereby the number of bites in the plants and, therefore, , the risk of getting virosis.

    Example 6: Field application tests of the formulation described in Example 1, against citrus ants. twenty

    In citrus crops, ants can be considered as a direct pest, since they feed on young shoots and can cause damage to structures - irrigation pipes - and even inconvenience to farmers.
     25
    But, without a doubt, the biggest problem of these species is that they act as indirect pests because they make it very difficult in natural control by parasites and predators of aphid populations, who find protection in these hymenoptera "in return" for molasses. In citrus crops we can find a wide variety of ant species among which we will highlight Lasius niger, Lasius grandis, Linepithema humile, 30 Tetramorium caespitum.

    The biocidal composition of Example 1 has been shown as an effective orange ants controller by applying in a 15cm band. around the trunk, which is enough to prevent ants from climbing the trunk for 7 months. This means that a single annual application of the formulation is sufficient for the control of ants (Annex IV).

    Example 7: Field application tests of a formulation with a biocidal composition according to the present invention, against the apple snail (Pomacea caniculata). 40

    It is a snail from an extensive area of South America. It is a very voracious herbivorous species, so that it affects vegetables and aquatic algae by ingestion. At present there is no alternative cost-effective method for the treatment of areas outside the fields. The objective was to obtain a product with 45 molluscicide effects that was cost-effective, lasting over time and that would prevent Pomacea females from making their lay. The microencapsulation of the molluscicides was carried out in an active matrix of CO3Ca and resin, incorporating it into a coating that promotes a gradual and slow release of the active ingredients, increasing their persistence, being harmless to humans and other species that share habitat. fifty

    The process of application of the molluscicide formulation was similar to the application of any phytosanitary with the proviso that its persistence is much greater, of several months. 7 different formulations were used in accordance with the present invention:
    SP1. INESFLY POMA SIN: This is a control formulation composed of a composition with a low percentage of loads. It is used in the test as a control to rule out mortalities of snails other than those formulated.
    SP2. INESFLY POMA + 5% Saponin: It is a formulation that contains 5% saponin molluscicide, included by the microencapsulation process in a formulation with a low percentage of loads.
    · SP3 INESFLY POMA + 5% Iron Sulfate: It is a formulation that contains 5% iron sulfate molluscicide, included by the microencapsulation process in a formulation with a low percentage of loads.
    · SP4 INESFLY POMA + 0.01% pyriproxyfen: It is a formulation containing as active ingredient the IGR pyriproxyfen 0.01%, included by the microencapsulation process in a formulation with a low percentage of loads.
    SP5 INESFLY POMA + 5% niclosamide: It is a formulation that contains 5% niclosamide molluscicide, included through the microencapsulation process in a formulation in a formulation with a low percentage of fillers. fifteen
    · SP6 INESFLY POMA + 2.5% saponin + 2.5% iron sulfate + 0.01% pyriproxyfen: It is a composition that contains a combination of two molluscicides (2.5% saponin and 2.5% iron sulfate %) and an IGR (pyriproxyfen 0.01%) included by the microencapsulation process in a formulation with a low percentage of loads.
    SP7 INESFLY POMA + 2.5% saponin + 2.5% iron sulfate + 2.5% niclosamide: It is a composition that contains a combination of three molluscicides (2.5% saponin, 2% iron sulfate, 5% and 2.5% niclosamide) included by the microencapsulation process in a formulation with a low percentage of fillers.

    All of them had a flavoring, lemon scent. 25

    Different sheets painted directly with the compositions were enabled. The sheets were treated, one by one and waited 3 hours to perform the second application. The same was done with the sheets first treated with bridge product. In order to observe the behavior of the snails in 60 x 40 cm polypropylene buckets for 8 days, 4 x 100 cm bands were cut and glued to the top of the bucket, covering the entire perimeter. A surface with thermal insulation was also prepared to keep the cuvettes warm.

    Behavior of formulations with biocidal action 35

    The behavior of the formulations is very varied; None need to be diluted, they are too liquid and I appreciate a strong lemon smell in almost all.
    - Behavior on sheet without primer:
    · SP1: dries well, is too diluted, smells like lemon, is transparent. 40
    · SP2: DOES NOT dry, perhaps the most diluted of all, it smells like lemon although less than SP1, it is brown with light milk.
    · SP3: The first application does not dry well, in the following passes it has the best adhesion is also too diluted, it has small sheets (impurities) on the surface that I drag with the roller when applying, it smells like lemon, it is 45 cream-reddish color.
    · SP4: same characteristics as SP1.
    · SP5: Does not dry well, is too diluted, smells like lemon, is yellow.
    · SP6: dry well, is too diluted, smells like lemon, is dark brown.
    · SP7: it dries well, it is too thick, texture similar to a thick mucus, it smells very rare but does not bother, it is very dark brown.

    Each product behaves in a different way, the drying time from least to greatest:
    SP1 = SP4 <SP7 <SP3 <SP6 <SP5 <SP2

    The formulations have good flexibility, do not wash easily. All these qualities are enhanced if a primer is applied on the sheet.

    Assay Methodology 5

    - Proceed to the selection of 4 healthy females of the largest possible size for each bucket, total 28 females.
    - Assembly of the acclimatization system, consisting of a first layer of thermo-mat type insulating material, an electric blanket of 120 W of 160 x 140 cm power and 10 a second layer of insulating material of the same characteristics to the first to avoid if possible the loss of heat.
    - Bonding of the treated sheets without primer on the top of the sides of the tray.
    - Material used: 15
    o Polypropylene buckets of 60x40 cm.
    o Sheets of transparent self-adhesive painted film, without primer.
    o Electric blanket 160x140 cm, 120 W of power.
    or 2 thermo-mat mats of 70x200 cm.
     twenty
    Process

    The treated sheets were glued to the sides of the perimeter of the cuvettes on their inner and upper face. The cuvettes were placed on the blanket and this on the mat to avoid heat loss. The cuvettes were filled with 8 liters of water, leaving a height of 15mm between the water and the glued sheets, ensuring that the water did not touch the product to avoid any drift inside the container. 4 healthy females of medium-large size were placed in the center of the cuvette to observe if they moved inside the cuvette, after a few minutes it was found that all the individuals remained active, otherwise those who were not were changed . Another cuvette was placed upside down in a lid mode and covered with the electric blanket and the other mat on top, left 24 hours with the thermostat in position # 2. After 24 hours, the water temperature, the presence of dead animals were monitored and their relative position in the bucket was noted.

    Results 35

    Three series of experiments were carried out, the first series corresponded to an untreated cuvette under the same temperature conditions, 1 setting was observed after 24h. The second series corresponded to cuvettes SP2, SP5 and SP6 observing the following, (day +1):
    - D + 1: there are no put in any cuvette, moisture condensation has produced a drift of a certain amount of product on the water, with the following result:
    o SP2: 4 dead individuals (100%)
    o SP5: they are inactive, with the opercle closed.
    o SP6: same as SP5
    - D + 2: SP5 and SP6 same as the previous day. Four. Five
    - D + 3: SP5 snails are removed from the water, they smell very bad, they are dead. SP6 seems to resist, they are closed.
    - D + 4: SP6 dead, end of trial.

    The third series corresponded to cuvettes SP3, SP4 and SP7 observing the following, (day +1): 50
    - D + 1: there are no put in any bucket, moisture condensation has caused the drift of a certain amount of product on the water, with the following result:
    o SP4: the 4 individuals still active move through the bottom of the bucket, it seems that it does not affect them.
    or SP3: 2 are active the other 2 are closed.
    or SP7: 100% dead.
    - D + 2: SP4 and SP3 the same as the previous day.
    - D + 3: SP4 the same as the previous day, in SP3 the larger female is floating dead. 5
    - D + 4: SP4 assets.
    - D + 5: end of the test, SP4 are still active.

    Conclusions
     10
    The snails did not approach the treated sheets, it was observed how they were touched with the antennas and quickly removed. In the first series there was a setting, which indicates that they can be made in these buckets before applying the product, without problems. In the second and third series, the condensation on the surface of the sheet caused the drift of a small amount of product on the water and the consequent contamination of it. The 15 snails absorbing the active ingredient contained in the product died, which gives an idea of the toxicity of the samples.

    The order of highest to lowest toxicity is as follows:
    SP2> SP7> SP5> SP6> SP3> SP4 = SP1 20

    The snails did not climb the plates, since no trace was appreciated. Death was caused by water contamination, not by direct contact of the snail with the product. In order to avoid condensation, the lid had to be removed, so much heat was lost by evaporation, forcing to find a way for the snail to move along the treated surface to check if it absorbed the m.a. It contains enough to make it deadly. Due to the repellent effect of the samples, the snails did not move on the treated surface, so conclusive data were available on the possible molluscicidal effect of the composition.

    Second essay

    To obtain more information, the following experiment was carried out: treat several pieces of tile with samples SP7, SP2 and SP3. Let dry for 48 h. Then a female who was attached to the tank wall inside the water was taken and quickly before it closed the operculum was placed on top of the tile, rubbing the foot strongly against the surface. 3 series of each trial are performed with the following results:
    - SP7: 100% of deaths in 24 hours
    - SP2: 100% of deaths in 24 hours
    - SP3: 0% in 24h 40

    SP7, which contained niclosamide, was very effective. The same conclusions are used for SP2. SP3 seems to be the least toxic sample, perhaps due to its low concentration.

    The lemon aroma proved to be a good repellent, showing itself as an ecological repellent, durable and inexpensive that microencapsulated in the compositions object of the present invention constitutes a biocidal composition of great value.

    Example 8: Field application tests of biocidal compositions (emulsions) according to the present invention, against the Asian tiger mosquito (Aedes albopictus). fifty

    Aedes albopictus, commonly known as the Asian tiger mosquito, abandoned its Asian origins to colonize the world. For Europe, it represents a serious problem because of its
    great adaptability to varied habitats, both urban and rural, which favors their rapid expansion.

    The efficacy of three formulations (in the form of an emulsion) according to the present invention, containing 0.0063% (Formulation 1), 0.063% (Formulation 2) and 0.2% 5 (Formulation 3) of pyriproxyfen respectively, were evaluated. . The bioassays were performed on eggs and larvae of Ae. albopictus where the level of effectiveness of these against the adult state was determined by bioassays recommended by the World Health Organization.

    All tests were carried out in a climatic chamber with temperature control, relative humidity and photoperiod. Plastic pots were used, and the composition was dosed 2 mg / pot. For the analysis of the efficacy of the formulated assays, the evaluation of mortality and the inhibition of adult emergence has been carried out. The persistence was evaluated in four stages: 0, 2, 4, and 6 months of application.
     fifteen
    - FIRST EVALUATION (Time 0 months)
    · Formulation 1: Mortality similar to control.
    · Formulation 2 and 3: Higher mortality (23-34%).
    · Slower development of larvae.
    · 100% mortality of pupae in the 3 formulations. twenty
    - SECOND EVALUATION (Time 2 months)
    · Low mortality for the three formulations in the first 72 hours.
    · High mortality at 20 days for all three formulations, especially for Formulation 3 (77%).
    · 100% mortality of pupae in the 3 formulations. 25
    - THIRD EVALUATION (Time 4 months)
    · Low mortality for the three formulations in the first 72 hours.
    · High mortality for formulation 3 (69%) at 27 days of observation.
    · 100% mortality of pupae in the 3 formulations.
    - FOUR EVALUATION (Time 6 months) 30
    · Low mortality for the 3 formulations in the first 48 hours.
    · 33.3% mortality for formulation 2 and 26.7% for formulation 3 after 72 hours.

    In conclusion, the efficacy of the IGR is given in all three formulations equally, since no 35 pupa reaches adults (100% efficacy), and there is a greater efficacy in inhibiting growth in Formulation 3 since the mortality of L1-L2 to L3-L4 is higher than in the other two formulations.

    In short, the evolution of the different stages showed a slowdown in the cycle of the 40 larvae of the formulations tested with respect to the control group, the mortality of larvae in the treatments varied between 10% and 70% with respect to the control, which It was between 3% and 6%. However, the effectiveness could be observed until the moment of pupation whose mortality was 100% in the 3 formulations, while in the control group the adult immersion was completed. The bioassays demonstrated that the formulations have a high effectiveness so that their application can help control tiger mosquito populations.

    Example 9: Field application tests of formulations with compositions (paints) according to the present invention, against the Asian tiger mosquito (Aedes 50 albopictus).

    The efficacy of three formulations (in the form of paint) according to the present invention, which had the following active agents, was evaluated:
    - Formulation 1: Alpha-cypermethrin 0.7%, d-aletrin 1% and Pyriproxyfen 0.063%
    - Formulation 2: Diazinon 1.5%, Chlorpyrifos 1.5% and Pyriproxyfen 0.063%
    - Formulation 3: Diazinon 3% and Pyriproxyfen 0.063%

    The bioassays were performed on adults of Ae. albopictus The surfaces on which they were used were plaster (porous) and wood (non-porous). Doses of 1kg / 6m2 and 1kg / 12m2 were used. As in the previous example, the persistence was evaluated in four stages: 0, 2, 4, and 6 months of application.

    On the porous surface (plaster), at 6 months of application it was observed that the most effective formulation in both doses was the content in Formulation 1, both at 30 minutes (in this case, matched with Formulation 2 in the dose of 1kg / 12m2) as at 60 minutes. The differences between the doses were observed in that in the higher dose there was a mortality greater than 30 minutes but they are equalized at 60 minutes. The effectiveness of the 3 formulations is maintained at 6 months. fifteen

    On the non-porous surface (wood), at 6 months of application it was observed that at the dose of 1kg / 12m2 the most effective formulation is Formulation 2. The efficacy at 6 months is 100% for Formulation 2 and for Formulation 3, but not for Formulation 1.
     twenty
    At the dose of 1kg / 6m2, very good results were observed for Formulation 2 and for Formulation 1 (100% at 30 minutes). The effectiveness of the three formulations was maintained at 6 months.
