Background of invention

Currently, for seed treatment use numerous technologies whose primary purpose is to increase the harvest. These treatments include, among other things, coating, pelletierine and/or coating on the seeds of additional coverage in the form of a film. For a long time for controlling soil-borne diseases and seed diseases of vegetable seeds used a variety of treatment fungicides in the form of Farrukh Dustov, liquids or slurries. However, the use of insecticides for treatment of seeds of vegetable crops is much less than that of seed treatment with fungicides, and moreover, treatment of seeds of agricultural crops is even less common than the processing of seeds of vegetable crops.

Modern developments in technology seed treatment focused on the application of methods of application of pesticides on seeds. Film coating was studied as a means of applying insecticides, such as benfuracarb, chlorpyrifos, Chlorfenvinphos and others. In recent times the concentration of these insecticides and other active substances present in the coating of the seeds was limited due to direct phyto-toxic action of the insecticide on seed. Application of the coating to behold the Yang of the present invention solves the problem of direct phyto-toxic action of the insecticide on seed.

Summary of the invention

In addition, the invention relates to a method of producing seeds with a coating providing a) mixing one or more binders with insecticide selected from the group including Imidacloprid, terbufos, chlorpyrifos, tefluthrin, fipronil, chlorethoxyfos, tebupirimfos and mixtures thereof, where the binder forms a matrix for the insecticide; b) applying the mixture to the seed; C) spontaneous drying the mixture to seed and d) coating the seed additional film coating.

Another embodiment of the invention is a method of protecting germinating seedlings of cultivated plants from one or more insect pests in environmental germinating seeds of field soil, providing for the application of CE is s cultivated plants insecticide effective amount of the above insecticidal coating.

The term "surrounding the germinating seed region" in the context of the present description includes the area directly surrounding the seed and young roots.

Often when handling pesticides seeds pesticides can cause physiological damage to the seed or seedling in the phyto-toxic effects of concentrated pesticide directly to the seed or to the environment surrounding the seed. The novelty of this invention lies in the fact that pesticides can be applied in the polymer matrix in pesticide effective concentrations of phyto-toxic with no harmful effects on germinating seedling. In particular, it was found that the coating of the present invention is effective for the control of insect pests, such as representatives of the order beetles (Coleoptera) and butterflies (Lepidoptera).

The most important object of the present invention is the seed, which is a coating that protects the seed or germinating seedling from physiological damage that can potentially be caused by insecticidal component of the coating.

Another object of the invention is a hybrid seed corn, which caused insecticidal coating that helps control pests of the order Coleoptera, such as representatives R. Diabrotica, in particular with flea beetle larvae dinosau.

Another object of the invention is an insecticidal seed coating, where the insecticide encapsulated in the matrix, which provides controlled release of the insecticide over a prolonged period of time.

And another object of the invention is to increase the yield of seed from the planter that the result should lead to a more uniform planting seeds.

Detailed description of the invention

The present invention relates to improved coatings for seeds, whose properties exceed the usual coatings for seeds, including insecticidal components. The invention also relates to the application of insecticides in coatings for seeds and insecticide, which when used in other forms has no effectiveness against certain insect pests may be introduced into the coating for seeds of the present invention in amounts sufficient for the manifestation of effectiveness against these insect pests, without unwanted phyto-toxic effects on the seed.

In the context of the present description to understand what their "seed coated" refers to the seed, which was subjected to the procedure by which the seed is deposited one or more adhesive layers of the coating.

The coating of the present invention includes two main components:

a) one or more binders and b) the insecticide. The binder serves as a matrix for the insecticide and is preferably present in the coating for seeds in sufficient quantity to prevent or reduce levels of phytotoxicity caused by the insecticide.

The binder component of the coating preferably includes an adhesive polymer, which may be natural or synthetic, and which does not provide phyto-toxic effect on the seed to be coated. The binder may be selected from the group including polyvinyl acetate, copolymers of polyvinyl acetate (and ethylene), polyvinyl alcohols, copolymers of polyvinyl alcohols, cellulose, including ethyl cellulose and methyl cellulose, hydroxymethylcellulose, hydroxypropylcellulose, hydroxyethylmethylcellulose, polyvinylpyrrolidone, dextrins, maltodextrins, polysaccharides, fats, oils, proteins, Arabian gum, Shallaki, vinylidenechloride, copolymers of vinylidenechloride, calcium lignosulfonate, acrylic copolymers, starches, polyvinylacetate, Seine, gelatin, carboxymethylcellulose, hits is h, the polyethylene oxide, polymers and copolymers of acrylamide, polyhydroxyethylmethacrylate, the monomers of methylacrylamide, alginate, ethylcellulose, polychloroprene and their syrups or mixtures. Preferred binders include polymers and copolymers of vinyl acetate, methyl cellulose, polyvinyl alcohol, vinylidenechloride, acrylic, cellulose, polyvinylpyrrolidone and polysaccharide. The above copolymers include polymers known in this field, for example, some of them are produced by such brands as Rhoplex™ D-60A, Methocel™ A15LV, Methocel™ E15LV, CVellosize™ QP AirFlex^TM500, Daratak™ SP 1090, Elvanol™ 85-30, Rhoplex™ AC-33-NP, Rhoplex™ B-85 and Vinamul® 18132. Particularly preferred classes of polymers include polymers and copolymers of vinylidenechloride and copolymers of vinyl acetate and ethylene.

The amount of binder in the coating may range from about 0.01 to 15% in terms of seed mass. Preferably it should be in the range of from about 0.1 to 10.0% based on the weight of the seed.

The binder should be selected so that it served as a matrix for the insecticide. Since all of the above binder can serve as a matrix, the choice of a specific binding substance is determined by the properties of the insecticide. The term "matrix" in the context of the present description denotes epreryvno solid phase, consisting of one or more binders, which contains vacancies, voids or space occupied by the insecticide and filler. The term "matrix" is given a broad meaning and implies that he may be a matrix system, tank system or microencapsulated system. Typically, the matrix system includes an insecticide and a filler uniformly dispersed in the polymer, but the reservoir system comprises a single insecticidal phase particles or droplets of insecticide, physically dispersed in the polymer phase, limiting the speed. Microencapsulation involves coating on small particles or liquid droplets. The concept of "microencapsulation" applies not only to coated particles or drops, but also to dispersions in solid matrix. Not limited to the specific encapsulation system (matrix, reservoir or microencapsulation), the term "matrix" includes all of the above systems.

The invention also relates to the use in insecticidal coatings fillers, such as absorbent or inert fillers. It was found that the use of fillers in coatings is especially effective for protection of the seed in stressful situations. Fillers for such compositions is known in this field and may include the performance of wood flour, clay, activated charcoal, sugar, diatomaceous earth, flour, cereals, powdered inorganic solids, calcium carbonate, etc. of Clay and inorganic solids which can be used include calcium bentonite, kaolin, white clay, talc, perlite, mica, vermiculite, silica, quartz powder, montmorillonite and mixtures thereof. Sugar, which can be used include dextrin and maltodextrin. Flour of cereals includes wheat flour, oat flour and barley flour. Preferred fillers include diatomaceous earth, perlite, silica and calcium carbonates and their mixtures. For example, the most preferred is a product containing diatomaceous earth and amorphous silicon dioxide, marketed by the company Celit Corporation (Celite™). Specialist in this field should be obvious that suitable materials are not limited by the list and that other known fillers may be used depending on the seed, which must be coated, and insecticide included in the coating composition.

The filler is chosen so that it could provide the appropriate microclimate for seed, for example, the filler is used to raise the application rate of the active substance and for regulating the controlled release of active substances is. The filler contributes to the preparation of coating or coating process on the seed. Its effect varies, as in some cases preparative form of insecticide may contain a filler. The number of the used filler can vary, but usually the weight of the components of the filler should be approximately 0.005 to 70% by weight of the seed, more preferably from about 0.01 to 50% and most preferably from about 0.1 to 15%. The filler may be added to the coating according to the invention together with insecticidal component. In the specific examples given in the present description, use readily available commercially available compositions known insecticides, in which the filler is included in the composition.

Acceptable insecticides include insecticides selected from azoles, such as triazoles, azines, pyrethroids, organophosphorus compounds, carbamoyloximes, pyrrole, pyrazoles, pyridines, amidino, galogenidov-tion of hydrocarbons and carbamates, and their combinations and derivatives. Particularly preferred classes of insecticides include insect growth regulators (e.g., Mimic™), organophosphorus insecticides (e.g., Fortress™), phenylpyrazoles and pyrethroids. Preferred insecticide include such well-known compounds as terbufos, chlorpyrifos, fipronil(Regent™ ), chlorethoxyfos, tefluthrin, files, fenoxycarb, giovanola (Aware™), pymetrozine (Chess™), carbofuran, tebupirimfos and Imidacloprid (Gaucho™, Confidor™, Admire™), including analogues of Imidacloprid, such as (substituted or unsubstituted) nitro, oxo - or lanzamiento guanidine, enamines, aminomorpholine, piperazines, aminopiperidine, oxopiperidine, oxadiazine, oxopyridine, diazocyclopentadiene, diazolidinyl and morpholines. Most preferred are Imidacloprid and analogues of Imidacloprid, for example, described in patent US 5034542, terbufos, chlorpyrifos, fipronil, tefluthrin, chlorethoxyfos, tebupirimfos and their mixtures, for example, Imidacloprid and tefluthrin.

It was found that for seed treatment according to the present invention is especially preferred are compounds of General formula (I):

where And denotes unsubstituted or substituted by 1-4 substituents, aromatic or non-aromatic monocyclic or bicyclic heterocyclic radical, where from 1-2 substituents And can be selected from the group comprising Gialos₁-C₃alkyl, cyclopropyl, galactolipid,₂-C₃alkenyl,₂-C₃quinil, Gialos₂-C₃alkenyl, halo, C₂-C₃quinil, Gialos₁-C₃alkoxy, C₁-C₃alkylthio, Gialos_{1 -C3alkylthio, aryloxy, propargyloxy, allylthio, propargite, haloalkoxy, haloalkylthio, cyano and nitro, and from 1-4 substituents And can be selected from the group comprising From1-C3alkyl, C1-C3alkoxy and halogen;}

R denotes hydrogen, C₁-C₆alkyl, panels₁-C₄alkyl, C₃-C₆cycloalkyl,₂-C₆alkenyl or₂-C₆quinil; and

X denotes N-NO₂or N-CN

or, if necessary, their tautomers, in each case in free form or in salt form.

Especially preferred insecticide from compounds of General formula (I) is a compound in which And the means

and X denotes N-NO₂, i.e. the compound of formula II:

The compound of formula II can be applied individually or in combination with other pesticides, for example with tefluthrin. Also suitable are other combinations of pesticides, such as pyrethroids and organophosphate insecticides.

Also can include plant growth regulators, such as methoprene and hydroprene. They are well known to specialists in this field.

The amount of insecticide in the coating may vary within wide limits depending on the type of seed and the specific active substance, but in Salomone is about 0.005 to 50% in terms of seed mass. Preferably, the percentage of insecticide is approximately from 0.01 to 40%. Most preferably, the percentage of insecticide is approximately from 0.05 to 20.0%. In particular, for chlorpyrifos, it is in the range of about 0.5 to 20.0%, preferably from about 1.0 to 15%; for tefluthrin it is in the range of from about 0.01 to 10.0%, preferably about from 0.05 to 5.0%; for tebupirimfos it is in the range of approximately from 0.01 to 5.0%, preferably from about 0.05 to 3.0%; for fipronil it is in the range of from about 0.01 to 10.0%, preferably about from 0.05 to 5.0%; and for Imidacloprid and insecticides, which are analogues of Imidacloprid, it is the range of from about 0.01 to 10.0%, preferably about from 0.05 to 5.0%.

Specialist in this field should be obvious that the exact amount should vary depending on the size of the seed that should be coated. The insecticide coating should not inhibit germination of the seed and should maintain efficiency at all times during the life cycle of insect targets that cause damage to cultivated plants. Specialist in this field should be obvious that this time, in addition to other factors should vary depending on the type of insect target. Typically, the opening should remain effective for about 0-120 days after sowing. The floor under the present invention should contain the number of insecticide, which has insecticidal activity. The concept of "insecticide an effective amount of insecticide in the context of the present description denotes the number of insecticide, which should destroy insect pests larvae or pupae or should significantly reduce the amount of damage or slow the appearance of new lesions caused by insect pests.

As applied to cover the insecticidal component is used, the composition of the oil type and the coating is only a small amount of filler or it is not present, it may be necessary to speed up the drying process by drying the composition. This is an optional procedure can be carried out using methods well known to specialists in this field, and involves adding calcium carbonate, kaolin or bentonite clay, perlite, diatomaceous earth or any absorbent material, which takes place simultaneously with the introduction of layer insecticidal coating in order to adsorb oil or excess moisture. The amount of calcium carbonate or related compounds for drying portion of the solution should be from about 0.5 to 10.0 wt.%

Cover, poluchennogo the invention, have the ability to perform slow release insecticide by diffusion or passage through the matrix into the environment.

In fact, according to the invention can be processed seed of any crop plants, such as seeds of cereal, vegetable, ornamental and fruit crops. In particular, cultivated plants, the seeds of which can be processed are selected from the group including corn (sugar and ordinary), soybeans, wheat, barley, oats, rice, cotton, sunflower, alfalfa, sorghum, rapeseed, sugar beet, Brassica spp., tomatoes, beans, carrots, tobacco, and flowers such as violet, a touch-me-not (Impatiens, Petunia and geranium. The most preferred culture, the seeds of which can be processed include corn and soybeans.

Preferred pest target include soil-inhabiting insects of the orders:

Coleoptera, first of all, Diabrotica spp. (blaska Dlinnaya Western, southern and Northern), for example, D. balteata, D. virgifera, D. undecimpunctata and D. longicornis; Melanotus spp. (the larva of scale corn); Phyllophaga spp. (cerubidine larvae, wireworms and false wireworms); Limonius spp. (the larva of scale sugar beet) and Agrrotes spp. (larvae of scale wheat, larvae of the beetle and zeroed);

Diptera, first is this Hylemya spp. (larva growth flies) and Tetanops spp. (larva root flies sugar beet);

Homoptera, first of all, Pemphigus spp. (root aphid sugar beet) and Aphis spp. (root aphid corn).

Insecticidal coating especially suitable for inclusion of high concentrations of insecticide needed to fight, usually with resistant species such as flea beetle larvae dinosau, but at the same time it prevents unwanted phyto-toxic effect associated with high concentrations of insecticide.

Preferred organisms targets include Diabrotica spp., Agrotis ypsilon; Melanotus cribulosus; Hylemya cilicrura; Agonoderus lecontei; Feltia subgotica and Phyllophaga rugosa.

According to another variant implementation in insecticide solution may include a plasticizer. Generally, plasticizers are applied to obtain a film, which makes the layer insecticidal coating more flexible, improves adhesion, spreading and increases the processing speed. Increased elasticity of the film is important to minimize damage, destruction or flocculation during processing or during planting. Can be applied in numerous plasticizers, however, the most preferred plasticizers include polyethylene glycol, glycerin, butylbenzylphthalate, picolanate and related compounds. The percentage of the plasticized the RA layer insecticidal coating may be from about 0.1 to about 20%.

In addition to the layer insecticidal coating seeds can be processed by one or more of the following ingredients: other pesticides, including fungicides and herbicides; antidotes protective agents) for herbicides; fertilizers and/or biological control agents. These ingredients can be added as a separate layer or may be added in a layer of insecticide coverage.

Suitable pesticides include pesticides that are listed in the present description and are listed in the Pesticide Manual, 9th ed. editor Charles Worthing, published by the British Crop Council, which is incorporated into this description by reference.

Fungicides can be applied to the seed before applying the above coating. Application of fungicide in the form of dust, suspensions or the like is a well known in this field treatment method seed and the resulting layer is not treated as a coating layer in the context of the present description. Examples of acceptable fungicides include Captan (N-(trichloromethyl)thio-4-cyclohexane-1,2-dicarboximide); thiram (tetramethylthioperoxydicarbonic diamed); metalaxyl (methyl N-(2,6-dimetilfenil)-N-(methoxyacetyl)-DL-alaninate); fludyoksonil (4-(2,2-debtor-1,3-benzodioxol-4-yl)-1H-pyrrol-3-carbonitrile); and oxadixyl (N-(2,6-dimetilfenil)-2-methoxy-N-(2-oxo-3-oxazolidinyl)ndimethylacetamide). The specialist in this area other known effective Fung is tidy, suitable for combating harmful pathogens that not only solve the problem in a specific area in which to grow the seeds are coated, but can also be used to protect seeds during storage before planting.

The amount of insecticide that can be added varies depending on the activity of the active substance, but generally can range from about 0.001 to about 10% in terms of seed mass and preferably about from 0.01 to 2.0%. However, in specific cases, these quantities can be increased or decreased.

Acceptable herbicides include herbicides selected from carbamates, thiocarbamates, acetamido, in particular chloracetamide, triazines, dinitroanilines, ethers of glycerin, pyridazinones, orallow, phenoxypropionic, ureas and benzoic acids and their derivatives. Suitable antidotes include, for example, benzoxazin, benzhydryl derivatives, N,N-diallylmalonate, various disloyally, derivatives oxazolidinyl and diazolidinyl, alanon, derivatives of naphthalene anhydride and Joksimovi derivatives.

Acceptable biological control agents are bacteria RR Rhizobium, Bacillus, Pseudomonas and Serratia, and mushrooms RR Trichoderma, Glomus and Gliocladium and mycorrhizal fungi.

The above compounds are given only as examples and not to what should be considered as an exhaustive list of compounds which can be used in the layer insecticidal coating or other coating layers.

The coating according to the invention can be applied to conventional methods of coating. In addition, professionals in this field there are various machines for coating. Three well-known method include the use of drum machines and tuck the methods based on the use of fluidized bed. Can also be applied by other methods, for example, based on the application of the current layers. Seeds can be prior to coating are separated by size. After coating the seeds are dried and then optionally separated by size by moving in the sorting machine. These machines are well known in this field, for example, represent a conventional machine, which is used in industry for sorting seed corn.

Film-forming compositions intended for shelling seeds coated, well known in this area and additional film coating can be optionally applied on the seeds with a coating according to the present invention. Additional film coating protects the layers of the coating, and optionally allows for easy identification of treated seeds. Typically, the additive is dissolved or dispel the display in the liquid adhesive, usually in the polymer, in which the seeds are dipped or applied to seeds by spraying before drying. In another embodiment, can be applied powder adhesive. For additional coverage various suitable materials, including but not limited to, methylcellulose, hypromellose, dextrin, gums, waxes, vegetable or paraffin oil; water-soluble or dispersible in water, polysaccharides and their derivatives, such as alginates, starch and cellulose; and synthetic polymers such as polyethylene oxide, polyvinyl alcohol and polyvinylpyrrolidone and copolymers and related polymers, and mixtures thereof.

Additional coverage can be added to other materials, including optional plasticizers, dyes, brighteners and surfactants, such as dispersing agents, emulsifiers and contributing to the fluidity agents, including, for example, calcium stearate, talc and vermiculite. For film coating can be added pesticides, such as fungicides, however, it was found that fungicides, which are initially processed seeds, provide a higher level of protection than when they are added with additional coating. For film coating can be applied to the above-described methods of coating with p the power fluidized bed or drum.

Additional film coating is applied to the seed in the amount of about 0.01 to about 20% in terms of seed mass. Preferably in the range of from about 0.01 to about 10.0% and most preferably in the range of from about 0.01 to 5.0 percent. The preferred solution should vary depending on the specific active substance. The preferred film for additional coverage may include methylcellulose, hypromellose, polyvinyl acetate, PEG and their mixtures. In addition, depending on the type of insecticide film for additional coverage may include the connection, which is a repellent for birds. Such compounds are known in the relevant field and include, for example: anthraquinone, methylanthranilate, capsaicin and oxidized tetracyclic triterpenoids (also called Cucurbitaceae), which are described in U.S. patent 5292533. In addition, these compounds may also be added to the layer insecticide coverage.

Depending on germplasm and seed plants, which must be coated, resulting in additional processing prior to coating, such as a lock or treatment with growth regulators or biological means of struggle, can be obtained other valuable properties.

When the lock seed treatment is anywayt to achieve humidity, sufficient to accelerate germination, but insufficient to cause premature germination. Examples of steeping methods known in this field and includes locked in the drum and the speed locked.

The growth regulators that can be added to the coating include auxins, cytokines, gibberellin, ethylene, abscisic acid, IAA (indelicacy acid), NAA (α-naphthyloxy acid), IBA (indolylmethane acid), ethephon, ndimethylacetamide, maleic hydrazide, diminished and similar compounds. Processing biological means can also be used to improve the characteristics of the seeds and to help to fight harmful organisms.

Seeds that are coated according to the invention have the following advantages.

They have less risk to agricultural employee when handling and contact with them as a result of reduced contact with the powdered drug. Pesticides can be made uniform, and thus prevents the loss of the pesticide during transportation and processing. Reduced phytotoxicity against seeds and developing seedlings and consequently no adverse effects on germination, emergence and development of seedlings. In addition, the introduction of pesticides, especially insecticides, the middle is the area of supply of soil insects, can improve the effectiveness of pest control.

Below, specific embodiments of the invention are given only as an example.

In each geographic area for each option processing using plot, representing two rows 10 feet in length at a distance of 30 inches from each other, the experiments are performed in four replicates. On both sides of the maize plants in the row with inter-row cultivator contribute fail diapause larvae 1 age of a flea dinosau West at the rate of 800 eggs per foot of row. Making insect larvae exercise, when corn seedlings are about at the stage two leaves. Larvae placed approximately two inches from the side of maize plants and to a depth of two inches from the soil surface. Plots cultivated according to conventional agricultural practice until the plants cook who rouses the bloom stage. In the late phase of brown silk from each plot to be selected for 10 consecutive roots of plants. For this purpose, the stems are cut at a distance of approximately 12 inches above the soil line. Each root is washed and after washing the roots and evaluate them on a scale of 1-6, using the method of scoring roots, adopted in Iowa Root Rating Method), which was developed at the University of Iowa (Hills and Peters, 1971) and is usually applied in areas of maize cultivation. According to this scale, a score of 1 corresponds to no damage, or only a very small nutrition-related insect scars; a score of 2 corresponds to the visible food insects scars, but the roots are not thristy at a distance of 1.5 inches from the plant; a score of 3 corresponds to a variant, when multiple roots ugrasena at a distance of 1.5 inches from the plant, but none of equivalents full root node is not destroyed; a score of 4 corresponds to a variant, when one root node completely destroyed; a score of 5 corresponds to a variant, when the two root node completely destroyed, and a score of 6 corresponds to option, when three or more root nodes completely destroyed. The notion of "completely destroyed the root denotes the root, split at a distance of 1.5 inches from the base. Split the roots should not happens the ü from one node, but all derived roots must meet the equivalent of the full site to be considered destroyed node. Average results for scoring roots below in table 3.

In addition, to assess the role of insecticidal seed coating in the fight against blascoe dinosau conduct biological tests in growth chamber and in the greenhouse. For experience in growth chamber seed corn sown in a Cup containing 16 ounces of garden mix Jiffymix, and give rise within 2 weeks. In Jiffymix about the roots of maize contribute 20 newborn larvae flea dinosau and allow them to eat for about 2 weeks. Then conduct the counting of larvae and determine the mortality of larvae in %. The root of each plant corn is washed and after washing the roots and evaluate them on a scale of 1-6, using the method of scoring roots, adopted in Iowa Root Rating Method), which was developed at the University of Iowa (Hills and Peters, 1971). Some of the results are shown in table 4. Experience in the greenhouse are using pots with a volume of 2 gallons, filled with soil with a particle size of 20 mesh for growing corn in the field. In each vegetation vessel, when corn reaches the stage of 4-5 leaves, put on 40 larvae flea dinosau and allowed to feed for 3 weeks. The root of each plant corn is washed and after washing the roots and evaluate them on a scale of 1-6, using the method of scoring roots, adopted in Iowa Root Rating Method), which was developed at the University of Iowa (Hills and Peters, 1971). Some of the results are shown in table 4.
