Description
Technical field
The present invention relates to technical field of pesticide, be specifically related to a kind of nicotinoids seed treatment composition.
Background technology
Anabasine insecticide is as Imidacloprid, Acetamiprid, Diacloden, Nitenpyram, MTI-446, thiacloprid, clothianidin etc., its mechanism of action is mainly by Selective Control insect nerve system nicotinic acetylcholine esterase acceptor, block the neural normal conduction of insect heatstroke, thus cause insect to occur paralysis and then death.Because this insecticides has unique mechanism of action, cross resistance is not had with common insecticides, it not only has efficiently, absorption in wide spectrum and good root, tag and stomach poison function, and it is low to mammalian toxicity, can effectively preventing and treating the insects such as Homoptera, coleoptera, diptera and Lepidoptera, also having good activity to preventing and treating by conventional pesticides the insect developed immunity to drugs.Anabasine insecticide both can be used for cauline leaf process, also can be used for soil, seed treatment.
Benzimidazole germicide (benzimidazole fungicide) has the class organic bactericide that the benzimidazole ring of bactericidal activity is parent, this compounds nearly all shows interior suction bactericidal activity, wherein representative compound has benomyl, carbendazim, blue or green bacterium spirit, thiophanate, thiophanate-methyl etc., its in plant corpus or near plant through metabolism activation, become tolimidazole-2-carbamate, i.e. carbendazim, or be similar to their compound, thus show bactericidal activity, and probenazole, furidazol, after azoles bacterium spirit etc. is absorbed by plants, conduct to infection site, and present bactericidal action.Benzimidazole germicide is applied to agricultural the earliest, is applicable to the corps diseases such as vegetables, melon and fruit, wheat.Be applied to mainly containing of industrial circle: probenazole, furidazol, carbendazim, benomyl and thiophanate-methyl.In antibacterial and mouldproof, its maximum feature is exactly pretty good to antifungal effect, but general or invalid to bacterium.Secondly, benzimidazole germicide safety is pretty good.
Antibiotics bactericide is as jinggangmeisu, kasugarnycin, polyoxin, agricultural streptomycin etc., derive from microorganism produce secondary metabolite and with produce bioactivator for model, carry out Prof. Du Yucang or structure of modification, become artificial semisynthetic product.This kind of antibiotic major part has interior absorption energy, efficient, selectivity strong, have treatment and protective effect, biological degradation is fast, nuisanceless, to advantages such as person poultry safeties.
Seed coat agent (seed treatment formulation) is a kind of for crop seed process, the pesticidal preparations with film forming characteristics.Usual seed coat agent is processed into by active component, carrier and auxiliary agent, directly or after dilution can be coated on the surface of the seed, be formed and have some strength and infiltrative diaphragm preparation.It and for the difference such as emulsifiable concentrates for agricultural chemicals, pulvis, suspending agent of seed treatment, seed coat agent wraps in the surface of the seed to form specific coating membrane, the imbibition and not dissolved in soil of this tunic, normally germinate required moisture and air of seed is allowed to pass through, make active component slow releasing, have and kill soil insect, prevent seed-borne fungi and sprout term disease, promotion seedling healthy growth, improve percentage of seedgermination, reduce Pesticide use amount, improve the work energy such as output, thus reach reduce environmental pollution, object that preventing disease pest control is kept a full stand of seedings.
Since the thirties in 20th century, Britain Germains seeds company developed Dry crop seed coat agent first, the Developing Application development of seed coat agent rapidly, the country such as Britain, the U.S., Japan, China has developed the seed coat agent comprising the crops such as cotton, corn, soybean, wheat in succession, and wherein the overwhelming majority achieves significant economic benefit and social benefit through applying.Nicotinic insecticide mainly acts on the nAChR ligands of insect, there is the feature of high-efficiency low-toxicity, from Imidacloprid since listing in 1991, in short 10 years, this insecticides becomes the insecticide series that the world's biocides market after organic phosphates, pyrethroid occupies the 3rd.Compared with other crop seed coat agent, the research and development of dressing agent for rice is just relatively slower relative to other crop, and its key factor is thin film coating material poor water resistance.Conventional material is the water soluble polymer with cohesiveness and film forming, as the high molecular polymers such as polyvinyl alcohol, carboxymethyl cellulose, gum Arabic, gelatin, xanthans, starch are not suitable for dressing agent for rice.Therefore, the material with certain hydrophobic effect is adopted, as acrylate copolymer, cellulose derivatives (ethyl cellulose, cellulose acetate-butyrate, hydroxypropyl methylcellulose) can effectively solve the problem as film forming agent material.
Summary of the invention
The object of the present invention is to provide a kind of seed treatment composition comprising nicotinic insecticide, azoles fungicide or Antibiotics fungicidal activity component, it is by two kinds of composite uses of active component, thus improve control corps diseases effect, preferred carrier, the formulated insecticide/bactericides seed treatment of auxiliary agent is aided with again for said composition, improve the resistance to water of filming performance and film, make sustained release, extend the lasting period of active component medicine, the dosage of agricultural chemicals is reduced, decreases residue of pesticide and the pollution to environment.
Above-mentioned seed treatment is mainly used in control and propagates by seed and Soil infection cause harm bakanae disease of rice, banded sclerotial blight, rice fulgorid, rice blast and pythium rot and maize head smut, base rot disease and grub etc.
To achieve these goals, present invention employs following technical scheme:
