Results of lots of indoor and outdoor tests show that the pesticide composition provided by the invention has an obvious synergistic effect, and is good in fast-acting property and long in period of preserving effects, the control effect of the pesticide composition provided by the invention on crop nematode is obviously superior to that of a single pesticide used separately, meanwhile, pesticide dosage is reduced, the pesticide residues on crops are reduced, environmental pollution is reduced, pesticide resistance of nematode is delayed and the service life of the pesticide is prolonged.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of composition pesticide that is active ingredient with rosickyite azoles and iprodione, for preventing and treating crops nematode.
Background technology
Rosickyite azoles (albendazole) is benzimidazole insecticidal bactericide.As medicine, can be used for ascarifuge, pinworm, tapeworm, whipworm, hookworm, excrement strongylid etc.Metabolism is after sulfoxide type or sulfone class in vivo, suppress parasite to the absorption of glucose, cause polypide glycogen depletion, or suppress fumaric reductase system, hinder the generation of ATP, parasite cannot be survived and breed, significant preventive effect is had to plurality of plant diseases, and have certain production-increasing function, meanwhile, also there is good control efficiency to the nematode on plant.
Iprodione (iprodione), belongs to dicarboximide class high-efficiency broad spectrum, contact killing type bactericide, and energy Profilin kinases, controls the Intracellular signals of many cell functions, comprises carbohydrate and combines the interference effect entering fungal cell constituents.Therefore, it gets final product sprouting and the generation of Antifungi spore, also can suppress mycelial growth; Be applicable to prevent and treat the diseases such as crop early defoliation disease, gray mold, early blight such as multiple fruit tree, vegetables, melon and fruit class.Meanwhile, it also has good control efficiency to Plant nematode.
Plant nematode is the very harmful pathogenic microorganism of a class, it has a very wide distribution, of a great variety, adaptive capacity to environment is strong, can colonize in the root system of plant, stem, leaf, seed, young shoot and fruit, by feeding activity, mechanical damage is caused to host plant, and rob the nutrition of host plant, especially its esophageal gland secretion can cause host plant that a series of pathology occurs, and also jointly can infect host plant with other pathogenic microorganism, cause compound disease, cause production loss.In the world, the agricultural losses that plant nematode is caused every year, up to more than 1,000 hundred million dollars, seriously constrain the development of agricultural economy.
The compounded formula screening of the present inventor to rosickyite azoles and iprodione conducts in-depth research, find that rosickyite azoles and iprodione carry out composite, within the scope of certain compound proportion, to Plant nematode, there is significant synergistic function, after further study, complete the present invention.
Summary of the invention
The object of the present invention is to provide a kind of composition pesticide containing rosickyite azoles and iprodione, be applied to the control of crops nematode.
Technical solution of the present invention: a kind of composition pesticide containing rosickyite azoles and iprodione, active ingredient is rosickyite azoles and iprodione, the weight ratio of rosickyite azoles and iprodione is 10:1 ~ 1:20, preferred weight ratio is 1:1 ~ 1:10, rosickyite azoles and iprodione gross weight percentage composition is in the composition 0.1% ~ 80%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Described composition pesticide can according to well known to a person skilled in the art method, be mixed with the application forms of the applicable agricultural uses such as microcapsule suspending agent, suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wetting powder, granule and missible oil, the production technology of various application forms all belongs to existing known technology, does not repeat them here.
Described auxiliary element is solvent, emulsifier, wetting agent, dispersant, stabilizing agent, antifreezing agent, thickener, binding agent, disintegrant, defoamer, bleeding agent, macromolecule cyst material, synergist, film forming agent, preservative and filler etc., it is all composition that is conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Composition pesticide provided by the invention, the method use usually adopting spraying, soak seed or spread fertilizer over the fields, also can adopt other operation techniques agriculturally applied as required.
Compared with prior art, the invention has the advantages that:
1, rosickyite azoles and iprodione have synergistic function, are used alone the control efficiency significantly improved nematode than single dose.
2, rosickyite azoles and iprodione two kinds of active ingredients composite, decrease Pesticide use amount, reduce use cost, alleviate pollution to environment.
3, rosickyite azoles and iprodione two kinds of active ingredients composite, the mechanism of action is different, service life of having delayed the drug-fast generation of nematode, having added agricultural chemicals.
