Abstract
The invention discloses a pesticide composition containing wilfordine and coumoxystrobin as active ingredients, and applications thereof. The pesticide comprises common auxiliary agents, 0.1 to 80% of wilfordine and 0.1 to 85% of coumoxystrobin. The pesticide composition is capable of realizing relatively obvious synergistic interaction, is suitable for prevention of crop pests and diseases caused by various fungi, and is capable of controlling pests and diseases at the same time, reducing labor intensity to a certain degree and reducing cost. The pesticide composition can be used for prevention of following pests and diseases: crop pests such as nematode, cutworm, aphid, thrips and leafhopper; rice blast and banded sclerotial blight; powdery mildew, rust disease, septoria nodorum, rhynchosporium secalis davis, and black point of wheat; grape powdery mildew; powdery mildew, anthracnose, septoria lycopersici, cucumber downy mildew of cucurbites and solanaceae; and peanut cercospora leaf spot and rust disease. In addition, the pesticide composition is especially suitable for seed treatment, and prevention of germinated seeds against diseases.
Description
Technical field
The present invention relates to a kind of composition pesticide, relate in particular to a kind of composition pesticide that wilfordine and SYP-3375 be active ingredient of take, be applicable to crops pest, prevent and treat disease, strong sprout, promotion are adjusted growth, belong to biochemical pesticide field.
Background technology
The control of damage by disease and insect develops into present entomogenous fungi with killing from single desinsection, sterilization, on producing, has saved cost and labour, has saved equally in the use peasant's agriculture in the fields simultaneously originally and the activity duration, is a kind of progressive performance of Agrochemicals.As seed treatment, entomogenous fungi, with killing, can not only prevent and treat soil insect better if nematode, cutworm, crop pest are as aphid, thrips, leafhopper, again can be to rice blast and banded sclerotial blight; The powdery mildew of wheat, rust, glume blight, moire disease, black embryo disease; Grape powdery mildew; Melon and Solanaceae powdery mildew, anthracnose, spot blight, cucumber downy mildew and anthracnose are prevented; The disease such as leaf spot of peanut and rust, and time and labour saving, agricultural chemicals availability is high.Because biochemical pesticide is few, how to utilize better environmental protection type agricultural chemical to become current pesticide research person's important topic.
Wilfordine is one of main active in thunder godvine, there is the features such as insecticidal spectrum is wide, activity is high, toxicity is low, to lepidopterous diamond-back moth, cabbage caterpillar, suffixation of a nonsyllabic "r" snout moth's larva, the Asiatic migratory locust of orthoptera, dipterous midge, the corn weevil of coleoptera, the kind insects such as the tetranychus viennensis of Acarina all have stronger food refusal and toxic action, and there is paralysis insect, suppress it and grow, suppress the specificity insecticidal actions such as population augment, wilfordine is that a kind of natural insecticide ， field has good effect.
SYP-3375 is a kind of methoxy-methyl acrylate compounds, English common name: coumoxystrobin, chemical name: (E)-2-(2-((3-butyl-4-methyl-coumarin-7-Ji-oxygen base) methyl) phenyl)-3-methoxy-methyl acrylate.There is protection and therapeutic action; a kind of disinfectant use in agriculture of high-efficiency broad spectrum, to having good preventive effect by mastigomycetes, the plant disease that causes in conjunction with bacterium, sac fungi, basidiomycetes and imperfect fungus as sclerotinia rot of colza, apple valsa canker, cucumber downy mildew, powdery mildew of cucumber, rice blast, sigatoka, alternaria leaf spot of apple etc.
Summary of the invention
The object of this invention is to provide a kind of insecticidal and bactericidal composition biochemical pesticide component, high-efficiency low-toxicity that contains, to various crop effectively pest, prevent and treat disease.
Another object of the present invention is to provide by this composition pesticide for seed pelleting, prevent and treat underground pests simultaneously, disease, improves emergence rate, to future elite seed have positive meaning.
Technical solution of the present invention: for achieving the above object, the invention provides the composition pesticide that a kind of effective ingredient is comprised of wilfordine and SYP-3375, the ratio of weight and number of wilfordine and SYP-3375 is 0.1～80:0.1～85, wilfordine and the percentage by weight of SYP-3375 weight summation in composition pesticide are 5～80%, preferred weight percent is 20～60%, and all the other are in agricultural chemicals, to allow to use and acceptable auxiliary element.
Composition pesticide of the present invention can be according to well known to a person skilled in the art method, be mixed with and dispersible oil suspending agent, suspending agent, aqueous emulsion, microemulsion, suspension seed-coating agent, microcapsule formulations, wetting powder, wet seed dressing, the formulation of the applicable agricultural uses such as water-dispersible granules, missible oil, soluble liquid, tablet.
Described composition pesticide also contains usual auxiliaries, comprises wetting agent, dispersant, solvent, emulsifier, thickener, defoamer, antifreezing agent, disintegrant, binding agent, film forming agent, stabilizing agent, filler, one or more the mixing such as deionized water.According to different situations, can change to some extent, be not particularly limited.
Product of the present invention can finished product preparation form provide, insecticide-applying way can be sprayed, pesticide-clay mixture, seed dressing is spread fertilizer over the fields etc. multiple.
The present composition, the insect and the disease that can be used for preventing and treating the crops such as paddy rice, wheat, corn, soybean, cotton, peanut, beet, rape, melon and fruit.
Compared with prior art, the invention has the advantages that: 1, select biochemical pesticide, more environmental protection, more energy-conservation; 2, composite have an obvious synergistic effect, improved control efficiency; 3, delay the pesticide resistance of damage by disease and insect; 4, two kinds of active ingredients are composite, reduced agricultural chemicals usage amount, reduced cost and the pollution to environment.
Specific embodiments
In order to make object of the present invention, technical scheme and advantage clearer, the present invention is described further technical scheme of the present invention with following specific embodiment.But the invention is not restricted to following specific embodiment.
