The invention discloses a synergistic insecticidal composition containing propargite and silafluofen and application thereof. The insecticidal composition takes the propargite and the silafluofen as main effective components, wherein the weight ratio of the propargite to the silafluofen ranges from (1:60) to (60:1). The composition provided by the invention can be used for preventing and treating a plurality of types of injurious insects, has a remarkable synergistic effect and can be used for expanding the insecticidal spectrum; the synergistic insecticidal composition has relatively high activity on red spiders, spider mites, panonychus ulmi, cotton bollworms, european corn borers, beet armyworms, rice planthopper, prodenia litura and the like of cereal crops, fruit trees, flowers, cotton and vegetables; the dosage of pesticides on crops is reduced, the residual amount of the pesticides on the crops is reduced and environmental pollution is alleviated; and the synergistic insecticidal composition is safe to human and livestock and has good environment compatibility, and the injurious insects cannot easily have drug resistance.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of be principle active component Pesticidal combination and the application thereof of propargite and silicon ether chrysanthemum ester.
Background technology
Propargite (Propargite), molecular formula: C
19h
26o
4s, chemical name: 2-(4-tert-butyl benzene oxy) cyclohexyl propine-2-base sulfite.Structural formula is:
Propargite is broad spectrum activity, efficient, low toxicity miticide, has and tags and stomach poison function, without infiltration and systemic action.If to children mite with to become mite effective, ovicidal effect is poor.Can effectively preventing and treating apple-tree, cotton, cucumber, grape, corn, soybean, spider mite kind insect on tomato and vegetables.
Silicon ether chrysanthemum ester (Silafluofen), structural formula:
Silicon ether chrysanthemum ester is siliceous pyrethroid insecticides, and effect, close to ether chrysanthemum ester, can be used for paddy rice, cotton-plant pest-insects control.Rapidly, insecticidal spectrum is wide, and ichthyotoxin is very low, is expected to use in paddy field in effect.Be applicable to, on control paddy rice, vegetables, cotton, to Homoptera Delphacidae special efficacy, also have good effect to various pests such as Lepidoptera, Semiptera, orthoptera, coleoptera, diptera and Isopteras simultaneously.Especially remarkable to the control efficiency of rice hoppers.
Containing the insecticide variety of single component often existing defects in agricultural chemicals control of insect: use is easily developed immunity to drugs continuously, and insecticidal spectrum is narrow, and can not provide comprehensive protection for crop, peasant's drug cost is high.Being combined in and can overcoming above-mentioned shortcoming to a certain extent to a certain extent by two kinds or various active component in the coming year.There is two kinds of synergistic effect or the combination mixture of two or more active component, can preventive effect be improved, reduce active ingredient ground dosage, cost-saving, slow down pest resistance and to occur and can expanding prevention spectrum, play that many worms are double to be controlled, reduce the use cost of peasant.
Summary of the invention
The object of the invention is to for above-mentioned various problem, in order to overcome and delay pesticide resistance, expansion insecticidal spectrum, enhancing drug effect, the reduction drug cost to existing agricultural chemicals, thus provide a kind of Pesticidal combination preventing and treating various crop Homoptera, Lepidoptera, mite class damage by disease and insect.
A further object of the invention is to provide the purposes of this Pesticidal combination.
Measure of the present invention is realized by following measures.
Containing a Synergistic insecticidal compositions for propargite and silicon ether chrysanthemum ester, this Synergistic insecticidal compositions is with propargite and silicon ether chrysanthemum ester for principle active component, and wherein, the weight ratio of propargite and silicon ether chrysanthemum ester is 1:60 ~ 60:1.
Described Pesticidal combination, wherein the more excellent weight ratio of propargite and silicon ether chrysanthemum ester is 1:50 ~ 30:1.Preferably the weight ratio of propargite and silicon ether chrysanthemum ester is 1:20 ~ 20:1 further, then the weight ratio of further preferably propargite and silicon ether chrysanthemum ester is 1:1 ~ 10, and most preferably the weight ratio of propargite and silicon ether chrysanthemum ester is 1:5 ~ 10.The weight ratio of propargite and silicon ether chrysanthemum ester can also be 1:10,1:5,1:10,1:2,1:3,1:1.
Described Pesticidal combination, wherein the weight ratio of propargite and the shared preparations of silicon ether chrysanthemum ester two kinds of active principles accumulation is 0.5% ~ 90%, preferably 1 ~ 60%.
Described Pesticidal combination, with propargite and silicon ether chrysanthemum ester for principle active component (active component) and auxiliary agent and/or excipient are processed into any one formulation that agricultural chemicals allows.The formulation that can be processed into is missible oil, suspending agent, aqueous emulsion, microemulsion, pulvis, wetting powder, dispersible oil-suspending agent and water dispersible granules etc.Described auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc., excipient comprises cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other agriculturally known auxiliary material can be alone or and use.
The described Synergistic insecticidal compositions containing propargite and silicon ether chrysanthemum ester is applied in the insecticide for the preparation of the Homoptera prevented and treated on cereal crop, fruit tree, flowers, cotton, tea tree, vegetables, Lepidoptera, mite pest.
Described lepidoptera pest is cotton bollworm, leaf miner, and homoptera pest is plant hopper, and mite pest is two spotted spider mite, beet armyworm, tetranychid, Panonychus citri.
Synergistic insecticidal compositions antagonism mite pest of the present invention has significant preventive effect, especially has good preventive effect for the easy various pests producing resistance such as tetranychid, two spotted spider mite, Panonychus citri; And suppress insect produce the pesticide resistance of unitary agent (propargite or silicon ether chrysanthemum ester) and can cotton bollworm etc. be prevented and treated simultaneously.
Pesticidal combination of the present invention compared with prior art, produces following beneficial effect: (1), compared with single dose, the control of said composition to insect has notable synergistic, and control efficiency significantly improves; (2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; By the described insecticidal materials prepared containing the Synergistic insecticidal compositions of propargite and silicon ether chrysanthemum ester prevent and treat mite roughly the same time, Homoptera, lepidoptera pest can be prevented and treated again, there is good preventive effect to cotton cotton bollworm, small brown rice planthopper and beet armyworm especially, reach the effect that a medicine is controlled more.(3) alternative high-toxic pesticide, and significantly reduce field dosage, effectively reduce environmental pollution and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compared with propargite single dose, produce and use cost reduction; (6) insect is suppressed to strengthen the resistance of agricultural chemicals.
