A kind of Synergistic insecticidal compositions and application thereof containing propargite and multiple killing teichomycin
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 multiple killing teichomycin.
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.
Multiple killing teichomycin (Spinosad), structural formula:
It is a kind of macrolides Nuisanceless high-efficient biological insecticides extracted in sugared many born of the same parents bacterium (Saccharopolysporaspinosa) zymotic fluid of thorn that multiple killing teichomycin has another name called pleocidin (Spinosad).It has stronger interior suction, tags and stomach poison function, and its mode of action is novel, can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Can effectively preventing Lepidoptera, diptera and Thysanoptera, also well can prevent and treat in coleoptera and orthoptera that some takes food the pest species of blade in a large number, poor to the control efficiency of sucking pest and mite class, therefore can use composite with mite class.
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 to existing agricultural chemicals, expand insecticidal spectrum, strengthen drug effect, reduce drug cost, thus provide a kind of prevent and treat various crop Lepidoptera, diptera, thrips and the insect pest of mite class Pesticidal combination.
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 multiple killing teichomycin, this Synergistic insecticidal compositions is with propargite and multiple killing teichomycin for principle active component, and wherein, the weight ratio of propargite and multiple killing teichomycin is 1:60 ~ 60:1.
Described Pesticidal combination, wherein the more excellent weight ratio of propargite and multiple killing teichomycin is 1:50 ~ 30:1.Preferably the weight ratio of propargite and multiple killing teichomycin is 1:20 ~ 20:1 further, then the weight ratio of further preferably propargite and multiple killing teichomycin is 1:1 ~ 10, and most preferably the weight ratio of propargite and multiple killing teichomycin is 1:5 ~ 10.The weight ratio of propargite and multiple killing teichomycin 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 multiple killing teichomycin two kinds of active principles accumulation is 0.5% ~ 90%, preferably 1 ~ 60%.
Described Pesticidal combination, with propargite and multiple killing teichomycin 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 above-mentioned Synergistic insecticidal compositions containing propargite and multiple killing teichomycin is applied in for the preparation of the insecticide preventing and treating Lepidoptera, diptera and Thysanoptera and mite class on paddy rice, wheat, cotton, fruit tree, vegetables, tea tree.This insecticide is used in particular for control diamond-back moth, beet armyworm, two spotted spider mite, 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 multiple killing teichomycin) and can diamond-back moth 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 multiple killing teichomycin prevent and treat mite roughly the same time, can lepidoptera pest be prevented and treated again, have good preventive effect to diamond-back moth, 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.
