A kind of Synergistic insecticidal compositions and its application containing propargite and ethyl spinosad
Technical field
The invention belongs to pesticide field, and in particular to a kind of using propargite and ethyl spinosad as principle active component
Pesticidal combination and its application.
Background technology
Propargite (Propargite), molecular formula:C19H26O4S, chemical name:2- (4- tert-butyl benzene oxies) cyclohexyl third
Alkynes -2- base sulfites.Structural formula is:
Propargite is broad spectrum activity, efficiently, less toxic acaricide, have and tag and stomach poison function, no infiltration and systemic action.It is right
Children mite and good into mite effect, ovicidal effect is poor.Can effectively preventing and treating apple-tree, cotton, cucumber, grape, corn and soybean, kind
Tetranychid class pest on eggplant and vegetables.
Ethyl spinosad (Spinetoram), structural formula:
Ethyl spinosad is a kind of new multiple killing teichomycin insecticides produced by Dow AgroSciences, is killed by ethyl more
Two kinds of component compositions of mycin-J and ethyl spinosad-L, act on the nervous system of insect, to diamondback moth, beet armyworm, dive
The prevention effect that leaf fly, thrips, prodenia litura, bean-pod borer have had.It is with bioactivity higher, and insecticidal spectrum is wider, quick-acting
More preferably, the features such as lasting period is longer, resistance of rainwater washing against, low toxic and environment-friendly.
Insecticide variety containing single component often existing defects in pesticide control of insect:Continuous use easily produces anti-
Pharmacological property, insecticidal spectrum are narrow, it is impossible to provide comprehensive protection, peasant's drug cost height etc. for crop.It is various by two kinds or the coming year
The combination of active ingredient can overcome disadvantages mentioned above to a certain extent to a certain extent.Two kinds or two with synergistic effect
The combination mixture of kind above active ingredient, can improve preventive effect, and dosage, cost-effective with reducing active ingredient, slows down pest
Resistance, which occurs simultaneously can expand to prevent, composes, and plays that more worms are simultaneous to be controlled, reduces the use cost of peasant.
The content of the invention
It is an object of the invention to for above-mentioned various problems, in order to overcome and delay the resistance to the action of a drug to existing pesticide, expand
Big mite killing spectrum, enhancing drug effect, reduce drug cost, so as to provide a kind of prevention various crop Lepidoptera, homoptera pest and mite
The Pesticidal combination of class disease.
It is a still further object of the present invention to provide the purposes of the Pesticidal combination.
The measure of the present invention is realized by following measures.
A kind of Synergistic insecticidal compositions containing propargite and ethyl spinosad, the Synergistic insecticidal compositions with propargite with
Ethyl spinosad is principle active component, wherein, the weight ratio of propargite and ethyl spinosad is 1:60~60:1.
The more excellent weight ratio of the Pesticidal combination, wherein propargite and ethyl spinosad is 1:50~30:1.Into
The weight ratio of the preferred propargite of one step and ethyl spinosad is 1:20~20:1, still further preferably propargite kills more with ethyl
The weight ratio of mycin is 1:1~10, the most preferably weight ratio of propargite and ethyl spinosad is 1:5~10.Propargite and second
The weight ratio of Quito killing teichomycin can also be 1:10、1:5、1:10、1:2、1:3、1:1.
The weight of preparation shared by the two kinds of active principle accumulations of the Pesticidal combination, wherein propargite and ethyl spinosad
Amount is than being 0.5%~90%, preferably 1~60%.
The Pesticidal combination, using propargite and ethyl spinosad as principle active component (active ingredient) and auxiliary agent
And/or excipient is processed into any one formulation allowed on pesticide.The formulation that can be processed into be missible oil, suspending agent, aqueous emulsion,
Microemulsion, pulvis, wettable powder, dispersible oil-suspending agent and water dispersible granules etc..The auxiliary agent can use dodecyl
Benzene sulfonic acid calcium, alkylphenol polyoxyethylene ether, polyoxyethylene polyoxy propylene block compound (such as agriculture breast 33#), polyoxyethylene nonyl phenyl second
Alkene ether etc., excipient include cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water.Help above
Agent, excipient and other agriculturally known auxiliary materials can be alone or be used in combination.
The Synergistic insecticidal compositions containing propargite and ethyl spinosad prepare be used for prevent rice, wheat,
Cotton, fruit tree, vegetables, apply on tea tree in the insecticide of more Lepidopterous, homoptera pest and mite class.
It is preferred that the above-mentioned Synergistic insecticidal compositions containing propargite and ethyl spinosad are being prepared for preventing diamondback moth, diving
Leaf fly, thrips, prodenia litura, bean-pod borer, beet armyworm, red spider, tetranychid, Panonychus citri, planthopper insecticide in apply.
The present invention Synergistic insecticidal compositions antagonism mite pest have significant preventive effect, particularly with tetranychid, red spider,
The various pests that Panonychus citri etc. easily produces resistance have good preventive effect;And suppress pest to unitary agent (propargite
Or ethyl spinosad) the resistance to the action of a drug produce and at the same time can prevent plant hopper, diamondback moth etc..
The Pesticidal combination of the present invention compared with prior art, produces following beneficial effect:(1) compared with single dose, the group
Prevention of the compound to pest has notable synergistic, and prevention effect significantly improves;(2) one medicines more control, a dispenser can at the same time anti-Zhiduo County
Kind pest, reduces prevention recruitment cost;Prepared by described containing propargite and the Synergistic insecticidal compositions of ethyl spinosad
Insecticidal materials at the same time, and can prevent Homoptera, lepidoptera pest in prevention red spider mite class, especially to diamondback moth, beet armyworm,
Planthopper has good preventive effect, reaches the effect that a medicine is controlled more.(3) alternative high-toxic pesticide, and field medication is greatly reduced
Amount, effectively reduces environmental pollution and pesticide residue;(4) have concurrently quick-acting and long-acting;(5) compared with propargite single dose, produce and make
Use cost reduction;(6) suppressing pest strengthens the resistance of pesticide.
