The insecticidal composition takes propargite and chlorpyrifos as main effective components and the weight ratio of propargite to chlorpyrifos ranges from (1:60) to (60:1). The composition disclosed 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 a plurality of types of chewing type and piercing-sucking type mouthpart injurious insects on rice, wheat, cotton, fruit trees, vegetables and tea trees; the dosage of pesticides is reduced, the residual amount of the pesticides on 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 chlopyrifos.
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.
Chlopyrifos (chlorpyrifos), structural formula:
Chlopyrifos (having another name called chlorine pyrazothion, Le Siben, Chlorpyrifos) is acetylcholinesteraseinhibitors inhibitors, belongs to thiophosphate insecticides.There is stomach toxicity, tag, fumigate triple role, all there is favorable effect to chewing type multiple on paddy rice, wheat, cotton, fruit tree, vegetables, tea tree and sucking pest.Insecticidal spectrum is wide, and the organic matter be easy in soil combines, to soil insect special efficacy.It is the main alternative pesticide species after China's forbidding high-toxic pesticide in 2007, and domestic production scale is large, and good disinsection effect is water prevention rice pest: the main pesticide species of rice leaf roller, rice fulgorid.
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 chewing type and sucking mouth parts insect pest.
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 chlopyrifos, this Synergistic insecticidal compositions is with propargite and chlopyrifos for principle active component, and wherein, the weight ratio of propargite and chlopyrifos is 1:60 ~ 60:1.
Described Pesticidal combination, wherein the more excellent weight ratio of propargite and chlopyrifos is 1:50 ~ 30:1.Preferably the weight ratio of propargite and chlopyrifos is 1:20 ~ 20:1 further, then the weight ratio of further preferably propargite and chlopyrifos is 1:1 ~ 10, and most preferably the weight ratio of propargite and chlopyrifos is 1:5 ~ 10.The weight ratio of propargite and chlopyrifos 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 chlopyrifos two kinds of active principles accumulation is 0.5% ~ 90%, preferably 1 ~ 60%.
Described Pesticidal combination, with propargite and chlopyrifos 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 chlopyrifos can for the preparation of the insecticide preventing and treating multiple chewing type and sucking pest on paddy rice, wheat, cotton, fruit tree, vegetables, tea tree.
The Synergistic insecticidal compositions of propargite and chlopyrifos should be contained especially for the preparation of the application prevented and treated in the insecticide of Acarina, Homoptera, Lepidoptera, coleopteran pest, wherein, homoptera pest comprises rice fulgorid, lepidoptera pest comprises cotton bollworm, cotten aphid, mythimna separata, coleopteran pest comprise wireworm, and acarina pest comprises 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 chlopyrifos) and can rice fulgorid 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 chlopyrifos prevent and treat mite roughly the same time, Lepidoptera, Homoptera, coleopteran pest can be prevented and treated again, there is good preventive effect to rice leaf roller, rice fulgorid 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.
