Description

A kind of Synergistic insecticidal compositions and application thereof containing propargite and cycloprothrin
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 cycloprothrin.
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.
Cycloprothrin (Cyclopropanecarboxylicacid), structural formula:
A kind of low toxicity pyrethroid insecticides of cycloprothrin, based on action of contace poison, has certain stomach poison function, without interior suction and fumigation action.This product insecticidal spectrum is wide, except the control being mainly used in rice grub, also can be used for the control of other insect such as dry crop, fruit and vegetables, has repellent and Antifeedant Effects, to plant safety.Be mainly used in water prevention Lissorhoptrus oryzophilus Kuschel, Lissorhoptrus oryzophilus Kuschel snout moth's larva, rice leafhopper, cabbage caterpillar, prodenia litura, aphid, soybean pod borer, tea olethreutid, Scirothrips dorsalis, fruit tree budworm, citrus leaf-miner, peach fruit borer, cotton bollworm etc.
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 and kill mite spectrum, strengthen drug effect, reduce drug cost, thus provide a kind of Pesticidal combination preventing and treating various crop Acarina, Semiptera, lepidopterous 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 Pesticidal combination for propargite and cycloprothrin, this Synergistic insecticidal compositions is with propargite and cycloprothrin for principle active component, and wherein, the weight ratio of propargite and cycloprothrin is 1:60 ~ 60:1.
Described Pesticidal combination, wherein the more excellent weight ratio of propargite and cycloprothrin is 1:50 ~ 30:1.Preferably the weight ratio of propargite and cycloprothrin is 1:20 ~ 20:1 further, then the weight ratio of further preferably propargite and cycloprothrin is 1:1 ~ 10, and most preferably the weight ratio of propargite and cycloprothrin is 1:5 ~ 10.The weight ratio of propargite and cycloprothrin 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 cycloprothrin two kinds of active principles accumulation is 0.5% ~ 90%, preferably 1 ~ 60%.
Described Pesticidal combination, with propargite and cycloprothrin 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 cycloprothrin is preparing the application of insecticide of the Acarina prevented and treated on paddy rice, fruit tree, soybean, tea tree, vegetables, cotton, Semiptera, lepidoptera pest.Described lepidoptera pest is cabbage caterpillar, cotton bollworm, leaf miner, beet armyworm, and Hemipteran pest is aphid, and mite pest is citrus red 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 cycloprothrin) and can the lepidoptera pests such as soybean pod borer 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 cycloprothrin prevent and treat mite roughly the same time, lepidoptera pest can be prevented and treated again, there is good preventive effect to cotton cotton bollworm, paddy rice weevil, soybean pod borer, cabbage caterpillar 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.
