Abstract

The invention discloses a kind of Synergistic insecticidal compositions and application thereof containing propargite and cyfluthrin, the Pesticidal combination is using propargite and cyfluthrin as principle active component, wherein the weight ratio of propargite and cyfluthrin is 1:60~60:1.The present composition can prevent various pests, and there is apparent synergistic effect, and insecticidal spectrum is expanded, there is greater activity to the acarids such as cotton, fruit tree, vegetables, cereal crop Homoptera, Lepidoptera, acarina pest and red spider, tetranychid, Panonychus citri;And reduces pesticide usage amount, reduce residual quantity of the pesticide on crop, alleviate environmental pollution;To safety of human and livestock, Environmental compatibility is good, pest is not likely to produce drug resistance.

Description

A kind of Synergistic insecticidal compositions and its application containing propargite and cyfluthrin
Technical field
The invention belongs to pesticide fields, and in particular to a kind of using propargite and cyfluthrin as the desinsection of principle active component Composition 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 be 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 at 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.
Cyfluthrin (beta-cyfluthrin), structural formula:
Cyfluthrin is non-internal-absorting insecticide, has and tags and stomach poison function.Nervous system is acted on, fast, length is knocked down Residual effect.Can effectively prevent cotton, fruit tree, vegetables, cereal crop and Lepidoptera on other crops, coleoptera, Semiptera and Homoptera pest can also prevent locust, and can be used as the use of animal health articles for use.
Insecticide variety containing single component often existing defects in pesticide control of insect:Continuous use easy tos produce anti- Pharmacological property, insecticidal spectrum is narrow, and comprehensive protection, peasant's drug cost height etc. cannot be provided for crop.It is various by two kinds or the coming year The combination of active constituent can overcome disadvantages mentioned above to a certain extent to a certain extent.Two kinds or two with synergistic effect Kind or more active constituent combination mixture, preventive effect can be improved, dosage, cost-effective with reducing active ingredient, slows down pest Resistance occurs that simultaneously prevention spectrum can be expanded, and plays that more worms are simultaneous to be controlled, reduces the use cost of peasant.
Invention content
It is an object of the invention to be directed to above-mentioned various problems, in order to overcome and delay the drug resistance to existing pesticide, expand Big mite killing spectrum, reduces drug cost at enhancing drug effect, to provide a kind of prevention various crop Homoptera, Lepidoptera, Acarina worm Harmful Pesticidal combination.
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 cyfluthrin, the Synergistic insecticidal compositions are with propargite and hundred trees Pyrethroids is principle active component, wherein the weight ratio of propargite and cyfluthrin is 1:60~60:1.
The more excellent weight ratio of the Pesticidal combination, wherein propargite and cyfluthrin is 1:50~30:1.Further It is preferred that the weight ratio of propargite and cyfluthrin is 1:20~20:1, the still further preferably weight ratio of propargite and cyfluthrin It is 1:1~10, the most preferably weight ratio of propargite and cyfluthrin is 1:5~10.The weight ratio of propargite and cyfluthrin is also Can be 1:10、1:5、1:10、1:2、1:3、1:1.
The weight ratio of two kinds of shared preparations of active principle accumulation of the Pesticidal combination, wherein propargite and cyfluthrin It is 0.5%~90%, preferably 1~60%.
The Pesticidal combination, using propargite and cyfluthrin as principle active component (active constituent) and auxiliary agent and/ Or excipient is processed into any one dosage form allowed on pesticide.The dosage form that can be processed into is missible oil, suspending agent, aqueous emulsion, micro- Emulsion, pulvis, wettable powder, dispersible oil-suspending agent and water dispersible granules etc..Detergent alkylate may be used in the auxiliary agent Sulfoacid calcium, alkyl phenol polyoxyethylene ether, polyoxyethylene polyoxy propylene block compound (such as agriculture breast 33#), Nonyl pheno Ether etc., excipient include cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propylene glycol), deionized water.The above auxiliary agent, Excipient and other agriculturally known auxiliary materials can be applied alone or be used in combination.
The above-mentioned Synergistic insecticidal compositions containing propargite and cyfluthrin are preparing prevention Lepidoptera, Homoptera, acarian The application of the insecticide of mesh pest.The homoptera pest includes planthopper, and lepidoptera pest includes bollworm, cotten aphid, tiltedly Autographa spp, diamondback moth, Acarina include red spider, tetranychid, Panonychus citri.
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. easy tos produce resistance have good preventive effect;And inhibit pest to single formulation (propargite Or cyfluthrin) drug resistance generate and simultaneously can prevent the pests such as Lepidoptera and homoptera pest.
The Pesticidal combination of the present invention compared with prior art, generates following advantageous effect:(1) compared with single dose, the group Closing object has notable synergistic, control effect to significantly improve the prevention of pest;(2) one medicines more control, a dispenser can simultaneously anti-Zhiduo County Kind pest reduces prevention recruitment cost;By the desinsection prepared containing the Synergistic insecticidal compositions of propargite and cyfluthrin Drug is preventing mite class simultaneously, and can prevent Lepidoptera and homoptera pest, especially has very well to prodenia litura, rice hoppers Preventive effect, achieve the effect that a medicine more control.(3) alternative high-toxic pesticide, and field dosage is greatly reduced, effectively reduce ring Border is polluted and pesticide residue;(4) it has concurrently quick-acting and long-acting;(5) compared with propargite single dose, production and application cost reduces;(6) Pest is inhibited to enhance the resistance of pesticide.
