Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of using propargite and chlopyrifos as the desinsection group of principle active component
Close object 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.
Chlopyrifos (chlorpyrifos), structural formula：
Chlopyrifos (also known as chlorine pyrazothion, Le Siben, Chlorpyrifos) is acetylcholinesterase inhibitor, belongs to thio phosphorus
Acid esters insecticides.With stomach toxicity, tag, stifling triple role, to a variety of on rice, wheat, cotton, fruit tree, vegetables, tea tree
Chewing type and sucking pest all have favorable effect.Insecticidal spectrum is wide, and the organic matter being easy in soil combines, and is done harm to underground
Worm special efficacy.It is the main replacement pesticide species after China's disabling high-toxic pesticide in 2007, and domestic production scale is big, insecticidal effect
It is good, it is prevention rice grub：The main pesticide species of rice leaf roller, planthopper.
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 insecticidal spectrum, reduces drug cost at enhancing drug effect, to provide a kind of prevention various crop chewing type and sucking mouth parts insect pest
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 chlopyrifos, the Synergistic insecticidal compositions are with propargite and chlopyrifos
For principle active component, wherein the weight ratio of propargite and chlopyrifos is 1:60~60:1.
The more excellent weight ratio of the Pesticidal combination, wherein propargite and chlopyrifos is 1:50~30:1.It is further excellent
It is 1 to select the weight ratio of propargite and chlopyrifos:20~20:1, the still further preferably weight ratio of propargite and chlopyrifos is 1:1
~10, the most preferably 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.
The weight ratio of the shared preparations of the Pesticidal combination, wherein propargite and chlopyrifos two kinds of active principles accumulation is
0.5%~90%, preferably 1~60%.
The Pesticidal combination, using propargite and chlopyrifos 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
Agent, pulvis, wettable powder, dispersible oil-suspending agent and water dispersible granules etc..Detergent alkylate sulphur may be used in the auxiliary agent
Sour calcium, alkyl phenol polyoxyethylene ether, polyoxyethylene polyoxy propylene block compound (such as agriculture breast 33#), nonylphenol polyoxyethylene ether
Include cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propylene glycol), deionized water Deng, excipient.The above auxiliary agent, tax
Shape agent and other agriculturally known auxiliary materials can be applied alone or be used in combination.
The Synergistic insecticidal compositions containing propargite and chlopyrifos can be prepared for preventing rice, wheat, cotton, fruit
Tree, vegetables, on tea tree a variety of chewing types and sucking pest insecticide.
The Synergistic insecticidal compositions containing propargite and chlopyrifos are especially prepared for preventing Acarina, Homoptera, squama wing
Mesh, coleopteran pest insecticide in application, wherein homoptera pest include planthopper, lepidoptera pest include bollworm,
Cotten aphid, mythimna separata, coleopteran pest include wireworm, and acarina pest includes 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 chlopyrifos) drug resistance generate and simultaneously can prevent planthopper etc..
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 insecticide prepared containing propargite and the Synergistic insecticidal compositions of chlopyrifos
Object is preventing mite class simultaneously, and can prevent Lepidoptera, Homoptera, coleopteran pest, especially has very to rice leaf roller, planthopper
Good preventive effect achievees the effect that a medicine is controlled more.(3) alternative high-toxic pesticide, and field dosage is greatly reduced, it effectively reduces
Environmental pollution 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.
