Description

A kind of Pesticidal combination containing o-phenylenediamine insecticides and chlorfenapyr
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing o-phenylenediamine insecticides and chlorfenapyr.
Background technology
The chemical structural formula of o-phenylenediamine insecticides A is as follows:
This insecticide is the new type disinsection immunomodulator compounds that Syngenta Co., Ltd announces, and disclosing its mechanism of action is at present ryanodine receptor agent, without more Experimental report or open, does not also have the site test in composite field open.
Chlorfenapyr, Universal Chinese character name capillary, be succeeded in developing by American Cyanamid Company a kind of new type heterocycle class desinsection, kill mite, nematocide.Chlorfenapyr is a kind of preinsecticide, itself to insect without toxic action.Insect's food-taking or contact chlorfenapyr after in insect bodies, chlorfenapyr changes concrete insecticidal active compound under the effect of mixed-functional oxidase, and its target is the mitochondria in insect bodies cell, make cell synthesize stop vital functions because lacking energy.Different from other insecticide mechanism of action, without cross resistance.Chlorfenapyr is through extensive application in recent years, and insecticidal effect obviously declines.
The insecticide that Long-Time Service is single, insect is easy to develop immunity to drugs, and pesticide dosage is increased, and cause the adverse consequencess such as high poison, consumption are large, residual many, drug effect is poor, and effect field is more single.And research and develop the agricultural chemical compound that seems, then the R&D cycle is long, and screening compounds arrangement works is very numerous and diverse, and non-general research and development institution can bear.But the different mechanism of action and without the insecticide rational mixture by a certain percentage of cross resistance, crop disease prevention effect can be improved, reduce dosage, residual few, reduce environmental pollution, effectively reducing the pesticide resistance of crop, is the study hotspot of current medium and small research and development institution.
