Description

A kind of Pesticidal combination containing flufenoxuron and chlorine fluorine cyanogen insect amide
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Pesticidal combination containing flufenoxuron and chlorine fluorine cyanogen insect amide.
Background technology
The resistance problem of pest is global problems.Along with Chemical Control of Harmful Insects continuity, the increase of Pesticide use amount and not scientifical use agricultural chemicals, pest resistance is day by day serious, and the pest species producing resistance is on the increase.Particularly to the Lepidoptera class pest that agricultural production is caused harm serious, resistance level is higher, and resistance development speed is relatively very fast.Meanwhile, the use agricultural chemicals of high strength, causes Practice for Pesticide Residue in Agricultural Products to exceed standard, environmental pollution and the increase of peasant's drug cost etc., is unfavorable for agricultural sustainable development.Therefore, the pesticide of efficient, the low toxicity of research and development, environmental protection has positive effect to agricultural sustainable development.
Flufenoxuron (flufenoxuron) act as suppression chitin synthesis to insect, better to the effect of immature mite and insect.Flufenoxuron is mainly used in preventing and treating the insect on the fruit tree such as apple, oranges and tangerines and the plant such as vegetables, cotton, harmful mite, all has good control efficiency to insects such as spider mite kind, rust mite class (rust mite), leaf miner, diamond-back moth, cabbage caterpillar, cotton bollworm, heart-eating worm class, nocturnal moth class and locustamigratorias.
Chlorine fluorine cyanogen insect amide is the novel pesticide that Zhejiang Provincial Chemical Engineering Research Inst is developed voluntarily, code name ZJ4042, and chemical name is: the chloro-N of 3- 1-(2-methyl-4-sevoflurane isopropyl base)-N 2-(1-methyl isophthalic acid-cyano ethyl) phthalic amide, shown in structural formula following (I):
This insecticide belongs to Novel ortho benzenedicarboxamide insecticides, by activating calcium release channel in blue Buddhist nun's alkali recipient cell, causing the runaway release of storing calcium ion, is the compounds acting on blue Buddhist nun's alkali (Ryanodine) acceptor of insect cell few in number at present.Wide spectrum preventive effect is had to lepidoptera pest.
When flufenoxuron and chlorine fluorine cyanogen insect amide are used alone, drug cost is higher, limits it to a certain extent and applies, and is used alone for a long time and easily causes pest resistance degree constantly to increase.Therefore, flufenoxuron and chlorine fluorine cyanogen insect amide being carried out mixture, is a kind of effective ways preventing and treating agriculture resistant insect.
