Abstract

The present invention relates to an insecticide composition which comprises carbosulfan. The insecticide composition is a binary insecticide composition prepared by the mixture of carbosulfan, organophosphorus insecticide, pyrethrin insecticide, insecticide, pyridaben and clofentezine. Synergistic agents are added. The disinsection effect of the insecticide composition is enhanced. Especially, the insecticide composition has high prevention effects for resistance cotton bollworms and diamondback moths. The insecticide composition can be used for preventing and curing injurious insects and injurious acari on crops, such as cotton, vegetables, fruit trees, etc.

Description

The insecticides that contains carbosulfan

The present invention relates to a kind of composition pesticide, is a kind of insecticides that contains carbosulfan specifically.

Carbosulfan (Carbosulfan) is a kind of high-efficiency broad spectrum desinsection, kills mite, nematocide, is the low derivative that poisons of carbofuran, and interior suction is arranged, tags and stomach poison function.This medicament is U.S. FMC Corp. 1980 exploitation, commercialization in 1985, and nineteen ninety, FMC Corp. obtained registration in China, and China began to produce voluntarily in 1994, had now formed the production capacity of producing ton surplus the former medicine 300 per year.But with respect to other pesticide species, output is still very little, trace it to its cause be since to the exploitation of its mixture relatively backward due to.

Before nineteen ninety-five, carbosulfan only occurs with single agent form, mainly is agent of missible oil list and the single agent of seed dressing.Because this medicament price height, its usable floor area and usage amount are also little.Its mixture in 1996 begins to come out, and its consumption and usable floor area are risen to some extent.But its mixture kind seldom, only has only the kind that is mixed with isocarbophos, dicofol, malathion, also do not have substantially with being mixed of other insecticides.Test shows that the above-mentioned effect that is mixed is not remarkable.

The objective of the invention is to propose a kind of carbosulfan composition pesticide and method for making thereof, to enlarge the control spectrum of carbosulfan, reduce its cost of use, delay insect it is developed immunity to drugs, make carbosulfan can serve agricultural production better, for more time.

Below narrate the main contents of invention:
