Problems solved by technology

Traditional pesticides are single-dose, single-dose effect is single, and long-term use leads to continuous improvement of crop resistance, which has a serious impact on the effect of pesticides. Farmers often use increased dosage to maintain the effect, which increases the cost of use and causes damage to the environment.

Abstract

The invention discloses a composite emulsifiable concentrate of clethodim and benazolin ethyl, which includes the components of: (by mass percentage) clethodim 2-20%, benazolin ethyl 10-40%, calcium dodecylbenzenesulfonate 2-8%, pesticide emulsifier 600# 1-2%, and dimethylbenzene 50-70%. The invention also discloses a preparation method of the composite emulsifiable concentrate of clethodim and benazolin ethyl. The method includes mixing the single reagents of clethodim, benazolin ethyl and some packing materials at a certain ratio to form a kind of composite pesticide of clethodim and benazolin ethyl. The composite pesticide is scientifically composited by selective post-emergence herbicides with dyadic absorption and conduction effect, has good preventing and removing effects on broadleaf weeds in rape farmland, and is safe to crops under suggesting dosage.

Description

Technical field [0001] The invention relates to a compound pesticide, in particular to a clethodim and chlorflurazole compound emulsifiable concentrate and a preparation method thereof. Background technique [0002] According to the principle of one drug, multiple treatments, pesticides prepared by a compound preparation method according to a certain mixing ratio are called compound pesticides. Traditional pesticides are single-agent, single-agent effect is single, and long-term use, resulting in the continuous improvement of crop resistance, which has a serious impact on the effect of pesticides. Farmers often increase the dosage to maintain the effect, increase the cost of use, and cause damage to the environment. . Summary of the invention [0003] Object of the invention: The object of the present invention is to solve the deficiencies of the prior art and provide a clethodim and chlorphenirin composite emulsifiable concentrate. [0004] Another object of the present invention...
