Abstract

The invention discloses a compound pesticide of quinalphos and hexaflumuron, pertaining to the technical field of compound pesticides. The compound pesticide of the quinalphos and the hexaflumuron comprises hexaflumuron of 0.1 to 10wt percent and quinalphos of 10 to 50wt percent; the best proportion of hexaflumuron to quinalphos is 1: 20 to 40. The co-toxicity coefficient of the compound pesticideof the invention is 126.98 to 340.43, has good effect in control of harmful resistant insects such as chilo suppressaliq, tryporyza incertulas, cnaphalocrocis medinalis, cotton bollworm, smaller green leaf hopper and diamond back moth, etc. with a control rate of 98.56 percent, and good quick lasting effect, little harm to environment and human beings and low use-cost.

Description

technical field [0001] The present invention relates to the technical field of pesticides. Specifically, the present invention relates to a compound pesticide of quinafos and hexaflumuron, which is suitable for preventing and treating rice borer, rice borer, rice leaf roller, cotton bollworm, and small green leaf Resistant pests such as cicadas and diamondback moths. Background technique [0002] Because people use a single dosage of chemical insecticides for a long time, pests are prone to develop resistance. In order to achieve the effect of pest control, they have to use more toxic pesticides or increase the amount of pesticides used, which not only increases the economic burden of farmers, but also pollutes the ecological environment. , destroy the ecological balance, affect the safety of agricultural products, and kill a large number of natural enemies of pests, resulting in more rampant pests. At present, there are a large number of mixed insecticides on the market, m...
