Abstract
The invention discloses a complex pesticide of fipronil and padan derivation, which belongs to the field of composite pesticide technology. The complex micro-emulsion of fipronil and padan derivation comprises 0.1-1 percent by weight of the fipronil and 10-15 percent by weight of the padan derivation. Co-toxicity coefficient of the composite micro-emulsion of fipronil and padan derivation of the invention is 139-171. The invention has a good controlling effect on resistant insects such as chilo simplex, yellow rice borer, rice leaf roller, rice thrips, diamondback moth, cabbage caterpillar, beet armyworm, American leaf miner, soybean-pod-borer, corn borer, smaller green leafhopper, etc. with a controlling rate of 95.49 percent; The invention also has a good rapid and durable effect and has little harm to environment and human beings with a low using cost.
Description
technical field [0001] The present invention relates to the technical field of pesticides, in particular, the present invention relates to a method for preventing and treating stem borer, stem borer, rice leaf roller, rice thrips, diamondback moth, cabbage caterpillar, beet armyworm, American spot Mixed insecticides for resistant pests such as flies, bean pod borers, corn borers, and green leafhoppers. 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...
