Problems solved by technology

In recent years, emamectin benzoate preparations have been used to control pests such as rice stem borer, rice stem borer, rice leaf roller, cotton bollworm, etc., have good effects, but the quick-acting effect is slightly poor, and the price of pesticides is relatively low. High, which is one of the factors limiting the widespread use of the drug in my country

Abstract

The invention discloses a pesticide synthesized by cemamectin benzoate and fenitrothion, pertaining to the complex pesticide technical field. The complex pesticide synthesized by the cemamectin benzoate and the fenitrothion comprises 0.1 to 10 weight percent of the cemamectin benzoate and 20 to 50 weight percent of the fenitrothion. The complex pesticide synthesized by the cemamectin benzoate and the fenitrothion of the invention has a co-toxicity factor as high as 186.02 to 261.77, and has good pesticidal effects in combating such resistant pests as chilo suppressalis, yellow rice borer, rice leaf roller, cotton bollworm, small green cicada, with a control rate reaching 96.78 percent. The invention has quick and long persistent effect, little damage to environment and human body and low cost.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular, the invention relates to a compound pesticide of emamectin benzoate and fenitrothion, which is suitable for preventing and treating rice borer, rice borer, and rice borer Leaf borer, cotton bollworm, small green leafhopper and other resistant pests. 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, most of which are mixed...
