[0001] The present invention relates to a kind of pesticide. Background technique

[0002] For a long time, with the continuous development and evolution of social production, agricultural production has also shown a state of rapid modernization, but with the passage of time, in agricultural production, crop diseases and insect pests have also shown diversification and multiple occurrences. Due to long-term repeated use of toxic and harmful insecticides (synthetic pesticides), pests have developed strong resistance to pesticides. In order to solve this problem, in actual production, it is often used to increase the use of pesticides to increase the toxicity of pesticides. While solving the damage caused by pests to crops, pesticide residues are inevitably produced in the process of crop production. The continuous accumulation of pesticide residues has caused indelible serious damage to the human body. If this common phenomenon existing in current agricultu...
