Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a crop pesticide and a preparation process thereof. Background technique [0002] my country is rich in crop resources and various in variety. For a long time, my country has always adopted chemical pesticide spraying and poisoning to the pest control of crops. Due to the long-term and irrational use of chemical pesticides, it is easy to cause pests to develop resistance, and these chemical pesticides remain for a long time, are difficult to degrade, and endanger people's food safety. There is an urgent need for a green insecticide that is efficient in insecticide, easy to decompose without residue, and non-toxic to crops. For this reason, we have proposed a kind of crop insecticide and its preparation process. Contents of the invention [0003] The present invention proposes a crop insecticide and its preparation process to solve the problems raised in the bac...
