Description

technical field [0001] The invention relates to an environment-friendly pesticide and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Pesticides are used to kill insects, fungi, and other organisms that harm crop growth. The earliest pesticides used were DDT, BCH, etc. They can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and humans, so they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms. In recent years, a batch of high-efficiency and low-toxic pesticides have appeared. Now people have found specific pesticides, that is, hormonal pesticides. Most of the pesticide residues used by people today are harmful to crops. The raw materials of t...
