Plant-derived pesticides are pesticides whose active ingredients are derived from plant bodies. Botanical pesticides have the advantages of being environmentally friendly, generally low in toxicity, and resistant to pests and diseases in the control of crop diseases and insect pests. They are the preferred pesticide varieties for the production of pollution-free agricultural products. In order to enable farmers and agricultural extension workers to have a comprehensive and profound understanding of plant-derived pesticides, the main plant-derived pesticide varieties developed in China and their application in crop pest control are summarized below for reference. .
