Varieties and functions of botanical pesticides

Botanical pesticides refer to pesticides whose active ingredients are derived from plants. Plant-derived pesticides have the advantages of being environmentally friendly, generally low in toxicity, and not easy to produce resistance to pests in the prevention and control of crop diseases and insect pests. They are the pesticide varieties that should be preferred for the production of pollution-free agricultural products. In order to enhance everyone's understanding, the main botanical pesticide varieties developed in my country and their application in the prevention and control of crop diseases and insect pests are summarized and introduced as follows for your reference.
