Botanical pesticides are an important component of biopesticides. It refers to the use of stable active ingredients contained in certain parts of plants (roots, stems, leaves, flowers or fruits), and using the recipient plants according to a certain method to protect them from or reduce diseases, insect pests, Plant-derived preparations that are harmful to weeds and other harmful organisms. The plant resources utilized by botanical pesticides are poisonous plants. Therefore, botanical pesticides are also commonly known as “Chinese herbal pesticides”.
Including active ingredients extracted from plants, the plants themselves, and compounds and derivatives synthesized according to the active structure. Categories include phytotoxins, plant endogenous hormones, plant-derived insect hormones, antifeedants, attractants, repellents, sterilizing agents, synergists, plant defensins, isogenetic biomass, etc.
