植物源农药（Botanical Pesticides） China is rich in plant resources, Research and application of botanical pesticides is the earliest country, as early as 1930s on the insecticidal effect of tobacco plants, Derris and pyrethrum, Millettia pachycarpa, Tripterygium wilfordii, Croton, rhododendronmolle, 100 and so on widely. As early as 1980s, this research has entered a new stage of development, and some aspects are approaching and reaching the international advanced level. Especially the research of Meliaceae, with m.toosendan, celastrusangulatus extract of Melia azedarach and ten species of insects were log activity test system, and its chemical composition, mechanism and industrial production have been studied, has obtained the pesticide registration certificate of goods produced a variety of oleic acid and saponin nicotine nicotine soluble emulsion double element alkali agent, saneonin agent, rotenone EC, matrine. Here are some of our achievements in the field of plant derived pesticides: (1) Azadirachtin and azadirachtin The main insecticidal plants of Meliaceae, Melia toosendanin and azadirachtin, neem one of the most prestigious. In recent years, the international Several large companies producing Azadirachtin have been investing in the rapidly growing market for bio pesticides In order to improve the competitiveness of the products, a high quality and high content Azadirachtin insecticide was developed. Such as T in Germany Rifolio M pioneered the extraction and isolation of a powdered concentrate containing 30% Azadirachtin It is formulated as 5% emulsifiable concentrates. In 2004, the Chinese Academy of Sciences Kunming Institute of innovation research group, after years of research And successfully developed neem seeds as raw material, through the steps of degreasing, extraction, separation and extraction of insecticidal active substance master India The preparation process of azadirachtin is obtained. The purity of azadirachtin obtained by this process is more th
