农业植保
专门应用于植物源生物农药的活性成分
根据活性成分的种类，植物源生物农药（Plant Extracts Biopesticides）可大体分类为：生物碱类、挥发油（植物精油）类、光活化毒素类、黄酮类和萜烯类等。其中萜烯类天然成分一般在植物精油中含量最高，根据成分结构差异，进一步分为倍半萜烯、单萜、双萜和三萜。
萜烯类化合物可利用植物挥发物等活性物质成分，根据拒食、胃毒等作用机理干扰靶标昆虫的生殖、生理行为，从而起到植保的运用。可用作生物农药母药中的活性成分，开发拒食剂、引诱剂、趋避剂、除草剂等绿色生物农药。这类新农药具有无有害残留物、不污染土壤和水源，不毒害人体和动物等优势。且具备更强的IPM抗性管理能力，相比较传统化学农药，结构更复杂，靶标昆虫不易产生抗药性。
除此外，由于活性成分天然取源自植物本身，因此还具有增效功能，可起到植物增效剂、植物生长调节剂的功效。
乙酸肉桂酯是由肉桂醇与乙酸缩合而成的乙酸酯。 存在于肉桂叶油中。 它具有香味、代谢物和杀虫剂的作用。 它来源于肉桂醇。乙酸肉桂酯也是肉桂油的一种成分。 Terpineol is naturally found in pine oil, lavender oil, orange leaf oil, neroli oil and other plant oils. Geraniol is naturally found in more than 200 kinds of essential oils, including geranium oil ,Citronella oil, East-Indian geranium oil and rose oil, etc. Citral natural is a mixture of two geometric isomers,geranial (trans confirmation) and neral (cis confirmation).It is obtained by the vacuum distillation process of the lemon grass oil or litsea cubeba oil. Natural Anethole is mainly used as flavor in food, pharmaceutical, fragrance and industrial uses. Alpha- thujene is terpene fraction distilled from Eucalyptus. It appears colorless to pale yellow liquid with woody, green odor. 2-Phenylethanol is an antimicrobial, antiseptic, and disinfectant that is used also as an aromatic essence and preservative in pharmaceutics and perfumery.
