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。
Tetrahydrolinalool is colorless clear liquid.It has more pleasant floral odor than linalool. Terpineol is naturally found in pine oil, lavender oil, orange leaf oil, neroli oil and other plant oils. Natural Camphor is a waxy white or transparent solid with a distinct strong aromatic fragrance 肉桂醛天然存在于肉桂油、肉桂油和广藿香油中。 呈淡黄色粘稠液体,带有肉桂和辛辣气味。 肉桂醛有顺式异构体和反式异构体。 肉桂醛在工业上由苯甲醛和乙醛在稀碱溶液中缩合制得。肉桂醛广泛用于日化产品和农业的香精香料配方。 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. p-Menthane-3,8-diol, also known as para-menthane-3,8-diol, PMD, or menthoglycol. Mainly used as insect repellents, especially natural culicifuge 伞花烃是一种具芳香性的单萜,存在于多种天然精油中。可由三氯化钌与α-水芹烯反应制备。也可通过樟脑与五氧化二磷反应并用酸碱纯化得到。呈无色液体,不溶于水,可与乙醇和乙醚混溶。 Carvone mainly used for the preparation of peppermint flavor of food and fragrance formulation of daily chemicals.
