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。
