杀虫剂对柑桔叶表皮穿透性的研究

INVESTIGATIONS ON THE PENETRATION OFINSECTICIDES INTO THE CUTICLE OF CITRUS LEAF

摘要: 采用杀虫剂残留量分析法研究了烟碱和氰戊菊酯对柑桔叶表皮的穿透性及叶片气孔、表面活性剂、温度等因素对其穿透率的影响。结果表明，二种杀虫剂由于理化性上的差异其穿透性能不同，而叶片气孔、表面活性剂、温度等对其穿透作用有一定的促进影响。

Abstract: The penetration of fenvalerate and nicotine into the cuticule of citrus leafwas studied by using the insecticide residue analytical technique. It was foundout that the penetrating capability of two selected insecticides differed due tothe variation in their physicochemical natures.The results also showed that thestomal density, addition of surfactants and temperature had positive effect onthe penetration process.
