杀虫剂在木本植物体内传导理论研究进展

杀虫剂通过在植物体内输导而使其通体带药来控制害虫。药剂进入植物体内 ,通过植物蒸腾作用产生的拉力随液流到达作用部位 ,在植物体内呈不均匀分布 ,从而达到控制害虫的目的 ;性质不同的杀虫剂在不同植物体内传导机理不同 ;传导速度与植物生理状态、气候因子、药剂的理化性质等诸因素有关 ;杀虫剂在植物体内的代谢不同于常规施药方法 ,一般在植物代谢旺盛的部位残留量较大 ;通过该技术控制害虫的大量试验表明 ,植物体内注药的方法是行之有效的 ,且对环境的污染显著小于常规施药方法

The review of transmission and translocation of pesticide in wood plant

Pest control by stem injection in wood plant had proved to be an economical,efficient and biorational technology.The suppressed pests action achieved greatly by unequal distribution of pesticide which reached to the target plant tissues followed the plant ascending sap that energy derived from the evaporation tension.Different insecticides may be different type of translocation in wood plant,and the transfer velocity may be affected by many factors such as plant species,climate conditions,the chemical and physical characteristics.The degeneration of insecticide by injection in wood plant was more complexity than tranditional method,obviously,the insecticide quantity of each plant tissues increased by intensive metabolizing,most of all,this technology may be more safe to the environment than conventional means.
