摘要
以倍硫磷为对照,研究了分别用聚乙烯醇和水作稀释剂时丙硫磷在松针上的消解动态,结果表明:丙硫磷和倍硫磷一样,同属于消解速率较慢的有机磷杀虫剂;用0.5%聚乙烯醇作稀释剂的丙硫磷在使用初期有较强的耐雨水冲刷能力,能延长药剂持效期,减少环境污染。
This paper reports the degredation tendency of prothiofos on pine needles as compared with Fenthion. Both Prothiofos and Fenthion belong to the kind of organic phosphoros insecticides with relative lower rate of tendency. The prothiofos diluted with 0. 5% polyvinyl alcohol is able to improve its stickness, prolong the effective periods of insecticides and reduce environmental pollution.
