毒杀芬是以松节油为主要原料而合成的氯化莰烯混合物。早在五十年代,我国就在浙江、福建、广东等省设厂生产,主要防治棉虫、地下害虫、玉米螟、飞虱、稻苞虫及畜牧害虫。由于在一般情况下,毒杀芬的杀虫效力不如DDT与666,因而销售量逐年下降,产品年有积压。但近年来,不少害虫对DDT与666已发生抗性,实践证明如用毒杀芬与DDT等混用,有显著增效作用。兹将毒杀芬的有效成分及混用后的增效情况介绍如下:
Toxaphene is a mixture of chlorophenols synthesized from turpentine as the main raw material. As early as the fifties, China set up factories in Zhejiang, Fujian and Guangdong provinces to prevent and control cotton insects, underground pests, corn borers, planthoppers, rice worms and animal husbandry pests. Due to the fact that toxins kill pesticides are not as effective as DDT and 666 in general, the sales volume has been declining year by year and the annual product backlog. However, in recent years, many pests have already developed resistance to DDT and 666, and it has been proved that synergistic effects such as mixing with narcotine and DDT have been observed. The active ingredients of toxaphene and the synergistic effect after mixing are hereby introduced as follows:
