试验证明,用氯丹处理蔗种和蔗田,对防治黑翅土白蚁和家白蚁的效果明显,有效期长达2～3个月以上。但为了获知氯丹处理后,蔗糖中氯丹的残毒问题,1973年我们用氯丹乳液浸渍蔗苗和灌浇蔗田,当年砍收甘蔗榨汁煮糖,并测定其含氯丹的残毒。根据测定结果表明:蔗苗用氯丹稀释100、400倍浸20分钟,或在生长盛期在蔗畦中灌浇乳剂一斤(加水2,000斤/亩),用成熟期收获
Experiments show that the use of chlordane cane and sugarcane treatment, the control of black-winged termites and termites were significantly effective, valid for up to 2 to 3 months or more. However, in order to find out the problem of residual toxicity of chlordane in sucrose after chlordane treatment, in 1973 we used sugarcane emulsion to digest sugarcane seedlings and irrigated cane fields. In the same year, we cut and harvested sugar cane juice and determined the residual toxicity of chlordane. According to the results of the test, the sugarcane plantlets were dipped 100,400 times with chlordane for 20 minutes, or during the vigorous growth period, one kilogram of emulsion was added to the cantaloupe (add water 2,000 kg / mu)
