我区有三十多年的植棉历史,棉花害虫成为提高产量和品质的主要障碍之一。为了治虫保产,历年来一直都是采用有机磷、有机氯农药,棉虫抗药性增强,使用浓度越加越大,打药次数越来越多,致使成本增高,污染加重,中毒甚多,严重的影响了棉花生产和人体健康。为解决这个问题,寻找高效低毒低残留农药新品种,我们于1982年进行了20％中西杀灭菊酯(Sumieidin)与当前棉花上使用较好的常规农药的防治对比试验,并结合大田防治示范观察,以测定杀灭菊酯的防虫效果及其增产原因,现将试验结果报导如下:
With over 30 years of cotton-growing history in our area, cotton pests have become one of the major obstacles to improving yields and quality. For insect pest control, over the years has been the use of organic phosphorus, organochlorine pesticides, cotton insects increased resistance, the use of concentration is greater and greater, more and more fight drugs, resulting in increased costs, increased pollution, a lot of poisoning, serious The impact of cotton production and human health. In order to solve this problem and look for new varieties with high efficiency, low toxicity and low residual pesticides, we conducted a comparative control experiment in 1982 on the control of 20% Sumieidin with the conventional pesticides which are used well on current cotton. Combining with field control Demonstration observation, to determine the pest control insecticidal effect and the reasons for the increase, the test results are reported as follows:
