近年来,棉田使用呋喃丹微(颗)粒剂拌种或沟施对保证棉花生产起了重要作用,深受棉农欢迎。唯因药源不足,目前仍不能满足棉花生产的需要。为了解决药源不足的问题,寻求治蚜效果好的农药新品种,1981年国内首先由天津市农药工业研究所合成新杀虫剂涕灭威。并由黄砂作载体加工成了20～40目的涕灭威颗粒剂。1981年冬季,我们利用天津市农药工业研究所提供的涕灭威样品,在温室内初步测定了涕灭威对棉花的有效安全使用剂量和防蚜效果。1982年天津市农药工业研究所又将经过改进的涕灭威颗粒剂提供给我们进行田间防治棉蚜药效试验,现仅将田间试验所获结果初报如下:
In recent years, the use of furosemide micro (particles) cotton seed dressing or ditch to play an important role in ensuring cotton production, welcomed by cotton farmers. However, due to lack of medicine, it still can not meet the needs of cotton production. In order to solve the problem of lack of medicine and seek new pesticides with good aphid control effect, in 1981, the domestic first synthesized pesticide aldicarb from Tianjin Pesticide Industry Research Institute. And from yellow sand for processing into a 20 to 40 mesh aldicarb Granules. In the winter of 1981, we used aldicarb samples from Tianjin Pesticide Industry Research Institute to determine the effective and safe dosage of aldicarb to cotton and the anti-aphid effect in the greenhouse. 1982 Tianjin Institute of Pesticide Industry in turn aldicarb Granules improved to provide us with a field aphids efficacy test, now only the results of field trials reported as follows:
