经1979—1982年小区试验,用颗粒剂点施器将3％1605颗粒剂施入玉米、高粱心叶内防治玉米螟获得成功后,1983—1984年被正式列为辽宁省玉米螟综合防治开发试验研究项目之一。两年来累计开发面积16.19万亩。防治玉米螟效果平均为90.14％,兼治玉米蚜虫效果平均为97.81％。据1984年7月试验点调查,兼治二代粘虫效果平均为99.29％,取得了一次施药防治3种害虫的理想效果。 该剂型已于1985年1月在徐州由化工部召开的技术鉴定会上通过,认为是目前国内取代有机氯农药的一个较好剂型。
After 1979-1982 plot test, 3% 1605 granule was applied to corn with particle dot applicator, and corn borer was successfully controlled in corn leaf of sorghum. From 1983 to 1984, it was formally listed as comprehensive prevention and control of corn borer in Liaoning Province One of the pilot research projects. Two years accumulated development area of 16.19 mu. The average effect of preventing and controlling corn borer was 90.14%, and the effect of treating corn aphid was 97.81% on average. According to the survey conducted in July 1984, an average of 99.29% of second-generation armyworm was cured, and an ideal effect of three pesticides for pesticide application was obtained. The dosage form was approved by the technical appraisal meeting held by the Ministry of Chemical Industry in Xuzhou in January 1985. It is considered as a better dosage form to replace organochlorine pesticide in China at present.
