三氯杀螨砜对若螨和螨卵高效,可以破坏成螨的生殖机能,残效期较长,但是不能杀成螨,剂型只有可湿性粉剂,悬浮率低,为弥补其缺点,我们用能提高悬浮率和展布力的人工合成洗衣粉与之混用,收到了较理想的效果。1984年6月16日在西充县义兴乡19村二组用1∶1的20％三氯杀螨砜可湿剂与合成洗衣粉,加水500倍防治柑桔红、黄蜘蛛,与单用20％三氯杀螨砜500倍液作对比,每个处理各喷3株广柑树,施药前
Tetracycline against mite and mite eggs and high efficiency, can destroy the reproductive function of adult mites, long residual period, but can not kill into mites, formulations are only wettable powders, suspension rate is low, to make up for its shortcomings, we use energy Synthetic laundry detergent to improve the suspension rate and spread of the mix with it, received a more satisfactory results. June 16, 1984 in Xixi County, Yixing Township, 19 villages in the second group with 1: 1 20% tetracalline sulfa wet chemical agents and synthetic detergent, add water 500 times to prevent citrus red, yellow spider, and single With 20% dicofol sulfone 500 times for comparison, each treatment spray 3 Kwong tree, before spraying
