棉铃虫、棉蚜是我省棉花主要害虫,长期以来使用残留高和剧毒农药,极需更新取代,寻找高效、低毒的农药已是当务之急。从1980—1983年我们对新引进的速灭杀丁的杀虫毒理、速度、剂量、残效期以及对棉铃虫、棉蚜卵、幼虫的防治效果进行了研究比较,通过室内外试验和田间示范进行了系统的研究,取得了很好的防治效果和经济效益,受到了生产上的欢迎。下面就速灭杀丁 Cotton bollworm and cotton aphid are the main cotton pests in our province. For a long time, the use of highly residual and highly toxic pesticides is extremely necessary. Therefore, it is imperative to search for efficient and low toxicity pesticides. From 1980 to 1983, we compared the toxicity, speed, dosage, residual period of the newly introduced insecticides and their control effects on the control effect of cotton bollworm, cotton aphid eggs and larvae. Through the laboratory and field experiments Demonstration conducted a systematic study and achieved good control effect and economic benefits, has been welcomed by the production.
