棉田普遍撒施敌敌畏毒土熏杀红铃虫成虫,是防治棉红铃虫的一项重大技术改革。它取代了过去采用的666、DDT 或1605等农药的喷粉、喷雾法,提高了防治效果,使皮棉品级显著提高,且降低了防治成本、减少污染、保护了天敌。这项科研成果获原农业部1981年技术改进一等奖。近年来防治面积已达1,500万亩左右。不少地方还用来防治盲蝽象,麦田粘虫以及稻田后期的褐稻虱等。虽然大面积地施药技术在不断改进,但也存在一些问题,现将敌敌畏毒土防治红铃虫和盲蝽象的方法及注意事项简介如下:
Cotton sprinkle dichlorvos toxic soil generally fumigation adults of pink bollworm is a major technical control cotton bollworm. It replaces the 666, DDT or 1605 and other pesticides used in the past, dusting, spray method to improve the control effect, so that a significant increase in the lint level, and reduce the cost of prevention and control, reduce pollution and protect the natural enemies. This scientific research achievement won the first prize of technological improvement of the Ministry of Agriculture in 1981. In recent years, the control area has reached 15 million mu. In many places, it is also used to control lizards as well as armyworm armyworms and brown planthoppers in the late rice fields. Although large-scale application of pesticide technology in continuous improvement, but there are some problems, now dichlorvos toxic earthworm and red stinkbug bug like the methods and precautions outlined below:
