近年来,甲胺磷乳油已广泛应用于防治稻、棉害虫。但由于其对人畜有高毒,使用或保管不当,容易发生中毒事故。为了降低甲胺磷对人、畜的毒性,摸索发展甲胺磷的新加工剂型,以满足防治农作物害虫的需要。1983年我们在江苏省农林厅植保处的领导下,由江苏丹阳建山农药厂提供2％甲胺磷粉剂农药,分别对防治稻纵卷叶螟用量、用药适期,以及稻飞虱的防治效果作了试验。现将结果初报如下:
In recent years, methamidophos EC has been widely used to control rice, cotton pests. However, due to its high toxicity to humans and animals, the use or improper storage, prone to poisoning. In order to reduce the toxicity of methamidophos to human beings and livestock, a new processing formulation of methamidophos was explored to meet the needs of preventing and controlling crop pests. In 1983, under the leadership of the Plant Protection Department of Agriculture and Forestry Department of Jiangsu Province, we provided 2% methamidophos pesticide from Jiangsu Danyang Jianshan Pesticide Factory to prevent and control rice leaf roller, its proper period and prevention and cure of rice planthopper The effect was tested. The results are as follows:
