呋喃丹是一种高效、高毒、内吸性很强的广谱性杀虫剂。近年来国内先后在水稻、玉米、棉花、油菜等作物上进行了广泛试验,证明对许多食叶性害虫有很好的防治效果。1980年我们试用3%呋喃丹颗粒剂(美(国产),在棉田进行土层施用,亦表明对棉蚜、棉叶蝉有较好的防治效果。现将试验结果整理如下:一、试验方法1、呋喃丹拌种。试验分五个处理:(1)3%呋喃丹颗粒剂每亩3斤;(2)3%呋喃丹颗粒剂每亩5斤;(3)3%呋喃丹颗粒剂每亩7斤;(4)常规农药(1000倍的甲胺磷,每隔10天左右喷一次);(5)对照(不喷药)。每个小区面积一分。5月1日播 Carbofuran is a highly efficient, highly toxic and highly systemic broad-spectrum insecticide. In recent years, China has carried out extensive tests on crops such as rice, corn, cotton and rape and has proved that it has good control effects on many leaf-feeding pests. In 1980 we tried 3% carbofuran granules (the United States (domestic), in the cotton field soil application, also showed that the cotton aphid, cotton leafhopper have a better control effect now test results are summarized as follows: First, the test method (1) 3 kg of 3% carbofuran granules per mu; (2) 5 kg of 3% carbofuran granules per acre; (3) 3% of carbofuran granules Per acre 7 kg; (4) conventional pesticides (1000 times the methamidophos, spray every 10 days or so); (5) control (no spray)
