种衣剂在棉花、蔬菜、小麦等农作物种子上,经过几年的试验示范结果表明,对防治病虫害、促进幼苗生长、增加产量等方面有显著效果,很受农民欢迎。 1.防治病虫害,提高抗病保苗效果。用种衣剂处理的棉花种子,对苗期的立枯病、炭疽病有较好的防治效果。据金湖、江都县种子公司1991年用种衣剂处理棉花种子的情况看,其发病率2%,比对照发病率5.5%降低近2倍多。1990年泰仓县蔬菜试验站用种衣剂处理小白菜,苗期白粉病发病率2.21%,比对照发病率23.07%降低10多倍。1989年苏州市蔬菜种子公司、徐州市郊区种子站用种衣剂处理的大白菜,其霜霉病发病率32.6%、软腐病19.16%、
Seed coating on cotton, vegetables, wheat and other crop seeds, after several years of pilot demonstration results show that the prevention and control of pests and diseases, promote seedling growth, increase yield and so has a significant effect, very welcomed by farmers. 1. Prevention and control of pests and diseases, improve disease-proof seedling effect. Cotton seeds treated with seed coating, seedling blight, anthracnose have a better control effect. According to Jinhu, Jiangdu County Seed Company in 1991 with seed coating treatment of cotton seed situation, the incidence of 2%, 5.5% lower than the control rate of nearly 2 times. In 1990, Taicang County Vegetable Experiment Station used Chinese cabbage seed coating, the incidence of powdery mildew in seedling stage was 2.21%, which was 10 times lower than the control incidence of 23.07%. In 1989, Suzhou City Vegetable Seed Company and Xuzhou Suburban Seed Station treated Chinese cabbage with downy mildew disease incidence rate of 32.6%, soft rot disease rate of 19.16%
