棉花苗期,常因立枯病、炭疽病的危害造成烂种、死芽、缺苗、断垄,又因蚜虫的危害造成迟发。1982—1983年,我们使用从美国引进的呋喃丹与多菌灵复配种衣剂处理棉种,收到了既防治病害,又防治虫害的双重效果。具体做法是,按有效成分呋喃丹1—1.1％、多苗灵0.5—0.55％的剂量,拌经过硫酸脱绒的棉种。棉种经种衣剂处理后,发芽率为79.3％,比硫酸脱绒未拌药棉种的发芽率85.3％稍低,与未经任何处理的毛棉种发芽率79.7％ Cotton seedling, often because of blight, anthrax cause rotten seeds, dead buds, lack of seedlings, broken ridge, but also due to the damage caused by aphids late. In 1982-1983, we treated the cottonseed with furadan and carbendazim introduced from the United States, and received the dual effects of both disease control and pest control. The specific approach is, according to the active ingredient carbofuran 1-1.1%, more Miao Ling 0.5-0.55% of the dose, mixed with sulfuric acid through the cashmere cotton species. The seed germination rate was 79.3% after cotton seeds were treated by seed dressing, the germination rate was 85.3% lower than that without sulfuric acid, the germination rate was 79.7%
