辛集市是全国优质棉基地,但棉田黄萎病发生面积却占85%,一般减产15~20%,重病田减产35%以上。部分地块绝收。为减少危害进行了以药剂防治为突破口的试验研究。发现DTM高效杀菌剂,即70%羧酸铜磷铅可湿性粉剂,有内吸双向传导作用,对防治棉花黄萎病有特效。同时确定了最佳药量和配套施用技术,现累计推广87.6万亩次,田间病情指数降低45~74%,亩增皮棉5~18公斤。1994年经河北农大、河北省植保研究所验证。
Xinji City is a national high-quality cotton base, but the incidence of Verticillium wilt in cotton fields accounts for 85%, 15% to 20% in general and more than 35% in severe diseases. Part of the block must not accept. In order to reduce the harm to pharmaceutical control as a breakthrough point of the pilot study. Found DTM efficient fungicide, that is, 70% of copper phosphorus phosphorus lead wettable powder, there are two-way conduction within the role of absorption, the prevention and treatment of cotton Verticillium wilt have special effects. At the same time to determine the best dose and supporting the application of technology, is to promote a total of 876000 acres, the field disease index decreased 45 ~ 74%, mu lint cotton 5 to 18 kg. In 1994 by Hebei Agricultural University, Hebei Institute of Plant Protection verified.
