有效地防治棉花苗期根病和蚜虫是夺取棉花优质高产的首要技术措施。对棉蚜防治始终在有效地进行着,而对根病防治,自有机汞制剂受禁用后,防治面积逐年渐小。棉苗根病给棉花所造成的损失,有时并不低于苗期蚜虫的危害。我们于1978年试制了含有杀菌剂和呋喃丹的复合微粒剂,用它拌棉种的药效试验结果证明,不但能兼治苗期根病和蚜虫,而且对病、虫防治较相应单剂表现了增效作用。
Effective prevention and treatment of cotton seedling root aphids and cotton is the primary technical measures to obtain high quality and high yield. Control of cotton aphid has always been carried out effectively, and prevention and treatment of root and root disease, since the banned of organic mercury preparations, the control area is gradually decreasing. Cotton seedling root cause damage to cotton, and sometimes not less than the damage of seedling aphids. In 1978, we made a trial of a compound microgranule containing fungicides and carbofuran. The results of the efficacy test of the mixed cotton seed proved that it not only can cure both root and aphids at the seedling stage, The synergy.
