由于我省玉米长时间连作,农艺性状好但易感丝黑穗病,大面积连年种植造成土壤中丝黑穗病菌积累较多,加上春旱等气候条件影响,丝黑穗病发病率较高,目前对丝黑穗病防治最简便有效的方法就是应用种衣剂进行防治。但不同剂型不同厂家的种衣剂防治效果不同。1998年～2000年三年时间我们承担全国玉米种衣剂包衣协作网试验。同时从省种子总站引进一些国外种衣剂进行试验。结果表明,德国拜耳公司生产的6％立克秀悬浮种衣剂防治丝黑穗病效果好,并且增产幅度大,经济效益高。
Due to prolonged intercropping of maize in our province, agronomic traits are good but susceptible to smut. Large area of successive year planting causes more accumulation of filamentous head smut in soil. Coupled with climatic conditions such as spring drought, the incidence of smut At present, the most convenient and effective way to control head smut is to apply seed coating for prevention and treatment. But different formulations of different manufacturers of seed coating control effect is different. From 1998 to 2000, we undertook the national corn seed coating co-operation test. At the same time from the provincial seed terminus to introduce some foreign seed coating test. The results showed that the 6% Rickettsu suspended seed coating produced by Bayer AG in Germany was effective in controlling head smut and the yield was large and the economic benefit was high.
