1997年在辽宁省的3个地区进行了3种种衣剂防治玉米病虫害的田间小区试验．结果表明，质量分数为17％呋喃丹+多菌灵种衣剂以1：50重量比包衣对玉米安全，可有效防治玉米苗期病害和地下害虫，平均防效分别达68．91％和71.35％，适宜在辽宁北部地区使用．质量分数为17％克百威+多菌灵+三唑酮种衣剂对玉米丝黑穗病有良好的防治效果，平均防效为54．26％，适宜在辽宁中部和南部地区推广．
In 1997, three kinds of seed coating agents were used to control corn pests and diseases in three districts of Liaoning Province. The results showed that the 17% furadan + carbendazim seed coating was safe for maize by coating at 1:50 weight ratio, which could effectively prevent maize seedling disease and underground pests. The average control effect reached 68.91% and 71.35%, suitable for use in northern Liaoning. The mass fraction of 17% carbofuran + carbendazim + triadimefon had good control effects on corn smut, the average control effect was 54.26%, which was suitable for popularization in central and southern Liaoning.
