作者于1996～1997年在河南封丘等四地采用小区和大田试验，就种衣剂包衣玉米种子防治苗期病害及对生长和产量的影响进行研究。用20％克福种衣剂（含10％克百威、10％福美双及微肥、成膜剂等其他助剂80％）包衣处理郑单8、丹玉13、豫玉15、掖单19和掖单20共5个玉米品种种子。结果表明，①能提高出苗率10．43％～40．65％，②对玉米粗缩病及苗枯病防治效果分别为60．00％～86．47％和56．86％～8419％，③使苗期植株高度及鲜重分别增加8．41％～38．70％和4．90％～74．00％，④玉米增产幅度10．00％～29．40％。
In 1996 ~ 1997 in Henan Fengqiu and other four places using plot and field trials, seed coating on the seed coating of seed coating disease control and growth and yield were studied. With 20% KFB seed coating (including 10% carbofuran, 10% thiram and micronutrient, film-forming agent and other additives 80%) coating Zheng Dan 8, Dan Yu 13, Yu Yu 15, tuck Single 19 and Yeda 20 total of 5 varieties of corn seeds. The results showed that: ①the seedling emergence rate was increased from 10.43% to 40.65%; ②the control effect on corn slenderness and seedling blight were 60.00% ~ 86.47% and 56.86% ~ 8419% respectively, ③ so that seedling height and fresh weight increased 8.41% ~ 38.70% and 4.90% ~ 74.00%, ④ corn yield 10.00% ~ 29.40%.
