【摘要】 针对玉米生产现状,选择8种高效种衣剂进行防治玉米丝黑穗病的田间药效对比试验。结果表明,不同种衣剂防治玉米丝黑穗病效果差异显著,7.5%黑虫双全和63%福.克.戊种衣剂包衣玉米种子,出苗快,出苗率高,发病率低,防治效果好于其他种衣剂。综合考评种衣剂防治玉米丝黑穗病效果,用含有戊唑醇的种衣剂处理玉米种子比其他种衣剂更为安全。更多还原

【Abstract】 According to the corn production statue,comparison experiment of control effect to 8 different type corn seed coating agents on corn head smut was carried out.The results showed that corn seed coating agents had obviously different control effects on corn head smut.When the seeds were treated with 7.5% Tebuconazole or 63% Thiram.+ Carbofuram.+Tebuconazole coating agents,the coated corn seeds showed quicker germination,higher germination percentage and lower incidence percentage than those treated with the other seed coating agents.So the control effects of these two corn seed coating agents are superior to the others.According to the comprehensive evaluation of control effect of different corn seed coating agents on maize head smut,the corn seed coating agent with tebuconazole is more secure than the others when the corn seeds were treated.更多还原
