摘　　要：采用小区试验法进行9%毒死蜱·烯唑醇悬浮种衣剂防治玉米地下害虫和玉米丝黑穗病田间药效试验。结果表明:9%毒死蜱·烯唑醇悬浮种衣剂在药种比为1:50(质量比,下同)和1:60时,对地下害虫的防效分别为86.22%和78.10%,对玉米丝黑穗病的防效为82.51%和74.47%,与对照药剂48%毒死蜱乳油(1:500)拌种、5%烯唑醇干粉种衣剂(1:100)包衣相比差异均不显著;在药种比为1:70时,9%毒死蜱·烯唑醇悬浮种衣剂对地下害虫和玉米丝黑穗病的防效分别为68.45%和57.88%,与对照药剂20%福·克悬浮种衣剂(1:50)包衣相比差异不显著,与对照药剂48%毒死蜱乳油(1:500)拌种、5%烯唑醇干粉种衣剂(1:100)包衣相比差异显著。The field efficacy trials of 9% corn seed coating of chlorpyrifos ＆ diniconazole on hypogenous pests and maize head smut were carried by the method of plot experiment. The result showed that when the proportion of the test pesticide was 1：50 and 1：60, the control effect were respectively 86.22 and 78.10% on hypogenous pests, as well as 82.51 and 74.47% on maize head smut, and has no significant difference with the control pesticides （chlorpyrifos 48% and diniconazole 5%）. When the proportion of the test pesticide and seed was 1：70, the control effect were 68.45% and 57.88%, with significant difference comparing to control pesticides chlorpyrifos 48% and diniconazole 5% and no significant difference comparing to thiram ＆ carbofuran.
