摘　　要：针对当前生产中糜子丝黑穗病对糜子产量和品质的影响,2018年选用甲基硫菌灵、代森锰锌、百菌清、多菌灵、烯唑醇、噻虫胺等6种药剂,于播种前不同时间段包衣,研究不同药剂拌种对糜子丝黑穗病的防效,初步筛选出甲基硫菌灵、代森锰锌、百菌清、多菌灵4种药剂对黑穗病的防效较好。2019年在此基础上,开展了甲基硫菌灵、代森锰锌、百菌清、多菌灵4种药剂不同药种比的比较试验,结果表明,甲基硫菌灵在3种药种比下,对糜子丝黑穗病的综合防治效果均较好,是首选的拌种药剂;代森锰锌、百菌清、多菌灵在药种比例为1.5%时,综合防治效果也较好。In view of the influence of the head smut on the yield and quality of the millet in the current production,in 2018,six different fungicides(thiophanate methyl,mancozeb,chlorothalonil,carbendazim,diniconazole and thia methoxam)were used to study the control effect of the head smut before sowing and after coating in different periods of time,and four fungicides(thiophanate methyl,mancozeb,chlorothalonil and carbendazim)were preliminarily se lected to prevent the head smut on effect of ear disease was better.On this basis in 2019,by using four different kinds of medicaments,i.e.thiophanate methyl,mancozeb,chlorothalonil and carbendazim,and trying to use different kinds of medicaments ratio.The results showed that thiophanate methyl had better comprehensive prevention effect on smut head smut under the ratio of three kinds of drugs.When the proportion of mancozeb,chlorothalonil,carben dazim is 1.5%,the comprehensive disease prevention effect is also good.
