摘　　要：为筛选出防治黑龙江省甜菜主产区甜菜褐斑病效果较好的杀菌剂,采用田间小区试验方法,使用杜邦福星、异菌脲、苯醚甲环唑、代森锰锌、甲基托布津、阿米西达、凯润等7种杀菌剂,在3个时期对甜菜品种SD13829进行叶面喷施。通过对褐斑病发病情况调查及块根产量和含糖比较得出:喷施3次供试7种杀菌剂后最终防效达27.61%～68.26%,提高产量4.85%～15.28%,含糖率增加0.63%～7.73%,产糖量增加5.74%～24.20%。其中杜邦福星、苯醚甲环唑处理对甜菜褐斑病防治效果最好,防治效果分别为60.73%和68.26%,产量增加15.28%和13.14%,含糖率增加7.73%和5.99%,产糖量增加24.20%和19.91%,推荐其在生产中使用。To select better fungicide for the control of sugar beet cercospora spot, the experiment which was done in one of the main production area in Heilongjiang Province, Hailun City was taken the method of field pots and was used Nustar, Iprodione, Difenoconazole, Mancozeb, Thiophanate-methyl, Azoxystrobin, Pyraclost robine to foliar spray for SD13829 at three stages. Through the survey of prevalence situation and the comparison between production and sugar content, the result showed the last control effects can achieve 27.61%-68.26%, the seven fungicides increased the yield 4.85%-15.28%, increased the sugar yield rate 5.74%-24.20% and sugar content 0.63%-7.73% after spraying fungicides three times. Nustar and Difenoconazole had the better control effects for bactericide. The effects were 60.73% and 68.26%, the yield increased 15.28% and 13.14%, the sugar yield rate increased 7.73% and 5.99%, sugar production increased 24.20% and 19.91%.They could be used in the production.
