摘　　要：以9种不同的杀菌剂单剂及其复配剂为材料,探索不同杀菌剂防治杂交水稻制种田稻粒黑粉病的效果。综合2 a试验结果,复配药剂“代森锰锌(711.1 mg/L)+大蒜素(16.7 mg/L)”防治稻粒黑粉病的效果最佳,2020年和2021年的田间防效分别为71.83%~79.36%和60.79%~61.38%,分别高于对照药剂爱苗14.56~33.06和26.41~32.31个百分点,且对种子活力和质量无明显不良影响,可以作为防治稻粒黑粉病的药剂使用。Nine fungicides and their compound agents were used as the materials to explore the effects of different fungicides on the control of rice kernel smut in hybrid rice seed production field.Based on the results of two years of experiment,the compound agent"Mancozeb(711.1 mg/L)+Allicin(16.7 mg/L)"had the best effect on the control of rice kernel smut,with field control effects of 71.83%~79.36%and 60.79%~61.38%,which were 14.56~33.06 and 26.41~32.31 percentage points higher than those of the control fungicide Aimiao,in 2020 and 2021,respectively,and had no obvious adverse effect on seed vigor and quality,so it could be used as a fungicide to control rice kernel smut.
