摘　　要：This study aimed to investigate the effects of Radix Curcumae fungicides on tobacco brown spot and yield of flue-cured tobacco leaves. Through field experi- ments, control efficiency of Radix Curcumae fungicides against tobacco brown spot was investigated. The results showed that the average control efficiency of 400-fold, 600-fold and 800-fold Radix Curcumae fungicides against tobacco brown spot reached 37.83%, 34.09% and 24.32%, respectively. This study could provide the ba- sis for screening and application of plant-derived fungicides against tobacco brown spot.为研究郁金素对烟草赤星病的防治效果及烟草植株的影响,通过大田试验,调查赤星病防治效果。结果表明:郁金素杀菌剂400倍液平均防效为37.83%、郁金素杀菌剂600倍液平均防效为34.09%、郁金素杀菌剂800倍液平均防效为24.32%。该文为烟草赤星病防治的植物源药剂的筛选提供依据。
