摘　　要：为提高烟草黑胫病的防效,确保烤烟正常落黄成熟,达到降本节水增效的目的.2014年-2015年,以 烤烟品种红花大金元为材料,在寻甸、石林和宜良开展80%烯酰吗啉田间小区药剂防效试验.结果表明,80%烯酰吗啉对提高黑胫病的防效、降低防治成本和节约用水效果明显.与目前当地生产上使用的58%甲 霜灵？锰锌相比,防效可提高31.19% ,防治成本下降36. 03% ,节约用水3000kg/hm2.该新药将烟草黑胫 病的防治方式由灌根改为喷雾,不仅提高了防效,还降低了劳动强度.To improve control effect on tobacco black shank disease,ensure normal maturing of flue-cured tobacco leaves,and achieve the goal of reducing production costs,water-saving and increase efficiency in the fields, small plot experiment and verifying test of 80% DMM controlling phytophthora parasitica var. nicotianae were carried out from 2014 to 2015,in Xundian, Shilin and Yiliang. The results showed that the obvious effects were acquired in controlling effect of black shank, reducing control cost and saving water with 80% dimethomorph on tobacco black shank disease. Compared with the dosage of 58% metalaxy-mancozeb on the current production, the control effect increa-ses 31. 19% ; costs decrease 36. 03% and water saving is 3 000 kg per ha. Therefore, the new fungicide of control tobacco black shank dis-ease, after changing the way of root irrigation into spray, not only improves the control effect but also reduces the labor intensity.
