试验在田间测定了甲霜灵、甲霜灵+代森锰锌、代森锰锌、霜脲氰+代森锰锌、双炔酰菌胺、恶唑菌酮+霜脲氰、氟啶胺、氰霜唑、霜霉威+氟吡菌胺和中药中提取的苦参碱10种杀菌剂处理对马铃薯晚疫病的防治效果。结果表明：除甲霜灵以外其它9种杀菌剂处理对马铃薯晚疫病均具有显著的防治效果，防治效果最好的是双炔酰菌胺、氰霜唑和霜霉威+氟吡菌胺，其次为氟啶胺、恶唑菌酮+霜脲氰、苦参碱、霜脲氰+代森锰锌、代森锰锌、甲霜灵+代森锰锌。除甲霜灵和苦参碱以外其它处理与对照比较，增产11.11%～45.66%。晚疫病烂薯率为2.94%～12.33%。根据病害发展曲线，病害发展前期使用10种药剂处理，均可达到显著防治效果。病害发展后期，建议选择双炔酰菌胺、氰霜唑和霜霉威+氟吡菌胺进行防治。

Control efficiency of ten fungicide treatments on potato late blight was determined in field experiment. The results showed that there were significant effects on control of potato late blight except Metalaxyl. The best fungicide treatments were Mandipropamid, Cyazofamid and Propamocarb-HCl + fluopicolide, then fol owed by Fluazinam, Famoxadone+cymoxanil, Matrine, Cymoxanil+mancozeb, Mancozeb, and Metalaxyl+mancozeb. Yields were increased from 11.11%to 45.66%as compared with the control. Tuber rotting percentage ranged from 2.94%to 12.33%. According to the disease progress curve, al of the ten fungicide treatments used in the early stage of disease development could achieve a significant control effect, and in the late stage, however, Mandipropamid, Cyazofamid and Propamocarb-HCl+fluopicolide were strongly recommended.
