杀菌剂防治马铃薯晚疫病是生产中采用的主要措施。通过施用250 g/L嘧菌酯悬浮剂对河北、甘肃、青海3个地区马铃薯晚疫病的防治效果进行分析。结果表明，250 g/L嘧菌酯悬浮剂对3个地区马铃薯晚疫病均具有较好的防治效果；在河北地区，250 g/L嘧菌酯悬浮剂的有效成分用量为75.00 g/hm2时，对马铃薯晚疫病的防效达到77.53%；在青海地区，各试验处理的防效达到71.26%~84.02%；在甘肃地区防治效果更好，防效均达到80%以上。该试验结果为250 g/L嘧菌酯悬浮剂在生产上的推广使用提供理论依据。

Use of fungicides for control of potato late blight is the main measure adopted in the production of potato. The control efficacy of 250 g/L azoxystrobin SC on potato late blight in Hebei, Gansu, and Qinghai Provinces were analyzed. The results showed that the control efficacy of 250 g/L azoxystrobin SC on potato late blight in Hebei, Gansu and Qinghai Provinces were good. The control efficacy of azoxystrobin SC on potato late blight achieved 77.53%when the amount of effective component of 250 g/L azoxystrobin SC was 75.00 g/ha in Hebei Province. The control efficacies of each treatment achieved from 71.26%to 84.02%in Qinghai Province. Better control efficacy was reached, 80%or more, in Gansu Province. This research provides references for wide application of 250 g/L azoxystrobin SC in production.
