摘　　要：为筛选出能够防控马铃薯晚疫病且绿色、高效、安全的新型替代药剂,采用田间药效试验法。结果表明,50%烯酰吗啉WP∶60%代森联·吡唑脂WG(1∶1)1320 g a.i./hm^(2)和18.7%烯酰·吡唑脂WG 448.8 g a.i./hm^(2)对马铃薯晚疫病的防控效果达94.88%和92.57%,可每667 m^(2)增产696.64 kg和659.89 kg,增产率达64.29%和60.90%,这说明50%烯酰吗啉WP∶60%代森联·吡唑脂WG(1∶1)和18.7%烯酰·吡唑脂WG可作为替代药剂用于马铃薯晚疫病的大田防控中。In order to screen out a green,efficient and safe alternative medicine which can prevent and control potato late blight,field efficacy test was used.The results showed that 50%phenomorph WP∶60%desenbien·Pyrazole WG(1∶1)1320 g a.i./hm^(2)and 18.7%phenomorph·pyrazole WG 448.8 g a.i./hm^(2)had 94.88%and 92.57%control effects on potato late epidemic disease.It can increase production by 696.64 kg and 659.89 kg per 667 m^(2),with yield increases of 64.29%and 60.90%.50%phenomorph WP∶60%desenbien pyrazole WG(1∶1)and 18.7%phenomorph pyrazole WG can be used as alternative agents for the control of potato late blight in the field.
