摘　　要：为了筛选防治芋疫病的高效、安全药剂,于2021年开展了9种杀菌剂的田间防效试验。结果表明,31%噁唑菌酮·氟噻唑吡乙酮悬浮剂药后14、21d病指防效和病叶率防效均为70%以上,持效期长,速效性较差;25%甲霜灵·霜脲氰可湿性粉剂药后7、14 d病指防效和病叶率防效均为70%以上,具有较好的速效性和一定持效性。In order to select the highly effective and safe fungicides against taro leaf blight,the field efficacy trials of 9fungicides were carried out in 2021.The results showed that the control efficacy of famoxadone·oxathiapiprolin 31%SC which based on disease index and disease incidence were both above 70%at 14 days and 21 days after treatment,and it had long effective duration and relatively poor quick-acting property.The control efficacy of metalaxyl·cymoxanil 25%WP which based on disease index and disease incidence were both above 70%at 7 days and 14 days after treatment,and it had good quick-acting property and long effective duration.
