摘　　要：为筛选出对辣椒炭疽病具有较好防效的杀菌剂,选用10种不同杀菌剂于2021年进行田间药效试验。结果表明:3次药后7 d, 32.5%苯醚甲环唑·嘧菌酯悬浮剂、50%咪鲜胺锰盐可湿性粉剂和43%氟吡菌酰胺·肟菌酯悬浮剂的防效分别为85.1%、82.7%和81.9%;25%吡唑醚菌酯乳油、24%烯肟菌胺·苯醚甲环唑悬浮剂和10%苯醚甲环唑水分散粒剂三者的防效在75.8%~77.8%之间;80%甲基硫菌灵水分散粒剂、22.5%啶氧菌酯悬浮剂和25%溴菌腈乳油等处理的防效在69.2%~74.6%之间;50%克菌丹可湿性粉剂的防效相对较差。32.5%苯醚甲环唑·嘧菌酯悬浮剂、50%咪鲜胺锰盐可湿性粉剂及43%氟吡菌酰胺·肟菌酯悬浮剂可作为福建地区防治辣椒炭疽病的较优选择。In order to screen fungicides with good control effect against pepper anthracnose,10 different fungicides were selected for field efficacy trials against pepper anthracnose in 2021.The results showed that 7 d after 3 application,the control effects of 32.5%difenoconazole.azoxystrobin SC,50%prochloraz manganese WP and 43%fluopyram.trifloxystrobin SC were 85.1%,82.7%and 81.9%,respectively.The control effect of 25%pyraclostrobine EC,24%fenaminstrobin.difenoconazole SC and 10%difenoconazole WG ranged from 75.8%to 77.8%,and the control effect of 80%thiophanate-methyl WG,22.5%picoxystrobin SC and 25%bromothalonil EC ranged from 69.2%and 74.6%.However,50%captan WP provided a poor control against pepper anthracnose.32.5%difenoconazole.azoxystrobin SC,50%prochloraz manganese WP and 43%fluopyram.trifloxystrobin SC can be considered as a better option to control pepper anthracnose in Fujian province.
