采用菌丝生长速率法比较6种杀菌剂对蓝莓枝干溃疡病病菌(Botryosphaeria dothidea)的抑制作用。综合各药剂不同稀释倍数处理的抑菌表现,药剂抑制菌丝生长作用由高到低为吡唑嘧菌酯>苯甲·丙环唑>咯菌腈>腈苯唑>氟啶胺>嘧菌酯;抑制中浓度以吡唑嘧菌酯最低,为0.008 1 mg/L。
The mycelial growth rate method was used to compare the inhibitory effects of six fungicides on blueberry dry-botulopa dothidea. According to the antibacterial performance of different agents in different dilution times, the inhibitory effect of the agents on mycelium growth was pyrazole azoxystrobin> benzopiroxazole> fludioxonil> trimethoprim> fluazinam> azoxystrobin Ester; the lowest concentration of pyrazole azoxystrobin was inhibited at a concentration of 0.008 1 mg / L.
