| Abstract: | Field efficacy trials were conducted to investigate control efficacy of difenoconazole 10% WG, azoxystrobin 250 g/L SC, isopyrazam·azoxystrobin 29% SC and trifloxystrobin·tebuconazole 75% WG against Dendrobium devonianum rust disease. The results showed that control effects of isopyrazam·azoxystrobin 29% SC at 600 mL/hm2 and trifloxystrobin·tebuconazole 75% WG at 300 g/hm2 had better are significantly higher than those of the other two fungicides, with the efficacies of 87.70% and 88.56% 7 days after treatment, respectively, and fresh weight yield increased by 13.48% and 13.22% than the control, respectively. The results indicated that isopyrazam·azoxystrobin 29% SC and trifloxystrobin·tebuconazole 75% WG can be used alternately in practice. |
