| 中文摘要: |
| 针对紫皮石斛锈病。试验选用10%苯醚甲环唑WG,250 g/L嘧菌酯SC,29%吡萘·嘧菌酯SC,75%肟菌·戊唑醇WG 4种杀菌剂进行田间药效试验。结果表明:复配剂29%吡萘·嘧菌酯SC 600 mL/hm2与75%肟菌·戊唑醇WG 300 g/hm2,防效相当且显著高于其余两个施药处理,在第3次施药后7 d时达最高防效分别为87.70%和88.56%,鲜重折合产量比空白对照分别增产13.48%、13.22%,可在实际生产中交替使用。 |
| 英文摘要: |
| 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. |
