摘要
茶饼病是一种茶树上重要的芽叶病害。为了筛选出防治茶饼病的安全有效药剂,选用3种杀菌剂对茶饼病进行了田间药效试验。结果表明:第2次施药后7 d, 10%苯醚甲环唑水分散粒剂40、60 g/667 m^(2)和25%吡唑醚菌酯悬浮剂30、40 mL/667 m^(2)的防效分别为93.48%、93.62%、85.17%、90.18%,而1.5%多抗霉素水剂对茶饼病的总体防效相对较差,所有供试药剂处理均对茶树生长安全。研究表明,10%苯醚甲环唑水分散颗粒剂40~60 g/667 m^(2)和25%吡唑醚菌酯悬浮剂30~40 mL/667 m^(2)对茶饼病具有良好防治效果,建议生产上推广轮换使用。
Tea blister blight,a significant bud-leaf disease of tea tree,poses a threat to tea production.In order to screen out safe and effective fungicides for controlling tea blister blight,field experiments were conducted to evaluate the control effects of three fungicides.The results obtained 7 days after two applications revealed that the control effects of difenoconazole 10%WG at rates of 40 g/mu,60 g/mu and pyraclostrobin 25%SC at rates of 30 mL/mu,40 mL/mu were 93.48%,93.62%,85.17%and 90.18%,respectively.However,50%polyoxin SL provided a poor control against tea blister blight.All the tested agents were found to be safe for tea plant growth.These results showed that difenoconazole 10%WG at 40~60 g/mu and pyraclostrobin 25%SC at 30~40 mL/mu offered effective control on tea blister blight and can be used in rotation during tea production.
