Field Control Effects of Three Fungicides on Tea Blister Blight
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.
