Application research of 560 g/L Azoxystrobin & Chlorothalonil SC against Peronophythora litchii

560 g/L Azoxystrobin & Chlorothalonil SC is a new fungicide against Peronophthora litchi. During 2005 and 2006, the result of effect tests in field showed that 560 g/L Azoxystrobin & Chlorothalonil SC used at 1:1 000,1:800 and 1:600 for 3 times gave a control effect of 71.65% to 83.50% in the colour-changing period of fruit, 74.54% to 88.98% in the mature period and 77.01% to 90.54% in the storage period of fruit, significantly better than the control effect of 80% Da sheng WP used at 1:600. 560 g/L Azoxystrobin & Chlorothalonil SC has been registered in the Peronophthora litchii, and it is suggested to be applied in the litchi production in Guangdong and other adjacent provinces.
