The mix fungicide of Asomate 40%wp and Carbendazim 50%wp by different proportion is sprayed at different time in order to control Valsa Mali , the result showed that : the controlling effect is equal while the Asomate 40%wp and Carbendazim 50%wp is sprayed singly , if lower proportion Asomate and higher proportion Carbendazim or higher proportion Asomate and lower proportion Carbendazim are mixed together , the controlling effect over 80% . The optimizing proportion is Asomate 40%wp diluted 50~75 times mixing with Carbendazim 50%wp diluted 100~200 times , in the fruit tree growth area of Qinghai province , the perfect spraying time is last decade of Mar to second decade of April .
