摘要： 用福美胂40％wp与多菌灵50％wp两种杀菌剂以不同浓度混配及不同时期喷雾防治苹果腐烂病。结果表明：福美胂和多菌灵单独使用时，防治苹果腐烂病作用相当。福美胂高浓度与多菌灵低浓度配合或福美胂低浓度与多菌灵高浓度配合使用时对苹果腐烂病有80%以上的防效。两药剂配合使用的优化方案为福美胂40％wp50～75倍液，多菌灵50％wp100～200倍液；在青海苹果产区,喷药期在3月下旬至4月中旬，防效最佳。

Abstract: 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 .
