摘　　要：作者用多抗霉素等4种药剂对岳帅苹果霉心病进行防治研究。结果表明,以病情指数统计的防效高于以发病率统计的防效。多抗霉素与扑海因混用在花前1周、盛花期、花期刚结束的幼果期及5月20日左右的幼果期4次用药防治效果最好,防效达到了55.96%。不同用药次数防效的比较表明,盛花期是防治的关键时期。The control efficiencies of four fungicides(Polyoxin,Thiophanate-methyl,Iprodione and Flusilazole)for apple mould core in Yueshuai were investigated in this study. The results showed that the control efficiencies calculated by disease index were higher than calculated by occurrence rate.The mixed application of polyoxin and iprodione sprayed four times(one week befor florescence,full-blown florescence,young fruit period after florescence and young fruit period about May.20th)showed the best control efficiency and it could reach 55.96%.The comparation among different treatments revealed that full-blown florescence was a crucial period for control.
