2000~2002年研究明确了红富士套袋果主要果实病害症状为黑点病、褐斑和红晕褐斑病及红点病,分别由粉红单端孢霉(Trichotheciumroseum)、顶孢头孢霉(Cephalosporiumacremonium)和格链孢霉(Alternariamali)侵染所致。筛选出了50%新灵WP、50%多锰锌WP、53%丙森多WP、80%大生M-45WP、50%大敌WP等五种防效优良的药剂,套袋前交替喷施上述药剂800倍液4次,药效达85%以上。
The studies during2001~2002showed that the symptoms of the main disease of culti - var'red fuji'bagged apple were'black spot','brown spot','brown spot around red demitint'and'red spot'respectively caused by Trictothecium roseum Link,Cephalosporium acremonium Corda and Alternaria mali Roberts.Through alternating spraying liquid of800times of Xinling50WP,Duomengxin50WP,Bingsenduo53WP,Dathe-4580WP,Dadi50WP against the bagged apple diseases4times before bagging,the control eff ect s could be above85%.
