摘要
研究在苹果花露红期和落花60%~70%时喷施4种生物药剂防治苹果霉心病的效果。结果表明,10%多抗霉素可湿性粉剂、3%中生菌素可湿性粉剂、10%宁南霉素可溶性粉剂和6%春雷霉素可湿性粉剂4种生物药剂对苹果霉心病的防治效果分别为88.10%、85.54%、76.30%和70.41%,花朵坐果率分别为93.67%、96.33%、84.67%和85.67%;化学药剂40%苯醚甲环唑悬浮剂对苹果霉心病的防治效果为91.10%,但花朵坐果率仅为63.33%。综合比较,10%多抗霉素可湿性粉剂和3%中生菌素可湿性粉剂较好,建议在生产上推广应用。
The control effects of four biological fungicides to apple mould core were studied in this paper during the red bud period and 60%~70%flowers fallen.The results showed the control effects of 10%Polyoxin WP,3%Zhongsheng mycin WP,10%Ningnan mycin SP and 6%Kasuga mycin WP against the apple mould core were 88.10%,85.54%,76.30%and 70.41%,respectively.And the fruit setting rate were 93.67%,96.33%,84.67%,and 85.67%for these four biological fungicides.On the contrary,the control effects of 40%Difenoconazole SC against the apple mould core was 91.10%.However,the fruit setting rate was 63.33%.Therefore,10%Polyoxin WP and 3%Zhongsheng mycin WP could be used to contol the apple mould core in application.
