摘要
疮痂病是马铃薯生产中常见的病害之一,对马铃薯产量和品质的影响较大,近年来安徽马铃薯疮痂病的发生频率呈逐年加重的趋势。通过开展枯草芽孢杆菌、寡雄腐霉、细刹、可杀得及五氯硝基苯等5种药剂对马铃薯疮痂病的防治效果试验,结果表明,枯草芽孢杆菌和寡雄腐霉菌对疮痂病的防治效果较好,防效分别达到51.52%、43.4%。枯草芽孢杆菌处理马铃薯产量最高,为34717.5kg/hm2,比对照增产6.6%,商品薯率达91.3%。
Potato scab is one of the common diseases in potato production,which has a serious impact on potato yield and quality.In recent years,the frequency of potato scab in Anhui was gradually increasing.In this research,we eval⁃uated and compared the effects of 5 kinds of fungicides on potato scab,including Bacillus subtilis,Pythium oligan⁃drum,xicha,copper hydroxide,and quintozene.The results showed that Bacillus subtilis and Pythium oligandrum had better control effects on scab disease,with control effects reaching 51.52%and 43.4%,respectively.The yield of Bacillus subtilis treatment was 34717.5kg/hm2,which was 6.6%higher than the control,and the rate of commercial potatoes reached 91.3%.
