马铃薯贮藏病害药剂筛选试验

Selection of Chemicals for Potato Storage Diseases

经过多年对马铃薯贮藏期间病害调查,发现有环腐病、软腐病等细菌性病害和晚疫病、湿腐病、干腐病、坏疽病等真菌性病害。其中主要危害马铃薯贮藏的病害是干腐病,其次是晚疫病和环腐病;耐病性和品种也有关系,晋薯24号和大同里外黄品种较耐贮藏,晋薯16号和冀张薯12号耐贮性差。通过药剂防治比较试验得出:80%络合态代森锰锌防治干腐病和晚疫病病害效果分别达45.17%、81.80%,其次是二氧化氯防腐保鲜剂防治效果分别达58.35%、58.77%,是贮藏期较适宜的病害防治药剂。

In this paper, the diseases of potato during storage were investigated, and bacterial and fungal diseases were found. The main diseases of potato storage are dry rot, followed by late blight and ring rot. Jinshu 24 and Datong Liwaihuang were more resistant to storage than Jinshu 16 and Jizhangshu 12. The results showed that 80% complex mancozeb had 45.17% and 81.80% control effects on dry rot and late blight respectively, followed by 58.35% and 58.77%control effects of chlorine dioxide preservative respectively, which were suitable for Disease Control in storage period.
