四川重庆市自1958年发现甘薯黑斑病为害以来,目前传播蔓延很快,几乎遍及所有公社。据在北碚、南桐等区重点调查,苗期发病一般在10％左右,严重的达40％;窖藏期发病一般在20—25％,严重的达100％。现将我们在四川省科协、农业厅、粮食厅的领导和协作下,与各单位配合,对防治甘薯黑斑病所进行的工作,作一简要报导。 Since the discovery of black spot disease in sweet potato in 1958 in Chongqing, Sichuan, the spread of the disease has spread rapidly to almost all communes. According to the survey in Beibei, Nantong and other areas, the incidence of seedling is generally about 10%, severe up to 40%; celiac disease incidence is generally 20-25%, severe up to 100%. Now, with the leadership and cooperation of Sichuan Association for Science and Technology, Agriculture Department and Food Department, we will make brief reports about the work done to prevent and control sweet spot black leaf disease.
