花生云纹斑病,又称花生网斑病,是由半知菌类壳二孢属病菌引起的。在我国沿海地区均有发生,可使花生提早落叶,造成减产20～30%,危害极大。为了防病保产和新技术的推广应用,沈阳化工研究院与新金县植保站协作,筛选出比较理想的药剂代森锰锌,并于1982～1986年进行了应用条件的试验研究,以及在全国组织了多点联合试验示范,现将试验研究结果整理如下。
Peanut cloud leaf spot disease, also known as peanut net blotch disease, is caused by the half-known bacteria Ascochyta sp. In China’s coastal areas have occurred, peanut early leaves, resulting in cut 20 to 30%, a great harm. In order to prevent disease protection and promote the popularization and application of new technologies, Shenyang Chemical Research Institute and Xin Jinxian plant protection station collaboration, screening out the ideal agent mancozeb, and in 1982 to 1986 the application of experimental conditions, and Organized in the country a number of joint pilot demonstration, the test results are summarized below.
