橡胶黑团孢属叶斑病,国内外均有发生。该病为我省垦区橡胶苗圃和成龄树冬梢的主要病害之一。作者通过对病菌的分离培养和试验观察鉴定,初步认为病原菌为 Peri-conia heveae Stevenson and Imle。1980年以来,先后在两个冬季病害流行期,对西双版纳垦区(景洪、大勐龙、打洛)和红河垦区(金平农场)的实生苗圃和大林地中进行调查,对高海拔(1200～1400米)橡胶试种点(勐海、南糯山、大渡岗)病叶也诱发得到该菌。同时对病原菌的生物学特性及其防治等进行了初步研究。现报道如下:
Rubber black spore leaf spot disease, both at home and abroad have occurred. The disease for the reclamation of our province rubber nursery and adult trees one of the main diseases. The author through the isolation and culture of bacteria and experimental observation and identification, preliminary that the pathogen is Peri-conia heveae Stevenson and Imle. Since 1980, surveys have been carried out on the nursery stocking and Dalin sites of Xishuangbanna Reclamation (Jinghong, Dameng Long, Daluo) and Honghe Reclamation (Jinping Farm) 1400 meters) rubber test sites (Menghai, Nannuo Mountain, Dadu Gang) diseased leaves also induced by the bacteria. At the same time, the biological characteristics of pathogens and their prevention and treatment were studied. Reported as follows now:
