在斯里兰卡,三叶橡胶容(?)感染三种具有重要经济影响的叶病.这三种病是由炭疽刺盘孢菌引起的橡胶炭疽病菌(Colletotrichum glocosporicides Pens.)橡胶白粉病菌(Odiums heveae Steinm.)以及疫霉菌(Phytophthora meadit)所引起的.对这三种病原菌的生物学曾经进行过详细研究(Wimalajeewa,1965;1967;Peries,1964;1965;1966;Peries和Fernando,1966)斯里兰卡橡胶研究所自1962年以来对三叶橡胶叶病流行规律进行了研究.本文对这个问题所得到的资料作了评价并认为气候在三叶橡胶叶流行病的发展中的重要性与防治病害的经济情况.
In Sri Lanka, cloverleaf (?) Infects three leaf-borne diseases of major economic importance: Colletotrichum glocosporicides Pens. Odiums heveae Steinm .), And Phytophthora meadit. The biology of these three pathogens has been studied in detail (Wimalajeewa, 1965; 1967; Peries, 1964; 1965; 1966; Peries and Fernando, 1966) The prevalence of Clover rubber leaf disease has been studied since 1962. This paper evaluates the information obtained on this issue and considers the importance of climate in the development of the Clover leaf leaf epidemic and the economics of disease control .
