Scopoletin (7-hydroxy-6-methoxy coumarin) which inhibited the conidial germination of Corynespora cassiicola was isolated from the uninfected mature leaves of Hevea brasiliensis. Scopoletin was not detected in uninfected immature rubber leaves. The i

Molecular, physiological and pathological characterization of Corynespora leaf spot fungi from rubber plantations in Sri Lanka

Autor: B. J. Deverall, B. R. Lyon, W. P. K. Silva

Publikováno v: Plant Pathology. 47:267-277

The plant pathogenic fungus Corynespora cassiicola causes a severe leaf spot disease on more than 70 host plant species including Hevea brasiliensis. Genetic variability in 32 isolates of C. cassiicola collected from diverse hosts and locations in Sr

Foot canker and sudden wilt of Hevea brasiliensis associated with Nattrassia mangiferae

Autor: W. P. K. Silva, C. K. Jayasinghe

Publikováno v: Plant Pathology. 43:938-940

An unreported foot canker of Hevea seedlings has been proved to be caused by the fungus Nattrassia mangiferae. Sun-scorch predisposes the seedlings to infection.
