The host plants of greatest importance include rubber, tea, coffee, cacao, grapefruit, orange, nutmeg, mango, apple, coca, and kola.

E. salmonicolor causes girdling cankers which prevent the normal function of some physiological processes, eventually leading to defoliation and die-back of outer branches.

On rubber trees, initial stages of infection appear as drops of latex and silky-white mycelial growth on the bark surface.

In black pepper plants, sterile pink to white pustules approximately 1 mm in diameter appear on young green stems.

In cacao trees, first symptoms of infection usually present as a sparse white mycelium on the bark surface, which can be easily overlooked.

In India, pre- and post-monsoon application of fungicides directly on the trunk and branches of cocoa or rubber trees effectively prevented the disease, while application of a sulphur-lime slurry to tea shrubs worked best in Kalimantan in Borneo, and Validamycin A was found to be the most effective means of control on rubber trees in Vietnam.
