Coffee Wilt Disease (Plate 1C), G. xylarioides (F. xylarioides) Coffee Wilt Disease (tracheomycosis) is a vascular disease caused by the fungal pathogen, G. xylarioides (F. xylarioides) and results in a total death of the infected coffee trees.

Substantial losses on several estates in the Solai Valley have been incurred from a bacterial dieback characterized by angular, black necrotic lesions on leaves and blackened internodes.

However, despite the growth, the billions worth of khat that leave Kenya each year have had little impact on the farmers’ standards of living, especially Meru, Kerio Valley, and Embu regions where most of the product is grown.The bulk of proceeds from miraa ends up in the pockets of middle men made up of Kenyans and Somalis who export the product to Somalia or Britain. Breeding for resistance against CLR in Arabica coffee has successfully utilized single or combinations of major genes designated as SH genes. Affected pants fruits will fail to ripen fully and after ripening they produce light beans which have a sour taste. Coffee Research Station, PO Box 4, Ruiru, Kenya. Providing your crops with adequate nutrients improves the health of the crops they require to resist diseases in comparison to the use of fungicides. In a review of their own research the authors summarize incidences and distributions of the most important fungal diseases in Ethiopia and progress in breeding for resistance. Pests, diseases, and fungi have become a real threat for many producers. Copyright © 2010 Production and hosting by Elsevier B.V. https://doi.org/10.1016/j.jare.2010.08.006.
