Vascular Diseases of Cotton in Uganda

Abstract

This group of diseases has become much more prevalent in Uganda during the last ten years, though even to-day in many districts they are limited to occasional attacks on individual plants. In other very limited areas they have reached the stage at which some effect on crop production is noticeable, as for instance at the Bukalasa Experiment Station. In Uganda the field officer and the plant breeder must deal with the whole group of diseases as a single entity, as there is no means of distinguishing between the causative organisms concerned in individual cases except isolation in the laboratory. An analysis of what may be termed the "Wilt Complex in Uganda" will be a useful arrangement under which to discuss the work carried out on the diseases and that now in progress.
