Weather and plant diseases in Africa :
Information is given on general characteristics of weather and climate in Africa and on humid tropics, sub-humid tropics and semi-arid zone disease complexes. The most common weather elements that influence disease patterns are temperature and humidity. Wind, in addition, plays a major role in disease dissemination. Examples are given of the influence of one or a combination of these factors on the development of a disease. There are effects of temperature and humidity/aridity on cassava bacterial blight disease (Xanthomonas campestris pv. manihotis), of seasonal variations on coffee leaf rust (Hemileia vastatrix), and of drought on severity of charcoal rot (Macrophomina phaseoli) of sorghum. Strategies to minimize the weather impact on crop productivity through its effect on diseases are discussed. (ATA 12(8):59633. 1987)
