Behavior of Hemileia vastatrix during unfavourable weather :
Behaviour of Hemileia vastatrix B. and Br. during the unfavourable cold any dry weather is discussed. On naturally infected as well as artificially inoculated Coffea arabica L. (Kents and S. 795) the rust pustules developed mostly as tiny blisters with necrosed central depression and with negligible or no sporulation in December and January. In April when the weather became warm and humid after the summer rains, the latent pustules sporulated freely, producing uredospores on the older infected leaves, and the disease spread to the new leaves which developed after the summer rains
