Coffee Board of Kenya Monthly Bulletins May 1972

Abstract

Coffee leaf rust was certainly the earliest of the major tropical plant disease to be reported and studied.It has caused enormous financial looses since its occurrence was first reported in Cylon in 1869,and it ultimately caused the abandonment of the coffee industry there.Since then all coffee-growing countries of Asia have suffered and the disease has reached Fiji,Papua,the New Hebrides,and Samoa. In January 1970 the first report of its presence in South America was made,and large acreages in Brazil are affected(Wellma 1970).
