Coffee leaf rust control with cuprous oxide fungicide

摘要

Application of cuprous oxide is effective in controlling coffee leaf rust, considered the main disease of the culture. COPPER FUNGICIDES FIRST used against coffee leaf rust (Hemileia vastatrix) on the Indian sub-continent during the 19th century remain the mainstay for control of this most important disease of coffee, now present in all main coffee growing regions of the world. First report of coffee leaf rust was made in the 1860's by a coffee planter in Ceylon (Sri Lanka). Diseased leaves were sentto England and the causal fungus identified and named by Rev. M.J. Berkley. Biology of the causal fungus and its disease epidemiology was subsequently unveiled in detail by Marshall Ward who also laid basic foundations for future control with protectant fungicides.
