Coffee Diseases and Pests: Coffee Rust
Coffee rust, or coffee leaf rust, first destroyed
Brazil's crop in 1970. Since the occurance of coffee rust in Brazil, it has spread to every
coffee growing country in the world. Coffee rust and its symptoms were first observed in Sri Lanka in the 1860's. Many countries,
including Sri Lanka and Ethiopia, replaced much of their arabica
coffee with disease resistant robusta coffee. Coffee leaf rust
is spread by wind and rain from spores from lesions on the underside of the
plant (Mitchell,
84).
The rust diesease in coffee is prevented by spraying
with copper-based fungicides at 3-5 kg/ha at 4-6 week intervals
during the rainy season (Mitchell,
85).
