[Efecto de los fungicidas de cobre sobre la quema bacterial y la enfermedad de las cerezas en Kenya]

In field trials four different copper formulations, Kocide 101, Perenox, copper oxychloride and Procida Bordeaux Mixture effectively controlled bacterial blight and coffee berry disease and significant increased yields of clean coffee. Under a severe incidence of the two diseases, Kocide 101 sprays were superior in performance. Copper sprays induced phytotoxic symptoms on light soils with low organic matter, but not on heavy, loamy soils. Residual effects of copper sprays in one year increases the susceptibility of trees to infection in the next. Cumulative copper sprays in 2 years had a significant effect on the control of both diseases and on yield response but gave an indication of long-term problems that could arise from excessive use of copper
