Management of coffee black rot disease caused by Koleroga noxia Donk

摘要

Black rot disease of coffee is the second important disease of coffee. A field experiment was conducted in 2020 and 2021 two seasons to know the efficacy of different fungicides in managing the black rot disease of coffee. A total of eight fungicides were evaluated against the black rot disease of coffee. Results indicated that, out of eight fungicides tested, tebuconazole 50%+ trifloxystrobin 25% w/w WG @ 1g/L was found significantly superior in managing the disease. In both the seasons percent disease reduction was significantly higher in the plants sprayed with tebuconazole 50%+ trifloxystrobin 25% w/w WG @ 1g/L and was on par with the fungicide pyraclostrobin 13.3% + epoxyconazole 5% w/v SE @ 1ml/L followed by tebuconazole 25.6 SC @ 1ml/L when compared to other fungicides and unsprayed control plants. From the present findings, it can be concluded that the fungicides tebuconazole 50%+ trifloxystrobin 25% w/w WG @ 1g/L and pyraclostrobin 13.3% + epoxyconazole 5% w/v SE @ 1ml/L can be used for the effective management of the disease.
