Abstract
Experiments were conducted during the first and the second rainy seasons of 1992 to evaluate efficacy of two fungicides, Benomyl (systemic) and Mancozeb (protectant) for control of false rust (Synchylrium dolichi (Cooke) Gaum) and brown rust (Uromyces vignae Bard) in Uganda. Effect of type of fungicide on disease severity and yield varied with cowpea line and season. In general, Mancozeb was more effective in controlling brown rust than false rust. In contrast, Benomyl was more effective against false rust than brown rust. However, economic gains were achieved only with Mancozeb and only during the second rains when severity of brown rust was high.
