Abstract

Ascochyta blight is the Ethiopia's most important disease of chickpea that affects the quantitative and qualitative chickpea yield. Fungicides management is essential to control this disease. To evaluate the effect of new fungicide management on the ascochyta blight field trial was conducted in 2013 cropping season on randomized complete blocks design with three replications. Factors including: foliar sprays (Top, mancozeb and without spray as control). Statistical analysis showed significant differences among the treatments. The comparison of means showed that application of top fungicide was a suitable strategy for reduction of ascochyta blight severity, incidence and AUDPC as well as the maximum seeds per pod, pods per plant and grain yield recorded on new fungicide. Up to 244.29% marginal rates of return and 14595.5 Birr/ha net benefits were obtained by Top fungicide application. In general, as any other chemical systems, Top fungicide control of ascochyta blight should be regarded as one facet of the integrated control program rather than a method to be used alone.
