    Early blight disease caused by Alternaria species is the most destructive fungal disease of tomato in Ethiopia and in southern Tigray in particular. However, the importance and distribution status of the disease has not been studied in this area. Besides, the reaction of released tomato varieties to the disease was not well documented in Ethiopia. Therefore, the present study was conducted to identify the distribution of early blight in southern Tigray and to evaluate the reaction of some released tomato varieties to the disease under glasshouse conditions. Results revealed that tomato early blight was prevalent up to 89.3% and significantly (p<0.01) varied in disease intensity among the districts and peasant associations of the study areas. Severity of the disease was higher in the Raya Azebo than in the Raya Alamata district with a mean of 42.1% and 25.. Read More»
