  Citrus production in Ethiopia is threatened by a number of biotic and abiotic factors. Among these citrus gummosis is one of the most important biotic constraints in the country. This study was conducted with the objective to measure and estimate the incidence and distribution of citrus gummosis (Phytophthora spp.) in major citrus growing areas of Ethiopia. Surveys were conducted in ten major citrus growing areas of Ethiopia. In each orchard, 30 trees were selected and totally 300 trees were assessed for gummosis incidence. These trees were sampled by making two diagonal transects across the field in the form of an “X”. A tree decline was scored on a 0-4 scale where 0=free of any decline symptom, 4=complete drying of the plant. A tree was defined and recorded as cankered when it had any of the following symptoms: discoloration of the bark surfa.. View More»
