Abstract (in English)
Fungal plant pathogens play a significant role in limiting the development of tomatoes. Recognizing the differentiation between pathogenic and non-pathogenic diseases is crucial for effective disease control, as well as for identifying the specific microorganisms responsible for infectious diseases. Among the various diseases affecting tomato plants, foliar diseases are particularly significant production constraints. Fungal foliar diseases such as early blight, septoria leaf spot, and late blight are especially economically impactful. Our study investigated the incidence of fungal diseases on the aerial parts of tomato plants at the research farm of the Faculty of Agriculture, Kabul University, during the growing season. We reported five fungal diseases affecting the aerial parts of tomato plants throughout this period. The identified pathogens included Alternaria, Oidium, Phytophthora, Septoria, and Stemphylium, which were confirmed through visual assessments and laboratory analyses of diseased tomato samples.
