Basal rot, white rot and blue mould rot were identified as the major soil-borne diseases affecting garlic fields in Solan, Sirmour and Kullu districts of Himachal Pradesh during the 2019-21 cropping seasons. Diseased samples were collected from the fields and analyzed at the Plant Pathology Laboratory of the university. Data were calculated based on disease incidence. The results of the study revealed that among all the districts namely, Solan, Sirmour and Kullu, the maximum disease incidence was recorded at Lanacheta village of Sirmour district (29.96 %) and minimum was observed in Nauni village of Solan district (2.11 %). Moreover, the highest overall disease incidence (14.71 %) was recorded in 2019 and the lowest (3.38 %) in 2020. Among the three soil-borne diseases, basal rot exhibited the highest incidence, followed by white rot and blue mould rot. Furthermore, it was observed that Sirmour district was significantly more affected by these diseases, in terms of incidence, than the other two districts. These soil-borne diseases pose a serious threat to garlic production and farmer income, underscoring the need for effective management strategies.
