Flag smut of wheat caused by Urocystis agropyri (Preuss) A.A. Fisch. Waldh. is an important seed as well as soil borne disease that is now emerging as a serious problem in Himachal Pradesh. During the survey of wheat growing areas of Himachal Pradesh, the highest average incidence of disease (17.77 %) was recorded from Thural of district Kangra followed by Akrot of district Una, Bhager of district Bilaspur and Dhaulakuan of district Sirmour with 14.65, 10.56 and 9.19 per cent incidence, respectively. The overall average disease incidence was significantly higher in 2019-20 (7.12 %) as compared to 2020-21 (5.97 %). The pathogen inoculum buried at 2 cm below the soil surface for 8 months yielded highest spore germination of 18.92 per cent and no spore germination was recorded till 4 months of storage due to the dormancy in any of the screened storage conditions.Keywords
