Abstract:
Rice sheath rot caused by Sarocladium oryzae is an emerging fungal disease, spreading over rice-growing areas in Union Territory of Jammu and Kashmir. Extensive roving surveys were undertaken during Kharif seasons of 2019 and 2020 to determine the status and distribution of the disease in major rice-growing districts Jammu division in viz., Jammu, Samba, Kathua, Rajouri and Udhampur as location-specific surveillance. The disease was widespread in all the locations in varying proportions during both the years. The percent disease index (PDI) varied from 15.83-38.71 and 15.67-37.00 per cent with overall mean of 27.93 and 26.48 per cent during the Kharif seasons 2019 and 2020, respectively. However, pooled data of both the years revealed that the mean PDI ranged between 15.75-37.86 per cent. The highest overall mean PDI of 34.53 per cent was recorded in district Jammu followed by 31.59, 28.58, and 23.17 per cent in Udhampur, Rajouri and Kathua districts, respectively and it was minimum i.e. 18.15 per cent in the district of Samba. The mean PDI was higher during Kharif 2019 (27.93%) than in Kharif 2020 (26.48%).
