Survey, Incidence and Pathogenicity of Root Rot Disease of Cotton in Different Districts of Haryana Incited by Rhizoctonia spp

Aim: Survey, incidence and pathogenicity of root rot disease of cotton in different districts of Haryana incited by Rhizoctonia spp.

Design: Survey.

Place and Duration of Study: Ten major cotton growing districts in Haryana during Kharif 2021 and Kharif 2022.

Methodology: A roving survey to record cotton root rot incidence was conducted in ten major cotton growing districts of Haryana during the month of June and July for consecutive two Kharif seasons 2021 and 2022. On an average 4 growing region of cotton in each district were visited and percent disease incidence was recorded.

Results: Among all the surveyed districts of Haryana the maximum mean disease incidence was recorded in Fatehabad (18.75%) followed by Hisar (15.25 %), Sirsa (15%), While the minimum disease incidence was recorded in Nuh and Charkhi dadri 9.25 per cent in both during kharif 2021. Among all the surveyed districts of Haryana the maximum mean disease incidence was recorded in Fatehabad (18.25%) followed by Sirsa (15.25%), Hisar (15.42%), While the minimum disease incidence was recorded Charkhi dadri (9.08%).

Conclusion: The results of the current study showed that important cotton-growing regions in Haryana have root rot disease incidence. It is clear from the overall study that root rot disease is common in significant mulberry-growing regions in Haryana. As a result, resistant cotton types are urgently needed to address the grower's issue, together with the best management techniques, such as effective biocontrol agents that can significantly reduce the illness. Consequently, research should be conducted to ascertain the incidence of the disease in different places.
