Abstract

Okra or lady’s finger [Abelmoschus esculentus (L.) Moench] which is known as “Bhindi” in Hindi, is one of the most important summer vegetables of Rajasthan as well as India and belongs to the family Malvaceae. This crop suffers severely from the vagary of diseases caused by fungi and important one is root rot incited by Rhizoctonia solani, which is not only reduces the potency of seed, but also degrades the health beneficial and nutritional quality components of the crop. To know the status of disease incidence, a roving survey was conducted during Zaid 2022 in major okra growing districts (viz., Jaipur, Ajmer, Dausa and Tonk) covering Zone III-A of Rajasthan. A total of 48 fields of okra crop were surveyed covering 16 villages in 8 tehsils. Every surveyed field revealed the presence of root rot and it was ranged from 17.00 to 40.74 per cent with all overall mean of 26.71 per cent. The highest mean disease incidence was observed in Jaipur district (31.64%) followed by Tonk (26.69%), Ajmer (24.81%) and lowest was in Dausa district (23.73%). Conclusively, this disease is gaining importance in okra growing areas and may be alarming situation in coming years. Therefore, growers and researchers may take care of, so that it can be managed in time.
