New report of Rhizoctonia solani anastomosis group AG-7 associated with root rot disease of black gram in Pakistan

Black gram [Vigna mungo (L.) Hepper] is an important and nutritionally rich pulse crop mainly grown in tropical and subtropical environments. From July to August 2023–2024, black gram plants in Faisalabad, Pakistan, were observed with severe wilting and root rot disease complex symptoms. Following morphological and molecular characterization, the causal pathogen was identified as Rhizoctonia solani anastomosis group AG-7. Based on the present findings and a review of the literature, this is the first report of R. solani as the causal agent of root rot disease in black gram both in Pakistan and worldwide.
