Rhizoctonia bataticola was found associated in most of the fruit samples collected from various parts of northern India. Generally, fungicidal dips are used for its control but poses risk of residues. Biologically safe antifungal chemical like potassium metabisulphite (KMS) was tested against Rhizoctonia bataticola. ED50 and ED90 against the pathogen were estimated to be 3460 and 10100 μg/ml respectively. Relative potency of KMS was about 1000 time lesser than bavistin. Fruit dip in KMS @ 1% solution for 10 min. could check the rot. Washing of fruits reduced rot incidence significantly.
