Evaluation of hot water treatment on seed germination and seedling infection of artificially inoculated cowpea seeds by Xanthomonas axonopodis pv. Vignicola

Author(s): Nandini R., Shripad Kulkarni*

Abstract

Cowpea [Vigna unguiculata (L.) Walp.] is an important multipurpose pulse crop subjected to various diseases, among them bacterial blight is one of the important diseases caused by Xanthomonas axonopodis pv. vignicola (Burkh. 1944) Vauterin et al., 1995. Which is known to cause severe reduction in grain yield as it is both internally and externally seed borne pathogen. The investigation was undertaken at UAS Dharwad to study the effect of hot water treatment on disease and pathogen to mitigate the problem effectively. Hot water treatment by both roll paper towel method and pot culture experiment revealed that 520C for 10 min., was found effective in eliminating seed borne bacteria Xanthomonas axonopodis pv. vignicola without affecting seed germination to a greater extent.
