MICROORGANISMS ASSOCIATED WITH BOLL ROT DISEASES OF COTTON (Gossypium hirsutum)

Abstract

                                Nane species of fungi and one bacterium were found to be associated with the boll rot discase of cotton. Rhizopus stolonifer, Fusarium moniliforme, Trichotheclum sp., F. oxysporum and Aspergillus flavus, were more common. Penicillium sp. and Mucor sp. were not pathogenic. R.stolonifer caused complete boll rotting in five days whereas with Xanthomonas campestries pv. malvacearum boll rotting was competed in 12 days.
