Regressional analysis between profile and knowledge level of farmers about climate and weather in relation to crop management

Abstract

Among eight isolates from different districts surveyed, representing different groups of Fusarium oxysporum f.sp. corianderii incited wilt of coriander. Variability was observed in terms of cultural and morphological characters on different agar and broth media. PDA medium was found to be significantly superior and best suited among all media in the present investigations for growth and sporulation of the pathogen. All the isolates produced maximum mycelial growth on potato dextrose agar media followed by Czapek Dox agar media. Both these media were also found better for production of macro and micro-conidia. The Fusarium oxysporum f.sp. Corianderii isolate I2 showed maximum (256.13 mg) mean dry fungal biomass and isolate I6 showed minimum (179.39 mg) mean dry fungal biomass on broth media.
