Abstract:
The Fusarium oxysporum f. sp. ciceri was successfully isolated on PDA medium from naturally affected wilted chickpea and proved pathogenic on susceptible cultivar JG-62. Three isolates of Rhizobium spp. viz., Rh1 Rh2 and Rh3 were isolated from chickpea root nodules collected from Latur, Osmanabad and Beed districts on YEMA medium and identified on the basis of biochemical characters. Among three isolates, Rh2 was found most effective in inhibition of mycelial growth of pathogen. Among seven systemic fungicides, Carbendazim was most compatible with Rhizobium spp. (Rh2) and Chlorothalonil and Thiophanate methyl + Pyraclostrobin were found compatible with Rhizobium spp. (Rh2) in contact and combi-product fungicides group. Emamectin Benzoate and Chlorantraniliprole were found compatible insecticides, whereas herbicides Imazethapyr was compatible with Rhizobium spp. (Rh2). Seed treatments of Carbendazim + Emamectin benzoate along Rh2 was superior in recording the least per cent disease incidence in Pot Culture experiment.
