The investigation was undertaken to test the efficacy of pytoalexin against Fusarium udum, Amongst the eleven concentrations of cajanol tested against F. udum concentrations causing wilt of pigeonpea i.e. 325, 350 and 375 μg/l were found most effective resulting in cent per cent growth inhibition of F. udum. The concentrations of cajanol viz., 350 μg/l and 375 μg/l were found to be most effective against conidial germination of F. udum. Besides the above, a commercial cajanol formulation was also tested against F. udum and the concentrations of 325 μg/l, 350 μg/l and 375 μg/l were againfound to be most effective in inhibiting the conidial growth germination.

The concentrations of cajanol viz., 350 μg/l and 375 μg/l were found to be most effective against conidial germination of F. udum. Besides the above, a commercial cajanol formulation was also tested against F. udum and the concentrations of 325 μg/l, 350 μg/l and 375 μg/l were againfound to be most effective in inhibiting the conidial growth germination.
