Abstract: The experiment was conducted as a completely randomized design with seven treatments and three replications. The treatments were 10% concentrations of leaf extract. The treated plates were then incubated at 26 °C in the dark. The average diameter of the mycelia growth inhibition zone around the paper discs loaded with each treatment was measured seven days post incubation. The growth inhibition percent was calculated using the formula: IP=c-t/c×100, where IP was the growth inhibition percent, c and t were the diameter of growth inhibition zone in negative control and each of the other treatments. Saraca asoca leaf extract (10.00%), Jatropha curcas leaf extract (10.00%) Lantana camara leaf extract (10.00%), Mentha spicata leaf extract (10.00%), Ocimum sanctum leaf extract (10.00%), Cymbopogon citratus L. leaf extract (10.00%) and Aloe barbadensis Mill. leaf extract (10.00%) leaf extract (10.00%) were tested against Fusarium solani using poison food technique using Potato Dextrose Agar (PDA) which used as basal medium. Both the treatments tested were significantly effective in inhibiting the growth of pathogen over control. Saraca asoca leaf extract (10.00%) showed minimum inhibition percent (39.63%) as compared to Jatropha curcas leaf extract (10.00%) showed maximum inhibition percent (75.93%).
