Different non systemic and systemic fungicides are tested at four concentrations under in vitro over Macrophomina phaseolina causing charcoal rot of soybean. Among seven non systemic fungicides, mancozeb 75% WP and propineb 70% WP were found to be the most effective fungicides with cent per cent mean mycelial inhibition at all concentrations (1000, 1500, 2000 and 2500 ppm) tested. While, copper hydroxide 77% WP and copper oxychloride 50% WP were found as the least effective with 8.14 and13.09 per cent mean mycelial inhibition, respectively. Among seven systemic fungicides, carbendazim 50% WP was significantly superior over rest of the treatments with mean mycelial growth inhibition of 82.98 per cent at 100, 250, 500 and 1000 ppm concentrations and fosetyl-Al 80% WP was found to be the least effective fungicide among all with the mean mycelial inhibition of 44.58 per cent. The sclerotial formation in all agrochemicals was found negatively correlated with the inhibition of growth.
