Abstract:

Root rot of soybean is an important disease of soybean inflicting heavy losses in crop. The present investigation was carried out to test the efficacy of agrochemicals and fertilizers in vitro. In bioassay test of non systemic fungicides, Zineb 75 WP gave cent per cent inhibition of growth and sclerotial formation at minimum concentration of 500 ppm followed by copper hydroxide 77WP (53.63%). In systemic fungicides, Carbendazim 50 WP proved best with mean inhibition of 97.81 per cent and completely inhibited the growth of pathogen at higher concentration of 500 ppm followed by Thiophanate methyl 70 WP (84.57%) and Tebuconazole 25.9 EC (80.50%). They do not allow sclerotial formation at all concentrations tested. The combinations of fungicides Pyraclostrobin 13.3% WP + Epoxyconazole 5% WP and Metalaxyl 8% + Mancozeb 64% WP gave cent per cent inhibition of mycelial growth and sclerotial formation at all their concentration tested. Among the different herbicides, Quizalophop-p-ethyle 5 EC gave cent per cent inhibition of mycelial growth and sclerotial formation at all concentration followed by the Propaquizafop 10 EC(96.05%), Oxyfluorfen 23.5EC(88.70%) and Oxadiargyl 6EC(82.23%). In in vitro testing of chemical fertilizers, Diammonium Phosphate was quite effective in inhibiting growth and sclerotial formation at all concentration followed by Ammonium Sulphate (72.20%).
