In vitro Efficacy of Fungicides against Dry Root Rot (Macrophomina phaseolina) of Soybean

Abstract

Chemical control is one of the measures to manage the disease and avoid the losses. The evaluation study was therefore conducted in vitro. Ten fungicides were tested against the pathogen i.e. Macrophomina phaseolina in vitro. The highest inhibition (100%) of M. phaseolina was observed due to carbendazim 50% WP at different concentration (250, 500, 1000 ppm), mancozeb 75% WP (1500, 2000, 2500 ppm), ridomil-MZ 72% WP (1000, 1500, 2000 ppm) and carbendazim 12% + mancozeb 63% (1500, 2000, 2500 ppm) followed by propiconazole at 250 ppm (87.21 %), 500 ppm (89.92 %) and 1000 ppm (92.64 %) and rest of the treatments significantly inhibited colony growth over control.
