Abstract:
Chickpea (Cicer arietinum L.) is the second most important pulse crop after dry beans in tropical, subtropical and temperate regions of the world. Among the different soil borne diseases dry root rot caused by fungal pathogen Macrophomina phaseolina is the most important, devastating and challenging disease of chickpea. An experiment was conducted to test the efficacy of fungicides on radial growth of M. phaseolina which collected during Rabi 2021 from Sangareddy district of Telangana. In this study eight different fungicides were tested at 5 different concentrations under in vitro conditions for their inhibitory effect on test pathogen. Among these fungicides maximum inhibition (100%) on radial growth of M. phaseolina was observed with four fungicides viz. Propiconazole 25% EC, Tebuconazole 60 FS, Mancozeb 63% + Carbendazim 12% WP and Tebuconazole 50% +Trifloxystrobin 25% WG at all concentrations tested and minimum inhibition was observed with Copper oxychloride among all fungicides tested ranging from zero to 24.63 percent with radial growth of 9 cm to 6.78 cm at 1000ppm and 3000ppm concentrations respectively. Whereas remaining fungicides exhibited 81.48 to 91.86 percent inhibition at tested concentrations.
