Evaluation of different fungicides and biopesticides under in vitro and in vivo conditions of oyster mushroom (Pleurotus florida Eger) in Chhattisgarh

Abstract

The present investigation entitled “Evaluation of different fungicides and biopesticides under in vitro and in vivo conditions of oyster mushroom (Pleurotus florida Eger) in Chhattisgarh” was undertaken with the objectives to find out the effect of fungicides and biopesticides under in vitro and in vivo conditions on radial growth, inhibition per cent, growth and yield of P. florida. The radial growth of P. florida varied significantly with respect to different fungicides and their concentrations used. Bavistin, subeej and sultaf at 50–75 ppm were highly effective fungicides under in vitro conditions as they did not much inhibit the growth of P. florida. Straw treatment with rilon + formalin (75ppm+500ppm), bavistin+ formalin (75ppm+500ppm) and subeej+ formalin (75ppm+500ppm) were effective under in vivo conditions. The radial growth of Pleurotus florida differed significantly with respect to different biopesticides and their recommended concentration. Minzyme, neem gold and raze were found to be effective under in vitro as well as in vivo conditions.
