Abstract:
The present study was aimed to evaluate the efficacy of biological agents (Trichoderma asperellum and Pseudomonas fluorescens) and a fungicide, Carbendazim (12%) + Mancozeb (63%) application in resisting damping-off disease. The experiment was conducted under pot culture conditions to observe the effects of bioagents and fungicide against P. aphanidermatum. 10 treatments were taken up with 3 replication and data collected were analysed using CRD. The treated seeds were sown in pathogen inoculated soil @10 seeds per pot and irrigated daily. Pots with no pathogen inoculation served as control. The results revealed that seed treatment with fungicide and bioagents against damping-off (Pythium aphanidermatum) as compared to control were significant. Maximum germination was observed in Carbendazim (12%) + Mancozeb (63%) @ 3 g/kg (91%) and among the bioagents T. asperellum @ 4 g/kg (88%) followed by P. fluorescens @ 4 g/kg (86%) as compared to control (56%).
