 ABSTRACT

In the present investigation, four efficient Azotobacter isolates viz., AZT-R7, AZT-Y2, AZT-J1 and AZT-G4 were studied for bio efficacy against F. solani using chilli as a test crop under greenhouse condition. In chilli pot culture experiment, these four isolates along with Pseudomonas fluorescens, Bacillus subtilis, Trichoderma and Carbendazim were further tested under greenhouse conditions to assess their antagonistic activity against F. solani. The isolate AZT-R7 recorded significantly less disease incidence of 14.66 per cent followed by Trichoderma sp (22.44 %) and carbendazim (25.12 %) while the plants from control treated with Fusarium solani recorded a significant increase in the disease incidence (38.15 %). AZT-R7 recorded significantly increase in the activity of antioxidants, soluble protein, free phenol contents, increase in the growth and yield parameters and lower total sugar content.
