Efficacy of bio-agents as root dip treatment against root-knot nematode, M. incognita on brinjal

To find out the eco-friendly and economically feasible method for management of root-knot nematode, M. incognita infecting brinjal through fungal and bacterial bio-agents as root dip treatment were tested. Root dip treatment was done with T. harzianum, T. viride and P. fluorescens at two doses viz., 5 g, and 10 g per litre water and the chemical check carbosulfan 25 EC at 2 per cent were used. Results revealed that T. harzianum at 10 g per litre water was the best treatment as compared with T. viride at 10 g per litre water and P. fluorescens at 10 g per litre water in improving plant growth as well as in reducing nematode population over other treatment.
