Comparative Efficacy of Trichoderma harzianum and Pseudomonas fluorescens against Meloidogyne incognita and Ralstonia solanacearum Complex in Brinjal

Brinjal plants when treated with biocontrol agents viz., Pseudomonas fluorescens, Trichoderma harzianum, carbofuran 3G, Streptocycline and Neemcake alone significantly reduced the final soil nematode population and wilt disease incidence in brinjal. The highest reduction in final soil nematode population was observed in all the treatments except streptocycline while in case of bacterial population in soil the highest reduction was observed in the treatment with P. fluorescens @15 g/kg of soil.
