Abstract

The Brinjal (Solanum melongena L) is a common and popular vegetable crop grown extensively in Assam and major source of income for the small and marginal farmers of the state. The major constraint in the production of brinjal is the bacterial wilt disease caused by Ralstonia solanacearum. It constitutes a serious obstacle to the cultivation of brinjal, causing total damage of plantations before(15-23% loss) as well as after bearing fruits(54.6- 62.5%). Biological control through the use of natural antagonistic microorganisms has emerged as one of best eco friendly management system, a promising alternatives to chemical pesticide. Local strain of biocontrol agents were tested for finding out the best bio-agent in suppressing the attack of Ralstonia solanacearum on Brinjal under field condition. Among all tested combination, the treatment containing combination of Trichoderma viride + Pseudomonas fluorescens applied in Seed+ Root + Soil methods of application was found most effective in reducing the incidence(19.80%) of bacterial wilt disease under field situation. Highest per plant yield , (3866.77 g/plant) , plant height, fruit size (337.02 gram per fruit) and numbers were also recorded from the same combination and the same methods of application.
