Evaluation effect of bioagents on fusarium wilt of cowpea

The study is focused on the effect of two species of Glomus and Trichoderma in order to control the wilt disease and plant growth of cow pea. In vitro condition, among the bioagents, T. harzianum produced the maximum inhibition zone of 18.20 per cent compared to the minimum of 7.30 per cent by T.viride. Soil application of T. harzianum biomass at 60 g/kg soil in infected soil effectively controlled the Fusarium wilt disease and ultimately improved growth of different characters of plant under glasshouse condition. With regard to observations, results showed maximum plant height of 40.35 cm and fresh shoot weight of 13.20 g in plants treated with pathogen in infected soil using biomass application of T. harzianum.
