Abstract
To assess in vitro evaluation of bio-efficacy different three biochar's viz., Green house waste (GHW), Eucalyptus wood (EW) and Citrus wood (CW) were evaluated at different three concentrations (each @ 1, 2 and 3%) against F. oxysporum f.sp. radicis-cucumerinum causing root and stem rot of cucumber by using poison food technique. Among the three different biochars, Green house waste (GHW) was found most effective by showing minimum mycelial growth of 50.78, 40.10 and 29.88 mm and 43.58, 55.44 and 66.80% per cent growth inhibition at 1, 2 and 3% concentrations, Whereas, Citrus wood (CW) depicted highest mycelial growth 66.26, 55.88, 44.30 mm with 26.38, 37.91 and 50.78% lowest per cent growth inhibition of the pathogen at same above concentrations, respectively.
