✦ Synopsis
Five diþ erent cultivars of sorghum seeds infected with a varied degree of Fusarium moniliforme were treated with biocontrol agents. Pure cultures of Pseudomonas ýuorescens, Trichoderma harzianum and Chaetomium globosum at the rate of 1 Â 108 cfu g-1 and talcum based formulations of (28 Â 107 cfu g-1), (19 Â 107 cfu g-1) and (4 Â 106 cfu g-1) at the rate of 6 g kg-1 and 10 g kg-1 of seeds were used, respectively. The treated seeds were evaluated for per cent reduction of F moniliforme, seed germination, vigour index and üeld emergence. It was found that the pure culture of P ýuorescens was more eþ ective in reducing the F moniliforme infection followed by T harzianum and C globosum than the Bavistin treated and untreated seeds. Formulations of P ýuorescens were eþ ective in reducing the F moniliforme infection and also in increasing the seed germination, vigour index and üeld emergence, followed by T harzianum and C globosum treatments in comparison with control.
