| Abstract | ||||
| Five different cultivars of watermelon seeds infected with a varied degrees of Fusarium oxysporum f.sp. niveum were treated with biocontrol agents. Pseudomonas fluorescens, Trichoderma berzienum and Chaeiomium globosum at the rate of 1x108 cfu g" and talcum based formulations of (28 x 107 cfug"), (19 X 107 cfug") and (4 x 106 cfuq') at the rate of 6 9 kg" and 10g kg" of seeds were used, respectively. The treated seeds were evaluated for percent reduction of F. oxysporum f.sp. niveum, seed germination, vigour index and field emergence. It was found that P. fluorescens was more effective in reducing F. oxysporum f.sp. niveum infection followed by T. harzianum and C. globosum than vitavax 200 treated and untreated seeds. the formulations of P. fluorescens were effective in reducing F. oxysporum f.sp. niveum infection and also increasing seed germination, vigour index and field emergence, followed by T. harzianum and C. globosum treatments compared to control. | ||||
