| Abstract | ||
| Three different cultivars of tomato were treated with biocontrol agents. these biological agents were, Pseudomonas fluorescens, Trichoderma harzianum , commercial powder ( Rhizo-N ) containing Bacillus subti/us , commercial liquid ( Plant- Guard ) containing T. harzianum, Rizolex T -60 ,combinations between Rhizo-N , Plant-Guard and P. fluorescens, T. harzianum. The treated seeds were evaluated for seed germination and vigour index. The treated seedling and soil were evaluated for reduction the percentage of Fusarium wilt. It was found that seedling in treatment was more effective in reducing Fusarium wilt than soil treatment. Also, P. flourescens was more effective in increasing seed germination, vigour index and reduction of Fusarium wilt, followed by combination between P. nuorescens, T. harzianum, T. harzianum, Rhizo-N , Plant-Guard and the combination between Rhizo-N , Plant-Guard. Rizolex T -60 treatments was the test effective. | ||
