| Popis: | Augmentation of soil with different biological treatments i.e., Trichoderma harzianum cultured on sugar cane bagasse, Trichoderma harzianum (spore suspension 5 × 106 cfu/ml) and plant guard (biocide), successfully controlled Fusarium solani, F. oxysporium and Macrophomina phaseolina, the main pathogens of root rot disease on grapevines in Nobaria province. Complete reduction of these pathogens was recorded at 4 ml/l of plant Guard. Meanwhile, T. harzianum caused a reduction of 80.0, 84.4 and 88.9% of linear growth of the same pathogens respectively. In greenhouse trials, artificially infested soil treated with bio-enhancing bagasse at rate of 10% (w/w) of soil, plant guard 4 g/l and T. harzianum 100 ml/l treatments showed a large effect in decreasing percentages of infection and severity of root rot disease on grapevine seedlings. These treatments caused a reduction in root rot infection caused by M. phaseolina, F. oxysporum and F. solani reach 100, 100, 80% and 80, 60, 60% and 60, 40, 40%, respectively, ... |
