Abstract
The present investigation was conducted to demonstrate and to exploit T. harzianum isolated from local soil by coated seeds to control B. cinerea, the causative agent of brown spot disease in faba bean cv. Minor in greenhouse. Faba bean leaves were collected on 14 days after inoculation. The results showed a pronounced and significant reduction in percent disease incidence. B. cinerea was applied to leaves of pretreated plants, spot area was less appeared (22.3%), and the protection percentage reached about 77.7%. Whereas, the protection percentage did not exceed 18.3% and the spot area was more appeared on non-treated plants (81.7%). Plant length and root extension measurements were enhanced in pretreated plants and inoculated with pathogen.
Keywords: Botrytis cinerea, Trichoderma harzianum, Leaf spot, Faba bean.
