Effect of some medicinal plant extracts on controlling chocolate spote disease of faba bean [electronic resource].

Includes reference.

Crude extracts of thym plants (Thymus vulgaris L.) and pepperment plants (Mentha piperita L.) were evaluated as antifungal on the mycelial growth, spore germination and disease severity of Botrytis Fabae Sard, the causal pathogen of chocolate spot disease of faba bean in vitro and in vivo. Three concentrations 25, 50 and 100% were used from the tested plant extracts. Thym plant extracts were more effective than pepperment on inhibiting mycelial growth and spore germination. The efficiency of the tested extracts as antifungal were decreased with dilution. The same trend was found in vivo. Thym plant extract was more effective than that of pepperment plant extracts on reducing disease severity percentages on faba bean. Increasing concentrations of the tested extracts caused significant reduction in disease severity.
