Abstract EN

This study was conducted in Laboratory of Botany, Department of Biology, Faculty of Science/ University of Al-Mergib Al-kums, with the aim of demonstrating the allelopathic effect of the aqueous (cold and hot) fenugreek seed extract (Trigonella foenum-graecum) on the growth and activity of some pathogenic fungi isolated from bean seeds (Vicia faba) and peas (Pisum sativum).

Seven genera of fungi associated with bean and pea seeds were identified using the agar method, and the highest percentage was 95% for Rhizopus sp on untreated pea seeds, while the same fungus reached 50% on seeds treated with5% sodium hypochlorite solution.

It also reached 40% on the bean seeds.

The most frequent fungi: Alternaria alternate, Aspergillus flavus, Aspergillu niger, Fusarium sp, Penicillium sp, Rhizopus sp, and Cladosporium sp Helminthosporium sp, 10 and 20%, respectively, on pea seeds and did not appear on bean seeds, while Alternaria sp.

Bean seeds increased by 15% and did not appear on the pea seeds.

The results obtained in this study also indicate that the fenugreek seed extract has an effect on the rates of fungal colony growth rates, whether this extract is in cold or hot water.

Colony rates of fungi Alternaria alternata, Alternaria sp, Aspergillus niger, Fusarium sp, Rhizopus sp, Penicillium sp were inhibited with concentrations 10, 20 and 30% of fenugreek seed extract (local and Indian) during brooding days
