ABSTRACT: Extracts and exudates of seeds and roots of plant play a role in plant
health and attracted the pathogen to the host. This study was conducted the
effect of extract and exudates from bean seeds and roots on fungal growth of Botrytis
cinerea, Macrophomina phaseolina and Rhizoctonia solani.
Chemical analysis of extract and exudates was also studied. Seed and root
extracts and exudates obtained from Libyan cv. gave the most stimulating effect
on the mycelia growth of all tested fungi in a descending order, than those extracted
and exuded from seeds and roots of the Giza-6 cv. In vitro chemical analysis
of seed and root extracts and exudates of both cultivars indicated that total
amino acids were much higher in Libyan cv. than those in Giza-6 cv., while free
and total phenol contents were much greater in the seed and root extracts and
exudates of Giza-6 cv. compared with those from Libyan cv.
