Abstract

The numbers of microflora in the phylloplane of the moderately by susceptible cultivar (Giza 3) were greater than in the resistant entry (ILB 938). About 22% of the bacteria isolated in case of the resistant entry and 6% of those in the phylloplane of the moderately susceptible cultivar were antagonistic to Botrytis fabae. Percentage of inhibition area/plate was higher for fungi from the resistant entry ILB 938 (20.67%) compared with those from the moder­ately susceptible cultivar, Giza 3 (10.11%). It was found that size of the B. fabae spots was reduced as a re­sult of treatment with some isolated antagonistic bacteria (Bacillus spp.) after 2 and 4 days incubation period. However, diameter of the choco­late spots was larger after 6 days compared with the control.
