Mosaic with bright yellowing symptoms suggestive due to bean
yellow mosaic potyvirus (BYMV) was the most frequently found and
likely most damaging virus in faba bean crop. The virus was detected in
different locations in Qalyoubia Governorate using DAS-ELISA.
Enhancements were introduced to Ouchterlony double diffusion test.
Response of some cultivated faba bean cultivars was studied under
artificial inoculation by BYMV. Delaying the sowing date, and spraying
faba bean seedlings with six aqueous botanical extracts under field
conditions fortnightly interval, were achieved as a simple strategy for
BYMV control. Ribosome-inactivating proteins (RIPs) were
demonstrated by protein profile pattern of both faba bean and botanicals
using SDS-PAGE. ELISA was used as a diagnostic tool at the beginning
of the study and at the end to insure no faba virus infections after 3
botanical extract sprayers.
