DISCUSSION
B. Baya'a
What source of inoculum did you use in your study? Did inocula consist of
isolates from different geographical areas in Syria? Will results be the same if
you utilize plant debris as an inoculum source?
S. Hanounik
They may not be the same, because Ascochyta rabiei has saprophytic activities
and also has been shown to have its sexual phase. These stages in the life cycle
on debris rnay introduce differences in the pathogenicity. It is always better to
use natural inoculumn.
S. Sithanantham
Under dry systems of cultivation, do you visualize foliar sprays with fungicides
as a feasible practice? Many farmers in India prefer to apply insecticides as
dusts rather than as sprays because of the practical difficulties in obtaining
water to apply them.
S. Hanounik
Dusting of fungicides can be adopted one or two times during the season in
areas where water is not available.
H.E. Gridley
Artificial reinuculation has produced more severe infection on a particular
cultivar. Has this been observed naturally in the field?
S. Hanounik
Artificial inoculation with an isolate .taken from severe-type lesions (type 4
lesions) produced more severe infection when artificially applied to the same
resistant genotype. This has been observed in the field very rarely. The presence
of type 4 lesions which are initiated or induced by a natural propagate
