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