Abstract

Evaluation of some grapevine cultivars against the causal fungi of cutting
rots, i.e Fusarium soIani, Fusarium moniliforme, Rhizocton/a so/ani and Botryodiplacfa
theobromae
revealed that Thompsom seedless (Banati), Aame seedless, Early
Superior, Feista and Superior cvs. were the most susceptible to infection with tlle
tested fungi, while Ruby seedless, Cramson, PerteHe, Red Globe and Romi - Red evs
were less susceptible to all the tested fungi. RizolexIT, VrtavaxlT, Topsin M70 and
Moncerin gave good effect against root rot disease.
