Testing Seed Sensitivity and Kinds of Canes

Amorphotheca Aspergillus Chaetomium Fusarium Phoma Pythium Rhizoctonia / / (Aspergillus Chaetomium Macrophomina Mucor Rhizoctonia ) Aspergillus A . fumigatus A. niger Amorphotheca resinae F.solani Ph.betae P.ultimum A. fumigatus M. phaseolina Mucor spp . A. resinae Mucor spp . FD9993 % 54.5 . P. ultimum % 16.66 M. phaseolina % 60.66 .Seed health testing showed the presence of seven fungal genera: Amorphotheca, Aspergillus, Chaetomium, Fusarium, Phoma and Pythium isolated from sugar beet seeds obtained from sugar factory Mosul / Iraq and five genera: Aspergillus, Chaetomium; Macrophomina; Mucor and Rhizoctonia seeds obtained from Alexanderia/Egypt Isolation revealed the presence of two species of Aspergillus (A.fumigatus and A.niger). Amorphotheca resinae, F.solani, Ph.betae and P.ultimum obtained from seeds of Iraq and A.fumigatus, M.phaseolina and Mucor spp. from seeds of Egypt. Amorphotheca resinae and Mucor spp. has been reported for the first time on the sugar beet seeds. During testing, sugar beet sensetivity for fungi isolated from seed of Iraq and Egypt showed that P.ultimum had most pathogenic effect and causing heavy mortilities in different cultivars of sugar beet and the percentage mean of surviving plants 16.66% and M.phaseolina had weak pathogencity (60.66%).
