| Fusarium oxysporum. Schlecht. Fusarium solani (Mart) Sacc., Rbizocuuu« so/am K(lhn and Macrophomina p/laseolina ( Tassi) Goid isolated from grapevine plants grown in Beheira. Gharbia and Giza Governorates exhibited wilt and root-rot symptoms. Fusarium spp. were the most common isolated fungi (55.8 "/0) followed by M.phaseolina (26.9%) and R .. so/ani (17.3%). F.oxysporvm was highly pathoqeruc fungus showing root- rot and disease severity of gapevlne Cv. Thompson followed by R.solani and M.phaseolina. The isolated F.oxysporum and R.so/ani were non- pathogenic. Isolation trails from the rhizosphere yielded 17 isolates of bacteria. fungi and actinomycetes . Tncboderme harzianum (No.8), Pencillium so. (No.4), Bacillus subti/is (No. 12) and Pseudomonas fluorescens (No. 10) showed their antagonistic eHect against the isolated pathogenic fungi | ||
