Abstract
Turfgrasses play an important role in improving the environment atmosphere, and functional values in modern cities. Soil-borne diseases are one of the most significant constraints to ornamental nursery outputs. Among several fungi isolated from the roots of turfgrass plants collectedfrom different land scape gardens located at Alexandria , Cairo, and Giza, Rhizoctoniasolani, Fusariumsemitectum,and Fusariumoxysporumwere the most aggressive soil-borne isolates against both Bermuda andseashore Paspalumcvs. Other fungi were isolated from the same areas included, Helminthosporium sp < /span>., Pythiumspp.(fungi like), Alternariasp.,and Macrophominaspp.Essential oils and elicitors, were investigated in vitro at three concentrations for their antifungal activities against the growth of these fungi. These agents as well as the fungicide Topsin-M 70%, for a comparison,were evaluated in a greenhouse for their efficacy in controlling root-rot diseases on both Bermudaandseashore Paspalumcvs.. They were also evaluated for their effect on the plant contents of phenols and chlorophyll. It was found that Bio-Arc®at a concentration of 6 gl-1 was the most effective one among all treatments tested for suppressing the linear growth of F. oxysporum and M. phaseolina, while clove oil was the most effective growth inhibitor against F. semitectum, the fungus like P. splendens, and R. solani. For the greenhouse experiment, the most effective treatment in reducingroot-rot disease incidence wasTopsin-M followed by clove oil and Bio-Arc®. For the biochemical tests inturfgrasses, all tested treatments increased the phenols and chlorophyll compared with the untreated control. From the results, it is noted that the Bermuda grasscv. is more resistant to root-rot diseases than the seashore Paspalumcv.
