Abstract

usarium oxysporum, F. solani, Sclerotium rolfsii, Rhizoctonia solani and Macrophomina phaseolina were associated with cucumber damping – off disease in the newly reclaimed lands. F. oxysporum however, was the most frequent and constituted 23% of the recovered fungi. All the tested cultivars were susceptible in varied degrees to F. oxysporum. Americana Beta-Alpha cultivar showed the lowest percentage of preand post–emergence damping-off and Denmark BetaAlpha cultivar, recorded the highest percentages. Plant extracts of garlic and onion reduced linear growth of. F. oxysporum, F. solani and S. rolfsii. The highest suppressive effect on F. oxysporum was obtained when garlic extract was added to the medium at 1.5ml/plate. Pre-and postemergence dampingoff were decreased by soaking cucumber seeds in the extracts of garlic or onion at 6% concentration for 60 minutes before sowing. Natural infection by cucumber powdery mildew was decreased by spraying garlic or onion extracts at concentration of 9% and increased of length, fresh and dry weight of shoots and roots as well as number of flowers/plant compared with control. Intercropped cucumber with garlic or onion decreased percentage of preand post-emergence damping–off as well as increased leaves number and number of flowers/plant.
