In: Zagazig Journal of agricultural research 2009.v.36(2)Summary: Six fungal biocontrol agents (FBAs) were tested for their efficiency against some cucurbitaceous damping-off pathogens, in vitro and in vivo (under greenhouse condition). The highest infection reduction percetage was realized by the FBA Trichoderma harzianum and Trichoderma koningii. Alternaria alternata, Fusarium solani, Pythium ultimum and Macrophomina phaseolina were more sensitive to FBAs treatment, especially with T. harzianum than the other tested damping-off pathogens, where infection reduction rates were 51.72 to 68%, compared with control. On the other hand, Rhizoctonia solani was the most tolerant among the tested pathogens against the effect of any FBAs applied in vitro and in vivo (infection reduction rate was 28.13% of control).
