Abstract: The effect of salinity levels in irrigation water on recovery of Rhizoctonia solani from tap roots of tomato plants was investigated in two experiments conducted under greenhouse conditions. Potted soil was infested with R. solani and subjected to four salinity levels of 0 (control), 3, 8, and 10-mS cm-1. Recovery of R. solani from segments of tomato tap roots was evaluated. Dry weight of above ground plant parts, fruit number, plant height, and several plant physiological parameters were measured. Response of R. solani to salinity was variable. However, little or no signifi cant differences were found among treatments with respect to all the variables measured.
