Using of the hot water (95-100°C) by Sprinklers system at rate 40 L/m2 and Buried pipes system for 2.0 h in addition to soil solarization were applied to control cucumber root rot disease which caused by R. solani, F. solani S. rolfsii and P. ultimum under commercial greenhouse conditions. Results indicated that complete reduction in total count of all tested fungi was obtained with Buried pipes system with all depths and Sprinklers system with all depths except that depth 21- 30 cm of soil surface with F. solani and P. ultimum fungi . Also, soil solarization was more effective in reducing the pathogens population. On the other hand, the complete protection against root rot disease was obtained with hot water as Buried pipes system for 2.0 h when applied as one or two time and hot water applied as Sprinklers system at rate 40 L/m2 the same results was obtained by Basamid when applied twice. Followed by hot water applied as Sprinklers system (one application) and soil solarization (two applications) it reduced the root rot disease by 85.9 and 90.7%, respectively during the four growing seasons. As for cucumber yield the most effective treatments are hot water applied either Sprinklers or Buried pipes system which increased the fruit yield by 116.4 and 123.4% respectively (one application) and 125.5 and 134.5% (two applications). Also, soil solarization increased the cucumber yield by 96.4 and 109.1% during four growing seasons when applied as one and two applications respectively. It could be suggested that hot water and soil solarization as soil treatments might be safely used commercially for controlling root rot disease of cucumber plants under greenhouse conditions.
