| Abstract | ||||
| Physiological and environmental factors have the most important effect on cucumber white mold development. The disease increased with increasing scterotial number in soil. The best method for artificial infection with the pathogen was adding sclerotia to the soil followed by sclerotia + mycelia. but rotled plant wastes caused low infection. Disease incidence was not affected by soil type. Sclerotial inoculation of the pathogen two weeks before planting caused more infected plants than the inoculation at the same time of planting. More apothecia were produced in pots with sclerotia placed at 0-3 cm than those buried deeper. Moreover, using T. harzianum at all tested rates highly reduced mycelial growth and scierotial formation followed by Bacillus spp. No 2 and No 1 at the rate 100%. The commercial bioagent Rizo-N (3 gIL) was the best bioagent preparation followed by Plant-Guard at the same rate. | ||||
