Root rot disease of strawberry caused by Rhizoctinia spp.is a common disease
in commercial fields in Egypt.This study was conducted to identify the pathogen.
Testing four strawberry cultivars for their susceptibility toRhizoctonia root rot disease
and test the efficiency of (bio-control agents, soil mulch, antioxidant, chemical
inducer and fungicides) to control the disease. The obtained data showed that all
tested antagonistic and mulching soil significantly reduces root rot and increased fruit
yield. The severity of infection was reduced when different antioxidant andchemical
inducer were applied to the soil compared with the untreated soil. The combination
between black mulch and fungicides was the best treatment compared to the other
treatments. Integrated control significantly decreased the percentage of infected
plants using (Black mulch+ Boscalid+ Trihoderma hamatum + Salisylic acid)
followed by (Boscalid+ Black mulch) was the most effective treatment in
controllingRhizoctonia root rot disease on cv. Sana strawberry plants.
