Integrated management of Rhizoctonia Root rot disease infecting strawberry in Egypt

Abstract

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.
