Abstract:

The tomato crop attacked by early blight, late blight, leaf spots, anthracnose, Dampimg off, buckeye rot, wilts and root rots. Among these Damping off diseases in tomato caused by Rhizoctonia solani is very common to see in nurseries, an increased incidence of blight caused by Rhizoctonia solani was noticed in recent past in major tomato growing areas of Ranga Reddy district of Andhra Pradesh. As Rhizoctonia solani is a soilborne pathogen, the disease caused by it is difficult to manage due to its exceptionally broad host range, soilborne nature and also the long saprophytic survival ability of the pathogen in soil. Keeping the increased incidence of blight on tomato in view, the present study was planned to development of suitable Integrated Disease Management strategy for effective management of disease under pot culture condition. Among the IDM components tested the treatment with potential antagonist (Trichoderma viride) + effective fungicide (pyroclostrobin + metiram) + tolerant cultivar (US 440) showed lowest per cent disease incidenc (18.67) and found superior over the other treatments tried. As the combination of potential antagonist (Trichoderma viride), effective fungicide (pyroclostrobin + metiram) and tolerant cultivar (US 440) resulted in minimum disease incidence when compared to their the individual treatments, the combination treatment in the present study was found to be the most effective IDM strategy in reducing the incidence of R. solani on tomato.


Keywords: Fungicides, Integrated disease management, Rhizosphere isolates, Rhizoctonia solani, Stem blight Tolerant cultivar and Trichoderma.
