Integrated management of root rot of gerbera (Gerbera jamesonii H. Bolus ex. J.D. Hook) under polyhouse conditions

An experiment was conducted to manage the incidence of root rot of gerbera (Gerbera jamesonii H. Bolus ex. J.D. Hook) caused by Rhizoctonia solani Kuhn. Under polyhouse conditions through integrated approach. Fungicides and bio-agents were used alone and also integrated with each other against the disease. Trichoderma harzianum alone was found to be more effective than T. viride alone on eintrolling the disease. Integration of carboxin (0.05%) with T. harzianum, carboxin (0.05%) with T. viride and integration of propineb (0.1%) with T. harzianum found to be most effective end dave total control of disease. Though, integration of bioagents with fungicides were found to be superior over individual treatments, fungicides alone viz., benomyl (0.1%), carbendazim (0.1%), iprodione + carbendazim (0.1%) and carboxin (0.1%) also gave cent per cent control of root rot of gerbera.
