Abstract

A field experiment was conducted at ICAR-DGR, Junagadh in kharif (rainfed or monsoon season crop) of 2009 and 2010 for integrated disease management (IDM) of major peanut diseases. The IDM component comprised of a combination of seed treatment with Trichoderma, mancozeb, tebuconazole; soil application of Trichoderma and castor cake; and foliar sprays of hexaconazole and tebuconazole. Observations on foliar fungal diseases were recorded by adopting 1-9 modified scale and in the case of soil borne diseases per cent incidence was recorded. The treatments were found effective to maintain the initial plant population and were highest in seed treatment with mancozeb followed by seed treatment with Trichoderma harzianum. Lowest incidence of soil-borne diseases was recorded in seed treatment with mancozeb and seed treatment with tebuconazole in comparison to untreated control. The foliar disease severity was lowest in treatment tebuconazole and two foliar sprays of tebuconazole whereas it was recorded highest in the untreated control. Highest pod and haulm yield were recorded in seed treatment with mancozeb and two sprays of hexaconazole and seed treatment with tebuconazole and two foliar sprays of tebuconazole whereas it was lowest in the untreated control. The cost of treatment are very important to manage diseases, therefore, it is suggested that combination of treatments are most suitable for disease management.
