Plant Disease Research

The present investigation was undertaken to develop an effective and ecofriendly strategy for the management of root rot disease of pea (Pisum sativum L.), which is widely prevalent in moderate to severe form in different parts of the country. It is assuming the status of major disease mainly in south-west zone of Haryana. The diseased plants show poor growth, yellowing and drying of foliage with partially or fully damaged root system. The pathogen associated with this disease was identified as Fusarium solani f.sp. pisi (Jones) Synder and Hansen. Keeping in view the importance of this disease, the study was undertaken to integrate different management strategies likefungicides, phytoextracts, organic amendments and bio-agents. The integration of organic amendment+ seed treatment with fungicide, botanical and bio-agent (Captan 2 gm/ kg seed + Neem oil @ 0.3% + T. harzianum @ 10gm/kg + Mustard cake @ 50gm/sqm) was found superior in minimizing root rot incidence of pea (4.3%) followed by seed treatment with fungicides + botanicals+ bioagent (Captan 2 gm/ kg seed + Neem oil @ 0.3% +T. harzianum @ 10gm/kg) with the disease incidence of 4.7% in comparison to maximum root rot incidence of 14.3 % in the untreated control.
