Occurrence of severe mosaic disease of potato and study on effect of different treatments under integrated disease management approach
First Online 10-06-2016|
Occurrence of severe mosaic disease of potato caused by Potato virus Y (PVY) in all the potato growing areas of Jorhat district of Assam, India was determined by DAS-ELISA. An integrated disease management experiment for severe mosaic disease was carried out at the Experimental farm of Assam Agricultural University, Jorhat in field condition comprising spraying of commercial neem formulation, application of mineral oil, yellow sticky trap, bio fumigation with rape seed plants one month before planting, bio fumigation with cabbage plants one month before planting, spraying of Metarrhizium anisopliae and spraying of insecticides as treatments. The treatment T4 (bio fumigation with rapeseed plants one month before planting) followed by T2 (four application of mineral oil @ 5 ml/lit at 15 days interval) was found to be most effective in reduction of disease incidences, vector population as well as yield than the other treatments.
