Prevalence of mulberry root rot disease in Tamil Nadu

Abstract

The maximum root rot incidence of 55.00 per cent followed by 24.33 per cent were recorded in popular mulberry varieties V1 and MR2 respectively in mulberry growing areas of Tamil Nadu. Among three soil types found in the surveyed area, red soil recorded root rot incidence of 2.33 to 55.00 per cent. Various irrigation methods practiced by the mulberry farmers, drip irrigation recorded the disease prevalence of 0.00 to 37.00 per cent and in channel irrigation it was from 14.66 to 55.00 per cent. Recommended spacing of 3’×3’ recorded minimum root rot incidence (24.33 per cent) followed by 3’×2’ spacing recorded the maximum (55.00 per cent). Age of plantations had a direct relation with occurrence of root rot in mulberry.
