Effect of Intensity of Root Knot Galling in Seedlings on Yields of Flue Cured Tobacco*

A study was conducted to assess influence of different levels of infection in seedlings on the cured leaf yields. Absolutely healthy and apparently disease-free seedlings showed difference to the extent of 41–46 per cent in green and cured leaf yields. As infection in seedlings increased yield as well as quality of final produce deteriorated further. Results emphasize the need for absolute control of nematodes by fumigation rather than selecting apparently gall-free seedlings from non-fumigated nurseries for planting to ensure maximum yields.
