Abstract:

An intensive roving survey was undertaken in major tobacco growing districts of Karnataka viz., Mysuru, Hassan, Shivamogga and Davanagere to know the extent of root-knot nematode infestation. Results revealed that the disease was widespread in all the tobacco growing regions of Karnataka with an average root-knot index of 2.90. Maximum root-knot incidence was noticed in Harave village of Hunsur taluk, Mysuru district with nematode population of 756.00 J2/200 cc soil and 356.00 J2/5 g of root. Whereas, least incidence of root-knot infestation was observed in Kattige village of Davanagere district, with nematode population of 120.00 J2/200 cc soil and 105.00 J2/5 g of root.
