MANAGEMENT OF ROOT-KNOT DISEASE OF BRINJAL CAUSED BY Meloidogyne spp.

Abstract

A field experiment was conducted for the management of root-knot of brinjal with nematicides Furadan 5G (@ 12g1plot), neem product neembicidin (@ 5 mIlL water), and organic. soil amendment poultry refuse (@ 2 kg/plot) either singly or in different combination. It was observed that application of the treatments neembicidin, poultry refuse and combination of Furadan 5G combined with poultry refuse reduced root-knot nematods population, gall index and improved plant growth of brinjal. Among the treatments poultry refuse combined with Furadan 5G appeared to be the best. Neembicidin and poultry refuse individually did not cause satisfactory improvement of plant growth. Significantly higher yield (1.5 t/ha) was found under the treatment T4 (Furadan and poultry r.efuse). But the treatment T4 resulted statistically similar effect to that of treatment T7 (Furadan 5G, poultry refuse, neembicidin) in reducing gall and increasing yield of brinjal over control. By correlation and regression study it has been found that the galling incidence hampered the crop growth in terms of shoot and root length along with fresh and dry root weight.
