ABSTRACT
These studies were employed to compare the potential of the nematophagous fungus Lecanicillium muscarium and the chemical nematicides Vydate and Basamid (G) with the fertilizer calcium cyanamide in the control of root knot nematode, Meloidogyne hapla, through soil application under greenhouse conditions. A significant (P=0.05) reduction in the number of galls and egg masses, eggs and juveniles (J2), and the reproduction factor (Rf=Pf/Pi) was observed in the plants treated with L. muscarium compared to the control. However, all chemical nematicides were also effective in reducing the nematode infestation significantly (P=0.05) in soil compared to the control, but there was no significant difference (P=0.05) among them. Plant growth was significantly (P=0.05) improved in the plants treated with L. muscarium.
