Abstract:
The potential synergistic effects of both zinc and ferric sulphate on the nematicidal activity of oxamyl were evaluated in the greenhouse. Tomato seedlings inoculated with Meloidogyne incognita were used to test the fficacy of oxamyl dissolved in water, 0.001% ZnSO4, or 0.002% Fe2 (SO4)3 and applied at various rates. Toxicity of oxamyl toM. incognita increased 11.3 times in combination with Fe2 (SO4)3 and 4.1 times in combination with ZnSO4 compared with toxicity in water alone.
