Abstract

Three chemicals (Carbofuran, prophos and phorate) at two concentrations (2 and 4 kg a.i./ha) with two times of applications (7 days before and 7 days after nematode inoculation) were evaluated for their effect on growth of sunflower and development of nematode (Meloidogyne incognita). Among the chemicals tested, phorate at 6 kg a.i./ha applied seven days before nematode inoculation recorded maximum growth of the host plant. However, prophos at 4 kg a.i./ha applied 7 days before nematode inoculation was effective in reducing the nematode development and reproduction.
