Six emulsion concentrates and eleven granular insecticides were evaluated for their ovicidal action against the eggs of red spider mite. Tetranychus cinnabarinus undor laboratory conditions. Granular Insecticides were applied as in- furrow application at two doses of 0.5 and 1 kg a.l./ha and the emulsion concentrates were used as foliar spray and soil drench in three concentrations of 0.025, 0.05 and 0.1 per cent. Phorate and carbofuran granules were the most effective among the seventeen chemicals tested.
