Do not use insecticides on water intended for drinking by humans or animals. Use all materials with care to avoid hazards to fish and wildlife. Granular formulations are more suitable for penetrating heavy vegetative cover than solution or ernulsion concentrates. Higher doses are necessary in highly polluted water and by residual and prehatch treatment .
