The effect of Pesticide (monocrotophos) was studied on four economically important seaweeds, Ulva lactuca, Caulerpa scalpelliformis, Padina tetrastromatica, and Gracilaria corticata. The seaweeds were cultured in different concentration of monocrotophos mixed sterilized seawater. After 21 days of culture in the laboratory, the algae were harvested for the estimation of various growth and biochemical parameter like daily growth rate (DGR), chlorophyll, carotenoids, protein, carbohydrate, lipid and phycocolloids (agar and algin). In the present study, the brown seaweed Padina tetrastromatica responded well to pesticide by showing enhanced DGR, biochemical content including that of the phycocolloids (Algin). Rest of the seaweeds also responded positively by exhibiting good growth and biochemical increment but to a lesser extent and that too at certain concentrations only.
