Temperature, pH, dissolved oxygen and total alkalinity were almost similar throughout the study period and among the treatments (Table 1). Transparency was significantly (p < 0.05) increased
in sumithion high dose and low dose, compared to control. On the other hand, NO3–N and PO4–P concentrations were significantly (p < 0.05) decreased in sumithion high dose and low dose, compared to control (Table 1).
