Abstract: Freshwater? fish, Channa punctatus was exposed to sublethal concentration of a chloroacetanilide herbicide alachlor technical grade and lasso 50% EC for a period of 10 days.? The histopathological changes in the gill include: necrosis, vacuolar degeneration, fusion and atrophy of primary and secondary gill lamellae.? The tissue damages like degeneration of cytoplasm in hepatocytes, atrophy, formation of vacuoles, rupture in blood vessels and disposition of hepatic cords are the histopathological changes observed in the liver.? The changes in the kidney include: necrosis, swelling of renal tubules, cellular hypertrophy and granular cytoplasm.

Key words: Chloroacetanilide herbicide, Alachlor, Lasso 50% EC, Channa punctatus, Gill, Liver, Kidney
