Abstract:- Herbicides are toxic molecules. They primarily affect the plant cells but studies have shown that they are equally toxic to animal cells. In the present paper, studies on the histopathological effects of these herbicides on different regions of guinea pig’s alimenting canal were made after administering proper LD50 dosages. The study revealed shrinking of the cells and enlargement in intervilli space in the duodenum of the animal. The study also shows that herbicides cause wide range of effects on the animal tissue including histopathological changes.
