Nitrophenol derivatives are known for their harmful insecticidal properties. It is mainly used to control plant pests and diseases. Infected rice plant by rice weevil sitophylus oryzae were taken as sample and effect of various nitrophenol derivatives on soil in different concentration were observed. After insecticidal activity sample were tested and it has been found that in case of water insoluble insecticides, it remains on the surface of sample and affects the user. On the other hand water soluble insecticides don't affect directly sample but insecticide containing water affect useful micro organisms present in soil. It increases soil degradation.
