(D) poisonous residues of insecticides pollute the surroundings and will turn out harmful to even our destiny generations. (E) a few agricultural commodities could include minute amounts ofpesticides residues, with lengthy tenn opposed results on human and cattle health and wellbeing. accordingly, severe ecological questions on the reliance on insecticides for pests regulate has been raised. using fertilizers, along with inflicting environmental difficulties has additionally impoverished the soil wellbeing and fitness and reduced the valuable soil fauna. for instance, in a few significant crop rotations viz.
