The speedily becoming human inhabitants has elevated the dependence on fossil gas established agrochemicals reminiscent of fertilizers and insecticides to provide the mandatory agricultural and forestry items. This has exerted an outstanding strain at the non­ renewable fossil gas assets, which can't final indefinitely. in addition to, indiscriminate use ofpesticides for pests (weeds, bugs, nematodes, pathogens) keep an eye on has led to severe ecological and environmental difficulties viz. , (A) expanding prevalence of resistance in pest organisms to special insecticides. (B) Shift in pests inhabitants, particulary in weeds and bugs. In weeds, species which are extra heavily on the topic of the plants they infest have constructed. In bugs, state of affairs is so much grim, the predators were killed and minor insect pests became significant pests and require very heavy doses ofhighly poisonous pesticides for his or her keep watch over.

(D) poisonous residues of insecticides pollute the surroundings and will end up unsafe to even our destiny generations. (E) a few agricultural commodities may possibly comprise minute amounts ofpesticides residues, with lengthy tenn opposed results on human and cattle wellbeing and fitness. for this reason, severe ecological questions about the reliance on insecticides for pests regulate has been raised. using fertilizers, along with inflicting environmental difficulties has additionally impoverished the soil health and wellbeing and reduced the useful soil fauna. for instance, in a few significant crop rotations viz.
