The speedily turning out to be human inhabitants has elevated the dependence on fossil gasoline dependent agrochemicals comparable to fertilizers and insecticides to provide the mandatory agricultural and forestry items. This has exerted a very good strain at the non­ renewable fossil gasoline assets, which can't final indefinitely. along with, indiscriminate use ofpesticides for pests (weeds, bugs, nematodes, pathogens) regulate has ended in severe ecological and environmental difficulties viz. , (A) expanding prevalence of resistance in pest organisms to big insecticides. (B) Shift in pests inhabitants, particulary in weeds and bugs. In weeds, species which are extra heavily concerning the vegetation they infest have built. In bugs, state of affairs is such a lot 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. (C) better environmental pollutants and overall healthiness dangers (a) rather from illness of floor and underground consuming water assets and (b) from their inhalation in the course of dealing with and alertness. (D) poisonous residues of insecticides pollute the surroundings and will end up detrimental to even our destiny generations. (E) a few agricultural commodities may perhaps include minute amounts ofpesticides residues, with lengthy tenn antagonistic results on human and farm animals wellbeing and fitness. as a result, severe ecological questions on the reliance on insecticides for pests keep watch over has been raised. using fertilizers, along with inflicting environmental difficulties has additionally impoverished the soil future health and lowered the valuable soil fauna. for instance, in a few significant crop rotations viz.

Example text

This increasing awareness, in recent years, has led to increased research on alternate modes of pest management. Among these, allelopathic strategies (Botanicals, intercropping and mixed cropping, etc) seems to have considerable potential, hence, research in these areas is being conducted in many parts of the world. There are various mechanisms of allelopathic interactions that help in reducing pest populations. Along the same lines, following a period of increasing specialisation and monoculture, the growing realisation of the environmentally-friendly qualities of traditional agriculture has resulted in the increasing use of certain agronomic principles such as mixed cropping.
