The undocumented use of pesticide and insecticide has been causing a great deal of pollution in our nature. Irresponsible use in huge quantity is affecting all the biosphere, atmosphere and hydrosphere. The impact on human health and the stability of the ecosystem is also increasing day by day. People are being fed poison coated fruits and vegetable everyday. But the fact that their use can be completely abandoned by us is still a mystery. No, if we plan on sustaining the increasing population with the present food resources, the complete avoidance of pesticide and insecticide cannot be done. But an easier, economic and environment friendly approach does exist. This approach is named as IPM(Integrated Pest Management). IPM is being adopted by many countries of the world and is an easy way to control pest without affecting the health of both humans and environment. IPM is a cumulative approach that aims at maintaining the pest level upto the point they are not harmful to us, through the combined use of physical, cultural, biological, mechanical and lastly chemical. It operates on the belief that pest are needed for ecological stability but only to the point upto which they do not affect us and chemicals are to be used but only as last resort in pest control.

Some basic principles of IPM are:

1) Physical method: Here the pest are controlled by physical manipulation of temperature and light. Some easy use of this method is the increase in temperature of go downs to 50degree Celsius or use of light trap to trap nocturnal pest and others.

2) Cultural means: It is an easy one being used by most of the farmer. It uses safe and clean farming practices like use of clean seed, deep tillage of soil, crop rotation, use of trap crops, solarization of soil and others.

3) Mechanical means: It imposes on use of mechanical methods usually  suitable for home gardens like use of water traps, wrapping of fruits, collecting and killing of large insect, covering of harvest by saw dust, etc.

4) Biological method: As the name implies it focus on use of biological means like use of predators, entomopathogenic virus and bacteria, pheromones and allelochemicals.

5) Chemicals: Chemicals like insecticide are to be used but only as last means. Here only verified, less hazardous, non-persistent pesticides are allowed to use. The use of bio-magnified ones like DDT, BHC is completely avoided. 

So the sustainable use of IPM approach can be a great in promoting the sustainability of farms but its proper application should be ensured.
