What is biological control why is it an important component of IPM and biological control methods be preferred for protecting crops?
Biological control of insect pests and diseases through biological means is most important component of IPM. In broader sense, biocontrol is use of living organisms to control unwanted living organisms (pests). Preventive measures and biological control methods should be preferred for protecting crops because these methods are ecologically safe and these methods do not harm various life forms. The high use of chemicals causes many environmental problems and leads to pollution.
Preventive and biological methods are environment friendly, target-specific, do not cause pollution and are harmless to other life forms, they are preferred for it protecting crops. Over expose of chemicals leads to environmental problems hence, biological methods are preferred for protecting crops from pathogens, insects, and rodents along with increasing the production. Biological control is the use of one biological species to reduce populations of a different species. There has been a substantial increase in commercialization of biocontrol products, such as beneficial insects, cultivated predators and natural or non-toxic pest control products. Biological control of insect pests and diseases through biological means is most important component of IPM. In broader sense, biocontrol is use of living organisms to control unwanted living organisms. Biological control is the use of living organisms to suppress pest populations, making them less damaging than they would otherwise be. Natural enemies of insects play an important role in limiting the densities of potential pests. These natural enemies include predators, parasitoids, and pathogens. Regulating the Ecosystem to Protect and Promote Natural Enemies or Competitors of Pathogens. Plant disease often results from a disordered ecosystem [80]. The success of biological control relies on a healthy ecosystem provided by predators, competitors, promoters, and other species.
