Abstract

Biopesticides are derived from living organisms and naturally occurring materials. These compounds are classified as biochemical, microbial and genetically derived pesticides in the form of the active ingredients. Currently, biopesticides share only about 5% i.e. $3 billion worldwide in terms of the crop protection market. Chemical pesticides are heavily deployed in commercial agriculture for the management of pests and pathogens. However, they come with unaccountable threats and poses risk to the environment as well as all the living creatures including humans. An alternative approach to limit the use of chemical pesticides would be the use of biopesticides, which have proven to be eco-friendly, comparatively safer and sustainable from several research studies. Nevertheless, with the advancements in genetics, genomics and molecular biology in the present era, the international research community has been intensively focused to determine the genetic aspects of microbial pesticides and their pragmatic use for the management of pests and pathogens. This paper reviews current technological applications on the use of biopesticides from genetics, genomics and molecular biology perspective along with future directions for the safe and sustainable management of the agricultural pests and pathogens.
