Abstract

Biopesticides, an alternative to chemical pesticides, are typically derived from living organisms, microorganisms, and other natural sources. Microorganisms such as bacteria, fungi, viruses, or protozoans as an active ingredient can control varieties of pests and exhibit specificity for their target pests. Certain weeds can be controlled by some fungi, whereas other fungi can target and kill specific insects. None of microbial, biochemical pesticides and plant-incorporated protectants can be obtained from various microorganisms which confer protection against pest damage. Some of the additional benefits of biopesticides include complex and novel modes of action against their target pests and efficient resistance management to extend the product life of conventional pesticides. Biopesticides pose less risk to people and the environment as compared to synthetic pesticides and hence gain global attention as a new tool to kill insects and plant pathogens and suppress growth of weeds. In this chapter, the global scenario of biopesticides is discussed with special reference to its current demand, use, constraints, and remedies.

Keywords: Biopesticides, Active ingredients, Constraint and remedies, Genetic incorporation, Agricultural commodities.
