Abstract Agriculture is the backbone of developing countries, which plays an essential role in primary drivers of economy. The increasing use of chemical fertilizers and toxic insecticides endangers the health of human, plant soils, and the environment. Microbial insecticides have been implemented in current scenario for crop protection. Biological agents for pest control have gained more attention in recent year as substitutes for management of pests and pathogens. It provides a sustainable approach to plant health management and assists to minimize the excessive applications of toxic substances. The antagonistic microbes belong to six different phyla including Bacillota, Actinomycetota, Pseudomonadota, Bacteroidota and Mucoromycota. Microbial pesticides have been developed through a number of processes, including extraction of pure culture and screening using effectiveness bioassays under controlled and natural conditions. Biological control agents (BCAs) are recognized to be the most sophisticated technology for environmentally friendly agriculture. The various beneficial BCAs have been reported for the management of plant health, but they required effective acceptance together with the standardization of bioformulation. The present review deals with the recent development of microbial control agents, mechanisms of actions, development of microbial pesticides and their potential applications for agricultural productivity.
