Pests are mostly to blame for significant crop losses, decreased food supplies, lower-quality agricultural output, and difficult financial times for farmers and processors. Chemical control techniques are typically used to manage them, however they are not always cost-effective or efficient and may pose unintended dangers to human health, safety, or the environment. But in order to meet the challenge of feeding the world's growing population, effective, affordable, and environmentally friendly disease control strategies are essential. By using natural enemies, biological control could be a useful strategy for minimizing or eliminating pests and their impacts. Utilizing helpful microorganisms to manage plant infections and the diseases they cause is known as biological control, and it is an environmentally sound method.  The effectiveness, benefits, and safety of employing biological agents to prevent and manage pest damage to crops are outlined in this paper. It has been universally demonstrated that bio-control is safe for humans, animals, plants, and the environment.  This stands in stark contrast to chemical insecticides, which are more commonly utilized and frequently cause contamination in the environment that harms both people and the ecosystem. Manufacturers of bio-control products are always creating new procedures for determining agent safety, implementing, and gauging treatment efficacy. Regulations are being developed by the government and manufacturing associations to ensure the responsible and safe application of biocontrol. The advantages of biological control systems are what propel the technology's growing popularity.  The use of bio-control platforms should be encouraged for the obvious reasons of biodiversity protection and high benefit to cost ratio. To adopt these alternative agricultural approaches, the general public and those in the agriculture industry will need to be educated and made aware of them.
