Do microbial pesticides control microbes in the plant or soil?

Microbial pesticides are designed to control target pests, which can often include harmful microorganisms, but they do not work by controlling microbes in plants or soil directly. Instead, these pesticides utilize beneficial microbes that can help suppress or outcompete harmful pathogens, thereby improving plant health.

While microbial pesticides may have indirect effects on soil microbes or plant-associated microorganisms by promoting a healthier balance, their primary mode of action is not about controlling microbes in those environments. Therefore, the idea that they simply control microbes broadly in plants or soil does not accurately reflect the specialized nature of their function. It's important to recognize that the efficacy of microbial pesticides often relates to their interaction with specific pests rather than a universal application against all microbes within a plant or soil ecosystem.
