Many chemical compounds produced by plants protect them from pests; they are called antifeedants. These materials are biodegradable and renewable, which can be economical for practical use.

Antagonism plays a critical role in agriculture, particularly in the development of biological control agent (BCAs) to manage phytopathogens and reduce reliance on synthetic pesticides. [16] Numerous microbial antagonists, including yeasts and bacteria , are isolated from diverse environments such as soil, plants, compost, and oceans for their ...
