Endophytes are used as biocontrol agents in plant disease management and sustainable agriculture. The numerous endophytic microbes residing in a plant’s internal tissues can impact the plant positively or negatively. Beneficial endophytic fungi can directly or indirectly enhance plant health, enabling plants to withstand potential dangers. Plant infections may result from inadequate farming practices and environmental factors. The symbiotic relationship among endophytic fungi and host plants leftovers a vital progressive action in disease control. To address issues with endophyte biocontrol mechanisms, a thorough understanding of the interactions among pathogens and host plants is required, in addition to selecting and using beneficial endophytic fungi. Endophytic fungi, which produce a significant number of biologically active compounds, can be instrumental in managing biotic and abiotic challenges. Consequently, it is increasingly common to search for these microbes that produce beneficial agricultural products.
