RÉSUMÉ
Plant stress generated by various climatic and anthropogenic activities has exacerbated the degradation of agricultural systems and productivity throughout the developmental era, and it is currently recognized as the world's most significant and possibly deadly danger impacting crop plant economic output. Nonetheless, phytohormones have been found as a potent tool for minimizing the detrimental effects of stressors in agricultural plants in a sustainable manner. Salicylic acid (SA), one of the most important phytohormones, is required for the regulation of plant growth, development, ripening, and defensive responses. A lot of interest has been generated by SA's defensive mechanism. Major agricultural crops' ability to withstand stress has been said to be much improved. SA utilization is influenced by the amount of SA applied, the application method, and the state of the plants (such as their developmental stage and level of acclimation). In this review, we have focus on the efficacy of SA on mitigating various plant biotic and abiotic stress under adverse environmental conditions and its role on plant growth, development and productivity.
