Methyl jasmonate is widely used in agriculture as a plant growth regulator. It helps in enhancing the resistance of plants against various environmental stresses, such as drought, salinity, and pathogen attacks. By acting as a signaling molecule, it triggers the plant's defense mechanisms, leading to the production of secondary metabolites that protect the plant.

In horticulture, it is applied to improve the quality and shelf life of fruits and flowers. It promotes the synthesis of beneficial compounds like antioxidants and essential oils, which contribute to the aroma, flavor, and nutritional value of crops. Additionally, it is used in post-harvest treatments to delay ripening and reduce spoilage.

In research, methyl jasmonate is utilized to study plant signaling pathways and stress responses. It serves as a tool to understand how plants adapt to adverse conditions and develop strategies for crop improvement. Its role in inducing systemic acquired resistance makes it a valuable component in sustainable farming practices.

Furthermore, in the fragrance and cosmetics industry, methyl jasmonate is employed as a key ingredient to create natural jasmine-like scents that evoke freshness and relaxation.
