Salicylic Acid has several applications in agriculture, primarily as a plant growth regulator and stress alleviator. Here are some primary uses of Salicylic Acid in the agricultural sector:

Plant Growth Regulator: Salicylic Acid acts as a plant growth regulator, stimulating plant defense mechanisms, and enhancing plant growth and development. It induces the synthesis of defense-related enzymes, such as phenylalanine ammonia-lyase (PAL) and chitinase, which contribute to plant resistance against biotic and abiotic stresses. Salicylic Acid-treated plants exhibit increased tolerance to diseases, pests, and environmental stresses, resulting in improved crop yields and quality.

Disease Management: Salicylic Acid is used in disease management programs to control fungal, bacterial, and viral diseases in crops. It activates systemic acquired resistance (SAR) in plants, triggering a cascade of immune responses that confer long-lasting protection against pathogens. Salicylic Acid-treated crops show reduced disease incidence and severity, leading to healthier plants and improved yield stability.

Stress Alleviation: Salicylic Acid helps plants cope with various abiotic stresses, such as drought, heat, cold, and salinity. It regulates osmotic balance, antioxidant defense, and stress-responsive gene expression, mitigating the adverse effects of environmental stresses on plant growth and productivity. Salicylic Acid-treated plants exhibit enhanced stress tolerance and recovery, ensuring sustained growth and yield under challenging conditions.
