Description

Harpin CAS NO 147979-36-0 is a high-purity, plant-derived protein elicitor that activates systemic acquired resistance (SAR) in plants. This compound is critical for sustainable agriculture, offering a powerful, non-pesticide approach to enhance crop resilience against a broad spectrum of bacterial, fungal, and viral pathogens. It is an essential tool for agricultural researchers, biopesticide formulators, and producers of high-value crops seeking to improve plant health and yield through advanced plant defense mechanisms.

Application

• Plant Immunity Activator: Used as a key active ingredient in next-generation biopesticides and plant health stimulants to trigger systemic acquired resistance.
• Agricultural Research: Serves as a standard and experimental compound in phytopathology and plant biochemistry studies to understand defense signaling pathways.
• Seed Treatment: Incorporated into seed coatings to enhance early seedling vigor and disease resistance.
• Foliar Sprays: Formulated into solutions for direct application to crops, including vegetables, fruits, and ornamental plants, for broad-spectrum protection.
• Integrated Pest Management (IPM): A cornerstone component in IPM programs, reducing reliance on conventional chemical pesticides.
• Biostimulant Production: Blended with nutrients and other bio-actives to create comprehensive plant growth and health promoters.
