Description

Harpin(Pss) Protein is a naturally occurring, plant-derived elicitor protein that activates systemic acquired resistance (SAR) in plants. This compound matters because it offers a powerful, eco-friendly tool for enhancing crop resilience against a broad spectrum of bacterial, fungal, and viral pathogens without direct antimicrobial activity. Agricultural researchers, biopesticide formulators, and plant health companies need it to develop next-generation biocontrol agents and plant defense stimulants for sustainable agriculture.

Application

• Active ingredient in biostimulant and biocontrol formulations for integrated pest management (IPM) programs.
• Research and development of novel plant defense activators and elicitor-based crop protection products.
• Component in seed treatment solutions to enhance early seedling vigor and disease resistance.
• Use in horticulture and floriculture to improve plant health and reduce chemical fungicide reliance.
• Studies on plant-pathogen interaction mechanisms and systemic signaling pathways.
• Formulation of organic and sustainable agriculture products compliant with global regulatory standards.
