Chitosan induces systemic acquired resistance (SAR) in plants, enhancing their natural defense mechanisms. Its ability to form a protective barrier on plant surfaces prevents fungal spores from germinating. Chitosan activates defense-related genes, triggering the production of antimicrobial compounds. In integrated pest management (IPM) programs, chitosan is a valuable tool for reducing reliance on synthetic fungicides. Its biodegradable nature minimizes environmental impact, making it a sustainable choice for disease control. Chitosan is effective against a wide range of fungal diseases, including powdery mildew, blight, and rot. By promoting plant health and resilience, chitosan reduces the incidence and severity of fungal infections. Its ease of application makes it a practical solution for both small-scale and large-scale farming operations. Chitosan also improves the shelf life of harvested crops by preventing post-harvest fungal decay. As a biofungicide, chitosan provides a safe and effective alternative to conventional chemical treatments, protecting both crops and the environment. Chitosan works by creating a hostile environment for fungi, preventing them from taking hold and causing damage. It's like having a natural bodyguard for your plants, keeping them safe from fungal invaders. With chitosan, farmers can protect their crops from devastating diseases while promoting sustainable and environmentally friendly practices. This makes chitosan a key player in modern agriculture, ensuring healthier plants and higher yields.

Chitosan in Seed Treatment

Let's talk about seeds, guys. Giving them the best start in life is super important for a successful harvest.
