About the Presentation

Chitosan is a naturally occurring compound that has been utilized to induce plant defense systems and as a bio-fungicide, bio-bactericide, and bio-virucide, as well as to help plants respond to various abiotic stresses.

Research has reported positive effects on rhizobacteria growth and improved plant nutrient uptake. Chitosan can activate plant defense signaling pathways, promoting root growth, wound healing, plant water regulation, and more.

Join us to learn more about chitosan, its mode of action, and how it can be incorporated into the toolbox of a landscape IPM/PHC program.

Please arrive at 6:30 PM for dinner and sign-in.
