Sustainable biostimulant from freshwater cyanobacteria for crop production
A soil-applied biostimulant derived from freshwater cyanobacteria that enhances plant defense and disease resilience, offering a sustainable alternative to synthetic inputs. This innovation leverages local, renewable resources for scalable agricultural solutions.
Overview
The sustainable biostimulant developed from freshwater cyanobacteria offers an innovative approach to enhancing crop production by activating systemic plant defense mechanisms. When applied as a soil drench, the metabolites in the cyanobacterial liquid culture prime plants to better withstand pathogen attacks, resulting in improved disease resilience. This biologically driven strategy not only strengthens plant health but also reduces dependence on synthetic disease management products.
