Plant Health / Fighting Plant Diseases with Ultraviolet (UV) Light
UV energy can increase plant health and productivity and improve the health of soil and aquatic systems by reducing the amount of pesticides introduced into the environment
UV energy can increase plant health and productivity and improve the health of soil and aquatic systems by reducing the amount of pesticides introduced into the environment
What We Do
What We Do
LHRC researchers and our collaborators have demonstrated the power of UV energy to combat several types of plant pathogens more effectively than commercial pesticides:
Considerably reduced strawberry powdery mildew
Nearly eliminated angular leaf spot on squash
Significantly reduced cercospora leaf spot on table beets
Harness UV from sunlight to fight plant diseases in greenhouses
Where We Are Going
Where We Are Going
Educate growers on how to safely and effectively apply UV energy in field applications in place of conventional pesticides.
Advancing the state of the art by developing new UV LED (light emitting diode) systems to be able to apply UV energy more effectively and economically to a wider range of crop types.
Conduct laboratory and field research to further investigate the use of UV energy, including in combination with photocatalytic compounds, to fight additional types of plant pathogens and diseases.
