In controlled-environment agriculture (CEA), airborne diseases are a major factor affecting crop yield and quality. Common diseases such as powdery mildew, downy mildew, and gray mold spread through the air and can quickly affect large areas of crops, increasing the difficulty and cost of control. Traditional control methods often rely on chemical pesticides; however, excessive use can lead to pesticide residues, the development of resistance, and environmental pressure. Identifying efficient, environmentally friendly, and sustainable control methods has become a priority in cultivation management.

UVB Ultraviolet Light Solution for Airborne Disease Control

LumiAgro has specialized in plant supplemental lighting for 10 years, integrating research in plant physiology and pathology to provide UVB ultraviolet light solutions for airborne disease control in greenhouses and plant factories. This solution employs specific UVB wavelengths to reduce the risk of airborne diseases without the use of chemical agents.

Mechanism of Action:

Suppressing pathogen activity: UVB damages the genetic material of airborne pathogen spores, inhibiting their reproduction and spread, thereby reducing the risk of disease at the source.

Enhancing plant resistance: Proper UVB exposure can trigger the production of defensive metabolites in plants, thereby enhancing their resistance to disease.

Technical Advantages:

Reduces pesticide use and supports environmental sustainability

Compatible with multiple disease management measures

IP65 protection rating for challenging environments

Durable and easy to install

Applicable Scenarios:

Auxiliary airborne disease control in greenhouses

Disease management in plant factories

[Application Case] UVB Ultraviolet Light in Strawberry Disease Management

Multiple authoritative studies have shown that UVB exposure enhances plant disease resistance and suppresses pathogen activity, showing strong effectiveness in controlling airborne diseases such as powdery mildew and gray mold.
In strawberry greenhouse trials, proper configuration and use of UVB ultraviolet light helped lower disease incidence, reduce the frequency of pesticide applications, and, to some extent, improve fruit quality and yield.

China Agricultural University
Experimental reports indicate that UVB exposure can improve plant resistance, inhibit pathogens, effectively control common diseases such as powdery mildew and gray mold, reduce pesticide use, and enhance fruit quality.

Institute of Pomology, Jiangsu Academy of Agricultural Sciences
Experimental data show that the relative control efficacy of UVB against strawberry gray mold ranges from 60.94% to 79.88%. Among these, UVB combined with normal pesticide use achieved the best control effect at 79.88%. In contrast, using only regular pesticides achieved just 5.72%, likely due to the development of pathogen resistance, resulting in reduced efficacy.

LumiAgro will continue to leverage lighting technology to support the green development of CEA, providing efficient and environmentally friendly solutions for growing bases and partners.
