UVC light

UVC light effectively destroys the DNA of actively growing fungi. As a result, the fungi die before causing any damage to your turfgrass. This decreases the disease pressure of your playing surface and diminishes the chance of disease outbreaks. Importantly, grass cells are much more resistant to UVC light compared to fungal cells. Thus, the UVC180 radiates a sufficiently high level of UVC light to eliminate fungal cells while leaving the grass plants unaffected. The effectiveness of UVC treatment depends on its spectrum and dosage. The UVC180 operates at a wavelength of 253.7 nm, a range of which research has proven to be the most effective against viruses, bacteria, and fungi. For over 40 years, UVC radiation has been used to disinfect water, air, pharmaceutical products, and surfaces. Microorganisms, including fungi and viruses, possess genetic material—either DNA or RNA. DNA molecules consist of two strands bound together by four bases: adenine (A), cytosine (C), guanine (G), and thymine (T). When biological organisms are exposed to UVC light within the range of 200 nm to 280 nm, the light penetrates their cell walls and disrupts the DNA molecules, specifi cally targeting the thymine bases. Disrupted DNA becomes unable to replicate, leading to the demise of the fungi or virus before it can harm your turfgrass or players.

The science behind UVC light

The sun emits radiation of various wavelengths. Some of this radiation is visible to the human eye, such as the light forming the colours of the rainbow. The portion of radiation beyond the violet end of visible light is known as Ultraviolet (UV) radiation, which our eyes cannot perceive due to its shorter wavelength and higher frequency compared to the light our brain sees as images. UV radiation consists of three types of rays: UVA, UVB, and UVC. UVA light has the longest wavelength and passes through the ozone layer, reaching the Earth. It’s the least harmful UV light and is commonly known as “black light.” UVB light causes sunburns with prolonged exposure and increases the risk of skin cancer. Approximately 95% of all UVB light is absorbed by the ozone in Earth’s atmosphere. UVC light is very harmful to living organisms, which is why it’s often used as a disinfectant in food, air, and water to kill microorganisms. UVC is entirely absorbed by Earth’s atmosphere.

Data driven technology

The SGL Portal is the online management tool for all SGL products. It is where all data of the products and monitoring tools is displayed, as well as where data calculations and analyses are done in the background, to provide grounds managers with the information to make proactive decisions. With the UVC180, a seven-day disease forecast provides insight into potential diseases for the upcoming week. Using data from your specific location, this forecast determines the recommended frequency and settings for utilising the UVC180. The necessary treatment frequency of the UVC180 depends on the level of disease pressure. Our algorithm calculates the pressure of many different fungi for your playing surface, using local weather forecasts and, when accessible, growth data from the monitoring equipment. This information will be displayed on your personal online Portal, together with the required frequency of UVC180 usage. You can get active support from a disease expert in our agronomy team, to help you take the right proactive measures and prevent disease outbreak.
