By applying the UV treatment three times a week the technology substantially reduced the dollar spot infection.
When applying UVC light we use the range of the electromagnetic spectrum with wavelengths between 200 and 280 nanometers.
The UVC light’s wavelength largely coincides with that of the DNA’s (deoxyribonucleic acid) maximum absorption, which triggers a photochemical process when UVC light is applied.
The UVC photons modify the micro-organism’s DNA impeding further binary fission. The organism can thus no longer replicate and dies.
The application of UVC light has successfully reduced the use of fungicides in viniculture.
For more than five years the University of Geisenheim is doing research in this field!
A kill rate of close to 100% like in the food industry is not reached; however, depending on the part of the plant and light intensity, a reduction of up to 95% has been achieved.
A remarkable result has been achieved at Geisenheim University where it has been possible to reduce the use of fungicides from formerly 8 applications to a maximum of 3 applications.
Regular application of UVC light has been proven to successfully prevent snow mold and dollar spot infections.
A Germ tube formation
Our trials both in the field and the laboratory have shown that the application of UVC light is more effective than that of chemical pesticides.
In contrast to chemical pesticides, however, this innovative method of protection against turf diseases, which are caused by fungal spores on leaves and stems, comes without any potential risks or side effects.
In addition to the dangers it poses to the environment and our health, there is a considerable risk that resistances will develop when using chemical pesticides.
The primary difference compared to chemical, mostly oxidative, applications is the way in which UVC photons work by blocking the DNA.
This is the main reason why the development of resistances due to mutation is impossible when using UVC light.
Advantages of UVC light application without environmental impact
We have achieved good results with:
Cyanobacteria, green algae and diatoms
for which there has been no effective method so far,
are sustainably killed
A weekly exposure of greens, tees, and, where necessary, fairways to UVC light protects the turf from attack by fungi or algae.
There will never be a 100% guarantee for protection against harmful fungi on synthetic turf.
