UVC Disinfection for Horticulture
UV light can be divided in four main categories, UV-A, UV-B, UV-C and Vacuum UV. The UV-C spectrum (200 to 280 nanometers) is the most lethal range of wavelengths for microorganisms. UV-C light has the ability to cause permanent damage to microorganisms.
Each type of microorganism requires a specific UV-C radiation exposure rate to successfully complete the disinfection process. The targeted microorganism must be directly exposed to the UV-C radiation long enough for the radiation to penetrate the microorganism’s cell wall. However, it takes only a fraction of a second for UV-C light rays to inactivate waterborne microorganisms by breaking through the microorganism’s cell wall and damaging their DNA. This often totally destroys the organism, or at the very least will impair its ability to reproduce.
Benefits of UV-C disinfection
- Savings on pesticide sprays
- Improved crop quality
- No residue on the crops
- Less stress for the crops
- Ensuring a healthy environment for greenhouse workers
- Biological control agents are not harmed
