UV Water Disinfection for Agriculture & Horticulture Applications

UV-Guard supplies UV water purification systems specifically designed for the Agriculture and Horticulture industry. Our systems provide farmers and operators with confidence that their irrigation water is free from plant pathogens such as bacteria, fungi, viruses and nematodes. Due to the large scale of crop production, a pathogen outbreak can have a detrimental impact on harvest volumes and crop quality leading to loss in profits.

Additionally, our UV water purification systems help playing field and garden maintenance managers meet regulatory requirements, ensuring their irrigation water is safe for both plants and for human contact.

Water scarcity has resulted in farmers and maintenance managers seeking alternate water sources. Our UV systems can be implemented to control plant pathogens in the following water sources to enable its safe re-use:

  • Drain water – recycling irrigation water within hydroponic applications
  • Storm, Rain & Dam water – storing, treating and recycling captured storm water
  • Ground Water – pumping out from bores for an alternative water source

UV-Guard analyse potential water sources and provide UV Transmittance (UVT) testing in our laboratory to recommend pre-treatment and to ensure the correct UV system is specified. Depending on the target plant pathogen, we design UV systems to achieve UV doses of between 30 mJ/cm² (playing field irrigation) to 150 mJ/cm² (Phytophthora & Pythium control) and 250 mJ/cm² (Fusarium control).

UV-Guard have a collaborative relationship with the Nursery & Garden Industry Australia (NGIA). We have provided support to research programmes and guidance in the use of UV as a disinfestation method.

Engalls Nursery – Dam water UV disinfection for irrigation of citrus trees

Engalls Nursery are specialist growers of citrus. Since 1976 they have been growing citrus and fruit trees at their 4 hectare nursery in Dural, NSW. Their crop is irrigated using dam water stored at the lowest point of the nursery.
