Agricultural producers are confronted every day with two great challenges: the need to optimise water resources available and the need to increase the productivity of the area cultivated. These issues have led to the diffusion of intensive cultivation systems in particular cultivation without soil (e.g. hydroponic systems) and the need to reuse water coming from other sources or other processes for irrigation.
Water is the vehicle and nourishment for plants, which is why it must be ensured that it is purified from pathogens such as bacteria, viruses, algae, spores and nematodes. In the same way in the use of recirculating greenhouse systems or external waters recycling, it is necessary to use disinfection systems to prevent the rapid spread of plant pathologies.
The use of ultraviolet systems in agriculture is becoming increasingly common, considering the countless applications in the treatment of a fundamental resource for cultivation as water. In recirculation systems of hydroponic crops, ultraviolet treatment protects from the rapid and uncontrolled spread of plant diseases.
In cases of water scarcity, UV is used both for the treatment of water stored in tanks and for the storage and use of rainwater, both potentially full of pathogens. In these cases water needs even more attention than is reserved for water used by mankind. Spores and mushrooms are known for their high resistance to particularly difficult conditions.
