UVRER offers horticultural professionals complete and adapted cleaning solutions to resolve contamination problems in all areas of the production process:

  • Recycling and disinfection of nutrient solutions
  • Recycling and disinfection of post-harvest solutions
  • Elimination of suspended bacteria and fungi in cold rooms
  • Disinfection of petals and stems before packaging

Like any fresh product, cut flowers are extremely fragile and perishable. They therefore require specific handling and treatments to ensure optimal presentation and preservation.

Botrytis Cinerea

In a confined and humid atmosphere, the flowers can develop a mold on the petal, Botrytis Cinerea, which makes them unsuitable for marketing. Flowers can be contaminated by this fungus through air, water or direct contact with other affected flowers.

This micro-organism, which develops even in refrigerated premises (positive cold), is responsible for significant losses, due to poor presentation but also poor preservation. These very easily airborne spores can, through cross-contamination, attack all the flowers on the premises and cause significant financial losses.

Are you facing this problem?


As a substitute for the necessary treatments by spraying in cultivation or dipping at harvest, one of the common solutions is to treat the air in warehouses using fungicide fumigants, but this is expensive, dangerous for staff and this process leaves deposits on all surfaces. It is also important to note that numerous studies highlight the ability of Botrytis strains to become resistant to the chemical substances usually used.


Discover UVDT, an industrial concept of order preparation and processing before packaging allowing the drying and disinfection of flowers before shipment, by directly treating problematic microorganisms at the source, at the surface of the flowers.
