Many plant pathogens (viruses, bacteria, fungi and nematodes) spread via the water recirculation system. To prevent contaminated water from being used in the recirculation system, many greenhouse growers install a disinfector. But there is no guarantee that this expensive investment will deliver the expected results.

If you want to be sure that your disinfector is working properly, ask us for a DisinfectorCheck. For this analysis, we take a water sample before and after the disinfector. The sample then goes to our microbiology lab, chilled and in sterile bottles. In the lab we determine the aerobic plate count (the number of bacteria and fungi) and the total number of fungi. We check that your disinfector is working properly by comparing the results of the two samples side-by-side.


The Eurofins Agro DisinfectorCheck is accredited by the Dutch Accreditation Council to ISO 17025. This proves that we perform the analysis to extremely high standards of reliability in accordance with the guidelines. The analysis is a snapshot, so if you want to be sure that your disinfector is working properly, we recommend having the analysis performed at least four times a year. DisinfectorCheck is suitable for all types of disinfectors (heat, UV radiation or oxidation with ozone or hydrogen peroxide).
