CATT stands for Controlled Atmosphere Temperature Treatment and was developed to control strawberry mites. Through certain temperatures, air compositions and humidity, pests on various plants are controlled in an environmentally friendly way.

Van Acht Refrigeration & Freezing Storage is a specialized and accredited CATT treatment location.
It is an environmentally friendly treatment method against pests in plants, developed by Wageningen University & Research Centre (WUR). In a separate department in our company, plants are treated with a combination of certain temperatures, air compositions and humidity. Besides being suitable as a treatment method to make plant material pest-free, CATT is also used as a quarantine treatment for import and export.
The principle is that plants undergo treatment in a gas-tight cell for a certain period of time. The treatment consists of a combination of elevated temperature and specific air conditions, such as the concentrations of oxygen and carbon dioxide in the air. Thus, no chemicals are involved. The CATT method is safe to use and poses no risk to humans, animals or the environment. Preconditions such as humidification and packaging can also be part of the recipe. For reasons of hygiene, CATT treatments are carried out in a separate department in the company.
For each pest-crop combination, the right combination of air composition, temperature, and treatment duration is determined. The CATT method has proven effective in combating strawberry mites in strawberry propagation material. Therefore, the method offers significant value for propagation companies.
Plants differ in their response to CATT treatment. However, for several crops there is very clear perspective for further development of CATT. Wageningen UR, HAS Den Bosch and Van Acht Koel- & Vriesopslag are currently searching for possibilities and the right formula to control pests in ornamental plant cultivation. Wageningen UR is researching the right balance. HAS Den Bosch and Van Acht are closely involved in carrying out the trials. At the CATT department at Van Acht, test setups are made according to procedures provided.
The CATT method has already proven itself in strawberry starting material. In ornamental plant cultivation, positive results have been achieved in several crops, with little or no negative impact on plant vitality.
