Contamination Control of Growth Media

Horticulture is a challenging area to work within due to product demands for specific growth media, the challenge of minimizing product spoilage due to contaminants, as well as ensuring that product volumes are sufficient to meet your Customers’ demands. All of these factors are critical to the success of a business.

What are the challenges?

There are two main challenges for minimizing contamination. The cleaning of growing trays is possibly the most difficult element for horticulture companies. It is widely accepted that this ‘cleaning’ is a timely and costly process – yet despite this, it is also widely acknowledged that washing is not the most effective method for horticulture contamination control. The washing process can be labor-intensive and requires significant investment in washing equipment. There is also a risk of post-washing contamination, which can result in the spoiling of a large number of products.

Waste management is the second critical element of managing the growing process. New laws have imposed strict levies on all businesses where there is significant waste from the manufacturing process, with the volume of cultivating pots and trays increasing with market demand, the risk of incurring some waste management fees also proportionally increases.

How can we help?

With changes in legislation eliminating the use of soil partial-sterilants and problems with fungicide residues in some crops, the horticulture market is starting to appreciate the need for more suitable methods of biological control of contaminants. Although various pesticides and bacteriological agents are being developed, viral agents, their fungal vectors and fungal pathogens are still a challenge.

Irradiation is a proven technology that is widely used across the world to eliminate potentially harmful pathogens from growth media & associated products and STERIS Applied Sterilization Technologies (AST) has been working with horticulture Customers for many years, helping them effectively decontaminate their growing trays, pots and other equipment, with greater efficiency than could ever been realized by current washing techniques. Some of the products regularly processed by STERIS AST include:
