"That certification has been accepted as a guarantee of compliance to GAP. Our total cleaning package has set the standard for the industry." PSI is now offering its own line of products. Recently, Harvest 6.0 was released as one of the strongest disinfectants labeled for potatoes. Harvest 6.0 is a sanitizer for potatoes in storage that utilizes hydrogen peroxide and peracetic acid to protect against fungus, algae and bacteria. "It's turned out to be one of the strongest disinfectants in the industry," says Mortensen. "We're really excited about this product. It can be applied to potatoes going into storage and to potatoes already in storage. It is also our best disinfectant on equipment and cleaning storage facilities." Today, PSI uses Harvest 6.0 for commercial growers and StorOx 2.0 for seed potatoes. Another one of the company's signature products is Bio-Ultra, a high-foaming detergent designed to penetrate deeply into heavily contaminated surfaces, breaking down contaminants and loosening them from storage walls. "Foam application is the key; this stuff is phenomenal," sasays Mortensen. "There will be mud or biofilm on storage walls, ventilation pipes and equipment that just won't come off with a pressure washer. With Bio-Ultra it just melts it right off. Then you can just follow the detergent with the disinfectant." The hard work and innovation over the last two decades have certainly paid off for PSI. "What's been the most satisfying," Mortensen says, "is that the customers we started with, we still have today. We have a great customer base." That customer base has expanded to stretch across Idaho, Montana, Nevada, and into Washington State. "Basically, our goal is to be everywhere they grow potatoes," Mortensen says. Anywhere PSI is able to expand, potato growers will be lucky to have them. PG
