About Us

We pride ourselves on providing professional, friendly, efficient customer service whilst remaining at the forefront of today’s product technology.

DormFresh Ltd was established in 2000 by Dr Harry Duncan and John Forsythe (Director/Owner 1,4GROUP, Inc.) with the prime intention to supply sprout suppressant chemicals to the European potato sector, in a safe and responsible manner. Their aim was to provide products which would help to improve the storage life of the potato whilst maintaining overall health and offer outstanding customer support at each stage.

DormFresh Ltd brought together research expertise built up over 50 years at Glasgow University by Dr Harry Duncan, coupled with the practical skills developed by John Forsythe, 1,4GROUP, Inc.

DormFresh Ltd today is based in Perth, Scotland providing dormancy potato products to the UK and Europe.

“1,4SIGHT® has been an essential component of sprout control for us at Wilhelm Weuthen for years. Thanks to its innovative mode of action, it keeps the potatoes optimally dormant. Early, preventative use, with follow-up applications tailored to the situation, ensures that we maintain the quality of our potatoes in the best possible way throughout the entire storage period.”

"1,4SIGHT® helps me to maintain the quality of my potatoes the best way possible throughout the entire storing period. By applying 1,4SIGHT® early, my potatoes stay dormant, leading to high quality, firm and therefore better marketable potatoes.”
