1,4GROUP sells dormancy-enhancing and sprout-inhibiting agricultural chemicals for the potato storage industry, targeting distributors and applicators who desire innovation and a high level of customer service.  Unlike our competitors, we offer the 1,4-DMN family of products, which are naturally occurring in the potato, and provide numerous other benefits, such as superior storage characteristics, resulting in higher yields and greater flexibility. At 1,4GROUP, we back our customers with extensive support before, during, and after the sale, including applicator training to ensure success.

For fresh pack or processing potatoes, our products nip sprouts in the bud!


"1,4GROUP's DMN products have been a long time component of our storage treatment plans.  Spuds treated with 1,4SIGHT in combination with CIPC result in better sprout control and improved quality out of storage.  I apply it in the fall or early spring in storage, depending on the natural dormancy of the variety.  They hold better and seem firmer with fewer sprouting problems.
We also use 1,4SHIP, and in-transit sprout treament, to extend dormancy and aid the appearance of shipped potatoes."
--Kent Peterson, Kemco/Wada Farms

"We have used 1,4GROUP's DMN products for seveal years.  We apply 1,4SIGHT shortly after we place our potatoes into storage.  It helps control sprouts and extends dormancy, safe guarding the potato quality into the summer.  1,4SEED is applied to our seed potatoes when sprouting gets out of control.  It works great."
-Doug John, Field Manager for Potandon Produce LLC

"As a grower/shipper we need to ensure that our potatoes are peep free.  Using 1,SIGHT allows us to achieve this goal.  1,4SIGHT also provides us wth the added benefit of reduced shrink and pressure bruise."
-Dan Moss, Moss Farms/Arrowhead Potatoes
