1,4SEED®

For seed potatoes: the one and only dormancy-extending product available anywhere for use in seed storage – highly effective and based on nature’s own dormancy solution.

1,4SEED® OFFERS:

  • NATURE’S OWN DORMANCY SOLUTION: 1,4SEED® is NOT a sprout suppressant. Rather, it is a fully reversible, naturally-occurring dormancy enhancer that wears off – just as it would in nature – as it volatilizes out of the tuber.
  • LESS STORAGE LOSS: 1,4SEED® allows tubers to store their energy rather than using it up through early sprouting. Saving energy not only translates to less shrink and more salable weight for seed producers, it also means seeds have much better vigour at planting.
  • STABILIZED SPROUT-FREE DORMANCY: 1,4SEED® enhances dormancy throughout the storage season, even in stressed tubers, to maximize seed vigour at planting. It can also re-establish dormancy in tubers that are starting to peep.
  • MAXIMUM FLEXIBILITY: 1,4SEED® ensures your seed tubers stay contentedly dormant if spring comes to your region before it warms your customers’ fields. Plus, 1,4SEED® supports ongoing dormancy even when storage is warmed during partial shipments.
  • BETTER CROP STAND UNIFORMITY: In most varieties, 1,4SEED® can reduce seed tubers’ apical dominance. Encouraging more eyes to emerge at the same time results in more uniform crop stand emergence, more even growth throughout the growing season, and easier, more effective pest and pathogen management. As such, a field planted to 1,4SEED®-treated seed has the potential to achieve a better and more even tuber set, more stems per plant, and – so long as you get your crop management right – a higher-quality crop.
  • ZERO RESIDUE CONCERNS: Formulated from a naturally-occurring chemical that entirely volatilizes away, 1,4SEED® poses no residue concerns of any kind.
  • BONUS! LESS VISIBLE BRUISING: More and more producers are reporting that early applications of 1,4SEED® appear to reduce the impact of pressure bruise in seed potatoes. While 1,4SEED® cannot remove bruising, it triggers the production of enzymes in tubers that – anecdotally at least – make bruising significantly less visible. We’re working with independent ag researchers to better understand the mechanisms and best management practices of using 1,4SEED® for bruise control.

HOW DOES 1,4SEED® WORK?

1,4SEED® is formulated from 1,4 Dimethylnaphalene (1,4-DMN), a dormancy-enhancing hormone that potato plants naturally produce. Fogged onto a pile as a vapour, 1,4SEED® flows through even a settled pile easily. Once it is absorbed by each tuber’s skin, 1,4SEED® triggers the production of enzymes that temporarily suppress cell division and sprout growth. 1,4SEED®’s sprout suppression is temporary and fully reversible. The speed at which the hormone wears off can be controlled by storage temperature, ventilation and application rate.

APPLICATION

1,4SEED® can be applied throughout the storage season until close to shipping and planting, allowing a producer exceptional control over dormancy’s timing. 1,4SEED® suits all common varieties of seed potatoes. Contact your applicator to discuss optimizing treatment for specific varieties, your storage conditions, and your shipping priorities.
