Restrain welcomed growers, seed producers, agronomists and other key industry stakeholders to its Open Day, held in partnership with Cockerill’s, Malton, on 23 July 2026. The event brought together leading figures from across the potato sector to demonstrate AccumulatR™ , Restrain’s potato seed treatment designed to improve seed efficiency and increase marketable yield. A highlight of the day was a season update from Restrain’s trials partner, Gavin Prentice of SAC Consulting , who shared observations from current field trials and discussed the challenges and opportunities facing growers this season.

AccumulatR™ uses a carefully controlled combination of ethylene and temperature management during storage, applied through Restrain’s treatment protocol for 120+ days prior to planting . The treatment encourages an increase in the number of stems produced per seed tuber, resulting in more tubers per plant. In addition to increasing tuber numbers, AccumulatR-treated seed promotes quicker and more uniform crop emergence . This supports a more even tuber size distribution across the crop, helping growers maximise output within target market specifications. The combined effect of increased tuber numbers and improved size uniformity delivers higher marketable yields in both Seed Multiplication (28-55 mm) and Salad Production (28-45 mm) . This increased proportion of saleable potatoes is a key factor in improving overall seed efficiency, crop value and returns per hectare.

AccumulatR™ is not a new concept for UK growers. The technology has been used commercially for more than 20 years , with customers located throughout the country, from the Black Isle in Scotland to Norfolk. Over that period, the treatment has demonstrated consistent results across more than 200 potato varieties, supporting both seed multiplication businesses and salad producers.
Beyond increasing marketable yield, AccumulatR™ helps maximise the value of every tonne of seed planted. By producing more marketable tubers within target size specifications, growers can improve seed efficiency while making better use of available resources. As the potato industry continues to focus on both profitability and sustainability, achieving more output from the same seed inputs remains a key priority for many businesses.
Restrain is also investigating how AccumulatR™ can improve seed efficiency in ware production. By increasing the number of stems produced per seed tuber, the treatment may enable growers to reduce seed rates while still achieving target stem densities. Early trial work is exploring the potential to lower input seed requirements while maintaining crop performance, creating further opportunities to improve the efficiency and profitability of potato production.
