"We applied StimBlue+ twice on our potato field in June. In a drone shot, we can see changes in greenness in the treatment zone (where StimBlue+ was applied). This part of the field looked greener compared to the standard plot, where we didn’t apply it.”
HIGHER YIELDS
In a trial in the United Kingdom (2025), plots treated with StimBlue+ at a rate of 2 L/ha showed significant increases in yield, total count of potatoes and the count and weight of potatoes between 65-86 mm (above industry standard).
ENHANCED PLANT EMERGENCE

Potatoes were soaked in a 4% solution for 10 hours before planting, followed by 2 foliar applications to assess crop development after soaking treatment (Spain, 2025). Potatoes treated with StimBlue+ showed significant enhancements in early plant growth compared to the control and Ecklonia-based competitor.

This approach ensures the plants receive support at critical growth stages. The results are based on StimBlue+ suggested application rates and calendars. For foliar applications, it is recommended to spray in the morning or late in the day during non-sunny or humid weather.
