“With StimBlue+, we saw a unique boost in nutrient availability. Even through foliar application, BeCrop analysis confirmed these effects across fields, highlighting the reach and effectiveness of this biostimulant."
HIGHER YIELDS

Plots treated with StimBlue+ at 2 L/ha in a 2023 trial in Champagne, France, showed 24% greater yields compared to standard cultivation practices and 52% greater yields compared to the Ascophyllum-based competitor.
BIGGER SEEDS

In a trial assessing StimBlue+’s performance at different levels of fertilisation in France (2025), vines treated with StimBlue+ showed consistently higher levels of Nitrogen (N-tester).
application for
Wine grapes
+
+
FIRST APPLICATION
Foliar application | BBCH57 - before flowering
+
SECOND APPLICATION
Foliar application | BBCH73 - at fruit set
+
THIRD APPLICATION
Foliar application | BBCH79 - during ripening
+
+
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.
HOW TO USE STIMBLUE+
SHAKE IT
For its application, shake before use.
MIX IT IN THE TANK
Thanks to its miscibility and pH, the best results occur with balanced fertilisation programs, agrochemicals and efficient water management.
SPRAY
StimBlue+ is suitable for transplanting, soil and/or foliar applications.
