Cherry + Kallur®
Enhance Cherry Color and Packout Potential with Kallur®
Kallur® is a potassium solution formulated with enhanced phospholipids to support cherry color development without accelerating ripening. By influencing anthocyanin production, the plant pigments responsible for red coloration, Kallur promotes earlier, more uniform color development. The result: improved packout quality and increased first pick potential.
Proven Results
- Improves coloring without accelerating ripeness.
- Increases first pick yield potential, potentially eliminating harvest trips.
- Earlier and more uniform fruit color.
- Easily tank mixed for stress-free applications.
- Excellent complement to the Parka program.
