Prevent Cracking and Improve Grape Quality with Parka®
Parka® enhances the grape cuticle with a clear, hydrophobic and elastic lipid bilayer that expands with the growing fruit. This protective layer seals microfractures as they form and increases cracking resistance. By stabilizing cell membranes and enhancing the plant’s natural defenses, Parka improves overall fruit quality.
Features + Benefits
- Reduces cracking damage.
- Increases fruit quality and storage ability.
- Mitigates heat stress.
- Reduces sunburn.
- Improves crop yields.
- Enhances fruit firmness.

Grapes + Kallur®
Improve First Pick Yield in Grapes with Kallur®
Kallur® is a potassium solution formulated with enhanced phospholipids to support grape color development without accelerating ripening. By influencing anthocyanin production, the plant pigments responsible for coloration, Kallur promotes earlier, more uniform color development. The result: improved overall color, first pick yield potential and packout.
Proven Benefits
- 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.
