Regalis

Mechanism of Action: Prohexadione-calcium

The core technology behind «Regalis» is the active ingredient prohexadione-calcium, which fundamentally alters the physiological profile of fruit trees. By inhibiting gibberellin biosynthesis at late stages, the product slows down terminal shoot growth without causing metabolic stress. This shift in energy allocation redirects the tree's resources from excessive vegetative growth to flower bud differentiation and fruit development.

Managing Fire Blight (Erwinia amylovora)

Beyond its growth-regulating properties, «Regalis» provides a distinct physiological advantage in plant health. The application triggers a change in flavonoid metabolism, stimulating the production of compounds that impede the penetration and development of the fire blight pathogen. By reinforcing cell walls, the treatment creates a systemic barrier, making the host tissue less hospitable to infection. This makes the product a cornerstone in integrated pest management strategies.

Operational Advantages

• Formulation: Water-dispersible granules ensure excellent solubility and physical stability within the spray tank, preventing nozzle clogging.
• Application Strategy: Applied as a foliar spray during intensive shoot growth, it provides precise control over the tree architecture.
• Orchard Management: By reducing internode length, the product increases canopy light penetration. This is essential for fruit coloration and facilitates easier winter pruning.

Produced by BASF SE (Ludwigshafen, Germany), this product adheres to stringent safety standards (Hazard Class 3). Its efficacy is directly proportional to the precise application rate, making it an essential tool for commercial growers aiming for yield quality and orchard longevity.
