Composition:
- Active ingredient: 100 g/kg prohexadione-calcium
- Formulation: Water-soluble granules
Mode of Action:
Prohexadione-calcium inhibits gibberellin synthesis, reducing excessive shoot growth and promoting a balance between vegetative growth and fruit production. It also decreases ethylene production, reducing premature fruit drop and enhancing plant resistance to diseases.
Usage Recommendations:
Regalis® Plus can be applied once or in two stages during the growing season:
- Single application: 2.5 kg/ha during flowering (BBCH 60-69).
- Two applications: 1.5 kg/ha during flowering (BBCH 60-69) and 1.5 kg/ha at early fruit formation (BBCH 71-75).
- Maximum dose: 3 kg/ha per growing season.
Benefits of Use:
- Vegetative Growth Control: Reduces shoot length, saves pruning costs, improves canopy structure, and enhances tree productivity.
- Optimized Production: Reduces alternate bearing, improves fruit quality, ensures uniform harvests, and protects against black spot disease.
- Enhanced Tree Resistance: Protects against fire blight, increases stress tolerance, and reduces pest damage.
Application Tips:
- Compatibility: Regalis® Plus is compatible with most insecticides and fungicides, but a compatibility test is recommended before mixing. Do not mix with calcium-based products, auxins, or gibberellins.
- Application Conditions: Apply to healthy trees that are not under stress. Avoid spraying before extreme temperature changes or during severe drought conditions.
