Sugar beet has a high demand for nutrients and may develop micronutrient deficiencies even in high-yielding crops. Boron is particularly important for sugar transport and root development; deficiency may impair young leaves and increase the risk of root problems. Manganese, zinc, copper and molybdenum also contribute to growth and nutrient use.
As roots and the storage root begin to develop, the source program recommends spraying Quantum Technical Crops at 1.0 L/ha, Quantum Bor Active at 0.5 L/ha and Quantum Phytophos at 1.0 L/ha. If herbicide injury appears, an additional Quantum AminoMax treatment at 0.5 L/ha is recommended 4–6 days after the herbicide application.
During active root and leaf growth, use Quantum Technical Crops at 2.0 L/ha, Quantum Bor Active at 0.5 L/ha and Quantum Phytophos at 1.0 L/ha. The source also recommends Quantum AminoMax at 0.5 L/ha after herbicide treatment to support recovery.
To support the leaf canopy and photosynthesis, the source recommends Quantum Technical Crops at 2.0 L/ha, Quantum Bor Active at 1.0 L/ha and Quantum AminoMax at 0.5 L/ha. An additional Quantum AminoMax treatment at 0.5 L/ha may be used 4–6 days after herbicide application.
The source program recommends Quantum Technical Crops at 2.0 L/ha, Quantum Bor Active at 1.0 L/ha and Quantum K36 at 2.0 L/ha. To support sugar content, it also recommends Quantum Phytophos at 1.0–1.5 L/ha and Quantum AminoMax at 0.5 L/ha 30–40 days before harvest.
Where heat or moisture stress threatens the crop, additional options listed are Quantum AminoMax at 0.5 L/ha, Quantum AquaSil at 1.0–2.0 L/ha, Quantum SeaAmin at 0.5 L/ha or Quantum Humate at 0.5–1.0 L/ha.
The source recommends combining treatments with urea at 5–15 kg/ha. Biuret must not exceed 0.8%, because a higher concentration may damage leaves; otherwise reduce the amount of urea.
