Collis®

Collis® – Fungicide for Powdery Mildew on Grapevines

• Active Ingredients:

  • Boscalid 200 g/L
  • Kresoxim-methyl 100 g/L

• Mode of Action:
  Boscalid works by inhibiting the enzyme succinate dehydrogenase, thus blocking the mitochondrial respiration of fungi. Kresoxim-methyl interferes with essential enzymatic processes in fungal respiration. Together, they provide both systemic and translaminar protection, acting preventively and curatively when applied at the early signs of infection.

• Usage and Recommended Dosage:

  • Grapevines: Apply as a foliar spray at a concentration of 0.03–0.04% (3–4 ml in 10 L of water), corresponding to approximately 0.3–0.4 L/ha.
  • Interval: Treatments are repeated every 10–14 days, with a maximum of 3 applications per season.
  • Application Timing: The first application should be done preventively before infection occurs (typically in the pre-flowering stage, BBCH 53–55).

• Precautions:

  • Avoid direct contact with skin and eyes; use appropriate protective gear.
  • Do not apply the product when rain is imminent to ensure optimal adhesion.

• Pre-Harvest Interval:
  28 days for grapevines.
