Collis®

Professional Oidium control: why «Collis®» is a staple for vineyards

Every grape grower knows that oidium is relentless. When managing large vineyards, you cannot afford to gamble with subpar protection. I have been using «Collis®» by BASF Agro B.V. for several seasons, and it remains one of the most reliable tools in my cabinet. What stands out is its formulation — a nano-emulsion concentrate that provides excellent coverage, ensuring the product reaches every corner of the canopy and dense clusters where the fungus usually hides.

Dual-Action Power

The strength of «Collis®» lies in the synergy between Boscalid and Kresoxim-methyl. This combination provides both systemic and contact activity. In practice, this means it acts as a barrier that prevents spore germination while simultaneously stopping existing infections from spreading. At a dose of 0.4–0.8 l/ha, it works consistently regardless of the pressure, which is crucial during high-risk growth stages.

Field Application Insights

• Ease of Use: The nano-emulsion formulation is highly stable. I have never encountered clogged nozzles, which keeps the spraying equipment running smoothly and minimizes downtime during peak season.
• Application Strategy: With a limit of 3 applications per season, it is easy to build into a spray program. Just remember the 30-day pre-harvest interval to ensure clean fruit.
• Quality Assurance: Whether the batch comes from France, Italy, Germany, or the USA, the quality remains consistent. That reliability is what I value most when choosing crop protection products.

For me, using «Collis®» is about risk management. It is a class 3 product that requires standard safety protocols, but its performance is predictable and robust. If you need a fungicide that does exactly what it promises, this is an excellent choice for modern viticulture.
