Professional Oidium management with Collis SC

Controlling Oidium in vineyards requires more than just contact surface protection; it demands systemic power and long-lasting residual efficacy. Collis SC, developed by BASF SE (Germany), is a specialized fungicide designed to tackle powdery mildew by combining two potent active ingredients: boscalid (carboxamides) and kresoxim-methyl (strobilurins).

Synergistic protection mechanism

The core strength of Collis SC lies in its multi-site mode of action. By inhibiting the energy production and respiratory processes of the fungus, it effectively prevents spore germination and mycelial development. This makes it a critical tool in integrated pest management programs, especially for preventing resistance buildup.

• Systemic action: The product is absorbed into the plant tissues, providing robust protection for foliage and developing grape clusters.
• Flexible dosage: With a recommended application rate of 0.4–0.6 L/ha, growers can adjust usage based on the actual disease pressure in their vineyard.
• Crop health: Beyond disease control, the formulation supports vine vitality, contributing to better yield consistency and fruit quality.

Operational guidelines

Collis SC is classified as a Hazard Class 3 product, requiring standard safety precautions during mixing and application. To ensure optimal performance and residue compliance, growers are limited to a maximum of 3 applications per season. Furthermore, a pre-harvest interval (PHI) of 30 days must be strictly observed. For vineyard managers aiming for high-quality production, Collis SC remains one of the most reliable German-engineered tools available for securing a healthy harvest.
