COLT 690

Comprehensive protection for potatoes, tomatoes, and grapes

In high-stakes agriculture, managing fungal outbreaks like potato blight (Phytophthora) or grape mildew is a constant race against time. The «COLT 690» fungicide, manufactured by Rotam Agrochemical, provides a balanced solution by leveraging both systemic and contact action, making it a reliable tool for professional field management.

The mechanism of action

The product utilizes a potent combination of Mancozeb and Dimethomorph. This dual-action approach is critical: while the contact component provides a protective barrier on the leaf surface, the systemic component translocates within the plant tissue to stop the spread of mycelium. This makes it ideal for both preventative maintenance and tactical response during the early stages of disease development.

• Vegetables: For tomatoes and potatoes, this product is a standard in combating Alternaria and Phytophthora, preventing yield loss during high-humidity periods.
• Viticulture: Highly effective against mildew, ensuring that both existing foliage and new growth are protected.

Operational use in the field

With an application rate of 2–2.5 kg per hectare, «COLT 690» is designed for large-scale operations. When working with this wettable powder, proper mixing is essential to ensure consistent coverage. For best results, follow these practical guidelines:

Limit applications to a maximum of 3 treatments per season to manage resistance. The pre-harvest interval is 20 days; this timeline must be strictly observed, especially when handling early-ripening tomato varieties. As a Class 3 hazard level product, standard safety precautions are mandatory during preparation and application. Properly applied, this fungicide provides the necessary endurance to carry your crops through critical development phases.
