Copper-based protection: mechanism of action

"Sumish Bordo, VP" is a classic contact fungicide designed to create a protective barrier against fungal pathogens. Its efficacy stems from the properties of copper sulfate, which, when properly applied, interferes with the respiratory enzyme systems of fungi. Unlike systemic products, this contact formulation does not move within the plant tissues; instead, it provides a residual shield on the surface of leaves, stems, and fruits, preventing spore germination upon contact.

Technical scope and target pathogens

The formulation in the form of a wettable powder ensures uniform distribution across the plant’s surface. It is highly effective against a variety of diseases that threaten crop yields, including:

• Orchard crops (Apple, Apricot): Essential in the management of scab and moniliosis.
• Vegetables (Tomato): A critical tool for controlling late blight and macrosporiosis.
• Vineyards: Provides robust protection against downy mildew (mildew).

Usage and Application Guidelines

Provided by "Agrokhimpak" and "Agrokhimmarket" (Ukraine), this fungicide requires precise application techniques to maximize its protective potential. Because it acts strictly upon contact, high-quality coverage is mandatory to eliminate infection entry points.

• Application frequency: Depending on infection pressure, 3 to 6 treatments per season are permitted.
• Safety and intervals: Classified under hazard class 3, the product requires strict adherence to pre-harvest intervals, which range from 20 to 30 days.

When planning your crop protection strategy, keep in mind that copper-based products are most effective as preventative measures. By creating a physical and chemical barrier before pathogens proliferate, growers can significantly reduce the risk of extensive disease development. Always ensure that the equipment used provides a fine, uniform mist for total leaf coverage.
