Bordeo Izavro 20 z.p.

The Copper Shield Technology: How Bordo Izavro 20 Works

The efficacy of 'Bordo Izavro 20 z.p.' lies in its precise formulation of copper sulfate, refined through Italian manufacturing standards by Isagro, Milan. As a contact fungicide, its primary function is to prevent pathogen penetration by creating an impenetrable barrier on the surface of plant tissues.

Technical Mechanism

The copper ions in the formulation act as multi-site inhibitors, effectively denaturing the proteins and enzymes within fungal spores and bacteria. Because it is applied as a wettable powder, the preparation forms a highly stable suspension. This ensures that the active ingredient covers the leaf surface evenly, even on hydrophobic waxes or uneven textures, which is essential for consistent protection against diseases like scab or mildew.

Key Applications and Efficacy

• Apple: Exceptional for managing scab (Venturia inaequalis), especially during high-humidity periods that trigger sporulation.
• Grapevine: Prevents mildew outbreaks by blocking zoospores from establishing themselves on leaves and berries.
• Peach: Critical for early-season control of leaf curl and moniliosis, neutralizing overwintering inoculum before it can cause structural damage.

Falling under the 3rd hazard class, the product requires standard handling procedures. The quality of the micronized particles in this powder prevents nozzle clogging, ensuring that the spraying process remains efficient and that the dosage application is accurate across the entire orchard or vineyard. Its contact-only mode of action makes it a cornerstone for resistance management programs in sustainable agriculture.
