Tonus Eco

Triple-Action Defense: The Mechanics of Tonus Eco

The efficacy of 'Tonus Eco' against oomycetes—including late blight and downy mildew—stems from its tri-component formulation, which addresses both internal systemic infections and external surface contact. By combining these modes of action, the product prevents the emergence of resistance while providing comprehensive crop coverage.

Technical Components and Their Role

• Systemic Agents (Oxadixyl and Cymoxanil): These are rapidly absorbed by plant tissues. Oxadixyl inhibits nucleic acid biosynthesis, fundamentally disrupting the metabolic pathways of the fungus. Concurrently, Cymoxanil interferes with protein and lipid synthesis, providing a crucial 'kick-back' effect that stops existing infections.
• Contact Barrier (Copper Hydroxide): This agent remains on the leaf surface, creating a protective layer. Copper ions inhibit the enzyme systems of pathogen spores before they can penetrate the plant epidermis, preventing primary outbreaks during high-humidity periods.

Operational Guidelines

Supplied as a wettable powder, the preparation requires proper agitation to ensure a consistent suspension. With an application rate of 2–2.5 kg/ha, the product forms a durable protective shield. To maintain environmental balance and avoid soil copper accumulation, the use is restricted to a maximum of three applications per season. A 30-day pre-harvest interval must be strictly observed to ensure food safety standards. Classified as a Hazard Class 3 substance, standardized personal protective equipment is required during preparation and application procedures.
