Irida

Synergy of Two Triazoles: Reliable Protection for Cereals and Oilseed Rape

«Irida» by «August-Bel» is a classic example of an effective fungicide solution that utilizes a proven combination of active ingredients: metconazole and tebuconazole. Unlike single-ingredient products, this systemic and contact fungicide provides not only curative action but also long-term preventive control against a wide spectrum of fungal pathogens.

Key Advantages

• Dual-Action Against Pathogens: The triazoles in the formulation inhibit ergosterol biosynthesis in fungal cells, effectively halting their development. Metconazole provides broad-spectrum disease control, while tebuconazole enhances the protective properties of the treatment.
• Application Versatility: «Irida» demonstrates high efficacy on winter wheat against septoria and fusarium head blight. It is also an essential tool for winter oilseed rape cultivation, effectively suppressing phoma, phomopsis, and cylindrosporium leaf spot.
• Growth Regulation: Metconazole acts as a plant growth regulator. When applied to oilseed rape in autumn, it helps the crop survive the winter better by preventing excessive growth of the apical bud.

Application and Performance

The suspension concentrate formulation ensures excellent adhesion and rapid absorption into plant tissues. However, adherence to the application schedule is critical. The maximum frequency of application is 1–2 times per season, with a dosage rate ranging from 0.5 to 1.0 L/ha. The pre-harvest interval is 30–40 days, which must be considered when scheduling harvest activities.

The product is classified as a Hazard Class 3 substance. For optimal results, application is recommended during periods of active crop growth, when the risk of powdery mildew or alternaria infection is at its highest. «Irida» is an ideal choice for farms seeking a balance between cost and efficacy, favoring time-tested fungicidal strategies for large-scale production.
