Barclay Corrib

Advanced Fungicidal Action: Inside the Barclay Corrib Formulation

The effectiveness of 'Barclay Corrib' by Barclay Chemicals (R&D) lies in its dual-active ingredient structure, combining prochloraz and epoxiconazole. This is a strategic mix of imidazole and triazole classes, designed to maximize control while managing resistance in fungal pathogens.

Synergy of Contact and Systemic Control

• Prochloraz (Imidazole): Provides robust contact and translaminar activity. It acts as an anchor, creating a protective barrier on the plant surface and eliminating infections upon contact. It is essential for stopping the initial spread of spores.
• Epoxiconazole (Triazole): A highly systemic component. It rapidly moves through the plant's vascular system, ensuring the active substance reaches the ear and the youngest leaves, providing curative protection and long-lasting residual control.

The emulsifiable concentrate (EC) formulation is engineered for superior adhesion and rapid penetration through the waxy cuticle of the leaf. This feature is particularly vital for maintaining efficacy under fluctuating spring temperatures or humid conditions.

Performance and Application

Barclay Corrib is a versatile solution for winter and spring wheat, targeting diseases such as Septoria, powdery mildew, brown rust, and the critical Fusarium head blight. With an application rate of 1.0–2.0 L/ha, it allows for a flexible treatment program with up to two applications per season.

By integrating this systemic fungicide into your wheat protection protocol, you ensure that the plant’s photosynthetic apparatus remains intact throughout the growth stages. The combination of contact inhibition and systemic translocation provides a comprehensive defense strategy, minimizing yield loss risks caused by complex fungal infestations.
