Securing Cereal Yields: Practical Use of 'Virtuoz' Fungicide

Maintaining a healthy flag leaf is the cornerstone of high-yield winter wheat production. The systemic fungicide 'Virtuoz' by Nertus offers a robust solution for cereal growers operating under intensive cultivation programs. By combining propyconazole and cyproconazole, this product provides a dual-action defense mechanism against a broad array of fungal pathogens.

Targeting Key Cereal Diseases

Agronomists incorporate 'Virtuoz' into their spray programs to combat diseases that significantly degrade grain quality and total yield. The fungicide is highly effective against:

• Septoria leaf and glume blotch;
• Stem and leaf rust;
• Cercosporella (eyespot) and Fusarium;
• Various leaf spots and Alternaria.

The systemic nature of the formula ensures that the active ingredients are rapidly absorbed by the plant. This allows for both curative action on existing infections and the creation of a protective barrier for new plant growth, shielding the crop during critical development stages.

Application Guidelines for Field Operations

'Virtuoz' is formulated as an emulsifiable concentrate, facilitating easy integration into tank mixes. For optimal control, the application rate is up to 0.5 L/ha, depending on the severity of the pressure in the field.

Operational Parameters:

• Maximum number of applications: 2 per season.
• Pre-harvest interval (PHI): 30 days.
• Hazard class: 2 (standard precautions apply).

Best results are typically achieved when the product is applied from the stem elongation stage through to the onset of heading. By utilizing this triazole-based fungicide, farmers can effectively stop the progression of fungal infections, ensuring the canopy remains healthy throughout the grain-filling period.
