Pirus 400 CS

Professional crop protection for orchards and vineyards

When managing intensive apple orchards and vineyards, controlling scab and gray mold is a constant challenge. Pirus 400 SC from the Belgian company Agriphar S.A. has become our go-to solution for rapid disease control under fluctuating weather conditions. Its contact mode of action combined with fast tissue penetration is what delivers consistent results in the field.

Practical application and dosage

Over years of field trials, we have optimized our usage protocol. A key advantage is the product's stable performance at low temperatures, which is crucial during early spring blooming when other fungicides tend to lose efficacy. The dosage is straightforward: 0.5–1.0 l/ha provides uniform coverage without excessive chemical load.

• Cold-weather performance: The active ingredient, pyrimethanil, remains highly active even at temperatures as low as +5°C.
• Resistance management: The limit of 3 applications per season makes it an ideal component for anti-resistance integrated pest management (IPM) programs.
• Pre-harvest interval: A 21-day wait period before harvest offers enough flexibility to plan your logistics effectively.

Operational notes

The suspension concentrate formulation is highly user-friendly; it doses easily and mixes perfectly in the spray tank without leaving residues or clogging nozzles. We haven't observed any phytotoxicity issues, even when applying near the upper end of the recommended dosage. As a class 3 hazardous product, standard personal protective equipment (PPE) is sufficient to ensure operator safety during field application.

Crucially, Pirus 400 SC is a professional-grade tool. It requires precise adherence to the application schedule and proper calibration of spraying equipment to ensure even surface coverage. When used correctly, it yields healthy, high-quality fruit, significantly reducing the risk of rot and scab damage at harvest.
