Scala 400 SC c.a.

The Technical Edge of Pyrimethanil

At the core of the "Scala 400 SC" fungicide is Pyrimethanil (400 g/L), an anilinopyrimidine active ingredient that fundamentally alters the fungal control landscape. Unlike standard products that merely inhibit respiration, the Bayer-formulated Scala disrupts the secretion of hydrolytic enzymes by the pathogen. By blocking the biosynthesis of methionine, it effectively starves the fungus of the amino acids required for survival, rendering it unable to penetrate plant cell walls.

Key Technical Advantages

Scala 400 SC is engineered for versatility and resilience in challenging environmental conditions:

• Low-Temperature Performance: One of the most significant technical attributes is its ability to remain active at temperatures as low as +5°C. This makes it an essential tool for early-season scab control in apple orchards when conventional chemistry often fails.
• Gas Phase Activity: The chemical properties of the active ingredient allow for a degree of vapor redistribution. This ensures that the product reaches areas not directly touched by the spray nozzle, providing a more uniform protective layer across dense foliage and fruit clusters.

Application and Integration

Formulated as a Suspension Concentrate (SC), Scala offers superior stability and ease of mixing. With a recommended rate of 0.75–1.2 L/ha, it provides a balance between cost-effectiveness and high biological efficiency against Botrytis (gray mold) and Venturia (scab). As a systemic fungicide, it is rapidly absorbed into the plant cuticle, providing robust rainfastness. Adhering to a regimen of 2–3 applications with a 21–30 day pre-harvest interval ensures both a clean crop and compliance with international food safety standards.
