Scala 400 SC Fungicide 5L – Preventative Botrytis & Disease Control

Foliar Fungicide for Botrytis & Crop Disease

Scala 400 SC Fungicide is a foliar fungicide containing 400g/L pyrimethanil, formulated to provide preventative control of grey mould caused by Botrytis cinerea. The 400 SC formulation was registered for use in grapevines, strawberries and tolerant ornamental species. It also provided control of yellow Sigatoka, leaf speckle and cordana leaf spot in bananas.

Scala has translaminar properties, allowing the active ingredient to penetrate green plant tissue and provide protection against latent infections. Its Group 9 activity makes it a useful component of a planned fungicide rotation.

Important: Bayer's current Australian product information states that Scala 600 SC replaces the original Scala 400 SC formulation. Always check the current Australian label before application, particularly where older 400 SC stock is being used.

Diseases Controlled

Scala 400 SC was registered for control of grey mould (Botrytis cinerea) in grapevines, strawberries and tolerant ornamental species. It was also registered for yellow Sigatoka, leaf speckle and cordana leaf spot in bananas.

For grapevines, Bayer's product information highlights its use as part of a preventative Botrytis management program, particularly around important flowering stages.

How Scala 400 SC Works

Pyrimethanil acts on fungal processes involved in amino acid and protein synthesis. Scala also penetrates plant tissue, providing translaminar protection rather than relying solely on a surface deposit.

Because disease resistance can develop with repeated use of the same chemistry, Scala should be incorporated into a suitable resistance management program and alternated with fungicides from different chemical groups where required.

Application & Dosage

The registered 400 SC label specified 200mL per 100L of water for dilute spraying in grapevines, with crop-specific rates and application requirements varying between registered uses.

Application should provide thorough and even coverage of the relevant plant tissue, particularly flowers and bunches in grapevines. Always use the current applicable Australian label for the exact crop, rate, timing and withholding requirements.
