Scala 400SC

Why Scala 400 SC Remains the Benchmark for Rot Control

When protecting sensitive crops from fungal infections, the key challenge is not just efficacy, but the ability to perform under unpredictable weather conditions. Developed by Bayer SAS in France, this fungicide offers a unique combination of contact and systemic action.

Key Advantages

• Translaminar Activity: The active ingredient, pyrimethanil, rapidly penetrates plant tissues, ensuring resistance to rainfall washout—a major advantage over standard contact fungicides.
• Vapor Phase Action: The product exhibits a redistribution capability in the space surrounding the application site, allowing it to control pathogens even in areas where the spray coverage was not direct.
• Low-Temperature Efficiency: Unlike many systemic products that require warmth for metabolic activation, Scala 400 SC performs reliably in cooler conditions, which is critical for early-season apple scab protection.

Application Insights

This fungicide is a powerful tool against gray mold, moniliosis, and apple scab. With a short pre-harvest interval (ranging from 7 days on tomatoes to 30 days on grapes), it is ideal for use during fruit maturation, when the risk of fungal outbreaks is highest. Despite being classified as a hazard class 3 product, following the recommended regimen (up to 3 treatments per season) ensures high biological effectiveness without the risk of toxic residue accumulation.

Who is this product for? Primarily for professional growers engaged in intensive horticulture and vegetable farming, where every percent of yield counts toward the bottom line. When used in rotation, the product does not induce resistance, solidifying its position as a gold standard in fruit and berry protection programs.
