Bontima 250 EC

Premium fungal protection for winter barley crops

"Bontima 250 EC" is a professional-grade fungicide engineered for high-intensity winter barley production. Designed by Syngenta Crop Protection, this product integrates systemic and contact modes of action to address the most critical threats to cereal health. When maximizing yield potential is the primary objective, Bontima 250 EC provides the reliability needed to prevent early-season disease outbreaks.

Key advantages for field management

The formulation combines cyprodinil and isopyrazam to deliver comprehensive control over a broad spectrum of barley pathogens. Unlike basic solutions, this fungicide offers a robust curative and long-term prophylactic effect, which is crucial for modern intensive farming practices.

• Net Blotch (Pyrenophora teres): Prevents the spread of the pathogen by blocking fungal enzymes.
• Rhynchosporium (Scald): Rapid tissue penetration stops infections even after the first symptoms appear.
• Powdery Mildew: Effectively inhibits mycelium development, keeping the canopy healthy.
• Dwarf Rust: Systemic activity ensures the plant is protected from within against fungal penetration.

Operational use and field performance

Field application at a rate of 1–1.5 L/ha is recommended during the early growth stages, typically T1, to secure the plant’s health during critical tillering and stem elongation phases. With a maximum of two applications allowed per season, growers can strategically schedule their protection program to combat varying infection pressures throughout the growing year. The 30-day pre-harvest interval ensures that crop safety standards are maintained for high-quality grain production.

Manufactured under the strict quality standards of Syngenta Crop Protection AG across its global production facilities, the emulsion concentrate (EC) formulation is designed for easy mixing and compatibility in tank mixes. This ensures optimal adhesion and penetration on the leaf surface, which is essential for performance in various weather conditions.

Whether dealing with high humidity that favors net blotch or preventing rust development, Bontima 250 EC is a trusted tool for agronomists seeking predictable, high-performance disease management that supports the genetic yield potential of their winter barley varieties.
