Impera Gold 490 SC

Synergy in Action: How Impera Gold 490 EC Works

The efficacy of Impera Gold 490 EC relies on a precisely calibrated blend of two active ingredients belonging to distinct chemical classes: prochloraz (imidazoles) and propiconazole (triazoles). This pairing ensures not only a wide spectrum of disease control but also a dual-action approach to pathogen suppression within the plant tissue.

Prochloraz functions primarily as a contact fungicide. It acts as a disinfectant, creating a protective barrier on the leaf surface and, crucially, on the wheat ear, effectively preventing spore germination. Propiconazole complements this by providing strong systemic activity; it is rapidly absorbed and translocated throughout the plant’s vascular system, offering both preventive and curative properties against established infections.

Technical Specifications and Application Benefits

• Target Crops: Specifically formulated for winter wheat and winter barley, addressing the challenges of intensive cereal cultivation.
• Pathogen Control: Highly effective against leaf and ear diseases, including Septoria, brown rust, Fusarium head blight, net blotch in barley, and Rhynchosporium.
• Formulation: The emulsifiable concentrate (EC) formulation ensures high stability in the tank mix and excellent adhesion, which enhances penetration even in challenging field conditions.

Operational Guidelines

For optimal field performance, the application rate is set at 1–1.5 liters per hectare. The product allows for a maximum of two applications per season, with a 30-day pre-harvest interval (PHI). Developed by Makhteshim Chemical Works Ltd., a member of the Makhteshim Agan Industries group, this fungicide is engineered to maintain chemical stability under varying climatic conditions, making it an essential component for high-yield cereal management.

By inhibiting ergosterol synthesis within the fungal cell walls, the dual-action formula disrupts the integrity of the pathogen membrane, leading to its rapid inhibition. This technical approach effectively reduces the incidence of powdery mildew and other major fungal threats, ensuring crop vitality throughout the growth cycle.
