Description

Fenamidone is a modern, systemic fungicide belonging to the imidazolinone chemical class, valued for its protective and curative action against a broad spectrum of plant pathogens. Its primary value lies in providing effective, long-lasting control of oomycete diseases, particularly downy mildews, in various high-value agricultural systems. This makes it an essential tool for professional growers and agrochemical formulators focused on crop protection and yield optimization.

Application

• Primary use as a fungicide for controlling downy mildew in crops such as grapes, vegetables (e.g., lettuce, onions, cucurbits), and ornamental plants.
• Formulation into various commercial agrochemical products, including suspension concentrates (SC), wettable granules (WG), and combination products.
• Application in integrated pest management (IPM) programs due to its specific mode of action, helping to manage resistance.
• Use in professional agriculture, horticulture, and viticulture for foliar protection.
• Protection of potato crops against late blight (Phytophthora infestans).
• Control of foliar diseases in turf and certain fruit crops.
