Description

Penthiopyrad is a modern, broad-spectrum succinate dehydrogenase inhibitor (SDHI) fungicide belonging to the carboxamide chemical class. It is highly effective against a wide range of fungal pathogens, offering both protective and curative activity. This product is essential for agricultural professionals and formulators seeking reliable disease control in key crops such as fruits, vegetables, and turf.

Application

• Agricultural Fungicide: Primary use in controlling powdery mildew, scab, rust, and other foliar diseases in pome fruits (apples, pears), stone fruits, and berries.
• Vegetable Crop Protection: Applied to protect cucurbits, tomatoes, potatoes, and leafy vegetables from major fungal infections.
• Turf and Ornamental Management: Used in professional turf management (golf courses, sports fields) and for ornamental plants to maintain plant health and aesthetics.
• Seed Treatment: Formulated for treating seeds to protect against soil-borne and early-season seed-borne diseases.
• Fungicide Formulations: Serves as a key technical active ingredient (TC/TK) for the manufacturing of suspension concentrates (SC), wettable powders (WP), and other commercial fungicide formulations.
• Resistance Management: An important tool in integrated pest management (IPM) and fungicide resistance management programs due to its unique mode of action.
