Description

Pencycuron is a phenylurea fungicide belonging to the chemical class of acylalanines, recognized for its specific and protective action against soil-borne and seed-borne diseases. Its primary value lies in its effectiveness against Rhizoctonia solani and related pathogens, offering a reliable solution for crop protection programs. This product is essential for agricultural formulators and producers seeking to develop fungicidal treatments for potatoes, rice, and various vegetable crops.

Application

• Seed Treatment: Used as a protective seed dressing to control damping-off and root rot caused by Rhizoctonia solani in potatoes, rice, and sugar beets.
• Soil Application: Applied to soil for the management of soil-borne fungal pathogens in vegetable crops and ornamental plants.
• Tuber Treatment: Specifically effective for the control of black scurf and stem canker on potato seed tubers.
• Rice Crop Protection: Formulated for the prevention of sheath blight in paddy rice cultivation.
• Agricultural Formulations: Serves as a key technical active ingredient (TC) in the manufacture of wettable powders (WP), suspension concentrates (SC), and other fungicidal formulations.
• Turf and Ornamentals: Employed in professional turf management and for the protection of ornamental plants against specific fungal diseases.
