Description

Cycluron CAS NO 2163-69-1 is a selective, systemic herbicide belonging to the phenylurea chemical class. It matters for its pre- and post-emergence control of annual grasses and broadleaf weeds in a variety of key crops. This product is essential for agricultural professionals and formulators seeking reliable weed management solutions to protect crop yield and quality.

Application

• Selective Herbicide in Agriculture: Primarily used for the control of annual grasses and weeds in crops such as cotton, soybeans, and certain vegetables.
• Pre-emergence Weed Control: Applied to soil before weed seeds germinate, creating a protective barrier to inhibit seedling growth.
• Post-emergence Weed Control: Used to manage weeds that have already emerged, often in combination with other herbicides for broader spectrum control.
• Industrial Vegetation Management: Employed in non-crop areas like railways, utilities right-of-ways, and industrial sites for total vegetation control.
• Formulation Intermediate: Serves as a key active ingredient or technical material for manufacturers producing commercial herbicide formulations (e.g., wettable powders, soluble concentrates).
• Research & Development: Used in agrochemical research for studying herbicidal modes of action and developing new crop protection products.
