Description

Dimefuron CAS NO 34205-21-5 is a selective phenylurea herbicide belonging to the chemical class of substituted ureas. This compound is valued for its effective pre- and early post-emergence control of a broad spectrum of annual grasses and broadleaf weeds in various crops. It is primarily utilized in agricultural and horticultural sectors where reliable weed management is critical for crop yield and quality. Our supply ensures consistent quality and reliable availability for industrial-scale applications.

Application

• Pre-emergence Herbicide in Cereals: Applied to soil for controlling weeds in wheat, barley, and other cereal crops before weed seedlings emerge.
• Early Post-emergence Weed Control: Used in the early growth stages of crops like corn and soybeans to manage competing vegetation.
• Industrial Vegetation Management: Employed in non-crop areas such as railways, industrial sites, and utilities for total vegetation control.
• Orchard and Vineyard Maintenance: Applied in tree fruit and grape vineyards to maintain clean strips under trees and vines, minimizing competition for water and nutrients.
• Formulation Intermediate: Serves as a key active ingredient in the manufacturing of professional agricultural herbicide formulations (e.g., wettable powders, suspension concentrates).
• Research & Development: Used in agrochemical R&D for studying herbicidal activity and developing new crop protection solutions.
