Description

Monolinuron is a selective phenylurea herbicide belonging to the chemical class of substituted ureas. This compound is valued for its pre- and early post-emergence control of annual broadleaf and grassy weeds in various crops. It is primarily utilized in the agricultural and horticultural sectors by formulators and producers of crop protection products. Monolinuron CAS NO 1746-81-2 offers a reliable solution for integrated weed management programs.

Application

• Selective Herbicide in Agriculture: Pre- and early post-emergence control of weeds in crops such as potatoes, carrots, and asparagus.
• Horticultural Weed Management: Used in fruit orchards and ornamental plant nurseries for maintaining clean cultivation beds.
• Industrial Vegetation Control: Component in non-crop area herbicides for managing vegetation along railways, fence lines, and industrial sites.
• Formulation Ingredient: Active ingredient in the manufacture of emulsifiable concentrates (EC) and wettable powders (WP) for professional and agricultural use.
• Research & Development: Used as an analytical reference standard and in agrochemical research for studying urea herbicide modes of action.
