Description

Dimethenamid is a selective pre-emergence herbicide belonging to the chloroacetamide chemical class. This compound is valued for its effective control of a broad spectrum of annual grasses and broadleaf weeds in major field crops. It is a critical agrochemical input for agricultural producers and formulators seeking reliable, long-lasting residual weed management. Dimethenamid CAS NO 87674-68-8 is a key active ingredient in modern integrated pest management programs.

Application

Dimethenamid is primarily utilized as a pre-emergence herbicide in agricultural systems. Its key applications include:

• Corn (Maize) Production: For control of weeds like foxtails, barnyardgrass, and black nightshade prior to crop emergence.
• Soybean Crops: Applied pre-emergence to manage problematic weeds, including certain pigweed and lambsquarters species.
• Sunflower and Sugar Beet Cultivation: Used in selective herbicide programs to protect these crops from early-season weed competition.
• Turf and Ornamental Management: Employed in professional turf settings for pre-emergent control of grassy and broadleaf weeds.
• Agricultural Formulations: Served as a technical-grade active ingredient for the manufacture of emulsifiable concentrates (EC), suspension concentrates (SC), and other herbicide formulations.
• Soil-Applied Herbicide Programs: Often used in tank mixes or sequential programs with other herbicides to broaden the spectrum of control and manage herbicide resistance.
