Description

Pendimethalin is a selective pre-emergence dinitroaniline herbicide. It is valued for its long-lasting residual activity and effectiveness against a broad spectrum of annual grasses and broadleaf weeds. This product is essential for agricultural professionals and formulators seeking reliable, cost-effective weed control solutions. Pendimethalin CAS NO 40487-42-1 is a cornerstone active ingredient in the production of crop protection products for global agriculture.

Application

• Pre-emergence Herbicide in Agriculture: Primary use for controlling weeds in crops such as cotton, soybeans, corn, and various vegetables before weed emergence.
• Orchard and Vineyard Management: Applied for weed suppression in tree fruit, nut, and grape vineyards to reduce competition for water and nutrients.
• Turf and Ornamental Care: Used in professional turf management (e.g., golf courses, lawns) and ornamental plant production for selective weed control.
• Industrial Vegetation Management: Employed in non-crop areas like roadsides, fence lines, and utility rights-of-way for long-term vegetation suppression.
• Formulation Intermediate: Serves as the key active ingredient for manufacturing various commercial herbicide formulations, including emulsifiable concentrates (EC) and granular products.
