Description

Propyzamide is a selective herbicide belonging to the benzamide chemical class, widely recognized for its pre- and early post-emergent activity against a broad spectrum of annual grasses and broadleaf weeds. Its primary value lies in providing reliable, long-lasting residual control in key agricultural and horticultural sectors, ensuring crop safety and yield protection. This product is essential for professional growers and formulators in the agriculture, turf management, and ornamental plant industries seeking effective weed management solutions.

Application

• Selective Herbicide in Agriculture: Pre-emergent and early post-emergent control of weeds in crops such as lettuce, brassicas (e.g., broccoli, cabbage), berries (e.g., strawberries, raspberries), and fruit orchards.
• Turf and Lawn Management: Used for weed suppression in professional turf settings, including golf courses, sports fields, and sod farms.
• Ornamental Horticulture: Weed control in nurseries, greenhouses, and landscape plantings for trees, shrubs, and ornamental ground covers.
• Industrial Vegetation Management: Control of unwanted vegetation in non-crop areas, including rights-of-way and utility perimeters.
• Formulation Ingredient: Serves as the active technical material for the manufacturing of various commercial herbicide formulations (e.g., wettable powders, granules, suspension concentrates).
• Research & Development: Used as a reference standard or active ingredient in agrochemical research and development of new crop protection products.
