Description

Neburon CAS NO 555-37-3 is a selective phenylurea herbicide known for its pre-emergent and early post-emergent activity against a broad spectrum of annual grasses and broadleaf weeds. Its primary value lies in providing effective, long-lasting residual weed control in key agricultural and non-crop settings. This product is essential for professionals in the agrochemical industry, particularly formulators developing selective herbicide solutions for crops like asparagus, strawberries, and ornamentals, as well as for industrial vegetation management.

Application

• Selective Crop Protection: Used as a pre-emergent herbicide in asparagus, strawberries, and certain ornamental nurseries.
• Non-Crop Area Management: Effective for total vegetation control on industrial sites, railways, and utility rights-of-way.
• Turf Management: Applied in certain turfgrass settings for controlling problematic weeds.
• Agricultural Formulations: Serves as a key active ingredient in the manufacture of wettable powder (WP) and granular (GR) herbicide formulations.
• Soil Persistence: Valued for its residual activity, providing season-long control from a single application.
• Research & Development: Used as a reference standard or intermediate in agrochemical research and synthesis.
