Description

Dithiopyr is a selective pre-emergence and early post-emergence herbicide belonging to the pyridine chemical class. Its primary value lies in providing superior, long-lasting control of annual grasses and broadleaf weeds in turf and ornamental settings. This compound is essential for professional turf managers, sod growers, and landscape professionals seeking to maintain high-quality turfgrass. Dithiopyr CAS NO 97886-45-8 is recognized for its efficacy and favorable environmental profile.

Application

• Turfgrass Management: Pre-emergent and early post-emergent control of crabgrass, goosegrass, and other annual grassy weeds in golf courses, sports fields, and lawns.
• Sod Production: Critical for producing clean, weed-free sod for commercial and residential installation.
• Ornamental Landscapes: Used in nurseries and landscape beds to protect ornamental plants from competing weeds.
• Professional Lawn Care: A key active ingredient in formulations for commercial lawn care service providers.
• Selective Weed Control: Effective against target weeds while being safe for established cool- and warm-season turfgrasses.
• Residential & Commercial Formulations: Serves as a technical-grade active ingredient for manufacturers of consumer and professional herbicide products.
