treflan herbicide Andersons Treflan Herbicide DG 5 Percent Granular– Seed World

Andersons 5% Treflan Herbicide DG is a granular, pre-emergent weed preventer designed for ornamental landscapes, professional nurseries, and container plantings. With 5% trifluralin, this soil-applied product targets weed seeds before they germinate, helping you maintain clean beds and pots without harming established greenery when used as directed.

What makes it different

• Granular DG formulation provides even distribution, reducing drift and gaps that can occur with liquid pre-emergents.
• Focused on established ornamental systems—beds, borders, containers, and nursery flats—where keeping roots undisturbed matters most.
• Specifically dosed for large-scale coverage—a 40-lb bag delivers about 22,000 sq ft of protection at the 1.8 lb per 1,000 sq ft rate, making it cost-effective for sizeable landscapes.
• Selective protection against annual grasses and many annual broadleaf weeds while generally safe for established ornamentals when applied per label directions.

How to use

• Apply to dry soil at the recommended rate of 1.8 lbs per 1,000 sq ft for even coverage. Use a spreader for uniform distribution in larger beds or stick to hand application for containers and small areas.
• Water in thoroughly after application to activate the herbicide and move it into the soil where weed seeds germinate.
• Avoid disturbing soil after application and don’t apply to areas you plan to seed or transplant in the near term.
• Reapply according to label directions with the seasons and your weed pressure, ensuring you maintain a protective barrier over time.

Ideal use cases

• New or refreshed ornamental beds where weed pressure is high and you want long-lasting, soil-based prevention.
• Container plantings and potting areas in nurseries or commercial settings where consistent weed control is essential.
• Established landscapes around shrubs and perennials where you want to reduce annual grasses and broadleaf weed emergence without disturbing roots.
