No product lasts longer than Marengo, making it one of the least expensive program options for weed management. Products that are less expensive initially, but have a short residual, drive up both labor and product costs. Hear first-hand about the benefits of Marengo from Kevin Ganger of A. Brown Nursery.


Marengo delivers up to 8 months of selective, preemergence weed control while lowering costs.

In production ornamentals settings, Marengo:

  • Controls over 70 different weeds for fewer escapes and clean-up applications
  • Is available in two formulations
    • 18 oz. and 64 oz. Liquid Soluable Concentrate
    • 50 lb. Granular with Verge® carrier technology for uniform, virtually dust-free particle distribution.

Cost-In-Use

Growers use a variety of tools to effectively manage weeds. According to North Carolina State Extension, the cost of weed management in container nursery crops can exceed $4,000 per acre and the labor to hand weed in pots continues to be a significant expense.
