OHP Launches New HerbicideSource: OHP Inc.

OHP recently introduced its new Marengo herbicide for the production ornamental market.

OHP Inc. announced the introduction of Marengo Herbicide to growers in the production ornamental market. Marengo has received its federal U.S. Environmental Protection Agency registration and is undergoing the state registration process.

Marengo, with the new active ingredient indaziflam, is a selective pre-emergent herbicide that offers long-term residual control of both grassy and broadleaf leaves.

Marengo contains the first active ingredient from MOA (Mode of Action) Group 29. The active ingredient prevents weed seed germination by inhibiting cellulose biosynthesis. Marengo does not move once applied to the soil and does not volatilize.

Marengo is registered for use on production ornamentals grown in outdoor nurseries, as well as on conifers, Christmas trees, and ornamental production sites and hardscapes. Marengo is labeled for use in shade houses and hoop houses as well.

“Marengo offers extended broad-spectrum weed control of up to eight months in nurseries but also in extended use sites such as hardscapes and hoop houses,” notes Dave Barcel, OHP senior technical manager. “It’s extremely active at low use rates.”

Marengo will be packaged in one-half gallons, packed four to a case.
