US: Granular formulation of OHP's Marengo now available

OHP, Inc. has followed up the launch of Marengo liquid pre-emergent herbicide with the introduction of Marengo G, a granular formulation with the same effective active ingredient, indaziflam.

Marengo G offers many of the same features as Marengo SC including consistent plant safety, broad-spectrum weed control, and long-term residual. Its label allows for application to containers in nurseries, and hoop and shade houses.

Marengo G offers effective, long-term selective pre-emergent control of both broadleaf and grassy weeds with little effect on desirable plant species. The product does not volatilize and does not move in soil once watered-in after application.

Marengo contains the first active ingredient from MOA (Mode of Action) Group 29. The active ingredient prevents weed seed germination by inhibiting cellulose biosynthesis.

“We’re pleased to introduce a granular version of Marengo to the market after the successful launch of Marengo liquid,” notes Terry Higgins, OHP vice president and general manager. “Marengo G features all the benefits of indaziflam in an easy-to-apply granular formulation for over-the-top applications.”

California and New York State registrations are pending.
