OHP introduces granular Marengo herbicide
September 16, 2013
OHP, Inc. has followed up its successful 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 production ornamental growers many of the same features as Marengo SC including consistent plant safety, broad-spectrum weed control, and long-term residual.
The Marengo G label allows for application to containers in nurseries, and hoop and shade houses.
“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.”
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.
“With the new formulation, growers in container and field nurseries may now use the product for over-the-top applications,” says Dan Stahl, OHP vice president of marketing and business development.
Marengo contains the first active ingredient from MOA (Mode of Action) Group 29. The active ingredient prevents weed seed germination by inhibiting cellulose biosynthesis.
California and New York state registrations are pending.

Prevention and Management of Boxwood Blight
January 28, 2013
by Kelly Ivors, Extension Plant Pathologist, Dept. of Plant Pathology, NC State University
This disease can significantly impact the appearance and aesthetics of boxwood because the foliage typically becomes blighted and drops from the plant. Symptoms of box blight include: dark‐ or light‐brown, circular leaf spots often with darker margins; dark stem cankers or black ‘streaks’ on stems; straw‐ to bronze‐ colored, blighted foliage; and leaf drop. Leaf spots may grow together to eventually cover the entire leaf (see pictures). In container boxwood, sometimes only the lower foliage and stems become infected, leaving the tops green and making the plant appear top‐heavy.On large field‐grown or landscape plants only one section of the plant closest to the ground on the shaded side will be blighted.

OHP launches new Marengo® herbicide
December 18, 2012
OHP Inc. is proud to announce the introduction of Marengo® Herbicide to growers in the production ornamental market.
Marengo has received its federal EPA registration and is undergoing the state registration process.
Marengo, with the exciting new active ingredient indaziflam, is a selective pre-emergent herbicide that offers long-term residual control of both grassy and broadleaf leaves.
“We are thrilled to add Marengo to our expanding herbicide portfolio,” notes Dan Stahl, OHP vice president of marketing and business development. “Marengo offers unparalleled residual control of many hard-to-control weeds with impressive plant safety.”
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 use rates range from 7.5 to 18.5 fl.oz. per acre depending on soil type and conditions. It performs best when applied to bare ground or mixed with a post-emergent herbicide to eliminate existing weeds.
Marengo should be applied as a broadcast spray over ground areas and as a directed spray for field grown ornamentals. Fall applications have shown excellent weed control through the following spring season.
Marengo will be packaged in one-half gallons, packed 4 to a case.
