OHP Improves Marengo G Formulation

OHP, Inc. announced the availability of the new and improved Marengo granular herbicide formulation. The new formulation of Marengo G allows for easier application and provides the same effective performance.

“We’re pleased with the initial response and market acceptance we saw with the original Marengo G formulation,” said Dan Stahl, OHP vice president of marketing and business development. “We feel Marengo G produced on the new granule will result in even greater market penetration.”

Marengo G offers effective, long-term pre-emergent control of both broadleaf and grassy weeds with little effect on desirable plants. The product doesn’t volatilize and doesn’t move in the soil once it’s watered-in after application. Marengo G can be applied over the top of containers in nurseries and may be applied in hoop, shade and lath houses.


The new Marengo G formulation, with its active ingredient indaziflam, is produced on granules that utilize the proprietary Verge technology, resulting in larger, heavier and more uniform particles that offer several advantages for users:

• Reduced dust for less applicator exposure
• More uniform coverage
• More accurate, on-target applications, even in breezier conditions
• Less chance for plant injury, as the heavier particle rolls freely off of plant surfaces

The new formulation looks and handles much like Biathlon, another OHP herbicide, said David Barcel, OHP senior technical manager for herbicides and PGRs.

“Both Marengo G and Biathlon are produced utilizing the Verge granule technology,” said David. “We have received nothing but positive feedback from Biathlon users and anticipate the same with Marengo G.”
