Assure® II Herbicide from AMVAC® Helps Growers Control Volunteer Corn and Grasses to Improve Yields


Growers have a tool to control volunteer corn and grasses and improve crop establishment, quality and yield. Assure II herbicide, now available from AMVAC, is a selective herbicide that controls annual and perennial grass weeds in a number of crops including canola, cotton, chickpea, dry beans, dry and succulent peas, lentil, snap bean, soybean, sugarbeet, sunflower and Enlist™ field corn. 

“AMVAC is excited to have Assure II in our portfolio of products,” said Jim Lappin, AMVAC crop marketing manager, corn and soybeans. “It’s a great tool for growers looking for a wide utility herbicide that offers postemergence grass weed control.”

In fields currently planted with Enlist corn hybrids, Assure II provides control of volunteer corn that does not include the Enlist trait (refer to product label for rate information). This includes volunteer Roundup Ready® corn (glyphosate resistant), LibertyLink® corn (glufosinate resistant) and IMI corn (imidazolinone resistant). 

For applications on Enlist corn, Assure II can be applied in V2-V6 growth stage. It controls a number of key weeds including fall panicum, giant foxtail, seeding and rhizome johnsongrass, shattercane, quackgrass, broadleaf signalgrass, goosegrass and barnyardgrass.
