Part 4: Multiple Modes of Action Control Tough Weeds

November 18, 2016

In this edition, growers in Iowa and Minnesota share their experiences with Acuron® and Acuron Flexi corn herbicides in 2016. Iowa growers singled out waterhemp as their toughest weed to control, while Minnesota growers cited both waterhemp and giant ragweed.

Extremely wet conditions in Minnesota in August made in-field photography impossible, but growers there were happy with the performance of both Acuron and Acuron Flexi. Mike Anders, a grower and retailer from Nerstrand, Minnesota, said the tank mix flexibility and geographic flexibility in Acuron Flexi are especially beneficial to him since the product does not contain atrazine.

Here’s a recap:

Hayward, Minnesota: Wet conditions prevented in-field photos, but grower and retailer Tim Westrum reported that Acuron performed well against his two toughest weeds: giant ragweed and waterhemp. A foundation rate of Acuron was applied pre-emerge and followed at a later date with an application of Halex® GT.
