DICAMBA VS. 2, 4-D SOIL ACTIVITY

Herbicide and Weed Management Briefs

Author: Jim Schwartz

There is a difference between residual activity and soil activity. Residual herbicides typically suppress weeds from germinating for four to five weeks. Examples include: Authority®, Valor®, Fierce®, and Zidua®. Products that have soil activity can suppress weeds for 7 to 14 days but will not have enough activity to prevent future flushes of weeds later in the season. Engenia® and XtendiMax® can suppress the germination of small-seeded broadleaf weeds such as waterhemp, but we must pair Engenia and XtendiMax to achieve satisfactory weed control.

Early Burndown Options

Author: Austin Scott

God willing, planters will be rolling through fields within the next four to five weeks. If you haven’t already, now is the time to start thinking about burndown options. We’ve had a very mild winter (as you can tell by the size of our wheat!) and many winter annuals have grown much larger than usual. This should be taken into consideration when thinking about those hard-to-control winter weeds like Italian ryegrass and marestail.

XtendiMax™ is Now Labeled for Use...

Author: Luke Schulte

By now many of you are probably aware that the EPA has approved the use of the herbicide XtendiMax™ with VaporGrip™ technology for in-crop use in dicamba tolerant soybeans. The Roundup Ready 2 Xtend® soybeans will have tolerance to both glyphosate as well as dicamba. Currently, the XtendiMax label only has a two-year registration. The EPA has reserved the right to rescind the label if they feel the product is being misused, is having a negative impact on the environment and general public impact, or is having a high number of off-target incidents.
