Scout, Identify and Plan to Contain Troublesome and Resistant Weeds

Scouting fields can help you make profitable decisions for next year. Take note of weed escapes and update weed management plans to control them. Weeds such as waterhemp, marestail, giant ragweed, Palmer amaranth and others may require a change in your herbicide program to improve weed control and limit the opportunities for these weeds to develop resistance to effective herbicides.

The Enlist™ weed control system works with a herbicide program approach that can take advantage of multiple modes of action to control tough weeds and curb opportunities for resistance.

Residual herbicides are key to start the season right. They help control weeds early in the season, letting the crop get off to a good start, which helps maximize yield potential. In addition, they are the first step in implementing multiple modes of action on the acre. Farmers can follow residual treatments with postemergence applications of Enlist Duo® herbicide and/or Enlist One® with qualified tank-mix partners.

Enlist Duo is a convenient combination of 2,4-D choline and glyphosate. Enlist One is a straight-goods 2,4-D choline that offers additional tank-mix flexibility. Farmers who plant Enlist corn also can use FOP herbicides for an additional effective mode of action on unwanted grasses or volunteer corn without the Enlist trait. Meanwhile, Enlist E3® soybeans are tolerant to glufosinate, which can be used in a tank mix with Enlist One herbicide.

It’s important to scout fields regularly all season long and watch for weed escapes. Resistant weeds often appear as patches in fields. Identifying these areas early helps prevent widespread distribution of seeds from the resistant population. If live weeds are growing next to dead weeds and they are of similar size, the surviving weeds may be resistant to the herbicide used in the field.

When you identify resistant weeds, try to control them as quickly as possible, preferably before harvest, when the combine may spread them throughout a larger area of the field. Then develop your weed management plan for the next year to apply effective herbicides that can stop these resistant weeds from further development. You can take advantage of the Enlist weed control system to help curb the spread of glyphosate-resistant and other tough weeds.
