START CLEAN, STAY CLEAN
Deploy multiple sites of action in a layered residual program for superior soybean weed control.
OVERLAPPING RESIDUAL HERBICIDE ACTION PLAN:
-
Start with a strong preemergence residual herbicide, such as an Authority® brand herbicide.
-
Follow-up 14 to no more than 28 days later with an overlapping residual, Anthem® MAXX herbicide.
WHY LAYER RESIDUAL HERBICIDES?
- Increased herbicide diversity.
- Reduction in selection pressure.
- Improved control of weed spectrum.
- Fewer weed escapes.
- Reduction in weed competition.

Chart:
A two-pass, overlapping, residual herbicide program leveraging Anthem MAXX herbicide and Authority Edge herbicide achieved excellent grass and waterhemp control in a 2019 Iowa State University trial against a single preemergence application of multiple well-known names in weed control. This protocol demonstrated just how important a postemergence application is for achieving excellent control of tough grasses.

These university trials achieved short- and long-term benefits when leveraging an overlapping residual approach for waterhemp control. In all three trials, residual herbicides from FMC were utilized PRE and POST. Weed count, weed biomass/weight and soybean yield were measured to indicate program results.
