Protect Profit Through Early Season Weed Control

Yield potential can be compromised by weed pressure early in the season. As more weeds survive glyphosate-only applications, it’s vital to implement a herbicide program that uses a residual herbicide to target weeds early on.

By mitigating early season weed pressure, growers can protect corn during critical stages of development, subsequently protecting their yield potential.

Marestail and Palmer amaranth, for example, are two of the most difficult-to-control weeds across the Corn Belt. But with the right herbicide program, they can be controlled.

  • Marestail is generally considered a winter annual weed. However, its germination pattern is starting to shift to spring and summer as a result of cropping systems and herbicide use patterns.1 Using 2.5 pints of SureStart® II herbicide preemergence followed by Durango® DMA® herbicide offers 93 percent control of marestail.2
  • Palmer amaranth started in the south. In recent years, it has been moving into Midwest fields. It has an extended emergence pattern, a rapid growth rate (up to 2 ½ inches per day) and high seed production, averaging 40,000 seeds per plant.3 Because of this growth pattern, controlling Palmer amaranth when it is small is highly important. Using 2.5 pints of SureStart II preemergence followed by Durango DMA offers 99 percent control of Palmer amaranth.2

Control high-anxiety weeds and protect profits this spring with a strong herbicide program. For more information, visit GetMoreTime.com.
