Navigating Weeds within a Compressed Planting Window

Categories: PLANTING, SOYBEANS

​​​​​​​
Planting corn and soybeans simultaneously creates a challenging herbicide application environment. Add in windy days, and there is a risk that residual chemistry will not be applied prior to planting and/or emergence.

When soybean fields have been planted prior to a residual product application, remain diligent to overlapping residuals, even if you have to call an “audible” at the line of scrimmage. Considering the calendar date and the length of time waterhemp will germinate drives this response. Below are several examples of how residual herbicides may be used when soybeans emerge before herbicide application.

ROUNDUP READY 2 YIELD® SOYBEANS

Situation

Herbicide Solution

  • Soybeans have emerged
  • Waterhemp has not emerged
  • No giant ragweed

Apply Sequence® (Dual Magnum® + glyphosate) followed by Prefix® + glyphosate 21 to 28 days later

  • Soybeans have emerged
  • Waterhemp has emerged
  • No giant ragweed

Apply Flexstar® GT 3.5 + Dual Magnum followed by Sequence (Dual Magnum + glyphosate) 21 to 28 days later

  • Soybeans have emerged
  • Giant ragweed has emerged
  • Waterhemp has not emerged

Apply Sequence (Dual Magnum + glyphosate) + Pursuit® followed by Flexstar GT 3.5 + Dual Magnum 21 to 28 days later

  • Soybeans have emerged
  • Waterhemp and giant ragweed have emerged

Apply Flexstar GT 3.5 + Dual Magnum followed by Sequence + Pursuit 21 to 28 days later

ROUNDUP READY 2 XTEND® SOYBEANS

Situation

Herbicide Solution

  • Soybeans have emerged
  • Waterhemp has not emerged
  • No giant ragweed

Apply Sequence (Dual Magnum + glyphosate) followed by Prefix + glyphosate + approved dicamba tank mix partner 21 to 28 days later

  • Soybeans have emerged
  • Waterhemp and giant ragweed has emerged

Apply Sequence (Dual Magnum + glyphosate) + approved dicamba tank mix partner followed by Prefix + glyphosate + approved dicamba tank mix partner 21 to 28 days later

If you don’t want to apply a dicamba tank mix partner, Roundup Ready 2 Xtend Soybeans can be treated as Roundup Ready 2 Yield Soybeans.

Visit the appropriate herbicide website before spraying for more application requirements, including tank mix options. Consider weed resistance on a field-by-field basis before proceeding with the programs outlined above.
