Roundup Ready® 2 Xtend® Cropping System in Soybeans

by Matt Teply | May 24, 2018

It’s getting to be that time of year when there will start to be a lot of post emerge acres getting sprayed.  I thought this would be an excellent time to quickly go over some of the things that are key in safely applying herbicides in the Roundup Ready® 2 Xtend® cropping system.

Acres of Roundup Ready® 2 Xtend® soybeans will be higher this year. The demand for this soybean cropping system was even greater than expected within our own company.  With this increase in use of the system it is important to remember that there are some important things required when using the system.

  1. Mandatory applicator training will be required on an annual basis.  Trainings were held throughout the Fall, Winter, and early Spring Seasons.  Be sure you have attended a certified training prior to applicating chemistry used within the Xtend® cropping system.
  2. Record Keeping is also mandatory.  Chemistry within the Xtend® cropping system (XtendiMax® with VaporGrip® Technology and Engenia® herbicide) are Restricted Use Pesticides and require minimum record keeping.  Be sure you are following your state’s current minimum requirements.
  3. This is a big one.  READ AND FOLLOW LABEL DIRECTIONS depending on which chemistry you are using.  Each chemistry will have a different label.  Allowable adjuvants, tank mixes, boom heights, gallons of carrier per acre, and nozzle requirements are just a few of the things that will be found in the labels.  Again, the labels will vary depending on which chemistry you are using Xtendimax or Engenia.
  4. Application window time line in the label of both chemistries have changed.  Reduced application windows are in effect in 2018 to reduce the chances of temperature inversions and drift.  Be aware of the application windows required by the label and by the State you are applying in. 
  5. Be aware of sensitive areas or other crops in your area.  Be a good neighbor and be aware of your surroundings.  Make sure crops or plants that are sensitive to growth regulator chemistries are not downwind or put at risk because of off-target movement of the chemistries.  Follow the buffer zone requirements of the Xtend cropping system as well.
  6. One of my favorite things to say.  “Spray Early and Often.”  Maximum height requirements on weeds for control is 4 inches tall.  A pigweed can grow 4 inches in one day.  The days of drive by window scouting and seeing weeds above the crop canopy before trying to control them are over.  Growers need to be diligent and apply for best control when weeds are 4 inches tall and below.  This means some walking within fields might be required.
