However, research has indicated that an increase in yield is possible if seed is inoculated in a regular soybean rotation.

Update For Maximum Annual Use Rate Of Dicamba For Use In DT Cotton and Soybean

New dicamba labels for use in DT cotton and soybean included a reduction in the maximum annual use rate. This reduction applies to all sources of dicamba when using or intending to use Engenia, Stryax, or Tavium. Therefore, if you intend to apply Engenia, Stryax, or Tavium in DT cotton or soybean, you need to take into consideration other sources of dicamba such as burndown applications, cover crop termination, or applications in rotational crops made or intended to be made in the same year.
