IN THE FIELD SIGHTING
Jeffrey Sorenson, Legend Sales Agronomist

With all the rain we have gotten in Minnesota lately, there have been some questions about how long growers will be able to apply dicamba-based herbicides to Roundup Ready 2 Xtend® soybeans.

AGRONOMIC BACKGROUND & CONSIDERATIONS

Dale Viktora, Legend Sales Agronomist

After the issues that were experienced last year in Minnesota, the Minnesota Department of Agriculture put some additional restrictions on the application of any dicamba-based herbicide to RR2 Xtend soybeans in Minnesota. The most notable change or restriction was setting the final application date to June 20th. There have been a few requests made to the MN Department of Agriculture to extend this date, however this request has been denied and the state has made it very clear that the cut of date of June 20th will stay.

ACTION PLAN FROM YOUR LEGEND SEEDS TEAM

Luckily, most fields had a pre-emergent herbicide applied and it looks like it is holding very well. Even though you might not be able to spray dicamba-based herbicides, there are other options for controlling glyphosate resistant weeds. Most of these options are PPO type chemistries. The PPO inhibitor herbicides are primarily foliar-applied and have limited soil activity. They are contact-type herbicides that primarily affect only the sprayed plant tissues. The leaves of susceptible plants will quickly become chlorotic (yellow), then desiccated and necrotic (brown) within one to three days. Most PPO herbicides do have an 8-10 month interval for planting corn the next year, so it is crucial to contact your local agronomist to ensure the best option for your operation.

When applying any herbicide, make sure to follow all recommendations and restrictions on the label. Restrictions for application could include: number of applications per year, grazing, feeding and harvest, but they can also include growth stage limitations: i.e. the herbicide shouldn’t be applied past R1. If you have any questions please contact your local chemical retailer or Legend Agronomist, and always follow the herbicide label.
