Do not apply dicamba products when inversion conditions exist. There is more than one method such as smoke test and weather apps which can help to determine temperature inversion conditions in a field. The following are the indicators of presence of temperature inversion conditions:
- Calm day with wind speed less than 3 mph;
- Clear night;
- Dust cloud hanging on the side of the road;
- Dew or frost present on the ground;
- Horizontal smoke pattern; and
- Ground fog in low-lying area.
- If you farm in the central sands or NW Minnesota, MDA has collaborated with NDAWN to offer NDAWN Inversion Smart phone application the provides temperature inversion alerts based off of local ag weather stations. Inversion apps are merely a tool to identify temperature inversions. It is applicator’s responsibility to protect sensitive crops and areas from pesticide damage.

Applicators must document a sensitive crop registry was consulted prior to the application. Documentation must include the name of the sensitive crop registry and the date it was consulted. The Minnesota Department of Agriculture administers Fieldcheck for registering sensitive crops. For more information visit Fieldcheck.

Yes, dicamba products such as Clarity can be applied before planting DT soybeans. The product label for old dicamba products such as Clarity require at least 28 days rotational crop interval (days after application); and a minimum accumulation of 1 inch of rainfall or overhead irrigation must be observed following application. These requirements may vary from product to product or there may be additional label requirements. For example, planting interval for Banvel is 60 days. Therefore, carefully read and follow all label requirements. This longer planting interval must be applied because DT soybean is not listed on Banvel, Clarity, DiFlexx, or other dicamba products.

For best control, post emergence dicamba applications should be made when broadleaf weeds are less than 4 inches in height. To manage broadleaf weeds, especially herbicide-resistant waterhemp (emerges throughout the growing season) after June 12th, the MDA recommends growers follow the University of Minnesota Extension recommendations on layering of residual herbicides such as Dual, Outlook, Warrant, and Valor. Incorporation of layering of residual herbicides in herbicide programs provide residual control of late emerging weeds.
If you do not have herbicide-resistant waterhemp in a field, herbicides from these three sites-of action can be applied:
- Glyphosate (Group 9)
- ALS inhibitors such as Pursuit, Classic, FirstRate (Group 2)
- PPO inhibitors such as Flexstar, Cobra, Cadet, Ultra Blazer (Group 14)
Growers that have glyphosate-resistant waterhemp may consider using tank-mix of glyphosate with an herbicide from Group 2 or Group 14.
In other genetically engineered soybeans, for instance LibertyLink soybeans, applicators can use Liberty (Group 10) herbicide in addition to other labeled herbicides for weed management.
The MDA also highly encourages growers to use preemergence herbicides with residual control and to follow resistance management strategies, such as:
- Do not rely on a single herbicide site-of-action
- Apply full labeled rates
- Use preemergence herbicides with residual control
- Zero threshold for herbicide resistant weeds (for example: waterhemp) avoid application of herbicides with the same site-of-action more than twice in the season, incorporate non-chemical tactics (such as crop rotation, cover crops, weed free seeds) that are mentioned on the label as part of integrated weed management.
