As we start wrapping up corn planting, many people are looking toward planting some soybeans. While many other inputs are important considerations at planting, weed management decisions this time of year can be critical to maintaining clean fields throughout the season. Starting with clean fields at planting and applying a residual to keep them clean for the first part of the season will allow flexibility when making the first postemergence application, regardless of what postemergence herbicide program you have planned.

With that being said, your postemergence program should be considered when choosing your preemergence herbicides in order for them to be complementary. There are many excellent preemergence herbicides available to use in soybean, however understanding their strengths and weaknesses will allow you to choose the appropriate products for your system. Consult the the Weed Management section of the portal and the NC Ag Chem Manual for specific recommendations for rate and use considerations.
