Weeds Are Starting to Emerge: Even After a Preemergence Herbicide Application
During recent scouting, weeds were noticed in plots treated with preemergence herbicides. Learn some troubleshooting considerations to help determine why some weeds emerge following preemergence treatments.
Absinth Wormwood Control in the Spring
Absinth wormwood is a difficult-to-control, noxious weed that can produce great amounts of seed (50,000 seeds per-stem) and spreads only by seed, illustrating the importance of management prior to seed production.
Early Season Prevalence of Field Pennycress and Shepherd’s Purse
Many fields that are planted to winter wheat or have yet to be tilled may have a healthy infestation of field pennycress or shepherd’s purse. Learn some expert tips for identifying and managing these weeds before they become a problem this growing season.
Current State of Noxious Weed Management in South Dakota
Results of an online survey to determine how South Dakota stakeholders are currently managing noxious weeds.
Herbicide Group Classification
The intent of providing herbicide group numbers and mode/site-of-action information on labels is to help develop herbicide plans that reduce the selection pressure on herbicide-resistant weeds. Learn how understanding this information can help improve your plans.
Factors Influencing Spray Coverage
Learn about the different factors that influence spray coverage and how you can tailor your practices to ensure that proper coverage is achieved.
Preemergence Herbicide Application Considerations for 2024
Preemergence herbicides control germinating weeds, which minimizes early-season competition with crops to keep yield potential higher. Learn what factors influence their effectiveness and what can be done to avoid control failures and unintended crop injury.
Early Emerging Weeds and Effective Management
Managing early emerging weeds before crop planting or emergence is important to minimize early season competition, which can lower yield potential, even if the weeds are managed later in the season. Learn some tips for getting started.
Biennial Weed Species Have Started to Emerge
The warmer weather this year has caused some biennial weed species to emerge earlier than normal. Learn some management considerations for areas that have been historically infested with biennial weeds.
Over-the-Top Dicamba Ruling Explained
On February 6, 2024, the U.S. Environmental Protection Agency was ordered to vacate the registrations for dicamba products registered for over-the-top applications on dicamba-tolerant cotton and soybeans. Learn how the ruling will impact the upcoming growing season and beyond.
