| | Controlling Wild Carrot |
 | | Wild carrot is usually found in undisturbed habitats such as continuous no-tillage crop production, roadsides and railways, fencerows, fallow fields, waterways, ditches, pastures, hay fields, lawns and around buildings. |
 | | Wild carrot may be controlled by herbicides at three stages of growth: overwintered plants with early preplant, preemergence or postemergence herbicide applications; established plants with fall herbicide applications; and seedlings with preemergence or postemergence herbicide applications. |
 | | Over half of wild carrot populations tested in the Midwest had at least one plant that was resistant to 2,4-D. This indicates that resistance of wild carrot to 2,4-D is widespread throughout the Midwest. |
