Nipplewort is an annual weed that is usually most common in grain fields. The seeds of this species germinate early in the spring. Early growth has a rosette form from which a flowering stem will bolt. The flower is yellow and is somewhat similar to a dandelion. Herbicides such as 2,4-D readily control nipplewort when applied at the seedling to rosette stage. Control with herbicides after the plants have bolted and flowered is difficult. In pastures, consideration should be given to the effects of herbicides on legumes or other desirable broadleaf plants. Mowing or clipping to remove the flowering stems will provide some control by limiting seed production of this annual weed.
