RUSH SKELETONWEED Chondrilla juncea Life Cycle: Perennial Plant Description:

Perennial that grows close to the ground before bolting, similar to the common dandelion. Stems of the mature plant are sparsely leafed and appear wiry, 1 to 4 feet in height. Downward-bent, coarse, brown hairs can be found on the lower 4 to 6 inches of the stem after the plant has bolted. Leaves are small and lance- shaped. Flowers are bright yellow and ¾ inch in diameter.

Treatment: Apply 16 to 20 fluid ounces of HighNoon ® herbicide per acre.

The best time for spring treatments is at the rosette to early bolt stage (1 to 4 inch flower stalks). Fall applications are also very effective when there is adequate moisture.
