Parsley-piert is a low-growing winter annual. The fan shaped hairy leaves alternate on the stems. The leaves contain three lobes and each lobe is subdivided again into 3 to 4 lobes. The flowers are inconspicuous in the leaf axis. Parsley-piert spreads by seed. Parsley-piert is found from Maryland through Tennessee into Georgia.
Young plants may be physically removed. Use of good turf management programs, including a sound fertilization program, to form dense stands of turf grass may assist in prevention of parsley-piert infestation.
For optimum control of parsley-piert, make your post-emergence herbicide application to plants that are actively growing and in the seedling to flower stage of growth.
