Curly dock (Rumex crispus ) is a nitrate-accumulating, perennial broadleaf weed. It has narrow, dark green, hairless leaves with curly or wavy margins or wider leaves with smooth to finely ruffled margins. Small, greenish flowers in whorled clusters at the end of the upright stems. Curly dock contains toxic anthraquinones, oxalates and tannins.
MECHANICAL CONTROL: mowing, digging, goat grazing
CHEMICAL CONTROL: Broadleaf herbicides such as 2,4-D or dicamba. Apply before flower elongation. Use glyphosate at early heading.
