Early spring application with 2,4-D; picloram; 2,4-D + picloram; clopyralid; or clopyralid+dicamba, to rosettes achieve adequate control.
Biological: Biological control agents such as the gall midge (Cytiphora chmidti), a gall mite (Eriophyes chondrillae), and a rust fungus (Puccinia chondrillina) have proven effective. Another insect that may soon be available for the control of rush skeletonweed is the root moth (Bradyrrhoa gilveolella).
Because no single treatment provides long-term control of rush skeletonweed, an integrated strategy must be adopted. The first line of defense is to prevent introductions of the weed. Once the weed becomes established, integrate combinations of competitive plantings, crop-pasture rotations, sheep grazing, biological control agents, and herbicides should be used to reduce rush skeletonweed to manageable levels.
