Dodder is parasitic and damaging to leguminous crops, especially alfalfa and clover. It also impacts vegetable and forage crops, ornamentals, native plants, and weeds. Dodder can suppress or kill the host plants.
Mechanical Control It is easier to prevent dodder establishment, than to eradicate it. When dodder is confined to small areas, it is recommended to cut it, let it dry, and burn it.
Cultural Control Rotate dodder infested fields with grasses, which are immune to dodder and will not be a host crop. Prevent new infestations by cleaning combines and farm equipment. Hay with dodder seed should only be used in feed lots.
