Control
Prevention Learn to
identify plants; choose alternate plants for landscaping; do not allow
ornamentals to escape
Biological No known biological control
Cultural Keeping desirable vegetation healthy and thick will
help keep invaders out; dont let plants go to seed
Mechanical Pulling/digging small patches can work; important
to get the root; wear protective clothing
Chemical Due
to the waxy cuticle, must use an appropriate surfactant with the chosen
herbicide; 2.4-D, dicamba and glyphosate should be effective.
