Management Information Physical: According to Martin (2002), current management approaches consist of mechanical and chemical methods. Mechanical methods should be used for small populations or where herbicides could damage desirable species. When cutting vines, cut close to the root collar to discontinue growth of existing vines and reduce seed production. W. floribunda will resprout, so it is recommended that the vine be cut repeatedly every two weeks from early in the growing season to autumn. Vines should be removed because they may continue to grow and girdle the host plant. Try to remove the entire plant (including roots) and dispose of all parts because any plant parts left can resprout. Chemical: Cut-stump herbicide applications should be used where there are large stands of established vines or where desirable plants occur and could be affected by foliar spray. Cut the vine close to the ground and apply glyphosate or triclopyr (25% solutions in water) to the cut area. If resprouting occurs retreatment may be necessary. This treatment is not effective if the ground is frozen. Foliar sprays should be used where mechanical controls would be disruptive and cut-stump methods are impractical, but additional precautions should be taken not to harm non-target species. Spray the foliage thoroughly, but do not apply so much that it drips off. Application may be more effective in warmer temperatures (above 15-18 C) because translocation is slower in cooler weather. Triclopyr is specific for control of broadleaved plants and may be beneficial if protection of valuable native grasses is of concern. Glyphosate is non-selective and should be used with care. Chlopyralid targets aster, buckwheat, and the pea family. However, chlopyralid can seep into groundwater in sandy and limestone soil types. Picloram may provide control in areas where desirable vegetation is not present.              Management Resources/Links 1. Martin, Tunyalee. 2002.
