glyphosate
Rate Full strength for cut stem treatments.
Time Apply any time of year, including when plants are dormant or actively growing.
Remarks Cut plants at 3 to 4 inches below the crown and apply adequate product to wet the freshly-cut surface of the root. Foliar treatment of white bryony is difficult because it twines over desirable vegetation. If white bryony vines are separated from supporting vegetation, it may allow for selective foliar treatment with glyphosate.
Caution Glyphosate is nonselective, so other vegetation coming into contact with the herbicide may be injured or killed.
