Control:
Chemical:
"Katie Cassel (Kōke‘e Museum) reported that Cherokee rose was susceptible to 20% triclopyr ester product in oil applied to cut surfaces. Drizzle applications with glyphosate, metsulfuron, or triclopyr only effective on treated parts of plants. Apparently there was not enough translocation to kill the entire plant" (Motooka
et al
., 2003).
