L' arrêté n°65 CM du 23 janvier 2006 dresse une liste de 35 plantes envahissantes déclarées "espèces menaçant la biodiversité" dont Cinchona pubescens. Ces plantes font l'objet de mesures d'interdiction d'importation nouvelle, de multiplication et de plantation, de transfert d'une île à l'autre de tout plant entier, fragment de plant, bouture, fruit et graine. Leur destruction est autorisée. Galapagos Islands
Please follow this link Rentería et al 2006 to An illustrated guide providing practical information for the effective control of the worst invasive plant species in Galapagos. Designed for farmers and other land managers, it describes manual and chemical control methods. Cinchona pubescens is among 23 introduced species with descriptions and control options listed. Galápagos National Park (GNP)
Buddenhagen et al (2004) reviews control options used in the control of in the past and tests a variety of herbicides and selective application methods. The author concludes "A mixture of picloram and metsulfuron (240 and
15 g ai/L, respectively) killed 73 to 100% of trees when applied to connecting machete cuts around the circumference of tree trunks (hack and squirt HS) at concentrations of 5, 10, and 20% in water, with larger trees requiring higher concentrations for best results. Although this herbicide mixture also was effective when applied using other methods, HS was the least labor intensive and costly." For more details please see Buddenhagen et al. 2004

Starr et al. (2003) state "While eradication of C. pubescens in the Makawao Forest Reserve would be difficult, controlling small populations in pockets of rich native vegetation may help contain the infestation and slow the degradation of the remaining native forests in the area."
