To manage mealybugs, you may use a cotton swab dipped in rubbing alcohol to remove them manually. Alternatively, use insecticides, and always follow the manufacturer's instructions on dosage and application method.
Spider mites are tiny pests that feed mainly on the underside of the leaves of the plant, causing yellowing and stippling of leaves. To manage spider mites, you may apply insecticides or use insecticidal soap. You may also introduce predatory insects such as ladybirds that feed on spider mites.
In summary, Cynanchum arizonicum is a hardy perennial plant that is not prone to disease or pest infestations. However, rust, mealybugs, and spider mites can still be a problem.
