In this article, we will discuss the most common cordyline plant pests, how to identify them, and the treatment methods available.

Scale Insects

Scale insects are a common pest that affects cordyline plants. They are small, oval-shaped insects that attach themselves to the leaves and stems of the plant. Scale insects feed on the sap of the plant, which can weaken the plant and cause it to drop its leaves.

Identification

Scale insects can be identified by their small size and protective shell-like covering. They can be black, brown, or white in color and are often found clustered together on the leaves and stems of the plant.

Treatment

The best way to treat scale insects is to physically remove them from the plant using a cotton swab dipped in rubbing alcohol. If the infestation is severe, you may need to use an insecticide specifically designed to kill scale insects.

Spider Mites

The best way to treat spider mites is to wash the plant with a strong stream of water to remove as many mites as possible. You can also use insecticidal soap or neem oil to treat the plant.

Mealybugs
