Another fungal disease that can affect this plant is rust. Rust manifests as orange or brown spots on the leaves and can also lead to defoliation. To manage rust, remove infected leaves and again, avoid overhead watering.
Pests
Several types of pests can affect Carex pachystachya Cham. ex Steud. var. monds-coulteri L. Kelso, including aphids, spider mites, and scale insects. These pests can cause stunted growth, discoloration, and deformation of the plant.
To manage pest infestations on this plant, you can use insecticidal soaps or oils.
