What's eating my zebrinus zebra grass?

Miscanthus sinensis 'Zebrinus' is a robust, low-maintenance grass with few serious pests. Miscanthus mealybug is the primary concern, causing stunting and distortion inside the sheaths. Aphids are occasional visitors, and rust can develop in damp, poorly ventilated spots.

Dwarfed shoots, red-stained sheaths, distorted plumes; the pest hides deep inside the leaf sheaths making it very hard to detect early Remove and destroy infested stems; apply systemic insecticide in early spring; divide and replace severely affected clumps

Small sap-sucking insects on tender new growth; honeydew can coat lower leaves and invite sooty mold Spray with insecticidal soap or neem oil; blast off colonies with water; beneficial insect populations usually suppress outbreaks

Rust-orange to brown pustules on foliage, weakening leaves and reducing ornamental value Improve air circulation; remove infected leaves promptly; use a labeled fungicide in persistent cases; avoid overhead watering
