Itch Grass

Published on 12 March 2026

Itch Grass, a locally declared pest in the Burdekin, continues to pose a serious threat to both residents and the region’s vital sugar cane industry if left unmanaged.

This aggressive weed can be identified by its long, cylindrical stems covered in fine hairs that can irritate the skin, along with distinctive spear‑like flower heads that break apart into individual seed sections. Under favourable conditions, the plant can grow to heights of up to four metres.

Beyond the discomfort it causes to people, Itch Grass presents a significant agricultural risk. Once established, infestations are difficult to control and can lead to severe crop losses in sugar cane. Each plant is capable of producing more than 2,000 seeds, with seeds able to survive in the soil for up to seven years, allowing infestations to persist long after initial growth.

Early identification and prompt management are critical to limiting the spread of Itch Grass across the Burdekin. Residents and landholders are encouraged to seek advice if they suspect the presence of this pest on their property.
