Verticillium wilt is a soil‑borne disease that can cause significant cotton yield losses, particularly under cool, wet conditions and in later‑maturing crops. It is widespread across NSW and parts of Queensland, can be difficult to diagnose in the field, and is impossible to eradicate once established.
Management focuses on prevention and reducing disease pressure through hygiene, accurate diagnosis, variety choice, crop rotation, careful irrigation and nutrition, and timely crop residue management.
