Disease pressure varies dramatically across regions, but increased humidity, cloud cover, and overnight moisture have created ideal conditions for fungal outbreaks in many parts of Australia. Turf managers, growers, and agronomists are again seeing spikes in dollar spot, brown patch and leaf spot diseases — particularly across irrigated turf, golf greens, ovals, and warm-season grasses.
Seasonal Disease Trends
Warm, humid conditions trigger rapid fungal growth, especially on high-traffic or regularly irrigated surfaces. Dollar spot and brown patch remain the most common diseases in:
- Couch and kikuyu turf
- Sports turf and fairways
- High-maintenance irrigated lawns
- In broadacre systems, foliar diseases such as septoria, rust and blotches continue to reduce yield potential where fungicide programs are delayed or under-strength.
