Australian biology, identification & timing
Each photo’s Explore details view includes subject-specific biology or cause, distinguishing features and Australian seasonal monitoring guidance, reviewed 19 October 2026. Expand its references for the supporting botanical, entomological and turf research sources. Seasonal interpretations allow for regional climate, turf host and site history.

Record before deciding
Record turf species, location, affected area, onset, recent weather, irrigation, mowing and previous treatments. Photograph both the overall pattern and individual leaves, crowns and roots.
Seek diagnostic confirmation where symptoms overlap, the cause is uncertain or damage persists.
How to use this reference
Large Patch and Kikuyu Yellows use photographs and identifications supplied on 12 October 2026. Large Patch links to the nine Brown Patch fungicide entries as an Indigo technical recommendation, separate from registered label uses. Kikuyu Yellows carries Indigo’s current note that no registered fungicides are available. Visible-pattern filters and image cues describe the supplied photographs. They are navigation aids, not diagnostic rules. Scientific names retain the source wording.
Empty control results mean the supplied matrix has no marked entry for that category. They do not establish that no treatment exists.
