Cenchrus setaceus

What this means for control work

Fruit has been recorded Mar to Apr. Treat before it, not during.

Based on 7 Hawaiian field observations in which the observer recorded fruit, out of 13 annotated records for this species. These are people standing in front of the plant, dated and located to the metre — the densest Hawaiian evidence available. What they cannot tell you is whether the fruit was ripe.

Travels on boots, tyres, stock and gear. Cleaning protocols timed to the fruiting window are worth more than the same protocols applied year-round.

Wind-carried. Distance depends on the day rather than on an animal, and a plant left standing through its fruiting window seeds the neighbourhood.
