K-State Turfgrass

Little Barley Control Options (or Option)

(By Jared Hoyle, KSU Turfgrass Research and Extension)

I was walking through some of our research plots (with waders on due to all the rain) and I came to a nice patch of little barley.  It was lush!  I thought to myself, “How did this get so bad?” but, then I noticed there wasn’t any turf in the area at all.  Little barley (Hordeum pusillum) is a winter annual that is many times confused with foxtails because the seedbed look similar.

But the problem is I have lots of little barley and what do I do;

1.Promote healthy dense stand of turfgrass. Maybe overseed this spring/early summer if you have to depending on your situation and turfgrass species. Definitely overseed in the fall if you have cool-season turfgrass.

2. Use a preemergence in the fall.

3. Can use Certainty (sulfosulfuron) in warm season turfgrass but typically don’t.

4. Do nothing….  Seems like a trick question but this species will thin and die as temperature increase in the summer.

So there are a couple of options but if you do have little barley it is probably because the turfgrass isn’t doing well.
