Those pesky brown broomsedge stems — the things that crop up in abandoned and ill-managed pastures — can cause years of strife for any farmer. But there are many preventative measures that growers can take.
“Broomsedge is a native warm-season perennial grass that occupies the niches left by diminished forage species,” said Dirk Philipp, assistant professor of forages for the University of Arkansas System Division of Agriculture and the Dale Bumpers College of Agricultural, Food and Life Sciences.
“Most often broomsedge appears in mountainous areas and formerly forested fields, but pastures that have undergone the stress of drought or overgrazing also make for an ideal environment,” he said.
Allelopathic chemicals in broomsedge prevent other plants from germinating around them, making this an extremely competitive plant.
Because broomsedge can be difficult to control once established, prevention is key. Preventative options include:
Once broomsedge appears in pastures, it will be there for a while. Control options include:
There are no good herbicide options, other than glyphosate, which will also kill or damage the surrounding forage.
