(By Jared Hoyle, KSU Turfgrass Research and Extension)
Yellow woodsorrel (Oxalis stricta) is a perennial or annual broadleaf weed that has clover-like trifoliate heart shaped leaves. Yellow woodsorrel most commonly spreads by seeds that are contained in a capsule that when it explodes ejects the seeds. It can be confused with clover but has yellow flowers with five petals. You can find this weed in a wide range of soil conditions and can commonly be confused with black medic, birdsfoot trefoil and white clover. A similar species is creeping woodsorrel but it is most commonly found in landscape plantings while yellow woodsorrel is most commonly found in turf.
To control oxalis, herbicides that contain triclopyr and fluroxypyr are very effective.
Herbicides that contain fluroxypyr include;
- Battleship III
- Escalade 2
- Momentum FX2
- Tailspin
- Vista XRT
Herbicides that contain triclopyr include;
- 2-D
- 4-Speed XT
- Battleship III
- Chaser
- Chaser 2 amine
- Confront
- Cool Power

- Momentum FX2
- Tailspin
- Three-Way Ester II
- Turflon Ester Ultra
- Turflon II amine
- Triclopyr 4
