Q: Can I use trifuralin as a pre-emergent weed controller on zoysia? I bought it before I realized it is intended for vegetable gardens. 

A: Congratulations for reading the label! University turf expert Clint Waltz says in the past trifluralin was labeled by itself for use on lawns. But there are two drawbacks: it can cause grass to turn slightly yellow and it evaporates quickly if not promptly incorporated into the soil with water. Companies found that other herbicides similar to trifluralin were more stable and less damaging. UGA weed expert Patrick McCullough notes that trifluralin is still available for lawns in a combination product called Team 2G.
