I've never tried the MSM/Triclopyr mix in zoysia. I'll bet that'd smoke some Virginia Buttonweed too. I have used 3 way on lespedeza with only slight curling and discoloration of the target. Add a small amount of triclopyr and you lay waste to the lespedeza. A night and day difference. Unfortunately, 90% of my lawns are Bermuda and our conditions are much like yours most of the year. The Bermuda will only tolerate Triclopyr in small amounts during our coolest months here( winter/dormancy)
