What Pre and Post Emergent Herbicide can I use on my lawn? I have a spreading infestation. 2, 4, D does not seem to work well. Can you name some brand name herbicides such as Barricade, Halt or Galleria. Bob Meyer N. Ogden, Utah Cell 801-920-7285

As you've discovered, Oxalis is tolerant of 2,4-D and many of the common 'Trimec' products. This page from N. Carolina gives a table with efficacy of available products. Be aware that the label includes products for warm-season species (e.g. atrazine). http://www.turffiles.ncsu.edu/PDFFiles/004375/Woodsorrel_Yellow.pdf
