We recommend allowing at least 7-14 days to see wilting/yellowing of target weeds when using Quali-Pro MSM Turf Herbicide or other post-emergent herbicides. Per the product label, control of Dollarweed may require an additional application after 4-6 weeks. You will see best results using post-emergent herbicides when the target weeds are young and actively growing. You may see some stunting or chlorosis of St. Augustine turfgrass after applying this product.
