Will Hi-Yield 2,4-D work to kill weeds in centipede, zoysia, and St. Augustine warm season grass lawns?

weeds ae actively growing and grasses are just beginning to green up. Average temperatures now 70-80 degrees during daylight hours


The Hi Yield 2, 4-D is not safe to be used on sensitive grasses such as Zoysia, Centipede and St. Augustine. An alternative that would work as a selective post emergent product for broadleaf weeds in your lawn would be our Trimec Southern Broadleaf Herbicide. As long as you do not have Floratam St Augustine grass, you can apply it to all of the grasses you mentioned. You can go over the product label for specific target weeds and see our price on our website here:
