Since the Trimec Southern has a retreatment application of 30 days, we generally recommend waiting that long to apply another post-emergent herbicide. Centipede is a pretty sensitive turfgrass, so you do not want to put too much stress on it at once by applying multiple post-emergent herbicides at the same time. You may be ok waiting 1-2 weeks between these applications, but we suggest testing a small area for tolerance before treating the entire lawn.
Trimec Southern Broadleaf Herbicide is not labeled for ryegrass, but Negate 37WG can be used to control annual and perennial ryegrass in bermudagrass.

Trimec Southern Broadleaf Herbicide is applied at 0.37 - 0.75 oz per 1,000 sq. ft. The amount of water is not as important as making sure to apply the solution uniformily over the 1,000 square foot section. Most herbicide labels will list how much active ingredient should be used per 1,000 square feet. To calibrate your equipment, for example, mark off an area of 1,000 square feet, and cover that area at your normal pace as evenly as possible. If you used an entire gallon, you would use the recommended amount in 1 gallon of water. If you only use ½ gallon to cover the 1000 square feet then you mix the recommended amount on the product label in a 1/2 gallon of water.
Do not apply Trimec Southern Broadleaf Herbicide to newly seeded turf until after the second or third mowing.
