Trimec Southern is a concentrated product that must be diluted with water prior to use. We have linked the product label below so you can review the application instructions:

Trimec Southern Broadleaf Herbicide is not labeled to harm or not bahia grass. We recommend using a product that specifically states bahia grass will tolerate it. Please look in to Fertilome Weed Free Zone. This product will treat many different types of broadleaf weeds and bahia grass will tolerate it.
One of our most popular general weed control product that is post emergent is the Trimec Southern Broadleaf Herbicide. Trimec Southern is labeled for just about any weed you could have and will not harm your grass. Best of all, it comes with a surfactant already mixed in the product so you do not have to purchase and mix a surfactant separately like you do with most of the other herbicides that we sell.
How much of the Trimec Southern you use is dependent on your grass type and is found on the product label as amounts per 1000 sqft not not per gallon.
For Bermudagrass and Bentgrass: 0.75 fl oz per 1000 sqft.
For Bluegrass, Fescues and Zoysiagrass: 0.75 to 1.1 fl oz per 1000 sqft
For St. Augustinegrass and Centipedegrass: 0.37 to 0.55 per 1000 sqft
We would not recommend using Trimec Southern Broadleaf Herbicide in an area where animals will be grazing. If it has already been used, the animals should not be placed in the area for an entire grazing season.
We would recommend using Martins Clear Pasture. There are no grazing restrictions except in lactating dairy animals.
