Mix rate for Fertilome Weed Out with TriMec?

From the Fertilome Weed Out Label for spot spraying.

“ST. AUGUSTINEGRASS, CENTIPEDEGRASS, AND BAHIAGRASS:
Mix 2/3 fl. oz. (4 teaspoons) in 1 gallon of water and uniformly spray 330 sq. ft. Do not apply to St. Augustinegrass, centipedegrass, or bahiagrass emerging from winter dormancy; temperatures below 45oF within 72 hours of application may cause damage. Do not use on “Floratam” St. Augustinegrass in Florida.”

I’d mix that solution, add a couple teaspoons of surfactant and spot spray the weeds you are targeting. Don’t worry about spraying it uniformity over 330 sq ft if that’s the part that is confusing you.

Label directions for spot spraying Bermuda

“ BERMUDAGRASS, BUFFALOGRASS, AND BENTGRASS: Mix 1 fl. oz. ( 2 Tbs) in 1 gallon of water and uniformly spray 330 sq. ft. See Table 1 for additional spray preparations.”.

but it also states this

“ Limitations on broadcast applications to residential turfgrass:
The maximum application rate is 4 fl. oz. of product per 1,000 sq. ft. per application. The maximum number of broadcast applications is limited to 2 per year with a minimum of 30 days between applications. The maximum seasonal rate is 8 fl. oz. of product per 1,000 sq. ft.”.

1 oz per 330 sq ft is roughly equivalent to 4 oz per 1000 sq ft.

I’d suggest you try the 1 oz per gallon per gal for spot spraying, and add a couple teaspoons of surfactant.

I use 1 oz of Fertilome Weed Free Zone per gallon for spot spraying weeds in fall and spring and it does a good job of controlling most lawn weeds - it’s basically a Trimec herbicide but has Carfentrazone added.
