The Trimec Southern product label does not indicate nor give directions for tank mix combinations. Therefore, we would recommend that you contact the manufacturer, PBI Gordon at 800-821-7925 for further assistance regarding tank mixtures.
For broadleaf control, you would mx 0.75 oz Trimec Southern per 1,000 sq. ft. or approx. 1 gallon of water. You would want to mix approx. 1.5 oz with 2 gallons of water to cover a 2,000 sq ft lawn. You should not apply to newly seeded turf until after the second or third mowing.
Most EPA-registered herbicides like Trimec Southern Broadleaf Herbicide and fertilizers can safely be mixed together so long as the labeled rates are followed. We recommend that you read and follow the label instructions to prepare a tank mix test to make sure the products are compatible
Trimec Southern Broadleaf Herbicide should not be applied to Centipede during spring green up per the product label instructions. Please provide the targeted weeds for an alternate recommendation. Thank you!
