Normally it is fine to mix two herbicides like this together. It is always recommended to do a small jar test first just to make sure they combine well and there is no clumping or separating. You will want to follow the label instructions for both products on tank mixing or how to do a compatibility test.
Per the manufacturer, you will need to wait 18 months after the last application of Tenacity Herbicide to plant anything other than turfgrass. They also advise that you do not use the grass clippings from treated turf as mulch. Please be sure to review the product label for more information and complete application instructions.
If not applied around the same time you should wait 1 week to apply another herbicide. Tenacity Herbicide when mixed with a non ionic surfactant will control crabgrass up to the 4 tiller leaf state only and is best applied when it just emerges. Drive XLR8 is actually the top product for crabgrass and can kill it best when it just emerges or after it has fully matured just not as good during the 2-4 tiller (middle) state. A methylated seed oil surfactant is also recommended for best results with Drive XLR8. Which you use can depend on the tiller stage of the crabgrass but Drive is usually the go to for post emergent control of crabgrass.
Tenacity Herbicide does not have a strong odor when it is mixed with water or during the applicaiton. There should be no odor after the product is dry.
Tenacity Herbicide can be tank mixed with other herbicides, fungicides and insecticides when following the tank mixing instructions listed on the product label. We suggest doing a compatibility test in a small mason jar first to ensure the products mix thoroughly without clumping or separation.
According to the product label of Tenacity, "Wait until the newly germinated turf has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application." Please be sure to review the product label for more information and complete application instructions.
Yes, you will apply 5-8 oz of Tenacity Herbicide per acre. With a minimum spray of 30 gallons per acre or 0.75 gallons per 1,000 sq ft. We always recommend to read the product label for complete application instructions.
There should be no issues applying Tenacity around the same time as a fertilizer with micronutrients as long the label on the fertilizer does not state that it cannot be used with herbicides.
Tenacity Herbicide is not labeled to control or kill ajuga. We currently do not have any products that are labeled to eradicate Ajuga/Bugleweed, you may have to spot treat with something like Roundup QuikPro in the areas that have the weed and then reseed the areas in 2 weeks
Tenacity Herbicide should be appllied after you have leveled your yard so the barrier is not disturbed or covered with other soil where seeds would not be effected by it.
Tenacity is safe for use on Bermudagrass only if the Bermuda is completely dormant. It cannot be applied to grass that is already growing.
We are not aware of a selective herbicide labeled to treat blue star creeper. You could potentially use a non selective product such as RoundUP Quikpro and reseed/resod in those areas.
No, Tenacity Herbicide is not labeled for application to carpetgrass. It is only labeled for use in Kentucky Bluegrass, Centipedegrass, Buffalograss, Tall Fescue, Perennial Ryegrass, Fine Fescue, St. Augustine Grass (grown for sod only)
Tenacity is not labeled to treat corn speedwell. We would recommend Speedzone EW. Please refer to the label for tolerant turf types and complete application instructions.
Tenacity Herbicide can be used as a spot treatment for existing broadleaf weeds once the new lawn is established and has been mowed at least 2-3 times.
Tenacity Herbicide is not labeled for trees so spraying around the trees could possibly harm them. It states on the product label: Avoid applications over the top of exposed roots of trees and ornamentals. Just about all herbicides are going to have the restriction that applications should be kept out of the dripline of desirable trees. The best you could do is carefully spot treat the weeds themselves and not broadcast in these areas.
Tenacity Herbicide should be applied at least 15 ft away from any edible vegetation.
Tenacity Herbicide is not specifically labeled for Epipactis or Helleborine. There is an article here helps explains how to eliminate it.
Tenacity Herbicide can be applied 30 days apart. Three are the most applications that are recommended depending on the weed you are treating for.
Tenacity Herbicide does not list creeping beliflower on the label as tolerant or a weed controlled. We would suggest contacting the manufacturer Syngenta at 336-632-6000 for more information.
