Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications. Late summer/fall applications will be more effective than spring applications. If you are able to spot treat with RoundUp QuikPro, that is another option. It would still be ideal to wait at least 10-14 days after applying the Roundup QuikPro before raking out the dead plants and re-seeding those areas.
No, Tenacity Herbicide should only be applied to the turf grasses listed on the product label.
Tenacity Herbicide should not be applied in a mist blower/fogger. It can be applied with a hand pump sprayer or backpack sprayer for more accurate applications to the listed turf.
Yes, Tenacity Herbicide would be safe to apply now.
Roundup products contain glyphosate which is non selective so kills pretty much anything that it is applied to. Selective herbicides like Tenacity Herbicide only kills those weeds that are listed on the product label and are generally safe for use on turfgrass.
After using Tenacity Herbicide you can triple rinse the sprayer or use a spray tank cleaner to ensure no residual is left.
Mowing before applying Tenacity Herbicide is not required but if you are going to do so be sure to mow 2 days before applying or wait 2 days after.
Tenacity Herbicide is only labeled to be used on bermuda when it is dormant, otherwise it can be sensitive to applications and could harm it.
Tenacity is not labeled for Johnson Grass but it is labeled for yellow nutsedge. Acclaim Extra Selective Herbicide will control seedling Johnsongrass, and it will suppress rhizome Johnsongrass and is safe for use on cool season turf.
Tenacity Herbicide can be tank mixed with Atrizine. However, when it is, you will need to use Tenacity at the reduced rate of 4 ounces per acre or less.
Yes, Tenacity Herbicide can be applied prior to, at, or just after seeding as directed on the product label.
Tenacity is labeled for control of yellow nutsedge only. Tenacity does not cover other species of nutsedge. We do carry Sedgehammer which is labeled for all species of nutsedge.
Unfortunately there are no products available (that we carry or others carry) that will kill the Dallisgrass without killing the surrounding St. Augustine grass. The best option once it has emerged is to either spot spray or wipe on something like Round Up Quick Pro, or hand dig up the clumps of dallisgrass down to the root system and re-seed.
Tenacity Herbicide is safe to be used only on dormant Bermuda lawns. Please refer to the product label for application instructions and mix rates.
When spot treating with Tenacity Herbicide, you can aerate any time after that without any issues. If the plan is to make a broadcast application, we recommend to aerate before the treatment is applied.
Post-emergent herbicides like Tenacity Herbicide work best when the target weeds is young and actively growing and temperatures are between 65-85 degrees..
No, We would not recommend pulling up any weeds because the product will not get into the root system, and the weeds may come back at that point. After spraying with Tenacity Herbicide, the foliage of treated weeds cease growth after application, then turn white(loss of chlorophyll), and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.
We would recommend contacting the airline directly for restrictions on transporting Tenacity Herbicide in the air.
