We would recommend contacting the airline directly for restrictions on transporting Tenacity Herbicide in the air.
Tenacity Herbicide is not labeled to prevent or eradicate lespedeza.
Tenacity Herbicide reapplication times can vary depending on the target weed and application. Please refer to the product label for complete information.
As long as you are not applying either product during the heat of the day, you can use SpeedZone the same day as Tenacity Herbicide. Just allow areas to dry between treatments
Tenacity Herbicide is not labeled to be applied in or around edible vegetation. When applying the product to your lawn, you would want to be sure to avoid over-spray or drift of spray applications onto the fruit trees, and avoid spraying within the drip line of any edible trees.
While you could potentially do a split application with Tenacity for a fall pre-emergent, usually you would wait at least 6-8 weeks between applications in that case. Keep in mind that the annual maximum application rate for Tenacity is 16 oz per Acre per year (used in 12 months), so you want to be careful you are not exceeding that rate. Be sure, too, that you are not exceeding the application rates for your type of turfgrass.
Tenacity Herbicide not labeled for zoysiagrass and would not be recommended to apply to it at all.
We don't recommend using Tenacity Herbicide to get rid of weeds in ornamental plants, it's not labeled for this use. If you have broadleaf weeds, you will need to spot treat with a non-selective herbicide. If you have grassy weeds, you can use a product like the Bonide Grass Beater around listed ornamentals on the label.
Foliage of treated weeds will cease growth after Tenacity Herbicide 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.
You would only need to water in the pre-emergent application of Tenacity Herbicide on dormant bermuda if you felt you did not use a sufficient amount of water during the initial application. Typically the goal is to create an even barrier in the soil with the chemical so the weeds cannot penetrate through it. Light watering no more than a 1/2 inch of rainfall equivalent is fine.
The product label for Tenacity Herbicide only states it is safe to be used on perennial ryegrass. There is no mention of it controlling Italian ryegrass, so I would not suggest using the product to control that particular weed.
Tenacity is usually pet safe as soon as it is dry. However, chickens are different and we would recommend reaching out to your vet for more information on what to do. Or you can reach out to the manufacturer for more information as well: Syngenta 866.796.4368.
If you are applying Tenacity Herbicide for a crabgrass pre-emergent, then you would apply in late early spring before soil temperatures reach about 55 degrees. Keep in mind that if you are not overseeding in the spring, you usually want to use a different pre-emergent with longer soil residual or add another one for longer and more complete weed prevention.
We have more information in our Crabgrass Pre-Emergent Guide here.
Whenever a lawn has large amounts of fine fescue its recommended to not use Tenacity unless some damage can be tolerated. Typically applying it as a pre emergent will lead to less harm than using it as a post emergent on a sensitive blend. We'd suggest applying the Tenacity as a pre emergent first, then wait 2-3 weeks to seed. Or seed and apply Tenacity 2 weeks after seeding.
Since a surfactant is designed to reduce water tension during spraying, applying it separately is unlikely to improve results. If you were applying the Tenacity as a pre-emergent herbicide, then there should not be any detriment to the application. If you were applying as a post-emergent, then you may need to reapply the product in 2-3 weeks as a spot treatment for the target weeds.
We would not recommend Tenacity Herbicide be applied to flower beds and ornamental plants. According to the product label: “Avoid over-spray or drift of spray applications onto ornamentals or flower beds and gardens. Roses and daylilies are sensitive plant species. Avoid applications over the top of exposed roots of trees and ornamentals."
Tenacity Herbicide is one of the few products that can be applied at seeding, prior to seeding, or just after seeding of new grasses to help prevent and control weeds at the same time. Be sure to check the label for any restrictions to certain turf types as Fine Fescue is more sensitive than other species when using Tenacity at seeding. Be sure to use a Non Ionic Surfactant with the Tenacity when applying for best results.
Tenacity Herbicide can be used on a lawn that 2,4 d or other herbicides have been applied to safely as long as you follow label instructions and apply it evenly. Tenacity will only last about 30 days as a pre emergent compared to other pre emergents on the market that will last 3-4 months. Tenacity is mostly used as a pre emergent in the spring or fall when customers are over seeding their lawns with a cool season grass to fill in bare spots, as its one of the only products that can be used at this time without harming the seed. If you are not seeding, you may want to consider a longer lasting pre emergent or one that covers a wider range of weeds than the Tenacity does, like the Dimension 2EW or Pendulum 2G for instance. If using Tenacity as a pre for crabgrass, you want to put it down at or just prior to your soil temperatures reaching 55 degrees in order to be effective. If soil temps have already progressed past 55 degrees your pre emergent will not do much to stop the weeds.
Tenacity Herbicide is not labeled safe for use on Floratam species and is only for use on St Augustine grown for sod.
Tenacity Herbicide is not labeled for use on pasture land, and a 90 day waiting period is required after an application until it is safe to allow animals to graze on treated areas.
