Q

Can I spray Tenacity at the same rate if I already used it as a pre-emergent in August?
I plan on overseeding in September.

A

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 …

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.

Q

Weeds have kept growing and have gotten worse since Tenacity application last week, should I reapply?
I mixed 2 gallons of water, 1 teaspoon of Tenacity, 3 teaspoon of surfactant, as well as 3 teaspoons of Lazer Blue Ddye. I covered all the weeds, crabgrass, and clover thoroughly, but after a week all weeds have grown larger, more green and brighter yellow than I've ever seen them in my yard. I measured and it is 2 weeds per squarefoot. By now shouldn't the weeds be smaller or looking sickly? Can I go ahead and reapply now? Or should I switch to a different product?

A

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.

Water-in Tenacity Herbicide on dormant Bermuda?

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.

Q

Will Tenacity control Italian ryegrass?

A

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.

Q

If my chickens ate a couple weeds sprayed with Tenacity is it safe?
So my chickens ate a small amount of weeds that I sprayed with tenacity 4 hours ago....should I be worried? Should I prepare for chicken stew instead of eggs?

A

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.

Q

Tenacity with Scott's Sun & Shade
I have 40 lb bags of Scott's Sun & Shade containing 20% creeping red/bolster chewing fescue. I've read you cannot use this with “fine fescue”. Am I ok to put down tenacity at the time of seeding or should I wait or put it down before seeding? Delaware

A

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 fir…

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.

Q

I forgot to add the non ionic surfactant in the mix of Tenacity Herbicide when I applied to my lawn. I immediately came back and over sprayed with the non ionic surfactant. Will this be effective for post emergent control of listed weeds?

A

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 m…

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.

Q

Can Tenacity Herbicide be used with Battleship III?
My lawn care service uses Battleship III when applying fertilization applications. Can this be used in conjunction, because it is clearly not working for clover and crab grass in the lawn.

A

Battleship III is only for controlling broadleaf weeds and will not effect crabgrass or other grassy weeds at all. The label does not mention tank mixing with herbicides like Tenacity only fertilizers so we would not recommend doing so.
