You can mow your lawn 2 days before application of Tenacity Herbicide and 2-3 days after application.
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 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.
When the label states that no applications should be made when temperatures are above 80 degrees, this means that the product should not applied when it is 80 degrees and above. Tenacity Herbicide can be sprayed in the evening time and/or early morning hours.
Tenacity that has been mixed with water and a surfactant should be used within 24 hours of mixing and then discarded. If it is in its original container and stored away from extreme temperatures, it will have a three year shelf life unmixed.
When mentioning Tenacity Herbicide and temperature, we are referring to the temperature at time of application. If it gets above 70 degrees after your application has dried, that is okay.
The foliage of weeds treated with Tenacity cease growth after the application, then turn white (loss of chlorophyll), so death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.
Tenacity should not be applied with a hose end applicator. Tenacity if not applied evenly across the yard can temporarily whiten your lawn and cause you to not see full control of the weeds you want to eliminate. Also most hose end sprayers will not dial down to the small amounts needed per 1000 sq/ft that the Tenacity requires. Tenacity is best applied with some form of a pump/tank sprayer in even strokes without excess overlapping.
According to the Tenacity product label you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallon of water for spot treatments, using 1 gallon per 1000 sqft.
