Tenacity Herbicide is not restricted in the state of New York. It can be applied when the soil temperature reaches 55 degrees Fahrenheit. This should be broadcast across the lawn in areas where you are wanting to prevent weeds. Be sure to water the product in 0.5 inches to activate it. This product can be applied right before it is going to rain. We normally recommend applying Tenacity in early to mid April in cool season areas.
Please check out our Cool Season Lawn Guide for tips on how and when to use products in your lawn.
According to the manufacturer, it is not advised to apply more than the recommended amount of the non-ionic surfactant. We advise you to use the ratio recommended on the product label.
We recommend using a Non-Ionic Surfactant with Tenacity Herbicide.
Tenacity Herbicide can be applied at the time of seeding for all grass types except fine fescue.
There should be no issues applying Tenacity around the same time as a fertilizer as long the label on the fertilizer does not state that it cannot be used with herbicides.
Tenacity Herbicide is not labeled safe for use on Floratam species and is only for use on St Augustine grown for sod. Atrazine or Blindside would be the alternative products to use.
Tenacity Herbicide is not labeled to control Poa Annua/Annual Bluegrass as a post emergent application. The label only states that it could cause injury to it if sprayed. It is only labeled to be used to suppress poa annua when used as a pre-emergent.

According to the Tenacity product label for smaller applications, you will need to mix 1 tsp of Tenacity and 3 tsp of surfactant to 2 gallon of water, using 1 gallon each to cover 1,000 sq ft.
Tenacity is labeled as a pre and post emergent for crabgrass but only as a post emergent for nimblewill. The most effective product to control nimblewill pre-emergently has been removed from the market (MSMA). We have had a lot of folks report that Dimension does a pretty good job pre-emergently but since the product is not technically labeled for nimblewill we cannot legally recommend it for this use.
Tenacity Herbicide should not be used within 3 feet of desirable trees or ornamentals.
