    Q
    Any application restrictions for lawns in N.Y. State with Tenacity Herbicide??
    How early in the Spring can you can you spray in this climate? How damp or wet should you spray to insure proper coverage?
    A

    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.

    Q
    Would it be helpful to apply a greater amount of non-ionic surfactant in the mix with Tenacity Herbicide ?
    The recommended mixture seems to be a ratio of 3 to 1. IS it possible or allowable to mix a greater ratio of the surfactant (say 5 to 1) in order to insure that more of the herbicide adheres to the creeping bent grass & various other weeds ?
    A

    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.

  • Asked by Rivk from Augusta County, Va
    03/12/2019
    Q
    Can I use Tenacity as a preemergent on crabgrass and nimblewill?
    A

    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.

    Q
    What is the differance between all of these herbicides like Tenacity Herbicide and Round Up?

    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.
