    Application timing of Q4 Plus Turf Herbicide is going to vary depending on the types of weeds you are trying to control per the product label and it may take more than one application.  It would need to be applied when the weeds are growing not before as it will only kill the weeds it makes contact with that have emerged.  We do not know the exact time of year you will start applying Q4 in Ohio. Weeds grow at different times in different regions and there is no way for us to know down to the exact week.  Please refer to the product label for complete instructions based on whether you are treating for grassy weeds or broadleaf weeds.  If you are not sure when the weeds start to actively grow in your region you can contact the master gardener at your local cooperative extension office for more information.

    Can Q4 Plus Turf Herbicide be used to kill bermuda grass in a fescue lawn?

However, we would recommend Fusilade II because it can be used to remove bermuda grass from tall fescue and zoysia grass when used at reduced rates.

  • Asked by Bob from Newkirk, Oklahoma
    08/07/2018
    Q
    Will Q4 Plus Herbicide harm flower beds?
    Or how close can a person spray if wind is right?
    A

    You should not spray Q4 Plus Turf Herbicide on or near any desirable flowers, shrubs, or other ornamentals, and do not use clippings from turf treated with Q4 as mulch around these plants. The active ingredients can harm desirable ornamentals and some of them may volatilize, so you want to be sure you spray on a calm day and do not contact roots, leaves, or stems of desirable ornamentals. You can shield desirable plants using plastic sheeting if needed.
