    Q
    Can I mix Dimension 2EW with Q4 Plus Turf Herbicide and apply to Tall Fescue?
    I have a 30 gallon tank to spray for pre and post emerging weeds in May.
    A

    Q4 Plus Turf Herbicide should be fine to mix with a pre-emergent such as Dimension 2EW as long as both labeled rates are followed for application.  We would recommend doing a tank mix compatibility test first to make sure there is no clumping when mixing the two products together.

    Q
    How long after applying Q4 Plus Turf Herbicide should I wait to apply [N-Ext] Air-8 0-0-5 / D-Thatch 0-0-2 Combo? How long should I wait before spraying any other products on the lawn?
    I also want to spray my rgs on the lawn but I wasn't sure if that would affect the q4 plus
    A

    ideally, you would want to aerate and detach the lawn prior applying herbcides to avoid any distrubtion of the herbicide being absorbed into the weeds. You can view our Lawn Care Schedule Guide for more information on timing. Typically, we recommend waiting at least one week after the application of to Q4 Plus Turf Herbicide allow your turf to not become over-stressed by product application. 

    Please contact the manufacturer of [N-Ext] Air-8 0-0-5 / D-Thatch 0-0-2 Combo product for any timing restrictions.

    Q
    How long should I wait to water after applying Q4 Plus Turf Herbicide?
    A

    Q4 Plus Turf Herbicide is rainfast after 6 hours but is best applied when there is no rain expected within 24 hours after application.  It is more if there are dry conditions that you need to water 24 hours before or after application.  Per the product label if rainfall is not expected within 2 - 7 days you should water in yourself 1/2 inch as recommended.

    Q
    Is Q4 or Speed Zone best to mix with Tenacity and a surfactant as a general weed killer in late summer before
    I'm looking for a general weed killer that I can mix with Tenacity and a surfactant to spray my tall fescue lawn with in late summer 4-6 weeks before overseeing my lawn. Which is the best product for this?
    A
    Neither Q4 Plus Turf Herbicide nor Speedzone would be advised to tank mix with Tenacity.  Tenacity requires the use of a surfactant in post emergent spot treatment applications while the others do not, as Q4 already contains one and most Speedzone products list on the label to not mix as it can injure your turfgrass.  Depending on what you are treating for Q4 is the better option of the 3 for the most weeds.

    Q
    Using a 40 gallon pull-behind sprayer with Q4 Plus Turf Herbicide
    I plan to spray about one acre of Bermuda in Oklahoma. I did a test calibration with my sprayer and I used about 15-20 gallons of water for this area. I have a dense weed population. Do I need to change the nozzles on my sprayer in order to spray 50-220 gallons per acre like the instructions say?
    A

    If you have a 40 gallon sprayer, this is actually the ideal amount of water volume to use for most post emergent applications such Q4 Plus Turf Herbicide per acre. This gives you close to 1 gallon of finished solution per 1000 sq/ft of surface area which is the average most products and volumes should cover. You can either adjust the nozzles to allow for a heavier output as you pull, slow your speed so that you are not pulling as quickly and can allow a heavier water volume to be put out over a smaller area, or you can make essentially a double pass over the entire lawn until the tank is empty. We would recommend typically the first or second option, as the risk with double passes on the lawn is uneven distribution of the chemical and more chance of lawn burn if concentrations are high in certain spots.

    Q
    Used Q4 Plus for wild strawberry infestation in my lawn however it did not kill the wild strawberries? What can be used to kill these in my lawn?
    A

    Since wild strawberry weeds are more susceptible to herbicides when they are actively growing, it is better to wait until temperatures cool off—with mid-spring or early fall applications being the best time. 

    Q4 Plus Turf Herbicide is mixed at 1.8 to 2.6 fl oz per gallon of water per 1000 sq ft for wild strawberry. Be sure you are evenly and thoroughly spraying the wild strawberry foliage and using the 1 gallon mixed solution per 1000 sq ft area. Do not mow the lawn 2 days before or 2 days following the application.

    Please view the full product label  for more information.

    Q
    Can Q4 Plus Turf Herbicide be used safely on a lawn that is a blend of KBG and Fine Fescue?
    A

    Q4 Plus Turf Herbicide is safe for use on established Kentucky bluegrass and on fine fescue when it is part of a mix. If you have fine fescue that is not mixed with the bluegrass, then there may be some temporary discoloration. You should not add a surfactant to Q4 Plus Herbicide since this may cause extra sensitivity on the desirable grass. Please refer to the product label for complete application instructions.
