    01/05/2021
    Q
    Can Hi-Yield Atrazine Weed Killer be used by itself or in combination with prodiamine in Miami FL this time of year (January)?
    Already applied my first round of pre emergent of dithiopyr (Hi yield turf & ornamental weed & grass stopper with dimension) in November. Was planning on throwing down some prodiamine next this month (January). Is it recommended to also throw down a pre emergent with atrazine at the same time or wait some time and if wait, when is optimal time to throw down atrazine as pre emegerent in south Florida? Thanks
    A

    Hi-Yield Atrazine Weed Killer should be used as instructed on the product label. Hi-Yield Atrazine Weed Killer is to be mixed with water only. Combinations with other chemicals in the application mixture are not recommended. For the best time to apply these products, we would recommend contacting your local cooperative extension office as they will have information for your specific region. There is no wait time between applying this product and a pre emergent such as Prodiamine.

    Q
    When to apply Hi-Yield Atrazine Weed Killer on Mississippi GulfCoast.
    A

    The best time to treat with Hi-Yield Atrazine Weed Killer depends on if you are using a pre-emergent or post emergent application. For post emergent control it is best applied when weeds first start to emerge and are young.  For pre-emergent it needs to be applied before target weeds geminate..  You may contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.

  • Asked by Clara from Metairie La

    Q
    When to fertilize after Atrazine sprayed early March?
    St Augustine yard got sprayed with Atrazine early March. Location is New Orleans. When do I fertilize my yard and is a typical
    A
    Fertilization helps to keep your lawn healthy and maintain that desired green color. It's important to apply fertilizer at the right time of year and at the right amount, otherwise you will end up with a mediocre lawn. Over-fertilization can cause random patches of long grass, giving your lawn an uneven look. Under-fertilization can cause sparser, less full looking lawns, and makes it easier for weeds and disease to take hold.
    We recommend using a soil analysis test kit or taking a sample of your soil to your local cooperative extension so your soil can be analyzed to determine what nutrients your soil is lacking. The healthiest, hardiest lawns are fertilized 2-4 times per year, fall, summer, early spring and late spring. When fertilizing in the spring you can choose to use a "weed and feed." These products contain both a fertilizer and a pre-emergent herbicide.

  • Asked by James from Virginia Beach, Va
    03/31/2021
    Q
    Is Atrazine harmful to Zoysia grass varieties and how long before rain can it be used?
    The instructions indicate it is OK to use on centipede and St. Augustine which are similar to Zoysia in growth and root structure. Atrizine has been indicated by some users as being safe for Zoysia. Might that be he case in some perhaps early or late season application?
    A

    Hi-Yield Atrazine Weed Killer is not labeled to be used on Zoysia grass and is only for use on St Augustine and Centipede grass types. If you choose to use this on your zoysia lawn we would suggest testing it in a small inconspicuous spot first and give 1-2 weeks for results before treating any other sections of the lawn. We have tons of other broadleaf herbicides safe and labeled for use on zoysia on our site such as Speedzone Southern.
