    Q
    Can you spray the soil with atrazine before installing new St. Augustine sod?
    A

    We wouldn’t recommend using Hi-Yield Atrazine prior to laying St Augustine sod.  The label states that it should only be applied to turf that isn’t under stress, and mentions that it could stunt the growth of or yellow sprigged turf

    Q
    Is it okay to spray Hi-Yield Atrazine Weed Killer if the temperature gets above 90 after it is applied?
    A

    Hi-Yield Atrazine Weed Killer can be applied early in the morning before temperatures reach 90 degrees if it's expected to get this hot on the day of application.  You just do not want to apply during the time of high temperature because your desirable turfgrass is under more stress in high heat.

  • Asked by Jane from Alachua, Fl
    03/31/2017
    Q
    I do not want wild bermuda grass to invade my new St. Augustine sod. Will Hi Yield Atrazine kill the bermuda?
    A

    Hi-Yield Atrazine Weed Killer is not labeled to control Bermuda grass in St. Augustine. Unfortunately, because Bermuda and St. Augustine grasses are so closely related, there is nothing that will kill the Bermuda without harming the St. Augustine as well.  It is typically recommended to spot treat the Bermuda with a non-selective glyhposate product and kill it directly, and then replant St. Augustine in those areas if necessary.

  • Asked by David from Wynnewood
    04/09/2019
    Q
    What would the ratio of Hi-Yield Atrazine Weed Killer be with a sprayer hooked to a water hose?
    A

    Applications should be made only with a hand pump sprayer equipped with a flat fan spray tip. Correct calibration of the sprayer is essential. Overdosing will cause severe plant injury and or death to the desired turf. Hi-Yield Atrazine Weed Killer should not be used in a hose end sprayer. Please review the product label to be sure this product fits your needs.

  • Asked by Jack from New Tripoli, Pa
    09/12/2017
    Q
    What can remedy the effects of Hi-Yield Atrazine once it has been applied to grasses other than Centipede or St Augustine?
    Lawn appears dead in spots Want to reseed as soon as possible
    A

    Unfortunately, there is little that can be done to counteract the effects once Hi-Yield Atrazine has been applied to a grass species other than Centipede or St. Augustine grass.  You can replant, but the product label states that if you are replanting with anything other than Centipede or St. Augustine, the minimum wait time for replanting is 12 months.  You may wish to contact the manufacturer directly to see if they have any other recommendations.  You can reach VPG/Hi-Yield by calling 855-270-4776.

  • Asked by B.
    06/07/2018
    Q
    Will Hi-Yield Atrazine Weed Killer kill Chamber bitter in St. Augustine grass?
    A

    Hi-Yield Atrazine Weed Killer is not specifically labeled for chamberbitter. This is a very stubborn weed. Pre emergent applications with a product like Isoxaben 75 WG have proven to be the most effective way to control this weed. Research from several extension pages do suggest the use of Atrazine for this weed, but we are not able to guarantee its effectiveness. Also keep in mind given how persistent and pesky chamberbitter is, there is no one and done solution to take care of the weed so repeat application may have to take place in order to fully kill the invaders.
