    Q
    When can I use Hi-Yield Atrazine Weed Killer to control chamberbitter in St. Augustine and Centipede lawn in GA?
    A

    Hi-Yield Atrazine Weed Killer is safe for St. Augustine and Centipede lawns in GA if applied as directed on the product label for listed weeds.  It 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. Please contact your local cooperative extension office for additional products and recommendations for this application.

    Will Hi-Yield Atrazine Weed Killer kill spear grass in St. Augustine?
    A

    Q
    After the Hi-Yield Atrazine Weed Killer is applied, what action is required after that?
    Little knowledge of lawn care here! Do I just wait for the weeds to die? When can I apply an ez seed? Trying to get my centipede grass free of crabgrass (there's lots of it!) and want to make sure I'm doing the right thing!

    There is no action required after an application of Hi-Yield Atrazine Weed Killer. You should allow 10-14 days for plants to show signs of dying. According to the product label: Rain or water within 2 or 3 days of application may decrease the effectiveness on emerged weeds. However, for the control of weeds from seeds, rainfall or watering is necessary within 7 to 10 days after treatme

    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.

    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.
