    Good on St. Augustine Floratram grass

    By Alan on 03/16/2018

    When I added sticker to the tank mix it killed the weeds that were up and didn't damage the grass like the Dismiss does. I'm going to keep using it.

    Finally a solution for St. Augustine weed control

    By Michael on 02/28/2021

    I live in South Florida with a St. Augustine lawn. My weed nemesis is something called Florida Pusley. Atrazine was not locally stocked on the shelves, so I spent several frustrating years trying out all the other available chemicals...which, even with careful spot application, burned the surrounding St. Augustine, despite labeling to the contrary, like Round Up's product for St. Augustine. Finally, after online research, I read about Atrazine and thanks to DMO, was able to obtain by mail order. After one spot application, and one week's time, the Pusley is yellowing/whitening...and the St. Augustine surrounding it is still it's pre-application green. Yahoo!

    Be patient

    By Mike on 04/26/2022

    Left a negative review after seeing the burgrass getting greener after a week. Two weeks later its all dying which is a glorious sight to behold. I guess I wanted it dead the minute I shot it, nice to know it suffered for a while.

    Good Value Atrizine

    By Jim on 11/12/2021

    Bought totally on price. Works fine and seeing results 1 week after application. If you don't use it all at once know that atrizine reacts with oxygen and clumps up over time. You cannot spray that through normal homeowner sprayers. To prevent this buy some canned "air" for dusting off electronics and photos. Blow into the the container holding the cap close to displace the air inside with the canned "air" gases. Pull the nozzle out after a bit and close down the cap. Works with paints too.

    By Keith on 06/12/2020

    I applied as directed to dichondra growing in my St. Augustine. It took about 2 weeks for the dichondra to die, but it did. The grass was not affected. I was pleased with the outcome.

    So far it appears to be doing the job.

    By Matthew on 10/02/2020

    So far so good. Only applied one trying to kill some bad Bahia grass in my St. Augustin lawn. After just a few days it appears the Bahia growth rate has slowed a lot. I have hear it will take 14 to 21 days to show some real effects on the Bahia. I had also done well with many other weeds in the yard.

    Snow in Florida

    By Ann on 12/15/2023

    I have tried other brands but this one really kills that controversial Florida snow (pusley) in my yard. It's really rampant this year so I stocked up and am going to apply again. This brand takes care of it and a lot of other weeds and doesn't harm the good grass, DoMyOwn is a great company to deal with, always on time and they keep in touch about their deliveries.

    Dollarweed

    Bought this to control a dollarweed infestation. It’s working. It does take a few weeks so be patient. It’s been 3 weeks and the weeds are just now yellowing and shriveling.

    Right for Dollarweed

    By Brian on 03/21/2025

    SW Florida has been hit in recent years with a Dollarweed outbreak, which overran many yards including ours. Atrazine STOPPED and killed the outbreak. In total two full applications did it. Our untreated neighbors yard continues to fight the weed. Great Product that WORKS!

    Grass seems happy

    By Troy on 12/13/2024

    I am vision impaired but still want the best lawn on the block. Getting the ratio right on this was hard with my vision, but with latex gloves I was able to get it right. I have applied twice and I think it is killing some of the weeds. Based on feel I can tell that the few blades of st. augustine grass are still quite healthy. I think once growing season starts again it will be even better. My neighbor who can fix anything likes this do your own site too.

    Less is more

    By Dennis on 08/31/2024

    Established St Augustine lawn Usually spray with less (half) than prescribed with very good results. This past time I used the quoted amount due to increased summer breakthrough weeds and ended up with a burned lawn. Hard lesson to learn, less is more…

    Southern AG Atrazine weed killer for St. Augustine grass

    By Bud on 06/10/2023

    My St. Augustine grass had accumulated various types of clover and weeds over the fall and winter. I used the Atrazine weed killer with very good success in killing all the weeds. I plan to reuse it on a yearly basis as needed to keep the grass weed free.
