Established St. Augustinegrass and Centipedegrass: This product may be applied during both dormant and growing seasons. Best results are usually obtained when applied in early Spring or dormant periods when weeds are small or have not emerged. Do not apply more than two treatments per year. This product controls Spurweed, Florida Betony, Annual Bluegrass and many other problem weeds in St. Augustinegrass and Centipedegrass turfs. This product will control both emerged weeds and weeds from seeds. Rain or water within 2 or 3 days of application may decrease the effectiveness on emerged weeds.

Spurweed: Control of Spurweed can best be obtained by applying when Spurweed has newly emerged(December and January.)

Florida Betony: This weed emerges in the Fall. Apply this product in mid to late October followed by a second application in mid to late February.

Dichondra, Moneywort: Apply this product in early April followed by a second applicationin July. Note: Applications for Spurweed or Florida Betony generally will give control or suppression of the other listed weeds. However, as a general rule, this product will give best control when applied to young tender weeds or just prior to weed emergence.

    2 of 5 stars  Trying to kill Pennywort
    By Gary in Oak Ridge, TN on 05/30/2012
    Verified Purchase

    I sprayed the Atrazine as directed and it didnt kill the Pennywort. I waited a week and a half and sprayed some areas again and also some new areas. After another 2 weeks and a couple of rains I noticed some of the Pennywort was dead, but much of the grass around the sprayed areas was dead as well. In general, it killed more grass than Pennywort.

    5 of 5 stars  Really a weed killer
    By Andres in Gainesville on 02/04/2015
    Verified Purchase

    After fighting with a pest control service for months without results, and my front grass getting worse, I decide to try Atrazine which they said they wouldn't apply. It worked nicely and even in the winter months I cant see any sign of getting back in the weeds. I took my pest control in my own hands and I hope to use many more products as time goes by.

  • 4 of 5 stars  effectiveness of Atrazine
    By David in Greenville, MS on 05/17/2017

    I had misgivings about spraying anything on St Augustine grass. Others sprays, supposedly "safe" on St. Augustine grass were a disaster; killed the grass, as well as the weeds, specifically, clovers. But the alternative was to pull out the clover, including roots, was not possible so I got the Atrazine, and sprayed. At first, nothing happened. But after about a week, I noticed the clover slowly dying, and no apparent damage to the grass. It's too early to tell if the clover dies, and the grass lives. But I'm crossing my fingers, and hoping for the best. So I'm giving it 4 stars, for giving me agita, but it seems like a winner. I do like DoMyOwn, and have used them several times. They have never let me down, and shipping is free and fast! They get 5 stars.

    3 of 5 stars  Pre and Post emergent herbicide
    By Mark in louisiana on 03/27/2017

    Atrazine is both pre and post emergent, but is used to control very specific species in turf grass. IDENTIFY the pest correctly. MAKE SURE you apply correct rates. APPLY at the proper time for control. If you fail to do ANY of the above, you're wasting your time and your money!

    By Glenda in Rocky Point, NC on 02/28/2017

    Folks, I have read some of the reviews and I just want you to know that this is a PRE-EMERGE HERBICIDE. It prevents weeds from germinating. Buy something else to kill the weeds you have that are already growing!

    1 of 5 stars  Fertilizing My Weeds
    By Djs in Broxton on 04/09/2016

    I have used atrazine products previously with positive results. This product was a disappointment. I followed the instructions as written and I thought that I had purchased weed fertilizer instead of weed killer. It did not kill any type of weed! I wish that I had simply mowed the centipede grass and left the weed choking to my centipede. Expensive lesson learned!

QCan Hi-Yield Atrazine Weed Killer kill bahia grass and not harm my St. Augustine?

A

Since Hi-Yield Atrazine Weed Killer is not labeled as safe for use on bahia grass, it may suppress it. The most popular treatment for this would be to spot treat the bahia with a glyphosate product such as RoundUp QuikPro and then maintain the health of the St. Augustine so that it will fill in the bare spots.
