Weeds Controlled or Suppressed:
Annual Bluegrass (Poa annua), Chickweed (Commonand Mouseear), Crabgrass (suppression only), Cransbill, Cudweed, Dichondra, Florida Betony, Henbit, Knotweed, Lespedeza, Moneywort, Mustards, Narrowleaf Vetch, Parsley-Piert, Pennywort (Dollarweed), Sandspur, Smutgrass, Spurge, Spurweed, Swinecrest, Woodsorrel and various annual clovers.
Established St. Augustinegrass and Centipedegrass:
This 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 controls Spurweed, Florida Betony, Annual Bluegrass and many other problem weeds in St. Augustinegrass and Centipedegrass turfs. This 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. However, for the control of weeds from seeds, rainfallor watering is necessary within 7 to 10 days after treatment.
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.
WARNING: This product can expose you to chemicals including Atrazine, which is known to the State of California to cause birth defects or other reproductive harm. For more information go to https://www.P65Warnings.ca.gov
Trying to kill Pennywort
By Gary on 05/30/2012

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.

Really a weed killer
By Andres on 02/04/2015

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.

I want to kill Poa Annua and thought KBG would not be harmed if Hi-Yield Atrazine Weed Killer is safe on St. Augustine lawns.

My once-beautiful yard has been taken over by florida betany. It's the plague! Atrazine is the best herbicide I've found to kill it, but I've had to use it more often than twice a year, more like four times, twice in the Fall and twice early Spring.

I used it last year and it worked fine. Unfortunately, it rained 36 hours after applying this year. Can i reapply another spraying now?

Hi-Yield Atrazine Weed Killer is not labeled to be used around corn. We are not as familiar with products that are safe to be used in agricultural areas as we are new to that side of products. We recommend contacting your local department of agriculture to get recommendations that local farmers use for weed and grass control in crops. Once they give you a product name or ingredient, give us a call and we would be more than happy to see if we carry it or can get it for you.
