Trying to kill Pennywort
By Gary in Oak Ridge, TN on May 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.

I mix a bottle of this with Tenacity on my St. Augustine Floratam lawn. The combination works great but it may be all Tenacity. BTW, Tenacity is awesome on Floratam lwans.

Excellent product, shipping was fast and on time. Would purchase from this seller again.
By John in Florida on December 29, 2014
Doesn't seem to be working so well. Thought it worked on st. Augustine grass. weeds are still there and don't seem to be dying
It will be tough to use almost any post-emergent herbicide this time of year. Atrazine will provide the best control when weeds are young or just prior to weed emergence. If the weeds are not actively growing, then you will see limited results.
Really a weed killer
By Andres in Gainesville on February 4, 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.

Adam from Fairview, Pa asked:
QCan I use Atrazine on Kentucky Bluegrass?
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.
AAtrazine is not labeled for use on Kentucky Blue Grass so we cannot recommend you use it for this type of application. Most products that are labeled for poa annua cannot be used on KBG. We recommend that you spot treat the poa annua using a non-selective herbicide such as Killz All Grass and Weed Killer. Your best option for poa annua is to use a pre-emergent herbicide in the Fall such as Hi-Yield Turf & Ornamental Weed & Grass Stopper with Dimension. It will prevent the poa annua seed from germinating into weeds. It will not kill existing weeds and it is safe to use on KBG. Apply the granules and water in after application. Repeat treatment in Spring to prevent other grassy and broad-leaf weeds in your yard.

Al from Seven Lakes, Nc 27376 asked:
QI applied atrazine to centipede lawn three weeks ago with little affect on the weeds.
I used it last year and it worked fine. Unfortunately, it rained 36 hours after applying this year. Can i reapply another spraying now?
A Rain or water within 2 or 3 days of application may decrease the effectiveness on emerged weeds. Yes, you can reapply the Hi-Yield Atrazine Weed Killer again and perferably do a spot spraying of the areas that need attention to lessen the likelyhood of damage to your lawn.
