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

I might just as well have used water to kill the weeds. No result at all. it was a total waste of money. i ended up using round up from walmart.

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.

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 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.

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 I apply Hi-Yield Atrazine Weed Killer on dormant Bermudagrass?
The UGA extenstion states: "Atrazine is labeled for centipedegrass, zoysiagrass, St. Augustinegrass and bermudagrass. Atrazine can be applied to actively growing and dormant centipedegrass or St. Augustinegrass but bermudagrass can be injured if treated while actively growing. " So, can it be used to control actively growing annual bluegrass on a dormant Bermuda grass lawn?
A Hi-Yield Atrazine Weed Killer is not labeled to be used on bermudagrass at all so we cannot recommend it for this use. †We have to go by what is stated on the product label. †Drive XLR8 would be a good product to use for annual bluegrass in bermuda.
