Trying to kill Pennywort
By Gary 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.

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.

Frustrated from Southernbellesville asked:
QWhy do the instructions on Hi-Yield Atrazine Weed Killer state to only use this twice a year?
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.
A The EPA gets to decide how often a chemical can be applied. They usually make this decision based on how long the product lasts in the environment, what kind of damage can be caused by over application and many other technical factors.
