Q

Why 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.

Q

What is the safe application temperature using Hi-Yield Atrazine Weed Killer for st Augustine?

How long after application must the temp stay below 85 after application to not damage st Augustine grass?

As you probably know, Centipedegrass is a very sensitive species of turf so many products that eliminate the crabgrass and other weeds can also cause damage to your lawn. Hi Yield Atrazine is safe to be used on Centipede and it will suppress Crabgrass but may not completely eliminate it. It will also control a large variety of other broadleaf weeds. Tenacity is a great pre- and post-emergent herbicide that will control crabgrass along with many other types of weeds without harming your centipede lawn. Make sure to read the Tenacity label very carefully and mix exactly what is recommended as this is a strong product and mis-using it can cause temporary turf injury. When applying Tenacity it is highly recommended to use a temporary turf colorant like Turf Mark Blue to allow you to see where you are spraying. Overlapping your application of Tenacity can cause temporary whitening of the lawn as well, but the color will return in 3-4 weeks at most. Please let us know if you have any other questions.
