Hi-Yield Atrazine & 2-4-D

[homebase]

Hi,
I recently purchased a bottle of image from my local Ace hardware store thinking it would help with weeds in my yard (St. Augustine). Doesn't work very well.

I was back in the Ace hardware today and saw a Hi-Yield brand of Atrazine and 2-4-D. Can I mix these two together in my pump tank and spray? I ask becuase I wan't to knock these weeds dead. I have dollar weed and other weeds I don't know the name of.....

Thank you for your help.

24d is not good for st aug use atrazine it takes about 2 weeks to kill the weeds if you have a lot of dollar weed your getting to much water
