Someone correct me if I'm wrong, but it seems in this heat that anything that will kill these weeds will also kill your grass. Coming from Houston so may be different elsewhere
Where are you located?Mr. AGSPRT04 said:
I used liquid Atrizine in St. Augustine in the upper 90s a few weeks ago. Killed the weeds I was targeting, only a mild and short lived discoloration of the grass.

I'm spreading Nitro Phos Barricade south of Houston. St Augustine
Should I hit the flower beds or just the turf? Lots of Louisiana Iris in the beds that I don't want to damage.
NVM, I bought the product and read the label.
I've always put it in my beds as well - did it this morning in fact.WhoopRAB said:

I treated all of the beds.
The iris plants are so thick that even if I lost a portion it would be okay. They seem very hardy. With all of the ornamental shrubs listed, I decided to give it a shot. I'll report back if I see any adverse impact.

Would this be more effective than pendulum granules then watering in? Im in college station with st Augustine grass. First year in this house and never taken care of st Augustine before.

I would wait a couple weeks. What type of grass and where are you located?

StA in Houston.

I would wait until it turns dormant. With barricade already down, I can see some serious club roots if you apply the pendi now.

Ok, I was just thinking that since we had a bunch of rain relatively close to when I put the barricade down I may not get the full benefit, but that makes sense. Thanks.

I put my pre-emergent down at the start of October (StA in Houston) - I think I read somewhere that you should do a second round of pre-emergent 45-60 days later, is that true?
Also, re: spot treatment with Round Up - I held off on doing that in the spring/summer because my yard was newly sodded in March and didn't want to mess with new grass trying to take root. But it should be pretty good to go for spot treatment now, right?
