I have recently aquired my herbicide license and have been studying and practicing on my own lawn for over a year. I am about to start a program with my mowing customers for weed control. See what you think and suggest.
I am located in South Arkansas and am dealing with Bermuda, Zoysia, St Augustine & Centipede.

Ar,
Pick you up some Prodiamine too. It has a longer life than Pendimethalin but not as long of a label.
Buy you some products to control Nutsedge, globe sedge!
Throw in there a regimine for either sulfur or Lime. Gypsom if too salty! Check the pH and macronutrients.

Is there a pre that controls sedges? I plan on using Certainty for post sedge. When do you usually hit the sedge? I know you are about 2 weeks behind me timing wise. Do you use 1 app of Prodiamine in the spring or split it into 2 for the summer? Thanks for the response.
