How many people that are treating non-irrigated warm season lawns use a pre-emerge in late summer? I was planning on using .5 AI of Barricade around Sept. 1, but it has not rained here in 6 weeks. If this dry spell continues, I think it will just be a waste. Not many of my customers are going to ensure 1/2" of water across there whole lawn to water in the herbicide. I may just save some money and just apply some potash and leave out the barricade. I am planning on using Simazine/3way in my last round in November. Does anyone care sharing their next to last warm season application.
