What is your turf? I'm of the opinion that that much dimension or other pre could damage turf. Most pre-ems poop out after 6-12 weeks depending on amount. Enough to last that long could pack on the soil surface damage in a way that I have never seen. Just thinking. I'd rather error on doing two or more application than replacing a lawn. On warm season grasses, I use Gallery and a little dimension and get excellent results for 8-12 weeks.
Let us know your results should you do this as it would be good knowledge.
