I know there are tons of product that are effective on cg. In the past i've used q4, quincept, sethoxydim, etc. When using q4 and quincept I occasionally get some yellowing, and probably because when the cg is here it's almost always above 90 and on the humid side. When August gets here most of our pre is wearing off and cg takes advantage. ----I'm curious what anyone has used on bermuda and centipede during hot weather. I normally use celcius for my post and it does great, but not as effective on mature cg. ----This time of year our fescue it about toast unless it has been irrigated and on a fungicide program. What are my options on cg in fescue. I've used q4 and quincept with great results but only tried them when the temps were under 90. The other problem is that when using them there is a 28-30 day wait before seeding. So any treatments would have to be before mid August.
