   Wondering if anyone had success with gibberellic acid on greens to help grow out of a growth regulator (Primo). Found a product called Ascend sprayed at 4 oz/Ac. Growth has been severely stunted and look blah! Any help would be greatly appreciated. A1/A4 greens.

   I've used Pro Gibb on Bermuda. Rate I remember was 1-3oz/ac. I can tell you though, it doesn't take much! A few applications will do the trick.

   Gib products will work but you are playing with fire. Like Andy says, plant hormones are powerful things. You usually end up with wide leaf blades and puffy turf. Consider some of the biostimulants. Trying to attach an article about one we worked with at UMD. http://gsr.lib.msu.edu/2000s/2002/020316.pdf

   Hey it should grow out of the Primo pretty quickly once the 200 growing degree day hit. It wouldn't be that long would it? I didn't see where you are located but you have cool season greens.
   
   Just my guess and opinion on it.

   I'm with Mel on this one...wait it out. Gib acid too risky. Park the mowers and just roll. Beware the rebound effect. Don't hesitate to retreat to keep them from coming totally out of regulation. If appearance is the issue, spray a little iron for color.

   Try some astron it has a small amount of G A in it. Also a "tickle" of urea coupled with bit of iron every ten days. A couple of years ago my former spray tech put out primo, trimmit, banner, and some urea out a a 6X rate (he read total amount used instead of tank amount). First thing we did was mow with baskets to remove what we could. Then no water and called all the experts at the universities. They all said that they were not sure what would happen, or buy lots of seed and freshen up your resume. After talking with Keith Happ of the USGA we decided to try some G A on a small area, and wow you could almost watch the grass grow. We decided that the G A was to risky and let it play out. The affected fairways looked real bad weeks 3 and 4 and began to turn around week 5 and 6 and by week 7 and 8 they looked great. Little to no difference where the G A was used vs not, G A area did have little let root mass. Talk about some pre-stress conditioning (this all took place end of April).

   Have used on a green after 14oz rate was put on fairways and the tech did not turn off boom. It did not do miracles, but probably saved both our jobs. Also use after cold days in south Fl. love then that purplish color goes away fast.

   Had a similar problem when we went out at a high rate of Trimmit on our bluegrass fairwars and used a product called ProGibb (http://www.valent.com/agriculture/produ ... /index.cfm). We had a hard frost that browned out the turf and we sprayed the product to help bring it out of regulation. ProGibb worked great, perhaps too great, but the turf went from brown to almost lime green with a significant amount of growth albeit very thin and upright growth. Almost looked like the entire fairway had etiolated, but the product did work. Hope this helps.
