Anuew™ PGR and Growing Degree Days

[@frankarce5242]

Interesting topic, my ? As a homeowner of cool season KBG maintained at 2.5 inches what would my target GDD be before reapplication. I understand that it will be different that putting green bent grass.

[@aaronhath]

For KBG sports fields (1 -2 inch height) the reapplication interval is around 375 GDDs (base 0 Celsius). Since lawns are taller yet and have a lesser growth potential, the window could be even wider - perhaps 450 to 500 GDD (base 0 Celsius).

Great video! It’s been hard to find a detailed explanation of GGD and PGR application. Good stuff!

Bro... I'm trying to figure this out. I'm all lost they need a growing days for dummies video lol. I watched ur tnex video 👍🏾👍🏾

So valuable. Thank U

How do you combine applying PGR's and scarifying/grooming golf greens? Is it done whilst the grass is still under regulation?

What rates are these GDD models based on?

[@aaronhath]

For GDDs on a creeping bentgrass putting green, I believe Primo rates were typically 6 fl oz/A and Anuew was typically at 8 oz/A. However, this research, by Kreuser at Nebraska, has been done on multiple species and with multiple rates. Interestingly, he finds that reapplication interval is only minutely affected by the rates of these PGRs. Increasing rates increases the percent of growth suppression vs. the untreated, but the reapplication window doesn't change much.

@@aaronhath he has said the same thing to me, but we spoke on primo and not anuew.
