   I have read the article that University of Wisconsin came out with about the Primo Calculator, I have been using on my bentgrass greens for almost 3 months and Im very impressed! I was wondering if anyone has seen one for Bermuda grass? I have one chipping green that is Bermuda and Id love to use something similar on that green and my fwy's.
   
   Thanks,

   We have been using the weather channel also using the 0 degree Celsius model. Spraying between 100-200 gdd. Having great results on the program.

   For those of you using the Weather Channel Calculator how do you determine the base temp?

   Sean,
   
   Based on the webcast I watched here on GCSAA, "GDDs for Timing PGR Applications", it was said that the 0 degree Celsius model was the best to use for tracking GDD for PGR's. I keeping a running log from Jan 1 till now tracking the GDD. Right now with the heat wave I am making a Legacy app @ 10oz/A every week to fall into the 100-200 GDD schedule. Before that it was about every two weeks. Its a little pricey with the Legacy but the results are wonderful.
