Great rains in the Southeast coupled with warmer days have allowed ALL grass types to officially jump. There's a lot of activity currently:

There are certainly no shortage of activities at the moment.

Having just attended the Clemson University field day in Florence, SC there was some really useful information to share regarding late season Poa Annua control on non overseeded Bermudagrass in the Southeast Transition Zone.

Below is a summary (comments were from Dr. Bert McCarty)

*Applications were made March 13th

Poa Control

  • Best control was the Clemson Combo. All rates were cut by ¾.
    • 2,4 D Amine 8 oz/A
    • Dicamba 4 oz/A
    • Metsulfuron .5 oz/A
    • Simazine 64 oz/A
    • NIS
  • Bump up Simazine and go in February for better rye poa control.
  • Finale – Best control especially if SU and glyphosate resistant poa.
  • Tribute Total – Excellent control as long as no SU resistance.
  • Monument – Fair
  • Sureguard – Inconsistent during this trial.
  • Revolver – Excellent
  • Kerb – Good, go early. Late fall, early winter.

Mini Ring Research Update

The research work Clemson and NC State are doing investigating the effects of fertilizer source type on the impact of mini ring was very interesting. In a nutshell it appears that urea based nitrogen sources have a very positive impact on the reduction of mini ring incidence versus using ammonium sulfate based products.

I certainly do not have room to elaborate on the outcome of the entire trial in this blog but the initial results of this study look very promising, with one more year of evaluations left in the study.

Lots going on to keep everybody busy at the moment, just wanted to pass along some great information shared at Clemson Field Day for those who may have been unable to attend.

All the Best Folks!
