Monday Musings (May 16) - Prostko

 A few things from the field earlier today:

1) When you get up early, you get to see some cool stuff!

Irrigating under the "blood" moon from last night (6:31 am)

Rainbows for breakfast!  A great omen for the rest of the week (hopefully).

2) Check out the awesome power of a PRE herbicide (activated with moisture).  These are from my grain sorghum plots.  It's 2 weeks after planting and in plots that are not weedy, there were PRE applications of various residual herbicides including one of the following: Aatrex (atrazine); Moccasin II Plus (S-metolachlor); Parallel (metolachlor); Everprex (S-metolachlor); Parallel Plus (atrazine + S-metolachlor); or Cinch ATZ (atrazine + S-metolachlor).  EPOST treatments were applied today. Not sure why growers, especially those with irrigation, are often reluctant to use a PRE??????????



3) Here's what diuron injury looks like on field corn.  It took 3 days before the symptoms started to show up.  I will let you know what happens to final yield.  

4) I am seeing some good weed control results in my soybean plots with Liberty + Enlist One (applied 19 DAP, V1 soybeans, 3-6" Palmer amaranth).


5)  Peanut growers who use Anthem Flex (carfentrazone + pyroxasulfone) in their paraquat "cracking" applications should expect to see more leaf injury (cosmetic) than when Dual Magnum, Outlook, Warrant, or Zidua are used.  Based upon previous UGA research, this injury should not reduce yields.
