Peanuts And Valor Injury

We plant a lot of peanuts on plantations here in Thomas County. As we were finishing up peanut planting, manager at Wild Ridge Plantation Jason Sanders made a great video of them planting near the Florida line. They filmed it with a drone camera. Jason did a great job making this video. I think I need to get my ‘video band’ down to Wild Ridge and get a band shot from this drone camera.

Our peanut crop is looking good since we’ve had a few weekly rains. Fungicide programs are starting up now, and we’re still needing some rain. We had a few showers this week, but not much to count. UGA Extension Weed Scientist Dr. Erick Prostko has this update on valor that I want to share:

Peanuts that were planted approximately the last two weeks in May were in a great place to get hammered from Valor because of the Sporadic heavy rainfall events (below).  If you received one of these heavy rainfall events on Valor treated peanuts when they are cracking and small (~2 weeks after cracking), injury will occur.

 Peanuts typically recover from this injury without a yield penalty.  In a 2009 research trial, more than 5″ of rainfall occurred in the 30 day period after peanut planting.  Peanut injury was significant but yields were not reduced even at a 2X rate.
