Corn and Grain Sorghum Weekly Update – July 19, 2019
Author: Chuck Capps, Corn and Grain Sorghum Research Verification Program Coordinator

By Chuck Capps, Corn and Grain Sorghum Research Verification Program Coordinator

Fields received anywhere from 3.5” of rain to over 7.5” from the tropical storm.  Needless to say, we didn’t need irrigation.  We are using the growth stages from the fields that are nearing maturity and available soil moisture to see how much more water we will need to reach irrigation cutoff.  With fields being fully saturated this past Tuesday from storm, we can subtract about 1.5” of water needed that I calculated Thursday (7/18) to finish out the crop. A couple of the younger fields are still using about 0.3 inches of water per day.  

I am still getting some Southern rust questions especially on the later planted corn, so I have attached Extension Plant Pathologist, Dr. Travis Faske’s Disease Update for your information below the crop updates.  Most fields are beyond where diseases can affect yield significantly.  We will continue to scout younger fields were a fungicide might still be needed with disease presence and favorable conditions for development.
