By Chuck Capps, Corn and Grain Sorghum Research Verification Coordinator
We found very low levels of Southern rust in the Corn Verification Field in Prairie County. Two leaves out of 100 total stops and very low on those two leaves. The field is about a week from black layer as well, so there is not much concern. Later planted corn will need to be scouted. The irrigation earlier this week for the Desha County Field will be its last. A couple more will be at irrigation termination next week.
We had to spray both Grain Sorghum Verification Fields for sorghum head worms this week. We have a very light infestation of sugar cane aphids in the Arkansas County Field near Casscoe. So, make sure to be scouting your grain sorghum especially the later planted fields. For field-specific information view the full report: CGSRVP Update 7-20-18
