I observed the cotton aphid fungus in some of the cotton fields I visited this past Friday in Brooklet, Portal, Statesboro and Stilson. It looked like it was just getting started, so hopefully many of the fields with high aphid numbers will crash this week. Some fields have been sprayed due to the discoloration of the terminals and the presence of aphids in the whole field instead of them being just in hot spots. Notice the presence of gray, fuzzy aphid cadavers in the picture below that I took Friday that is indicative of the fungus. Hopefully, the fungus will continue to build and aphid populations will crash soon.
