Cotton Aphid Fungus In Bulloch County

By wtyson

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.

Video: Sclerotinia and Lygus in Seed Canola: Field Update with George Lubberts, CCA | Enchant, Alberta

Join Certified Crop Advisor George Lubberts for this Prairie Certified Crop Advisor (Prairie CCA) field update from Enchant, Alberta. In this 12th video of the series, George takes us into a seed canola field where the male rows have been removed and the female plants are filling pods. This video was taken in the third week of August 2025.

George discusses the early signs of sclerotinia stem rot, explaining how infection begins in the stem, impacts pod development, and leads to premature ripening. He also shares insights on lygus bug management, including timing of spray applications to minimize feeding damage and maintain seed size and quality.

With cool, damp summer conditions, George notes that while disease pressure is present, overall field health remains good. The crop is just beginning to show early seed colour change, signaling progress toward maturity.

Topics Covered:

•Sclerotinia stem rot identification and impact

•Managing lygus bugs in seed canola

•Crop stage and seed colour change observations

•Timing insecticide sprays for optimal protection

•Insights from a CCA field perspective in southern Alberta
