According to the growing degree day model, peak moth flight of MRB was reached on July 15th in Culver/Madras area, and will be reached July 23rd. Moth counts in the Culver/Madras area decreased from an average of 4 moths/trap on July 11th, to 3 moths/trap on July 18th. This indicates the model prediction is in line with what we are finding in the field.
There was a minor increase in moth counts this week in the Powell Butte area. We continue to find alfalfa loopers in the field and small populations of cutworms. Continue scouting your own fields to make management decisions. If control is needed, now is the optimal time to apply Coragen for control of MRB, loopers and cutworms in the Culver/Madras area. See newsletter for more information.

Adult MRB counts in pheromone traps are picking up, with some sites at 8/trap while others remain at less then 5/trap. Reports in Central Oregon are also finding areas with increased MRB flight activity. Alfalfa loopers are showing up more frequently in sweep net samples, so please continue to scout fields over the next week to determine if populations are increasing in your fields.
