Now is critical time to scout and make treatment decisions for soybean aphid in Iowa. But sampling whole plants during pod set and seed fill can be very time consuming! I created a sampling plan in 2005 called Speed Scouting for Soybean Aphid. It's a binomial sequential sampling plan that should save growers and crop consultants a lot of time out in the beans.
The Plant Management Network is offering a FREE webinar about how to use Speed Scouting. Visit the Focus on Soybean section under the Resources tab to view open access webinars, or simply click here. I spend about 15 minutes going over the sampling plan and show a few examples of how it works.
Go to my ISU faculty website to get blank Speed Scouting forms. I am interested in hearing about your experience with Speed Scouting. Tell me if you like it or even if you don't. There will be a tablet/smartphone app with Speed Scouting available for next summer.
