Scouting for soybean aphid the old-fashioned way, by whole plant count, is not easy. Accurately counting hundreds of moving aphids one by one to gauge potential
economic damage can be a tiring and difficult job.
The latest Focus on Soybean presentation discusses speed scouting: an easier, more efficient method of estimating whether aphids will have a significant economic impact on crops, helping the grower or consultant quickly decide if treatment is warranted.
Erin Hodgson, Assistant Professor and Extension Entomologist at Iowa State University and creator of the speed scouting method, offers a how-to lesson on speed scouting, as well as a review of the sampling plan for making treatment decisions. The presentation also includes some examples of possible treatment decisions and a new paperless way to sample.
