Aphid Speed Scout

Speed scouting is a different way to determine if soybean aphids have reached the 250 aphids per plant threshold. It relies on the number of "infested" plants. Plants are considered "infested" if there are 40 or more aphids on that sample. No more having to try to count all the aphids on a plant to determine whether it has reached the threshold of 250 aphids per plant. This helps you quickly determine — yes or no — whether the plant has 40 aphids and would be considered “infested.” It then recommends further scouting or treatment options based on the number of “infested” plants in a given area.
