Aphids have arrived!
It’s time to scout for Soybean Aphids as our agronomists and sales team have already seen some this season in Iowa, South Dakota, Wisconsin and Minnesota. It’s important to check fields early and often. Take aphid counts every 7 to 10 days to get a good idea of what the population is doing. Take counts at several locations throughout the field and count 20 to 50 plants per location. The economic threshold for aphids is 250 per plant.
