Plain language summary
This reported summarized soybean field trial data collected in 2020 examining the effects of using seed treatments that protect seedlings from disease and the density of seed plated to determine the best combination for yield and revenue. Overall the highest yields were obtained by planting the most seeds, but the cost of seed at these high seeding rates were not profitable. Certain seed treatments protected the soybean from disease and helped maintain a higher population than other treatments. It was found that seed treatment Apron XL was the best for both yield and revenue at moderate planting rates this year, probably due to increased damping off disease caused by Pythium that this treatment is effective at controlling. Severe drought conditions in 2020 likely contributed to more disease pressure.
