Growers once considered their soybean crop much simpler to manage than their corn crop. However, this philosophy is changing as management systems evolve and new pest challenges arise. For example, soybeans are now planted earlier, so seed treatment use has grown dramatically. Increasing soybean aphid problems mean that scouting and spraying may now be necessary. Spread of soybean cyst nematode, sudden death syndrome, white mold and other diseases has increased management requirements for soybeans. For these reasons, growers still taking a low management approach to soybean production are likely missing a significant opportunity to increase their bottom line.

The record shows that soybean yield increases have not kept pace with those of corn over the last 25 years. DuPont Pioneer is dedicated to accelerating the pace of soybean yield improvement, both to meet global demand for grain and grower needs for increased production efficiency. An industry-leading network of agronomists and researchers has been established across North America to help accomplish this goal. This team conducts studies in growers' fields and other research sites throughout the U.S. and Canada, including collaborative studies with university scientists.

The mission of DuPont Pioneer Agronomy Sciences is to help maximize grower productivity by delivering useful crop management information built on rigorous, innovative research. This booklet serves as an introduction to DuPont Pioneer agronomic research, with examples of recent research results in several key areas of soybean management. Additional reserach reports and crop management publications are available from your Pioneer sales professional and at We hope this extensive library of research-based agronomic information and the local expertise of our agronomists and researchers serve as valuable resources to help improve productivity in your soybean operations.
