Corn and soybean planting is almost done. As young plants start to emerge, growers will increasingly want to watch for pest and disease issues that could affect yield. An Iowa State University Extension field guide series is available to help farmers, agronomists and crop advisors quickly diagnose plant problems. The Iowa Soybean Association partnered with ISU Extension to produce the guides in 2008.Copies are available free from the ISU Extension online store.
