This week’s floods in south-central and central Nebraska have brought up questions about crop growth and development for the remainder of the growing season. One thing producers, consultants, and agronomists might want to consider is the potential for disease pressure in fields that experienced flooding this year. Corn and soybean progress varied widely across the area where flooding occurred. As the growing season progresses, scouting is going to become very important in fields affected by flooding. Several diseases are favored by flooded conditions and understanding field history, crop susceptibility, and weather patterns can help you anticipate which diseases are likely to occur later in the growing season.
This article looks at stalk rots, bacterial stalk rot, and crazy top in corn and brown stem rust, sudden death syndrome, and phytophthora in soybean and links to in-field videos for further information.
