Seedling Diseases Developing in Corn May 20, 2016

With cool wet conditions favorable for corn seedling disease development, growers are urged to scout for inconsistent stands and disease pressure. This week seedling diseases were documented in 10% of surveyed fields in Dodge County in eastern Nebraska, mostly in corn-after-corn fields in river valleys. Be sure to monitor seedling emergence and stand establishment across the state during the coming weeks so that if problems occur they can be detected as early as possible.

Why are Emerged Corn Seedlings Yellow? May 19, 2016

The yellow hue to corn seedlings reported in multiple fields this week may be indicative of several conditions, but is likely due to the cool wet weather plants have experienced since emergence. The symptoms do not necessarily point to a nitrogen or potassium deficiency which may also cause a yellow hue. In addition, corn seedlings subjected to water-saturated soils, soil compaction, and certain herbicide applications may appear yellow.

How Saturated Soils Affect Germination, Seedling Growth May 12, 2016

Similar to last year’s heavy rains in early May, rain on May 9 and May 10-11 in portions of Nebraska have caused ponding and flooding across some fields.  As of Sunday, May 8, USDA-NASS reported that 57% of Nebraska's corn was planted that is behind the 71% planting progress in 2015 but close to the

Hail Damage in Corn May 11, 2016

Yield losses from hail storms will depend on the timing and severity of the hail, and subsequent environmental conditions. Regardless of the level of damage, farmers should be patient when evaluating early-season hail damage in corn and wait 7–10 days after a hail event to allow for crop regrowth. See more on replant decision, yield potential of surviving plants, hail and bacterial plant pathogens.

Wet Conditions Favorable for Seedling Diseases in Early Planted Corn April 28, 2016

Wet field conditions and cool soil temperatures across Nebraska may put early planted corn at added risk for seedling diseases. Be sure to monitor seedling emergence and stand establishment in the coming weeks so that if problems occur they can be detected as early as possible.
