Detection and Characterization of the Causal Agent for Bacterial Leaf Streak in Corn
July 7, 2017
When a new crop disease strikes, researchers dig in to identify its characteristics. Noting how it's similar to and different from other diseases are part of defining it so plant pathologists can better confirm its presence in the field, monitor its spread, and develop appropriate management practices. Here's the story of how plant pathologists identified bacterial leaf streak.

Recent Cold, Wet Conditions are Favorable for Seedling Diseases in Early Planted Corn
May 5, 2017
Recent cold, wet field conditions and fluctuations in soil temperatures have put early planted corn at risk for seedling disease development. Cold soil temperatures and episodes of recent rainfall (and snow) are especially favorable for some of the most common and damaging seedling diseases favored by cold wet conditions.
Update on Bacterial Leaf Streak of Corn in Nebraska
February 23, 2017
Bacterial leaf streak was first confirmed in the US in August 2016 when it was identified in Nebraska corn. It has now been confirmed in 51 Nebraska counties and found in corn fields across the Midwest. This article offers information on current status, identification, and management of the disease. Resistance is not currently available in hybrids and standard management measures of bacterial diseases will help mitigate but not eliminate damage.
