Southern rust has been confirmed in corn in three eastern Nebraska counties this week. Corn fields should be scouted soon and frequently in the coming weeks for this and other diseases in case treatment is necessary.
Learn how to examine plant development and use this forensic strategy to determine the approximate calendar date when the plants in your field were likely exposed to dicamba.
There are now five structurally different growth regulator herbicides, each of which affects plant growth differently. Understanding the differences can help you better identify the cause when you find damage in your field.
With much of the state's soybean crop soon entering pod stages, it's time to scout for frogeye leaf spot. This guide and video address scouting and management.
Come see the results of this year's replicated soybean research and hear from presenters on cover crops, marketing, weed, insect and disease management, and much more. Programs will be at four sites in partnership with the Nebraska Soybean Checkoff.
Crops Research

While it was built on a foundation of basic plant science, research at the Center for Plant Science Innovation is anything but basic. Edgar Cahoon, center director, believes the ability to bring findings to the field is what makes the work unique.

After the Storms

Following a hail event, crop canopy development can be severely delayed or damaged, which can lead to increased weed development and pressure. This story looks at factors to consider when selecting among mid-season weed control options in storm-damaged fields.
If you were hit hard by hail and need to cover your fields, forage cover crops can provide an opportunity for haying or grazing as well as a protective plant layer. Plant selection is a key factor in successfully managing production.

Fields that were hailed, flooded, windblown, or where planting was prevented this season can benefit from the many soil services provided by cover crops. In addition a growing cover crop can help reduce erosion from water and wind and may help protect soil moisture levels.
Dry Beans

A recent study of 10 years of research in key dry bean production areas of the US and Canada showed the value of weed management. Without weed control losses were estimated at $720 million.
This week's topics: Corn, soybean and wheat markets; determining dicamba soybean injury occurrence, 18th Annual Nebraska Grazing Conference, Palmer amaranth research, and the weather outlook for the coming week.
Corn silking was 65%, well ahead of 42% last year and 38% for the five-year average. Condition was 86% good to excellent.Soybean blooming was at 65%, ahead of the average of 53%. Condition was 83% good to excellent.
