By using a degree-day model, growers can account for the effect of temperature on insect development and approximate when certain insect stages will occur. See predicted cutworm flights and recommended scouting periods for 14 Nebraska locations.
Ponding or flooding of fields affects corn differently at different stages, depending on duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.
Figure 1. The degree of damage from standing water in this field will depend on several factors and likely will lead to direct yield losses or indirect losses from increased disease pressure.
Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.
Corn around V10-11 with leaves stripped due to hail damage. In this case, much of the corn will recover and look better in 10-14 days. Watch stalk bruising to see if stalk rot sets in. There are fields with hail damage at lower stalks with weakened plants that easily break. Soybeans at R1 (beginning flowering) reduced to sticks north of Stromsburg and in Hordville area. Soybeans with damage like this at the R1 stage can have the greatest yield loss in spite of seeing new buds regrowing with the warm weather. Another concern will be weed control going forward.

When severe storms and hail hit your corn and soybean fields, it's important to estimate yield losses to determine the need for future inputs and alternative management strategies. This guide offers steps to evaluate mid-season hail damage and estimate potential yield losses.
In the last 20 years Brazil has emerged as a major player in the world's corn market and is now the second largest exporter and third largest producer, challenging US dominance. This week's Cornhusker Economics takes a closer look.
Wheat Production

Wheat diseases were found at varying levels across a wide area of fields surveyed this week in western Nebraska in conjunction with the 2018 Wheat Tours.
Final results from the Nebraska Farm Real Estate Survey show a fourth consecutive year of declining Nebraska agricultural land values. The statewide average value dropped 4% to $2,270 per acre.
Reciprocity can be a powerful persuasive tool in negotiations, but it also can be misused and lead to emotional rather than well thought-out responses. Learn how to recognize when reciprocity is being used and when to integrate it in your negotiations.
Due to recent rains, growers may be seeing an increase in "windrow disease,” typified by a striped appearance in fields where alfalfa windrows remained so long that regrowth is delayed.
After wheat harvest, don't let your ground stand idle, especially if you could use more forage. When moisture is available, there are a number of forage options to consider following wheat.
This project will demonstrate how subsoil injection of an abundant carbon source (recycled sawdust and wood shavings) will establish a biologically active layer for interception and removal of dissolved nitrate after it has left the crop root zone.
Jenny Rees reports on crop progress and shares a video on determining approximate timing of off-target dicamba movement and Megan Taylor reports on crop progress in northeast Nebraska.
