Phytophthora root and stem rot in soybeans and bacterial leaf streak and common rust in corn were among the most common diseases reported in the last two weeks by the UNL Plant and Pest Diagnostic Clinic.
Earlier this week south-central and central Nebraska were hit by heavy rains leading to flooding. Now farmers are asking: How long will the crop survive in standing water and what does this mean for the rest of the growing season?
Producers, consultants, and agronomists should be alert to the potential for increased disease pressure in fields that experienced flooding in March or more recently. Here are some of the diseases you're most likely to see.
Western corn rootworm beetles began emerging in southeast and south central Nebraska and will feed on corn leaves until silks, their favored food, emerge. Beetles will emerge somewhat later in northeast and western Nebraska.
The Nebraska Extension Circular, Nutrient Management Suggestions for Corn (EC117), has been updated to account for residual soil nitrate-N and provide an alternative for determining fertilizer-P rates.
Agronomists address how the Corn Yield Forecast Center develops yield forecasts, what to expect during the growing season, and how to use the forecasts to inform farm decisions. Tables detailing soil types and crop management for each of the 41 locations are included.
Corn is considered a cover crop species in Nebraska and can be planted into prevented planting acres and can be grazed or harvested for forage. See these NRCS recommendations for meeting guidelines when using corn as a cover crop.
Corn nematodes, bacterial leaf streak, and frogeye leafspot, oh my! Extension Plant Pathologist Tamra Jackson-Ziems returns to the Nebraska CropWatch Podcast with information on mid-season corn and soybean diseases.
