May 10, 2024 | CropWatch | University of Nebraska–Lincoln
Alfalfa weevil larvae have emerged in southeast, south-central and central Nebraska; scouting for this pest is crucial for alfalfa producers over the next few weeks.
For concerns regarding the use of chlorpyrifos on crops during the 2024 growing season, producers should contact their local extension educator for assistance.
The appearance of wheat disease has increased in Nebraska, with new observations of stripe rust in several counties and low levels of barley yellow dwarf and leaf spot diseases.

This short program will include a roller crimper demo, discussion on what conditions must be met to be successful with this termination method, and insights from farmers on their experiences with crimping.
Research Updates
Three Nebraska Extension NebGuides have been updated to include information about the new UNL Nitrogen Tool, designed to increase efficiency of nitrogen use in crop production.
The updated publications provide information about UNL's newly developed web-based nitrogen (N) recommendation tool for corn grain, adapted from extension's previous N recommendation equation.

Below-average precipitation and an increased need for irrigation have led to groundwater level declines of more than 20 feet at some locations in Nebraska.
Crop Reports
Historical crop progress data for Nebraska is available at USDA.
Nebraska Extension Educator Gary Stone shares the weekly crop water use outlook and tips on preparing for the 2024 irrigation season.
Forage Production
For pastures with noxious weed thistles like this musk thistle, now is the time for spring herbicide applications, while the plants are still in the short rosette to bolted growth stages prior to flowering. (Photo by Gary Stone)
Insights on pasture rental rates, selecting summer forage based on needs for your operation, and control options for noxious weed thistles in pastures.
This webinar reviews the pros and cons of adding an annual forage into crop rotations, with insights from Mary Drewnoski, extension beef systems specialist, Jay Parsons, extension farm and ranch management specialist, and Daren Redfearn, extension crop residue specialist. (USDA NRCS photo)
This webinar highlights the economics and production benefits of incorporating annual forage systems into crop rotations for producers interested in diversifying their operation.

Gary Peterson, Colorado State University professor emeritus, delivered the opening keynote presentation at the Nebraska Soil Health School held at UNL’s High Plains Ag Lab on April 24. Peterson outlined historical events and mismanagement practices that have degraded the Great Plains soil and discussed the how and why the coupling of reduced tillage and cropping intensification can help growers rebuild soil.

The first Nebraska Soil Health School of the year was designed to provide potential management practices for producers in the Panhandle, with one focus being the practicalities of growing cover crops in semi-arid regions.
The National Center for Resilient and Regenerative Precision Agriculture at Nebraska Innovation Campus will be a $160 million USDA laboratory, enabling USDA ARS to perform research on wheat, barley, sorghum, forage and bioenergy grasses, and other crops. Research on how these plants respond to emerging pests and pathogens under a full range of environmental conditions will empower scientists to make cutting-edge discoveries with the goal of developing climate-resilient crops for the U.S. agriculture industry.

The state-of-the-art research center will house USDA ARS studies on the impact of emerging pests and pathogens on crops with the goal of developing climate-resilient crops for the U.S. agriculture industry.
Weather

There is more rain expected for Nebraska next week, but it's likely to be followed by an extended dry period.
Land Management
Attendees of Land Management Quarterly can submit questions to the presenters prior to the webinar using the questionnaire form on the Land Management Quarterly website (link in article).
The May 20 webinar will examine the latest average cash rental rates in the state, how to adjust rental rates with regard to current commodity prices, and will include a Q&A session for participants.
