This week on SUNUP: 

• Maira Duffeck, OSU Extension field crops pathologist, says Southern rust is showing up in corn fields. Dr. Duffeck explains how to identify this disease and ways to manage it.
• Brian Arnall, OSU Extension soil nutrient management specialist, discusses how Oklahoma’s sorghum crop is looking and says nitrates could become an issue for livestock producers. Dr. Arnall also has information on the upcoming Sorghum Experience Oklahoma event.
• In the Mesonet Weather Report, Emma White shows how the recent heat wave is impacting the cattle comfort index. State climatologist Gary McManus says the drought picture is still looking good, but the consecutive days without a good amount of rainfall are adding up.
• John Michael Riley, OSU agricultural economist, says both trade policy and extreme heat have caused issues in the corn market, but recent national rains have helped settle things to an extent.
• SUNUP previews the upcoming 2025 Women in Agriculture Conference.
• In Cow-Calf Corner, Mark Johnson, OSU Extension beef cattle breeding specialist, discusses foxtail and how that plant can overtake a pasture and outcompete desirable forages.
• SUNUP viewers are encouraged to check out the next Rancher’s Thursday Lunchtime Series live webinar on July 31. Topics include grazing and management at Pickle Farms in LeFlore County, as well as approaches to change grazing distributions and forage quality in native grass.
