Marcelo Wallau shares the latest updates on pasture mealybug and its growing impact on forage production across Florida.

As researchers work to better understand the pest, this episode highlights emerging strategies to improve long-term resilience.
In this episode of Cow Talks, host Marcelo Wallau sits down with Dr. Dean Pringle, the new chair of the University of Florida Department of Animal Sciences, to talk about his plans for the department, including a stakeholder-driven strategic plan. Dr. Pringle introduces the Animal Products Excellence Center (APEX), a revitalized meat science hub meant to connect genetics, nutrition, and management on the ranch to the Florida consumer.
In this episode of Cow Talks, host Marcelo Wallau is joined by Dr. Clyde Fraisse, professor of agrometeorology in UF's Agricultural and Biological Engineering Department, to break down the strong El Niño forming in the Pacific and what it could mean for Florida this fall, winter, and spring. They discuss the higher odds of above-average rainfall along with why this may be a good year to invest in cool-season forages.
Marcelo Wallau talks with a panel of industry agronomists and nutritionists about growing corn and sorghum silage in the Southeast. They cover this season's challenges, such as late frosts, dry weather, nematodes, and the tight timelines dairies work underm and what those mean for fiber digestibility. The group also discusses where sorghum fits in the rotation and why hybrid selection matters less than solid management and a good crew.
In this Cow Bites technical segment, host Marcelo Wallau sits down with Maria Elena Mailhos, variety trial coordinator for the UF/IFAS Forage Team, to walk through the results of the 2025–26 cool-season forage variety trials.Trial results, reports, and the three-year regional recommendations (developed with the University of Georgia and Auburn University) are available on the UF/IFAS Forage Team website: https://programs.ifas.ufl.edu/forage/official-variety-trials/Questions? Reach the team at forages@ifas.ufl.edu, or come see the varieties in the field at the annual cool-season forage field day in late February.
Crop insurance is an increasingly important tool for managing the production and price risks facing farmers and ranchers. In this episode, Dr. Hunter Biram of the University of Arkansas breaks down how federal crop insurance works and how it complements Farm Service Agency programs. The episode dives into discussion about what producers should know about coverage options. The conversation also explores Pasture, Rangeland, and Forage (PRF) insurance, livestock risk protection, basis risk, and how cattle producers can use these programs to manage production challenges.The links to the workbook and Hunter's podcast can be found below:The Fundamentals of Federal Crop Insurance: https://www.uaex.uada.edu/publications/pdf/MP576.pdf Morning Coffee and Ag Markets Podcast: https://fryar-risk-center.uada.edu/podcast/
Hannah Baker speaks with Dr. Marcelo Wallau about the latest pressures facing the U.S. beef cattle industry, from the announcement of increased beef imports to the reopening of the Mexican border and recent beef packing plant closures. They discuss how these developments are affecting cattle prices and decisions about herd rebuilding. Given the market turmoil, producers are left navigating a great deal of uncertainty, which this episode aims to clarify.
Pasture mealybug continues to spread across Florida, with new detections raising questions about how the pest is moving and why damage is appearing in some pastures but not others. In this update, Dr. Brent Sellers and Dr. Isaac Esquivel discuss the latest field observations, early detection, insecticide use, and strategies for managing affected pastures during the stockpiling season. They also share emerging findings and highlight the many questions researchers are still working to answer.
