This 13-page publication is meant to make calibration of boom sprayers easier, and therefore more common, by providing a convenient chart that can be kept in barns, tractor cabs, sprayers, and mix-load facilities for quick reference. Written by Michael J. Mulvaney, Pratap Devkota, Ethan Carter, De Broughton, and Mark Mauldin, and published by the UF/IFAS Agronomy Department, November 2020.
Determining when to dig is one of the most important economic decisions a grower must make. Peanut (Arachis hypogaea L.) poses a unique challenge for maturity determination because it is an indeterminate crop that forms pods underground. This 8-page fact sheet discusses maturity assessment methods as well as steps for collecting and evaluating a maturity sample. Written by Ethan Carter, Patrick Troy, Diane Rowland, Barry Tillman, Keith Wynn, Krystel Pierre, and Michael Mulvaney, and published by the UF Agronomy Department, September 2016.
The chicken mite affects egg-laying hens in many parts of the world, including Europe, Japan, China, and the United States. Although Dermanyssus gallinae affects birds in many regions, it is most prevalent in European countries, where egg industry losses are estimated at $177 million per year. It is a known vector for the St. Louis encephalitis virus, as well as other illnesses, such as fowl pox virus, Newcastle virus, and fowl cholera. In the United States, Dermanyssus gallinae is rarely found in caged-layer operations and is more commonly found in breeder farms. This 3-page fact sheet was written by Ethan Carter and Jennifer L. Gillett-Kaufman, and published by the UF Department of Entomology and Nematology, December 2015. (Photo credit: Lyle J. Buss, University of Florida)
