Branch Dieback of Syzygium paniculatum (Eugenia) (PP283)
Eugenia’s popularity stems from its dense, attractive foliage, the ease with which the canopy can be sculpted, and its relatively carefree management. But shortly after Hurricane Wilma in November 2005, a serious dieback disease began to affect nursery production of eugenia in the Homestead area. Since then, the disease has become prevalent, affecting local nurseries throughout South Florida. Learn more about this disease and its management in this 4-page fact sheet written by A. J. Palmateer and T. L. B. Tarnowski, and published by the UF Department of Plant Pathology, July 2011.

Importance of Milk Feeding Pre-weaning to Dairy Calves (AN263)
Similar to any mammal, newborn dairy calves must consume milk in the first weeks of life because of their inability to properly digest dry feeds. On most dairy farms, milk harvested from cows or reconstituted milk replacer powder provides the primary source of nutrients for calves in the first 4–6 weeks of life before they are able to adequately digest other feeds.

Terrestrial Slugs of Florida (Mollusca: Stylommatophora: Veronicellidae, Phylomycidae, Agrolimacidae and Limacidae) (EENY494/IN891)
Most slugs are hermaphroditic, possessing both male and female sex organs. This makes slugs particularly dangerous as invaders because even a single individual that escapes detection can establish a population in a new environment through self-fertilization. This 11-page fact sheet discusses the slug situation in Florida, including problems with slug identification and taxonomy, as well as the behavior, ecology, and management of slugs.
