| Florida Bears and Beekeeping (ENY105/AA133) The Florida black bear (Ursus americanus floridanus) is a minor predator of beehives in Florida with the potential to cause major destruction. Large-scale urban and agricultural development inexorably reduces prime bear habitat each year. This habitat also contains excellent bee forage, and so bears and bees will sometimes come in contact, thus resulting in bear predation. This 4-page fact sheet was written by Malcolm T. Sanford and James D. Ellis, and published by the UF Department of Entomology and Nematology, August 2012. | |
|
| Bottling, Labeling and Selling Honey in Florida (ENY159/IN918) In 2011, the Florida Legislature enacted HB 7209 allowing individuals to manufacture, sell, and store certain types of “cottage foods” (including honey) in an unlicensed kitchen. “Cottage food operations,” as they are called, require no licensing or permitting from the Florida Department of Agriculture and Consumer Services and are not inspected by any other state government entity. This 4-page fact sheet was written by Nancy Gentry and James D. Ellis, and published by the UF Department of Entomology and Nematology, August 2012. | |
|
| Florida Reclaimed Phosphate Mine Soils: Characteristics, Potential Uses, and Management Considerations (SL370/SS571) A critical nutrient for plant growth, phosphate helps sustain the world’s growing population. In 2010, seven mines in Florida produced approximately 10% of the world’s phosphate supply and more than 65% of the phosphate for the United States. But each year in Florida thousands of acres disturbed by strip-mining for phosphate rock must be reclaimed for other productive uses. This 11-page fact sheet provides a general characterization of the various soil types resulting from phosphate mine reclamation. Written by M. Wilson and E.A. Hanlon, and published by the UF Department of Soil and Water Science, October 2012. | |

|
| Florida Crop/Pest Management Profiles: Snap Beans (CIR1231/PI032) In 2009-2010, Florida growers produced 193.2 million pounds of snap beans, with a value of $0.69 per pound and a total value of $135 million. Snap beans were planted on 36,400 acres, and 32,200 acres were harvested, yielding an average of 6,000 pounds per acre. This 18-page fact sheet was written by W.M. Elwakil and Mark A. Mossler, and published by the UF Department of Agronomy, October 2012. | |
|
| Pepper Fruit Fly Atherigona orientalis (Schiner) (Insecta: Diptera: Muscidae) (EENY539/IN948) Although it is commonly referred to as the pepper fruit fly or tomato fruit fly, Atherigona orientalis is not a true fruit fly in the family Tephritidae, but rather a member of the Muscidae, the same family to which the common house fly belongs. It is found in most tropical and subtropical areas of the world and is usually considered a secondary pest or “trash fly.” But it can sometimes be a primary pest of certain agricultural crops, most notably plants in the family Solanaceae. This 4-page fact sheet was written by Kenneth L. Hibbard and William A. Overholt, and published by the UF Department of Entomology and Nematology, September 2012. | |
|
| Fertigation for Vegetables: A Practical Guide for Small Fields (HS1206) More and more farmers are growing small crops of fruits and vegetables for specialty local markets. They commonly grow several crops at different stages of development at the same time so they have a variety of produce to sell to customers. This forces farmers to make several fertilizer calculations because of their diverse crop demands, because water and nutrient requirements vary according to the crop and stage of development. This 7-page fact sheet helps growers correctly interpret fertilizer recommendations and calculate accurate fertilizer amounts to be used based on crop nutrient requirements. Written by Jim DeValerio, David Nistler, Robert Hochmuth, and Eric Simonne, and published by the UF Department of Horticultural Sciences, October 2012. | |
|
| Salmonella and Pathogenic E. coli in the Crop Production Environment: Potential Sources, Survival, and Management (SL375/SS576) Over the last two decades, at least a dozen major outbreaks of gastroenteritis caused by non-typhoidal Salmonella or enterovirulent E. coli have been linked to the consumption of sprouts, nuts, and fresh (or minimally processed) fruits and vegetables. These outbreaks caught scientists and the public off guard because these pathogens were not previously considered “plant-associated.” This 3-page fact sheet highlights recent discoveries that focus on the ecology of human pathogens in the crop production environment. A better understanding of how pathogens persist outside of animal hosts in agricultural water, soils, and plants will have major impacts on managing produce safety from “farm to fork.” Written by Max Teplitski, Andree George, and George Hochmuth, and published by the UF Department of Soil and Water Science, October 2012. | |
| Citrus | ||
|
| Fortunella spp., Kumquat (FOR300/FR368) Many people find kumquat trees attractive and useful yard specimens. Their dark green leaves and contrasting bright orange fruits give them ornamental quality, and their relatively small size makes them easy to care for once they’re established. Because kumquats generally require less care than other citrus trees, they may be a good choice for gardeners with less time or experience, but who still desire an attractive and tasty citrus tree. If space is an issue, kumquats also do well in containers as long as they receive proper sunlight and watering. This 2-page fact sheet was written by Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop, and published by the UF Department of School of Forest Resources and Conservation, July 2012. | |

Cantliffe, and published by the UF Department of Horticultural Sciences, October 2012. | |
| Livestock | ||
|
| Self-Treatment Methods for Livestock–Backrubbers (ENY279/IG134) Back rubbers are a method of pesticide self-treatment for cattle. When bothered by insects or other pests, cattle tend to rub against objects. Backrubbers provide a rubbing surface that is treated with a pesticide. Cattle self-treat during rubbing, which reduces the number of flies, particularly horn flies, and parasites such as lice, on the animal. Backrubbers may be purchased commercially or constructed from easily available materials. A properly designed backrubber that supplies pesticide reliably to the animal can be a valuable addition to an integrated pest management program. This 4-page fact sheet was written by E. N. I. Weeks and P. E. Kaufman, and published by the UF Department of Entomology and Nematology, September 2012. | |
|
| Horn Fly Management (ENY288/IN952) Horn flies are one of the livestock pests with the greatest impact on the health and productivity of cattle. Economic losses due to horn fly damage are estimated at $36 million annually in Florida alone. In the U.S.A. annual losses total between $700 million and $1 billion, with up to $60 million spent on insecticidal control. Horn fly damage is caused by blood feeding. The flies feed frequently and exclusively on blood, piercing the skin of cattle with their proboscis and taking around 20 small blood meals each day. Pain and irritation due to the constant presence of the flies and their bites causes defensive behavior in the cattle that prevents adequate food consumption and rest. This 4-page fact sheet was written by P. E. Kaufman and E. N. I. Weeks, and published by the UF Department of Entomology and Nematology, September 2012. | |
|
| Carbon Sequestration in Grazing Land Ecosystems (SL373/SS574) Native and improved pastures play an important role in sequestering carbon from the atmosphere. Because of the relatively high sequestration rates and extensive area, grazing land represents an important component of terrestrial carbon dioxide (CO2) offset and is a significant sink for long-term carbon sequestration and greenhouse gas mitigation. This 4-page fact sheet contains information for stakeholders, students, scientists, and environmental agencies interested in enhancing ecosystems services provided by grazing lands. Written by Maria Silveira, Ed Hanlon, Mariana Azenha, and Hiran M. da Silva, and published by the UF Department of Soil and Water Science, September 2012. | |

| Comparing the Urine Ketone Strip Test and Handheld Ketone Meter to Diagnose Ketosis in Early Lactation Dairy Cows (VM186) Ketosis is a common metabolic disease in fresh dairy cows. Clinical and subclinical ketosis (SCK) can cause reduced milk yield, decreased milk protein, reduced reproductive capacity, and increased risk of displaced abomasum. Usually, diagnosing ketosis is performed by measuring acetoacetate or BHBA levels in the blood, urine, or milk samples. Measuring BHBA in serum or plasma is considered the gold standard diagnostic test for subclinical ketosis, because this method has stability, but the price for ketone strips is approximately $0.08/strip while the price for the electronic BHBA measuring system is approximately $1.00. UF/IFAS researchers conducted a study to compare the two, using 72 Holstein cows between 14–40 days in milk from three dairy farms in north-central Florida with 450–800 lactating dairy cows. The key finding for this experiment is that no difference exists in BHBA concentration between cows that had a trace or small in the ketone strip reading. This 3-page fact sheet was written by Klibs N. Galvão, Achilles Vieira Neto, Gustavo Peña, Joao Bittar, and Lucas Ibarbia, and published by the UF Department of Veterinary Medicine-Large Animal Clinical Sciences, October 2012. | |
