| What is a Water Footprint?: An Overview and Applications in Agriculture (AE484)
Agriculture is by far the largest global consumer of freshwater. Comparing water footprints of different management practices in agriculture can help evaluate drought tolerance, water use efficiency, the effective use of rainfall, and the significance of irrigation. Scientists are thinking about ways to adapt agricultural systems to a changing climate, especially precipitation changes, so the water footprint is a useful measure to compare resilience of agricultural systems to droughts and dry spells. This 11-page fact sheet was written by Daniel R. Dourte and Clyde W. Fraisse, and published by the UF Department of Agricultural and Biological Engineering, January 2012.

| Economic Potential of Switchgrass as a Biofuel Crop in Florida (FE900)
Switchgrass has been recognized by the United States Department of Energy as a potentially important source of ethanol. This publication evaluates the economic potential of producing switchgrass as a perennial bioenergy crop in Florida. In South Florida, two cuts of “hay” for biofuel are possible, whereas in North Florida, one cut would normally be taken after frost in late fall. These two harvest systems are evaluated and compared, and cost estimates are provided. This 7-page fact sheet was written by Zane R. Helsel and José Álvarez, and published by the UF Department of Food and Resource Economics, December 2011.

| Florida's Commercial Blueberry Industry (HS742/AC031)
The Florida blueberry industry has grown rapidly because Florida growers can produce high-quality fruit when few fresh berries are available and berry prices are high. Although southern highbush blueberry acreage has expanded significantly in Florida, Georgia, California, and Mexico during the last several years, better cultivars and improved cultural practices have increased grower production efficiency during the last several years, with promising production trends for the future profitability. This 4-page fact sheet was written by J. G. Williamson, J. W. Olmstead, and P. M. Lyrene, and published by the UF Department of Horticultural Sciences, February 2012.

| Mexican Fruit Fly, Anastrepha ludens (Loew) (Insecta: Diptera: Tephritidae) (EENY201/IN358)
The Mexican fruit fly is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. It is a frequent invader in southern California and Arizona. Mexican fruit fly represents a particular threat to Florida because of its special affinity for grapefruit, of which Florida is one of the world’s leading producers. Mexican fruit fly larvae are transported widely in infested fruits. This 6-page fact sheet was written by H. V. Weems, Jr, J. B. Heppner, G. J. Steck, T. R. Fasulo and J. L. Nation, and published by the UF Department of Entomology and Nematology, January 2012.

| GAPs for the Florida Citrus Grower: Understanding the Principles of Good Agricultural Practices (FSHN1203/FS187)
Growers are the first step in the farm-to-table food chain. Good Agricultural Practices (GAPs) refer to practices growers follow to prevent, minimize, or eliminate contamination and hazards to human health. Essential components of the GAPs process include careful planning, implementation, and documentation of required steps and procedures that together analyze and minimize risks imposed by biological, chemical, and physical hazards. The general guidelines presented in this document were developed by UF/IFAS for Florida citrus growers, in partnership with the citrus industry. This 8-page fact sheet was written by Michelle D. Danyluk, Renée M. Goodrich-Schneider, Keith R. Schneider, Mark A. Ritenour, and Timothy M. Spann, and published by the UF Department of Food Science and Human Nutrition, February 2012.

| Citrus Diseases Exotic to Florida: Mal Secco (PP290)
Mal secco, Italian for “dry disease”, is a fungal disease that causes serious damage to a number of citrus cultivars in the Mediterranean and Black Sea areas, but has not been reported in other citrus-growing regions. The main diagnostic field symptom is that wood of affected limbs has a reddish-yellow stain. This 3-page fact sheet was written by K.-R. Chung, and published by the UF Department of Plant Pathology, February 2012.

| Citrus Diseases Exotic to Florida: Satsuma Dwarf (PP291)
Satsuma dwarf is a virus disease that was first reported in the early 1930s in Japan. The disease causes serious problems in citrus because it reduces tree vigor and fruit yield. Satsuma dwarf has also been reported in mandarin-growing areas in China, Korea, and Turkey, where it was likely introduced through importation of infected budwood from Japan. This 2-page fact sheet was written by K.-R. Chung and R.H. Brlansky, and published by the UF Department of Plant Pathology, February 2012.

| Citrus Diseases Exotic to Florida: Citrus Yellow Mosaic (PP293)
Citrus yellow mosaic is an important viral disease in India, where it causes significant yield reduction. In some groves, infection rate may be as high as 70%. CYMV induces a bright yellow mottling or vein flecking that persists in mature leaves. Yields are sharply reduced in chronically infected ‘Sathgudi’ sweet orange trees in India, and fruit may also show mosaic symptoms. This 2-page fact sheet was written by K.-R. Chung and R. H. Brlansky, and published by the UF Department of Plant Pathology, February 2012.

| Control of Lantana in Pastures (SSAGR359/AG368)
Lantana is currently one of the top 10 most troublesome weeds in Florida. Although it is still sold as an ornamental, commercial varieties are sterile and considered to be non-invasive. It can quickly invade disturbed sites by producing plant toxins in its roots and stems, which either slow the growth of other plants or totally remove them. These leaf toxins are damaging to grazing animals. If animals consume the leaves, they often begin to show symptoms of skin peeling or cracking. Once animals show these symptoms, there is little or no treatment that can reverse the process. Although lantana’s leaves are poisonous, its berries are not. Birds readily consume the fruit and disperse the seed. This 2-page fact sheet was written by J. Ferrell, B. Sellers, and E. Jennings, and published by the UF Department of Agronomy, February 2012.

| Uterine Microbiology of Healthy Cows and Cows That Develop Uterine Disease (VM182)
The dairy cow is unique because virtually all cows are infected with bacteria right after calving. A recent study that used metagenomic analysis to characterize the uterine flora in healthy and metritic cows observed that most clone sequences from the metritic cows were from the phylum Fusobacteria. This 4-page fact sheet summarizes what is known about the pathogenic bacteria associated with metritis and endometritis. Written by Klibs N. Galvão and published by the UF Department of Veterinary Medicine-Large Animal Clinical Sciences, January 2012.

| Insecticides and Wildlife (ENY511/IN881)
When we use chemical insecticides to eliminate problem insects we discover that the effects of insecticides are not always limited to these 6-legged targets. Wildlife, pets, and humans also can be affected by insecticides. So one of the great challenges confronting humans is to develop ways to manage insects without affecting non-target organisms.
