4-H Pizza Garden: An Agricultural Adventure

4-H cloverThis curriculum was designed for educators to teach young people about where their food originates by using something children love to eat…PIZZA! According to a recent Gallup poll, kids between the ages of 3 and 11 prefer pizza to all other foods for lunch and dinner. Americans eat about 100 acres of pizza each day, or 350 slices per second!This 4-H in the Classroom project, originating in Pinellas County, Florida, was designed for grades 3?5, but can be adapted to serve other grade levels. The lessons cover subject areas such as mathematics, social studies, language arts, and science. It has been used in Pinellas County very successfully since 2000 by the 4-H Program in collaboration with their Florida Ag in the Classroom Initiative. This 89-page fact sheet was written by Janet Golden, Joy Jordan, Nan Jensen, Betty Lipe, Millie Ferrer, Anne Fugate, Erin Karkheck, Linda Bobroff, Karla Shelnutt, and Tracy Tesdall, and published by the UF Department of 4-H Youth Development, November 2014.

Estimating Willingness to Pay for New Mandarin Cultivars: A Revealed Preference Approach

Credit: Sugar Belle citrus cultivar. Mix of sweet Clementine and Minneola varieties. UF cultivars, oranges, citrus. UF/IFAS File Photo. 07595SCalifornia has overtaken Florida to become the major US domestic mandarin producer. Despite a shift in consumer preferences toward the ‘Clementine’ mandarin that is widely grown in California, this cultivar is not well adapted to the subtropical climate of Florida. But in 2009, the University of Florida introduced the ‘Sugar Belle’, a cross between the ‘Clementine’ mandarin and the ‘Minneola’ tangelo. Survey test results showed that subjects preferred this new cultivar in terms of overall flavor, sweetness, acidity, and juiciness. survey test results showed that the Florida ‘Sugar Belle’ was preferred over the California ‘Clementine’ mandarin and the Florida ‘Murcott’ mandarin (aka Honey mandarin) in terms of overall flavor, sweetness, acidity, and juiciness. To determine consumer willingness to pay for specific attributes, UF/IFAS economists combined sensory evaluation and experimental auctions in a unique way, by comparing two different types of ‘Sugar Belle’ (SB1 and SB2) with the main competing product to identify the most desirable characteristics and to determine the best marketing and pricing strategy. This 6-page fact sheet was written by Xiang Bi, Lisa House, Frederick Gmitter, and Zhifeng Gao, and published by the UF Department of Food and Resource Economics, September 2014.

Screening Methods for Southern Chinch Bug Resistance in St. Augustinegrass

Figure 1. Bag test.Relying on insecticides for southern chinch bug control raises turfgrass maintenance costs, increases the risk that insects will develop resistance to insecticides, and may damage the environment. Host-plant resistance is a relatively sustainable and environmentally sound option for management of this damaging insect pest.To develop new resistant varieties, plant materials must be screened for new sources of southern chinch bug resistance. Screening methods to measure host plant resistance of St. Augustinegrass to southern chinch bugs have measured nymphal and/or adult survival in so-called no-choice tests in which only the experimental plant materials were provided. There are four types of screening methods described in this 4-page fact sheet was written by Huangjun Lu and Ronald Cherry, and published by the UF Department of Entomology and Nematology, October 2014.

Hand Pollination of Tomato for Breeding and Seed Production

Figure 2. Emasculation of the flower leaving the stigma exposed for pollination.Hand pollination is a technique that is used for breeding new tomato varieties with desirable characteristics such as plant vigor, disease resistance, and uniform fruit quality and plant growth; since tomatoes have complete flowers and are self-pollinated, it usually is unnecessary to hand pollinate the flowers for fruit production. This 4-page guide illustrates selection and emasculation of flowers from the plant receiving pollen, pollen collection and drying, and pollination of the stigma.

Economic Value of the Services Provided by Florida Springs and Other Water Bodies: A Summary of Existing Studies

Springs at Ichetucknee Springs State Park.  Water, vegetation, spring, nature.  UF/IFAS Photo by Tyler Jones.Florida residents and visitors place a high value on aquatic natural resources. This 8-page fact sheet reviews nine studies that demonstrate that Florida’s springs have a very large economic value, both for recreation and resource conservation. In these studies, economists measure the value of ecosystem services in dollar terms to assist management decisions concerning natural resources. Willingness to pay studies show that people who benefit from Florida springs place a high value on them. Economic contribution studies show that Florida springs play a significant role in local and state economic health and job creation.

Saddle and Tack Care in Hot and Humid Environments

Figure 2.  Particularly dirty saddles may be ?scrubbed? using saddle soap and water. A good rule of thumb for selecting a brush is to select one with plastic bristles that would be appropriate for cleaning your fingernails.The South’s climate is appealing for equestrian activities. While riders enjoy the weather, it creates some challenges in caring for saddles and other tack. When the weather becomes hot and the humidity climbs and the rains are frequent, a tack room can become a breeding ground for mold and mildew. There are several things a rider can do, however, to lower the incidence of mildew on saddles and tack.

Cat's-Claw Vine, Dolichandra unguis-cati : A Showy but Invasive Plant in Florida

Figure 1. Flowers and leaves of cat's-claw vine. The 3-pronged "claws" that replace the terminal leaflet in each compound leaf are visible at the lower right.Cat’s-claw vine is a neotropical, climbing perennial that produces large and showy yellow flowers in the springtime. It is valued as an ornamental, particularly in dry areas, because it needs little water or care and can climb almost anything, covering fences and other structures with an attractive carpet of leaves and flowers. Unfortunately, the aggressive nature of the vine has made it a major weed in China, Australia, South Africa, and parts of the southeastern United States. This 6-page fact sheet provides guidance on identification, control, and similar native vines for home landscapes. was written by Niels Proctor and Jason Smith, and published by the UF Department of School of Forest Resources and Conservation, October 2014.

Mosaic Disease of St. Augustinegrass caused by Sugarcane Mosaic Virus

Figure 1.  Mosaic symptoms on leaf blades of St. Augustinegrass infected with Sugarcane Mosaic Virus Mosaic disease of St. Augustinegrass was first reported in the 1960s in sugarcane producing areas of Palm Beach County, Florida. In the 10 years prior to 2013, less than 5 samples with mild symptoms were brought to the attention of the extension turfgrass pathologist. But in September 2013, an outbreak of the disease occurred in Pinellas County. Leaf symptoms included mosaic, but turned necrotic and the severe dieback that completely killed some infected lawns. In September 2014, lawns infected in 2013 and new lawns started dying in both Pinellas and Palm Beach Counties. Despite the similarity of symptoms to another St. Augustinegrass decline (SAD), as of November 2014, all samples have tested negative for SAD, and positive for presence of Sugarcane Mosaic Virus.

Weed Management in Rice

Figure 2. Flooded rice field in the EAA.Successful weed control is essential for economical rice production in the Everglades Agricultural Area. Weeds reduce rice yields by competing for moisture, nutrients, and light during the growing season. Weed infestations can also interfere with combine operation at harvest and can significantly increase harvesting and drying costs. Weed seed contamination of rice grain lowers grain quality and may lower the cash value of the crop. As with any biological system, an effective weed management program must consider many factors that vary from crop to crop and year to year. The most important of these factors include planting date, climatic conditions, seedbed preparation, seed quality, stand establishment, and water management.
