University of Florida Potato Variety Spotlight: 'Elkton'

Figure 1. Typical tuber set and internal flesh color of 'Elkton' 'Elkton' is a white-flesh potato variety suitable for chipping directly from the field. 'Elkton' was selected from the USDA-ARS breeding program in Beltsville, Maryland, by Dr. Haynes in 1997. In 2003, seed of 'Elkton' was made available for field evaluation under Florida growing conditions. In 19 trials conducted between 2003 and 2012, 'Elkton' yielded 111% in comparison with 'Atlantic'. In these trials, 'Elkton' demonstrated resistance to internal heat necrosis and hollow heart, which are common tuber physiological disorders under high-temperature growing conditions. This 3-page fact sheet was written by Lincoln Zotarelli, Douglas Gergela, Kathleen Haynes, and Dana Fourman, and published by the UF Department of Horticultural Sciences, April 2014.

Maslow's Hierarchy of Needs and Its Relation to Learning and Achievement

Figure 1. Maslow's Hierarchy of NeedsLearners in courses or training can be preoccupied. They worry about other courses, their home life, friends, extracurricular activities, physiological needs like food and sleep, and the list goes on. When learners are preoccupied with these concerns, learning and achievement are regularly put on the back burner. So how do we get our learners to focus on learning? Instructors can help learners satisfy needs, so the focus can be on content, learning, and achievement. This 3-page fact sheet was written by Sarah E. Burleson and Andrew C. Thoron, and published by the UF Department of Agricultural Education and Communication, April 2014.

Using Social Norms to Increase Behavior Change in Sustainable Landscaping

Figure 1. A graphic representation of the social marketing approach as applied to Extension programming. Adapted from McKenzie-Mohr, 2011.When Extension agents work to encourage behavioral changes in their community through educational programming, they may already be using some elements of social marketing. Extension educators can use an understanding of their clients’ reservations and inclinations toward a behavior, or their benefits and barriers, to develop strategies that encourage behavior change. Common strategies include prompts and reminders, incentives, and changing social norms. These strategies may be piloted on a small scale, modified if necessary, and then implemented on a large scale and further evaluated. This publication’s purpose is to describe the use of social norms as a social marketing strategy and make recommendations for applying social norms as a tool in Extension programming. This 5-page fact sheet was written by Laura Sanagorski and Paul Monaghan , and published by the UF Department of Agricultural Education and Communication, February 2014.

Livistona chinensis: Chinese Fan Palm

Figure 1. Chinese fan palm showing full round canopy of green leaves and retention of dead leaves below.The Chinese fan palm is relatively slow growing, typically reaching about 30 feet in height. Its fan-shaped, costapalmate leaves can be 3 to 4 feet across and up to 6 feet long. Petioles of juvenile palms are spiny, but have few or no spines in adult palms. Because of its gracefully drooping leaf segment tips, this species is sometimes called the “fountain palm”. Young specimens are slow to form a trunk, which has led to the unfortunate practice of planting these palms close together as a ground cover. Eventually, most of those closely planted palms will have to be removed to accommodate their 10 to 12 foot spread. This 5-page fact sheet was written by Timothy K. Broschat, and published by the UF Department of Environmental Horticulture, April 2014.

Minimizing Honey Bee Exposure to Pesticides

Figure 1. The western honey bee, Apis mellifera, collecting nectar from a flower.Protecting honey bees and other pollinators from pesticide impacts is important to the sustainability of agriculture. Consequently, pesticide applicators must determine if there is a clear hazard to managed or wild populations of bees. Potential exposure of bees to pesticides can vary greatly depending on the type of pesticide, formulation, application method, label restrictions, and other factors. The goal in using a pesticide is to achieve maximum benefit (success) with minimum negative impact, and these factors should always be considered in pesticide selection. This publication is written (1) to help assure the sustainability of both bees and agriculture by informing beekeepers, pesticide users, and the general public about the often complex relationship between pollinators (specifically bees) and pesticides, (2) to offer guidance for improved communication between beekeepers and pesticide users, (3) to offer pollinator risk-reducing strategies for growers and other applicators when using pesticides, and (4) to provide clarity in laws, labeling, and associated definitions.
