| 'Florida Beauty' Strawberry
‘Florida Beauty’ is a new strawberry cultivar released by the University of Florida and commercialized in 2017. This 4-page document describes the characteristics, performance, growth, and management of this cultivar. Written by Vance M. Whitaker, Natalia A. Peres, and Shinsuke Agehara and published by the UF/IFAS Horticultural Sciences Department, November 2017. |
| Foliar or Bud Nematodes in Florida Strawberries
Foliar or bud nematodes are little-known nematodes that caused “crimp disease” in Florida strawberries in the early 1900s. Recently, these foliar nematodes have been observed again in the state, and seem to have come in with transplants from outside Florida. Foliar/bud nematodes can devastate a crop of strawberries. Plants become stunted with curled up leaves, and produce few or no flowers or fruits. This 7-page fact sheet written by J. Desaeger and J. Noling and published by the UF/IFAS Department of Entomology and Nematology provides much-needed information on these little-understood pests, summarizing the different types of foliar nematodes, their biology, life cycle, damage symptoms, survival strategies, dissemination, and management options. |
| Food Safety on the Farm: Good Agricultural Practices and Good Handling Practices-Field Sanitation

| UF/IFAS Standardized Nutrient Recommendations for Vegetable Crop Production in Florida
Soil testing is a scientific tool for effective nutrient management that provides an estimate or an index of the available nutrient-supplying capacity of the soil. This 9-page publication presents the fertilization recommendations for vegetable crops based on soil tests performed by the IFAS Extension Soil Testing Laboratory (ESTL).

| Satsuma Mandarin Budget and Profitability Analysis for North Florida
This 16-page analysis written by Kevin R. Athearn, Peter C. Andersen, Bent V. Brodbeck, Lei Lani L. Davis, Clay Olson, Daniel K. Fenneman, Matthew Lollar, Derek Farnsworth, and Michael Perez and published by the UF/IFAS Food and Resource Economics Department provides research-based information and a description of satsuma mandarin markets, production costs, and potential returns for citrus growers who are considering establishing a satsuma grove in north Florida. Its purpose is to serve as a reference and model for growers to create their own enterprise budgets and make financial projections. An enterprise budget estimates revenues, costs, and net returns for a particular crop or farm enterprise to help growers assess the economic viability and risk of an enterprise, compare enterprises, and evaluate production or marketing changes. The budget and financial analysis may assist prospective and current satsuma growers, agricultural consultants, and lenders with planning and decision making. |

| Micronutrients Considerations for Warm-Season Forage Grass Systems in Florida
Warm-season grasses are vital to livestock production systems and dominate ground cover in tropical and subtropical areas. The objective of this 7-page publication is to provide basic information about the role of micronutrients in warm-season grass production systems in Florida. Written by Jane C. Griffin, Joao Vendramini, Diane Rowland, and Maria L. Silveira and published by the UF/IFAS Agronomy Department, November 2017. |
| Nutrition at Early Stages of Life Determines the Future Growth and Reproductive Performance of Dairy Calves
For a calf, nutrition during the first few months of its life may permanently change the way organs develop and then have long-term consequences. The concept that metabolic imprinting may permanently affect animal development has substantial economic implications for agriculture. This 6-page fact sheet summarizes some of the research conducted in calf nutrition and its impact on the growth and reproductive performance of dairy calves. Written by Philipe Moriel and Luiz Ferraretto, and published by the UF/IFAS Department of Animal Sciences, December 2017. |

| Biscogniauxia (Hypoxylon) Canker or Dieback in Trees
Biscogniauxia canker or dieback is a common contributor to poor health and decay in a wide range of tree species growing in many different habitats, such as forests, parks, green spaces, and urban areas, in Florida. This disease is caused by several species of fungi in the genus Biscogniauxia (formerly Hypoxylon). These pathogens do not typically harm healthy and vigorous trees, but once they infect trees under stress from drought, root disease, soil compaction, construction damage or other causes, they can quickly colonize the tree. Once a tree is infected and fruiting structures of the fungus are evident, the tree is not likely to survive, especially if the infection is in the trunk. This 3-page fact sheet written by Claudia Paez and Jason Smith and published by the UF/IFAS School of Forest Resources and Conservation explains the pathogen’s biology and lists signs and symptoms as well as control measures and ways to keep trees healthy to resist infection. |
| Florida Trees Store Carbon in Forests and Wood Products
Trees store carbon as they grow and produce wood. Carbon, and carbon storage in particular, have become important topics as policymakers, scientists, and industry leaders consider how to address the increasing amount of CO2 in our atmosphere. Because it changes the composition of the atmosphere, CO2 is a leading contributor to climate change. This 4-page fact sheet written by Adam Maggard, Leslie Boby, and Martha Monroe and published by the UF/IFAS School of Forest Resources and Conservation explains how storing carbon in living trees and in long-lasting wood products such as lumber and furniture can reduce atmospheric CO2. Florida’s forest and wood-product industries are worth billions of dollars. Clean water, wildlife, and other benefits add to the value and importance of these forests. |
| Impervious Surface Thresholds and the Pace to Plant Technique for Planting Urban Red Maple Trees
A foundation of integrated pest management (IPM) in urban landscapes is to put the right plant in the right place. This preventive tactic can reduce plant stress, pest infestations, and subsequent pesticide applications. Many urban tree species have more insect and mite pests in urban landscapes than in surrounding natural areas. This is due in part to stress created by impervious surfaces like roads and sidewalks that make the air hot and the soil dry. For red maples (Acer rubrum), more impervious surface area adds stress and worsens tree condition. This 4-page publication written by Adam G. Dale, Steven D. Frank, Elsa Youngsteadt, Barbara Fair, Julieta Sherk, and Michael Just and published by the UF/IFAS Department of Entomology and Nematology focuses on selecting red maple planting sites that will help reduce tree stress and scale insect pests by maximizing surfaces permeable to water. |

The Worker Protection Standard (WPS) Act for Agricultural Pesticides was established by the US Environmental Protection Agency in 1992 and has undergone several revisions since. Recent revised provisions became effective in January 2017. This document will address the additional requirements for agricultural employers of workers under the revised WPS. Written by Frederick M. Fishel and published by the UF/IFAS Agronomy Department, December 2017. |

This 5-page document addresses consumers’ perceptions of Florida peaches, purchasing motivations and barriers, preferred packaging options and opportunities, purchasing locations, and knowledge of peach health benefits. Written by Joy Rumble, Kara Harders, and Kathryn Stofer and published by the UF/IFAS Department of Agricultural Education and Communication, December 2017. |
| Nursery & Greenhouse |
| Caladium Cultivars 'Cosmic Delight', 'Fiesta', and 'Hearts Desire'
Caladiums are commonly grown in containers, hanging baskets, or planted directly in the landscape as accent and border plants. New caladium cultivar introductions are important to the Florida caladium industry, the greenhouse/nursery industries, and commercial landscape maintenance companies. The UF/IFAS Gulf Coast Research and Education Center released three new caladium cultivars, ‘Cosmic Delight’, ‘Fiesta’, and ‘Hearts Desire’, in 2015. This 7-page document describes the characteristics, production potential, and performance of these cultivars. Written by Zhanao Deng and published by the UF/IFAS Environmental Horticulture Department, December 2017. |
| Hurricane Preparation List for the Container Nursery
Busy professionals don’t often have time to consider the impact a hurricane can have on their nursery until one is on the way. This 2-page fact sheet provides a list of items and tasks to complete prior to a hurricane’s arrival to minimize damage to the nursery. Written by Tom Yeager and published by the UF/IFAS Environmental Horticulture Department, December 2017. |
