Plagas y Hongos Identificados en Olivos (Olea europea) en Florida

Figure 1. Leaffooted bug, Leptoglossus phyllopus, on an olive tree in Marion County, Florida.La producción de olivo o aceitunas (Olea europea) en Florida ha aumentado en los últimos años. La disponibilidad de árboles en los viveros de plantas ha aumentado y muchos residentes los compran para plantarlos en su patio. Afortunadamente, los olivos son una especie relativamente resistente a muchas plagas, pero en ocasiones surgen invasores que pueden causar daños significativos. Algunos patógenos también pueden infectar los olivos y causar enfermedades, reducir los rendimientos o arruinar la apariencia estética de los árboles. Siguiendo las prácticas de cultivo apropiadas para olivos podemos reducir las probabilidades de perder árboles por plagas y enfermedades. Una encuesta realizada con productores de aceitunas en Florida durante el año 2014 identificó las plagas y enfermedades descritas en este documento.

Florida Strawberry Producers' Experiences with Anthracose and Botrytis Fruit Rot, and Producers' Use of the Strawberry Advisory System

Figure 1. Anthracnose lesions on a ripe fruit (Mertely and Peres 2012)Florida’s producers use fungicides to manage anthracnose and botrytis fruit rot diseases, which find favorable growth conditions in Florida’s climate and can reduce strawberry yields and profits. The Strawberry Advisory System (SAS) uses information about weather conditions and user-entered information about past fungicide applications to evaluate the potential spread of these diseases in strawberry fields. If the risk of disease spread is low, no fungicide application is recommended, allowing producers to save on fungicide application costs. In this study, we summarize the results of a 2012/2013 survey of strawberry producers, and focus on the questions, How significant is the impact of anthracnose and botrytis on Florida strawberry producers’ yields? What are the typical fungicide application frequencies used by the producers? What percent of strawberry producers use SAS? and Are there any effects of SAS subscription on producers’ fungicide application?

Establishment Cost of Avocados in South Florida

avocado orchardA major concern for the future of the Florida avocado industry is laurel wilt disease (LW), which is caused by fungus transmitted by the ambrosia beetle. Cost-effective management of LW relies heavily on the early detection and destruction of affected trees (sanitation). While not an official recommendation, some suggest that since the beetles are less attracted to younger trees, growers might consider leaving the young orchards in production while replanting only older and less productive orchards. Since the long-term survival of the Florida avocado industry may ultimately depend on a combination of eradication, prophylactic treatment, and replanting the trees, the purpose of this article is to provide an updated guidance on the costs of establishing an avocado orchard. Information presented in this study is based on interviews with growers, orchard service companies, extension agents, and other industry personnel. It is intended as a guide only to make production decisions, prepare budgets, and investigate insurance options. A follow-up document to this one will focus on the cost and return of maintaining an orchard after it has been established. This 9-page fact sheet was written by Braulia De Oleo, Edward A. Evans, and Jonathan H. Crane, and published by the UF Department of Food and Resource Economics, October 2014.

Managing Against the Development of Herbicide-Resistant Weeds: Sugarcane

Figure 1. Sugarcane rows in the Everglades Agricultural Area (EAA) following herbicide application and cultivation.Profitable sugarcane production in Florida requires effective weed management. Herbicides provide an efficient and cost-effective means of weed control, but excessive use of a single herbicide or group of herbicides with the same mechanism of action has resulted in the development of herbicide-resistant weeds. In crops such as sugarcane where a limited number of herbicides are registered, the loss of a single effective herbicide can be very costly. Thus, it is critical to manage herbicides in order to prevent or delay the development of herbicide-resistant weed populations. This 4-page fact sheet lists herbicides by group number, mechanism of action, chemical family, common name, and trade name. Written by D.C. Odero, B.A. Sellers, J.A. Ferrell, and G.E. MacDonald, and published by the UF Department of Agronomy, October 2014.

Converting from seepage irrigation to plasticulture for vegetable production: a case study and on-farm demonstration

Figure 6. Soil moisture sensors installed under plastic mulch in both inner and outer plant rows.Cabbage production in Florida has been dominated by the use of seepage or sub-irrigation, because it is inexpensive to maintain and simple to use, but it can require vast quantities of water to be pumped from the aquifer in low rainfall years. Plasticulture has been proposed as an alternative production method for cabbage production in Florida. An on-farm demonstration was setup on Greene’s Farms in Bunnell, FL to provide a platform for collaboration between researchers, growers and extension professionals. This 6-page fact sheet illustrates an innovative approach converting from seepage irrigation to plasticulture and points out some options and challenges for growers considering a plasticulture system.

Candidate Species for Marine Ornamental Aquaculture: Porkfish, Anisotremis virginicus

Figure 1. Adult porkfish.The porkfish is a member of the grunt family, which create a characteristic “grunting” sound by rubbing their pharyngeal teeth together during periods of agitation or courtship. Many species of grunts are popular in public aquariums because they?re abundantly available, and their schooling behavior and bright colors create interest in aquarium exhibits. Porkfish also have additional appeal to aquarists because they are “cleaner” fish during their juvenile phase, picking parasites from larger fish and other vertebrates. Scientists and aquarists have recently achieved a greater understanding of appropriate aquaculture protocols for grunts in general and porkfish in particular. These characteristics and advancements have led to porkfish being identified as a candidate species for commercial aquaculture.

Description of Enhanced-Efficiency Fertilizers for Use in Vegetable Production

Figure 1. Urea-formaldehyde slow-release fertilizer.In response to the Federal Clean Water Act of 1972 and the Florida Restoration Act of 1999, a series of best management practices (BMPs) was implemented to improve surface and ground water quality. BMPs are cultural practices that, when implemented as a plan, help reduce the environmental impact of production while maintaining yield and quality. One of these BMPs includes the use of controlled-release fertilizer, which is an enhanced-efficiency fertilizer. This publication describes the common enhanced-efficiency fertilizers and the factors affecting their use in Florida vegetable production.

The Impact of Fathers on Children's Well-Being

father talking to young son.American families have changed dramatically over the last century. Currently, about half the children in the United States will live apart from their fathers some time during their childhood because their parents have separated and the proportion of births to unmarried women has risen from 5 percent in 1960 to 41 percent in 2011. But a father who is absent from the household may not necessarily be absent from his child’s life. This 5-page fact sheet provides a brief summary of the history of fatherhood in America and discusses the importance of involved fathers, and how mothers, other family members, and adult role models can make a positive impact in a child’s life.

Emphasizing the Science, Technology, Engineering, and Math (STEM) in Agricultural Extension

Dr. Wendell Porter (far right) instructs 4H members participating in science and technology activities during the 2011 4H Congress.  UF/IFAS Photo by Tyler Jones.STEM is an acronym for science, technology, engineering, and math. In Extension, our purpose is to share the knowledge or products created through Ag-STEM research and design by universities and government agencies. Finding effective solutions to agricultural issues, especially in urban areas, increasingly involves working with clientele to solve problems jointly. Therefore, emphasizing the connections of STEM to agricultural problems through Ag-Extension programming can help our public audiences comprehend the problem-solving system underlying the content. The goal is to provide public audiences with self-confidence and skills in STEM, preparing them to be more engaged in the problem-solving process for the challenges ahead.

Measuring Community Resilience using Online Toolkits

A canal close to the beach in Naples, Florida.  When we return to the scene of recent disasters like New Orleans, we find that some communities and neighborhoods are able to recover faster than others, while some never completely recover. Community Resilience is defined as the ability for a community to bounce back from a disaster, adapt to changes, and become more sustainable. The resilience assessment and planning tools reviewed here range from simple, ready-to-print worksheets intended for use by average citizens to comprehensive planning exercises more appropriate for city planners, emergency service providers, and elected officials. Not all of the toolkits will apply to every community.

Tracking the Economic Benefits Generated by the Hard Clam Aquaculture Industry in Florida

handful of clams The hard clam industry is a true success story for commercial aquaculture in Florida. From a cottage industry borne of reductions in commercial wild clam harvests in the Indian River Lagoon during the late 1980s, hard clam aquaculture has now developed into an industry that is rivaled by no other aquaculture food product in Florida. Although successful by virtually any metric, the risks and uncertainty associated with commercial hard clam culture has led to the evaluation of programs that help mitigate risk, such as the former pilot Cultivated Clam Crop Insurance Program administered by USDA Risk Management Agency. All of this alludes to the economic importance of the hard clam culture industry which, through the cultivation process and sales of products, generates local income and taxes, creates jobs and businesses, and draws new money into the local economy, as cultured hard clams are sold to non-residents and buyers outside the region and state. This 6-page fact sheet provides an overview of a recent study by the University of Florida to provide an estimate of the impact of the hard clam industry to the Florida economy.
