Sugarcane Ring Spot
Ring spot, caused by the fungus Leptosphariea sacchari, is a disease of sugarcane that has been known to occur in Florida for over 80 years. Ring spot usually affects only the older leaves, and therefore is considered a minor disease. However, correctly identifying the disease in the field can help to reduce unnecessary chemical sprays. This two-page fact sheet outlines the symptoms and spread of the disease, as well as how to prevent and control Sugarcane Ring Spot. Written by P. Rott, J.C. Comstock, H.S. Sandhu, and R.N. Raid, and published by the Plant Pathology Department.

Postharvest Storage, Packaging and Handling of Specialty Crops: A Guide for Florida Small Farm Producers
Every year farmers must harvest their crops. This process marks the end of the growing season and carries social significance in communities, but it also creates challenges for producers trying to deliver fresh, high-quality produce to market. Good postharvest practices establish appropriate cold chains that maintain the correct temperatures, humidity, and respiration rates while also ensuring the safety, sanitation,and quality of the fruits. These postharvest practices differ, depending on the size and economic situation of an operation. This eighteen-page fact sheet provides postharvest storage, packaging, and handling recommendations for small farm specialty crop producers. Written by Jonathan Adam Watson, Danielle Treadwell, Steven A. Sargent, Jeffrey K. Brecht, and William Pelletier, and published by the Horticultural Sciences Department.

Weed Control for Ornamentals inside Greenhouses and Other Enclosed Structures
Maintaining a weed-free greenhouse is important for producing healthy and marketable crops. Weeds will compete with crops for water, light, and nutrients. Weeds can find favorable conditions for growth in gravel and along edges, tears, and worn areas of ground cloth. It is important to frequently scout for weeds. This five-page fact sheet describes both chemical methods of controlling weeds, but also non-chemical methods, such as sanitation and prevention, hand weeding, and cultural control practices. Written by Chris Marble and Jeremy Pickens, and published by the Environmental Horticulture Department.

El Zika, un Virus Transmitido por Mosquitos
Zika es un virus transmitido por mosquitos que se ha esparcido recientemente en regiones tropicales y ha causado epidemias, especialmente durante los últimos 8 o 9 años. En su ámbito nativo en África Occidental y Uganda, el virus se mantiene en los bosques, circulando entre mosquitos que viven en huecos de árboles y primates arbóreos; las infecciones de humanos se consideran incidentales y de poca importancia médica. Una cepa del virus que se implicó en brotes en Polinesia Francesa emergió en el Norte de Brasil en el 2015 y causó gran consternación debido a la alta incidencia de microcefalia en bebes nacidos de madres que fueron infectadas con el virus durante la gestación. Transmisión local, principalmente por el mosquito de la fiebre amarilla Aedes aegypti, ha sido documentada en la mayoría de los países tropicales de las Américas, pero aún no se ha detectado en Los Estados Unidos Continentales. Los síntomas de la infección incluyen, salpullido, dolor de cabeza, fiebre, dolor muscular y en las coyunturas, conjuntivitis, y malestar general.
This 7-page fact sheet written by J. R. Rey, L. P. Lounibos, B. W. Alto, N. D. Burkett-Cadena, C. C. Lord, C. T. Smartt, and C. R. Connelly and published by the Department of Entomology and Nematology is the Spanish language version of Zika, a Mosquito-Transmitted Virus and describes the Zika microbe, its mosquito hosts, and the disease it causes. A history of the virus and its migration are included, along with some details about the virus in the state of Florida and preventative measures people can take to avoid infection. The best way to avoid contracting Zika (and other mosquito-borne diseases) is not to get bitten in the first place. Take precautions to avoid mosquito bites.

Ejemplo Ilustrativo de los Costos y Rentabilidad de la Produccion de Aguacates en el Estado de la Florida
Los cultivos de árboles frutales son de gran importancia económica en la agricultura del estado de la Florida; en este segmento, la industria del aguacate ocupa el segundo reglón económico tras los cítricos. Aproximadamente el 80 por ciento de la cosecha se vende fuera del estado; por lo tanto, la industria aporta una cantidad considerable de “dólares nuevos” al estado, lo que resulta en un impacto económico total de cerca de $100 millones por año. Este artículo proporciona una estimación de los costos y rendimientos asociados a la producción de aguacate en el Condado de Miami-Dade y un breve análisis de la rentabilidad de la industria.

Practices to Minimize Flooding Damage to Commercial Vegetable Production
Flooding is a major risk for commercial vegetable production in south Florida, especially in the south Dade County area. Flooding causes oxygen deficiency, or hypoxic stress, causing the plants to produce less energy. This shortage in energy prevents the absorption of nutrients like nitrogen, phosphorous, and potassium. This four-page fact sheet discusses several different management practices for overcoming flood damage, including the use of nitrogen and potassium fertilizers, oxygen fertilizers, growth regulators, and fungicides. Written by Goudong Liu, Yuncong Li, and Xiangju Fu, and published by the Soil and Water Science Department.

An Overview of the US and Mexico Strawberry Industries
The statistics of the Food and Agriculture Organization of the United Nations indicate that world production of strawberries has exceeded 4 million metric tons since 2007. With a total production of 1.4 million tons (3 billion pounds) in 2012, the United States is the largest producer among countries where statistical data are available, accounting for about 30% of the world supply. Production in Mexico increased from 140 thousand tons to 360 thousand tons, making Mexico the second-largest strawberry producer in the world. This four-page fact sheet written by Feng Wu, Zhengfei Guan, and Alicia Whidden and published by the UF Food and Resource Economics Department provides an overview of the US and Mexican strawberry industries, paying special attention to the trade relations between the two countries.

Spironucleus Infestations (Spironucleosis) in Freshwater Aquarium Fish
A group of species of single-celled parasites called Spironucleus cause disease in aquacultured and captive fish. Found in cold, temperate, and tropical climates, Spironucleus species can infect a variety of freshwater and marine ornamental and food fish, as well as crustaceans and shellfish.
Five species of Spironucleus are currently recognized: S. salmonicida, S. barkhaus, and S. torosa can infest marine organisms, while S. salmonis and S. vortens can infest freshwater ornamental fish. This four-page fact sheet written by Ruth Francis-Floyd and Roy P. E. Yanong and published by the Department of Large Animal Clinical Sciences focuses on S. vortens and its effects on ornamental cichlids, explaining which cichlids are susceptible, how to identify S. vortens , and how to confirm, manage, and prevent S. vortens infestations.
