Pollination Best Practices in Southern Highbush Blueberry in Florida

Apis mellifera, the European honey bee.

Southern highbush blueberry is the primary blueberry species grown in Florida. It is dependent upon pollinating insects for adequate pollination and fruit. Some Florida growers have reported cases of low fruit set in recent years, in particular on the cultivars Meadowlark and Emerald, which may have been due in part to poor pollination. This 5-page fact sheet written by Rachel E. Mallinger and Douglas A. Phillips and published by the UF/IFAS Department of Entomology and Nematology will discuss blueberry pollinators, some causes of poor pollination, and current best practices to reduce the possibility of poor pollination of southern highbush blueberry.

La Ley de Modernización de la Seguridad Alimentaria (FSMA) se convirtió en ley en enero de 2011 y se considera la reforma más amplia de las normas de seguridad alimentaria en 70 años. Primero, se establecieron las regulaciones sobre alimentos para el consumo humano luego con la contribución de la industria, la academia, y los consumidores y otras agencias, se modificaron para adaptarse mejor a la producción de alimentos para animales. En Florida, estas nuevas regulaciones se aplican a las instalaciones que fabrican, procesan, empacan o almacenan alimentos o ingredientes para animales. El objetivo principal de estas regulaciones es garantizar alimentos seguros para los animales, las personas que manejan el alimento y las personas que consumen productos derivados de animales. This 4-page document is the Spanish version of The Food Safety Modernization Act (FSMA) Preventive Controls for Animal Food. Written by Francisco Rivera, Chad Carr, and Jason M. Scheffler, and published by the UF/IFAS Department of Animal Sciences, February 2019.

Potassium Fertilizer Recommendations for Sugarcane on Florida Organic Soils

Potassium is a primary plant nutrient that is required in large amounts by sugarcane. About 74% of the 400,000 acres of Florida sugarcane is grown on organic soils in the Everglades Agricultural Area. Potassium is not a component of organic matter and virgin Histosols contain very low concentrations of K, so release of K through mineralization of organic matter in these soils is not an adequate K source for plant growth. This 7-page document presents revised potassium fertilizer recommendations for sugarcane grown on Florida organic soils along with supporting information. Written by J. Mabry McCray, and published by the UF/IFAS Agronomy Department, February 2019.

Pastures and Forage Crops for Horses

Horse grazing bermudagrass.

Florida's unique climatic characteristics allow for forage production most of the year with a large variety of possible forage choices. Independent of the size of the operation and number of horses, good forage planning can help reduce feeding costs, environmental impacts, and nutritional disorders caused by high-concentrate feeding. With the exception of high-performance animals, horses can meet most of their nutritional needs from pasture. However, achieving this requires careful planning and implementation of a forage production and utilization program. This 9-page document discusses intake and nutrient requirements, pasture planning, forage species, and pasture management. Written by M. Wallau, E. L. Johnson, J. Vendramini, C. Wickens, and C. Bainum, and published by the UF/IFAS Agronomy Department, revised January 2019.

The southern pine beetle, Dendroctonus frontalis Zimmermann, is the most destructive insect pest of pine in the southern United States. This 8-page fact sheet written by Demian F. Gomez and Jiri Hulcr and published by the UF/IFAS Department of Entomology and Nematology describes the beetle and includes advice on how to monitor for them and strategies for their prevention and control.

Geosmithia Species in Florida: Common Fungal Symbionts of Wood-Boring Bark Beetles

Geosmithia are fungi associated with wood-boring bark beetles. Most Geosmithia species do no harm to host trees, but the canker-causing Geosmithia morbida and its beetle vector, the walnut twig beetle, cause the disease complex known as thousand cankers disease on walnut trees. Continuous surveys in Florida have found neither Geosmithia morbida nor its beetle vector in the state, but many native Geosmithia species have been recovered. These native species look similar to the pathogenic fungus but are harmless to their plant hosts. This 4-page fact sheet written by Yin-Tse Huang and Jiri Hulcr and published by the UF/IFAS School of Forest Resources and Conservation provides basic guidelines to sample Geosmithia species in the field and information for distinguishing the plant pathogenic Geosmithia morbida from other Geosmithia species.
