April’s offerings in the Agriculture program area include parasite control in goats and poultry, using sulfur as a soil amendment, citrus nutrition, and fertilizer management for tomato, pepper, and potato crops.
Goat Parasite Control: General Guidelines
Gastrointestinal (GI) parasitism is the leading cause of death and decreased production in goats. At least 48% of farms in the southeast have parasites that are resistant to all classes of dewormers. While there is no one-size-fits-all recommendation for parasite control, the information in this fact sheet is provided for on-farm use. Contact your veterinarian for specific recommendations. Information was provided by Dr. Sarah Reuss of the UF Large Animal Medicine Service. This 2-page fact sheet was written by Sarah Reuss, and published by the UF Department of Animal Sciences, February 2014.
Intestinal and Tracheal Parasites of Poultry
A parasite is defined as an animal or plant that derives sustenance and/or protection by living in or on another animal or plant called the host. Intestinal and tracheal parasites of poultry are commonly referred to as “worms,” although this term is technically not correct. These parasites can cause chickens in a flock to appear unthrifty, which often leads to secondary complications. In some cases, the parasites can cause mortality in the flock. Frequent inspection of the flock for signs of illness is the best management tool for identifying when these parasites are a problem. This 3-page fact sheet was written by Gary D. Butcher and Michael A. Davis, and published by the UF Department of Animal Sciences, April 2014.
Effect of Reduced Soil pH with Sulfur on Available Soil Phosphorus in High pH Sandy Soils of South Florida
This 3-page fact sheet addresses the effect of moderating soil pH by using sulfur amendments in high pH soils and discusses their relationship to both nutrition and fertilizer management. Written by Kelly T. Morgan and Kamal Mahmoud, and published by the UF Department of Soil and Water Science, December 2013.
Iron (Fe) and Copper (Cu) for Citrus Trees
Since mineral nutrition is a major factor in maximizing yield of high-quality fruit, understanding the functions of mineral elements, diagnosing nutrient deficiencies, and providing needed fertilizers are essential. This publication describes and discusses iron (Fe) and copper (Cu) deficiencies, functions, and recommended practices to alleviate nutritional problems. This 7-page fact sheet was written by Mongi Zekri and Tom Obreza, and published by the UF Department of Soil and Water Science, March 2014.
Manganese (Mn) and Zinc (Zn) for Citrus Trees
Since mineral nutrition is a major factor in maximizing yield of high-quality fruit, understanding the functions of mineral elements, diagnosing nutrient deficiencies, and providing needed fertilizers are essential. This publication describes and discusses manganese (Mn) and zinc (Zn) deficiencies, functions, and recommended practices to alleviate nutritional problems. This 5-page fact sheet was written by Mongi Zekri and Tom Obreza , and published by the UF Department of Soil and Water Science, March 2014.
Effect of Fertilizer Phosphorus Rate of Tomato and Green Bean Yield and Growth in High pH Sandy Soils of South Florida
This 4-page fact sheet addresses the effect of phosphorus rate on tomato and green bean yield and growth in high pH soils and discusses their relationship to both nutrition and fertilizer management. Written by Kelly T. Morgan and Kamal Mahmoud, and published by the UF Department of Soil and Water Science, December 2013.
How to Calculate a Partial Nitrogen Mass Budget for Potato
This 6-page fact sheet provides information on the importance of nitrogen budgets for potato cultivation and discusses the steps in preparing the budget. It allows growers to understand the inputs, cycling, and exports of nutrients within and away from the farm, develop a nutrient budget, and analyze best management practices (BMPs) for their farm. The results will be increased N fertilizer use efficiency, increased environmental protection, and reduced economic losses associated with potato cultivation. This document will also aid county agents, environmental management advisors, and government agency staff members who help farmers improve and implement nutrient BMPs to protect water quality. Written by Rishi Prasad and George Hochmuth, and published by the UF Department of Soil and Water Science, December 2013.
Integrated Pest Management
Minimizing Honey Bee Exposure to Pesticides
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. This 14-page fact sheet was written by J. D. Ellis, J. Klopchin, E. Buss, F. M. Fishel, W. H. Kern, C. Mannion, E. McAvoy, L. S. Osborne, M. Rogers, M. Sanford, H. Smith, P. Stansly, L. Stelinski, and S. Webb, and published by the UF Department of Entomology and Nematology, March 2014.
Como hacer una trampa interceptora de chinches de cama de articulos comunes del hogar.
Las chinches de cama se han convertido en un problema de plagas cada vez más común en los Estados Unidos. Se han encontrado en muchos lugares diferentes en donde vive la gente, desde escuelas y restaurantes a consultorios médicos y salas de cine, pero las peores infestaciones son por lo general en lugares donde vive la gente, descansan y duermen como en casas, pisos, apartamentos, hoteles y refugios para desamparados. Las chinches de cama son más comunes en lugares como alrededor de piezas de mobiliario en donde la gente se sienta o acuesta- camas, sillas y sofás. Para descubrir si las chiches están presentes en una habitación o un mueble, el dispositivo llamado trampa interceptora de chinches puede ser útil. Las trampas interceptoras atrapan y recogen las chinches de cama cuando tratan de viajar entre sus huéspedes humanos y sus escondites. Las trampas interceptoras de chinches de cama son fácilmente hechas de artículos del hogar y recipientes de plástico desechables. This 4-page fact sheet was written by Benjamin A. Hottel, Rebecca W. Baldwin, Roberto M. Pereira, and Philip G. Koehler, and published by the UF Department of Entomology and Nematology, February 2014.
Aster leafminer moth Leucospilapteryx venustella (Clemens) (Insecta: Lepidoptera: Gracillariidae)
Leucospilapteryx venustella (Clemens) (Lepidoptera: Gracillariidae) is a small, mostly light brown moth that during its larval stages creates mines in the leaves of plants in the family Asteraceae. Feeding damage by the early instars is characterized by serpentine mines that are expanded by later instars to form tentiform or blotch mines. This 4-page fact sheet was written by Rodrigo Diaz, Esteban Tapia, Veronica Manrique, William Overholt, and Donald Davis, and published by the UF Department of Entomology and Nematology, February 2014.
