El Mandato del Dispositivo de Registro Electrónico (ELD por sus siglas en ingles), se convirtió en mandato para vehículos motorizados comerciales (CMV) el 18 de diciembre del 2017. El 18 de junio del 2018, después de 90 días de extensión, el mandato también se aplicó a transportistas de productos. El propósito principal detrás del ELD fue asegurar el cumplimiento con los requerimientos de Horas de Servicio (HOS) por autotransporte y sus conductores. Este artículo se enfoca en el movimiento interestatal de propiedades (productos), and sus objetivos son: 1) revisar las reglas HOS; 2) clarificar las excepciones agrícolas a las reglas HOS; y 3) ofrecer una discusión preliminar a cómo los ELD podrían afectar a los productores del sur de Florida.

Tetraploid Induction and Establishment of Breeding Stocks for All-Triploid Seed Production
Triploid-tetraploid breeding technology has been applied to commercial oyster aquaculture worldwide. Triploid oysters are becoming the preferred aquaculture product because of their fast growth, better meat quality, and year-round harvest. Tetraploids are essential for triploid oyster aquaculture because commercial production of all-triploid seed depends on the availability of tetraploids for reproductive materials. This 8-page fact sheet written by Huiping Yang, Ximing Guo, and John Scarpa and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences, conveys basic knowledge about tetraploid induction and breeding to commercial shellfish culturists and the general public.

Biology and Management of Pusley (Richardia L.) in Tomato, Pepper, Cucurbit, and Strawberry Production
Four species of pusley (Richardia L.) are widespread and common weeds in Florida vegetable and strawberry production. We refer to the native plant Richardia scabra L. as Florida pusley. This discrimination is necessary because these species are often referred to collectively as Florida pusley due to overlapping distributions, similar growth habits and leaf morphologies, and difficulty identifying without the presence of fruit. This new 6-page publication of the UF/IFAS Horticultural Sciences Department describes the different pusley species and provides management options for strawberry, pepper, cucurbits, and tomato. Written by Shaun M. Sharpe, Nathan S. Boyd, Chris Marble, and Shawn Steed.

Nitrogen Contributions from Peanut Residues to Subsequent Crops
There is not enough evidence to support current peanut N credit recommendations in the Southeast. Nitrogen is released rapidly from peanut residues, and it moves quickly through light-textured soils found in this region. Only a relatively small amount of N from peanut residues is available when subsequent crops need it. This new 5-page document discusses peanut nitrogen credits, nitrogen release from peanut residues, crop performance following peanut, tillage and nitrogen release, and peanut residue distribution and nitrogen release. Written by Arun Jani and Michael J. Mulvaney, and published by the UF/IFAS Agronomy Department, April 2019.

Butterfly Pea (Clitoria ternatea) Flower Extract (BPFE) and Its Use as a pH-Dependent Natural Colorant
Butterfly pea (Clitoria ternatea), a twining vine native to Southeast Asia, produces deep blue to purple flowers that bloom nearly year-round in ideal conditions. When extracted in a liquid, the addition of a mild acid such as lemon or lime juice turns the naturally deep blue to purple color into a much lighter pink or purple color, giving the extract its color-changing ability. This new 5-page publication of the UF/IFAS Environmental Horticulture Department outlines the use of butterfly pea flower extract (BPFE) as a pH-dependent natural colorant, including an explanation of the science behind the color change, detailed parameters for flower extraction, instructions for storage and processing of the extract as well as a discussion of some of the other benefits of using BPFE.

La Granada en Florida: Una fruta de arbol para Florida?
El potencial económico en la producción comercial para el cultivo de granadas en Florida es actualmente desconocido en este momento. La investigación científica continúa sobre la posibilidad de encontrar variedades de granadas que puedan crecer en Florida. Las condiciones ambientales, con una alta temporada húmeda en la Florida, y un clima caluroso, son factores que son favorables para las enfermedades en las granadas y eso reduce la calidad de esta fruta, especialmente para las variedades de temporada tardía como la variedad ‘Wonderful’. ‘Wonderful’ es el principal cultivar comercial que se originó en la Florida. Para reducir las enfermedades y evitar la competencia de comercialización con las granadas de California, la investigación para la producción de granadas en la Florida debe centrarse en buscar variedades de temporada temprana que puedan cosecharse en julio y agosto. This six-page document is the Spanish translation of HS44, The Pomegranate.

Food Safety on the Farm: Good Agricultural Practices and Good Handling Practices: an Overview
Good Agricultural Practices (GAPs) and Good Handling Practices (GHPs) encompass the general procedures that growers, packers and processors of fresh fruits and vegetables should follow to ensure the food safety of their product. GAPs usually deal with preharvest practices (i.e., in the field), while GHPs cover postharvest practices, including packing and shipping. We will use the term GAPs in this fact sheet to generally cover pre- and postharvest practices associated with the safe handling of produce, both fresh and minimally processed. This five-page introduction to the Food Safety on the Farm series provides an overview of GAPs and GHPs, summarizing major principles and recommendations of later documents in the series. Written by Jaysankar De, Christopher R. Pabst, Jessica Lepper, Renée Goodrich Schneider, and Keith R. Schneider and published by the UF/IFAS Food Science and Human Nutrition Department.
