Recomendaciones para el Control y Mitigación de la Marchitez del Laurel y sus Vectores, los Escarabajos Ambrosia, en Arboledas Comerciales de Aguacate en Florida

Jonathan H. Crane, Daniel Carrillo, Edward A. Evans, Romina Gazis, Bruce Schaffer, Fredy Ballen, y Jeff Wasielewski Traducido por Rubén Regalado. Revisado por Dr. Carlos F. Balerdi

El control del complejo agente patógeno ML - EA es difícil debido a la posibilidad de que ocurra una transmisión rápida por injertos de raíces, por nuevas infestaciones de ML debido al movimiento del EA, y a las dificultades y costos de las tácticas de control existentes. Las investigaciones en curso tienen como objetivo lograr un conocimiento más profundo de la biología del agente patógeno de la ML y el EA capaz de transmitirlo, de la epidemiología (dinámica de la dispersión de la enfermedad), y desarrollar métodos de control y tácticas de mitigación más eficaces. Las recomendaciones de control serán revisadas tan pronto se conozca información adicional.

Recommendations for Control and Mitigation of Laurel Wilt and Ambrosia Beetle Vectors in Commercial Avocado Groves in Florida

Control of the LW pathogen–AB complex is challenging due to the potential for rapid root-graft transmission, new LW infestations caused by AB movement, and the difficulty and expense of current control tactics. Ongoing research is aimed at further understanding of the biology of the pathogen and secondary AB capable of transmitting the LW pathogen, epidemiology (spread dynamics of the disease), and development of more efficient control and mitigation tactics. As more information is developed, control recommendations will be revised.

Sampling Guidelines and Recommendations for Submitting Samples for Diagnosing Laurel Wilt in Avocado Trees (Persea americana L.)

Laurel wilt (LW) is a vascular disease caused by a fungal pathogen, Raffaelea lauricola, which is transmitted to avocado trees by several ambrosia beetle species or through root grafts among adjacent avocado trees. Laurel wilt is a highly destructive disease that ultimately results in tree death; therefore, early detection and tree removal to prevent its spread is recommended. Diseased or symptomatic trees are best identified by continuous and regular grove scouting, which should be a normal grove management activity. This may go a long way to manage the disease and remain in business.

Avocado trees are a popular choice for homeowners in Florida, with over 600,000 growing in Florida home landscapes. However, avocado trees as well as others in the Lauraceae family are susceptible to laurel wilt disease, which can kill a tree in as few as three weeks.

Los aguacates cultivados en patios y jardines son disfrutados y apreciados por cientos de residentes de Florida. Además de proveer sus frutos, estos árboles ofrecen un hábitat para la vida silvestre y sombra en las áreas urbanas. Existen aproximadamente 600,000 árboles de aguacates en los patios y jardines de Florida. La mayoría de estos árboles se encuentran en los condados de Miami-Dade, Broward, Palm Beach, y Lee en el sur de la Florida, pero también se encuentran en muchos de los condados centrales de Florida.

A Basic Guide to Mushrooms Commonly Encountered in Potted Plants in Florida

Elena Karlsen-Ayala, Romina Gazis, and Matthew E. Smith

Mushrooms growing in potting soil are a common problem reported in nursery production and in potted plants in the indoor and outdoor home landscape. Many of these fungi are saprotrophic and feed on the organic matter contained in the potting soil itself and/or in the mulch, which varies in composition but often contains tree bark, wood chips, pine straw, moss, or leaves. These fungi are not necessarily harmful to the plants, but fungal fruiting bodies can make plants unmarketable. Unknown fungi can also be concerning to retailers and homeowners because of potential toxicity to pets and children. The purpose of this publication is to provide homeowners and retail nursery growers with an overview of some of the most common mushroom-forming fungi found in potted plants and potting soils in Florida. We also provide cultural control recommendations to help prevent or reduce mushroom growth.

En verano del 2010, en viveros de Homestead se reportaron casos de Ficus elastica con manchas foliares circulares que se asemejan a los síntomas causados por la bacteria fitopatógena Xanthomonas campestris pv fici, aún no reportada en Ficus elastica. El daño severo affectó a la mayoría de los productores comerciales del sur de la Florida.
