Ginger, galangal, and turmeric (Figure 1) are emerging crops for Florida production. All of these plants are in the Zingiberaceae family and share most aspects of their production. This publication describes production in containers or the field under Florida conditions to help guide growers interested in ginger, turmeric, and galangal production or expanding their market. All species have been evaluated by the UF/IFAS Assessment of Non-native Plants in Florida’s Natural Areas (UF/IFAS Assessment) using the Predictive Tool (an invasion risk assessment) and all present a low risk of invasion in Florida (https://assessment.ifas.ufl.edu).

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

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.

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.

Planning for a Successful Commercial Subtropical/Tropical Fruit Grove

Jonathan Crane, Yuncong Li, Edward Evans, Fredy Ballen, and Jeff Wasielewski

Planning is the key to successful grove establishment, maintenance, and production. Developing a detailed infrastructure description and plan, cultural program, and financial and marketing plan for a new or existing grove with a new fruit crop will save you time and money and help minimize mistakes. Prospective growers should compile and analyze information needed to select a grove site, establish the needed infrastructure, and develop maintenance plans for the plants and how the production will be marketed. This publication presents an outline of the type of information growers need when establishing a tropical fruit grove or contemplating management or modification of an existing grove.

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.

Quick Guide to Environmental Factors Impacting Subtropical and Tropical Fruit Crops in Florida

Jonathan H. Crane, Bruce Schaffer, Young Gu Her, Haimanote K. Bayabil, Jeff Wasielewski, yClyde Fraisse

Commercial tropical fruit crop acreage is expanding in Florida outside the traditional extreme south Florida and coastal counties. This largely results from the significantly warmer climate, less frequent freezing events, and less severity and duration of freezing events throughout the state, especially south-central counties. In addition, as the loss of citrus acreage continues, citrus growers and entrepreneurs are seeking alternative crops to remain in business. The successful establishment and maintenance of tropical and subtropical fruit crops in Florida depend on the crop’s tolerance to critical abiotic factors, including tolerance to flooded or waterlogged soil conditions, its ability to withstand high soil and irrigation water salinity, and its high and low temperature ranges for growth, flowering, and production. This publication aims to provide an understanding of the impacts of environmental factors on subtropical and tropical fruit crops grown in Florida.

The Lychee Erinose Mite Aceria litchii (Keifer) (Acari: Eriophyidae)

The lychee erinose mite is an important pest of lychee and is found in lychee-producing countries in Asia and South America and in Australia, Hawaii, and Brazil, where it has has caused an estimated 70–80% yield reduction and a 20% increase in production costs. Found in Lee County, Florida, in 2018, it has since spread to several counties in central and south Florida. The Florida Department of Agriculture and Consumer Services , Division of Plant Industry established an eradication program and a quarantine in Lee county. Management in other countries includes chemical control in combination with pruning. The purpose of this publication is to provide an in-depth profile of the lychee erinose mite. It is intended for the use of interested laypersons with some knowledge of biology as well as academic audiences.

El Ácaro de la Erinosis del Lichi, Aceria litchii (Keifer) (Acari: Eriophyidae)

El ácaro de la erinosis del lichi es una plaga nativa de Asia que ha sido reportada en varios países. En Brasil ha causado pérdidas y ha incrementado los costos de producción en un 20%. También en India se ha reportado una reducción del 80% en el rendimiento. En 2018, el LEM fue encontrado en el condado de Lee, Florida y luego en otros del centro y el sur del estado. En consecuencia, la División de Industria Vegetal del Departamento de Agricultura y Servicios al Consumidor del estado de Florida estableció un programa de erradicación y cuarentena en el condado de Lee. Esta publicación brinda un perfil a profundidad del ácaro de la erinosis del lichi y está dirigida a personas interesadas con conocimiento de biología, así como a una audiencia académica.

This factsheet provides information about the history of soil testing calibrations and justification for recommending extraction of soil nutrients using Mehlich-3 for calcareous soils in Miami-Dade County. The dominant soils from this County have an extraordinarily high concentration of calcium resulting in high pH. This document also includes UF/IFAS approved Mehlich-3 extractant-based testing interpretations and recommendations for these soils. The purpose of this publication is to elucidate an appropriate approach for analyzing the unique calcareous soils from Miami-Dade County for plant available nutrients. The target audiences are Extension agents, agronomists at soil testing laboratories, crop advisors, growers, representatives of the state and local agencies, and others concerned about soil testing and plant analysis in Miami-Dade County.
