  • Crop Profile for Avocados in Florida
    Crop Profile for Avocados in Florida Prepared: August, 2008 Production Facts • As of 2002, the Florida avocado industry consisted of about 6,600 bearing acres, 737 growers, and 35 registered handlers/shippers. The majority of avocados (80 percent) produced in Florida are sold outside the state. Permits must be obtained for anyone wishing to sell more that 55 pounds of avocados per day. Consequently, most are sold to packinghouses from the farm (1). • In 2004-2005, Florida produced an estimated 28,000 tons of avocados. The value of the 2004-2005 crop was approximately $14.5 million or $0.26 per pound (1). • In 2004-2005, Florida was second behind California in avocado production nationally. Florida accounted for 9 percent of the production nationally, but only accounted for 5 percent of the value, owing to the fact that Florida avocados sell for less than the price (on a weight basis) garnered by California avocados (1). • Three “races” of avocado are recognized: West Indian, Guatemalan, and Mexican. These differ in blooming/maturity season, development period, fruit size, skin texture/color, oil content, and cold hardiness. West Indian and West Indian- Guatemalan hybrid cultivars predominate in Florida (2). • Avocado may be self- or cross-pollinating, and they are separated into A and B varieties based on reproductive functionality (2). Production Region Avocado (Persea americana) is grown exclusively in south Florida. Over 99 percent of Florida-grown avocado is produced in Miami-Dade County. Of the 737 farms reported in 2002, 88 percent were less than 15 acres, accounting for about a third of production, while those 50 acres and above (5 percent) accounted for approximately half of the production.

Ridley2 1The New Zealand Institute for Plant & Food Research Limited, Private Bag 4704, Christchurch, New Zealand 2Environmental Protection Authority, PO Box 131, Wellington 6140, New Zealand Corresponding author: [email protected] Abstract Two New Zealand statutes have important implications for research with organisms not previously found in New Zealand and either incidentally or illegally introduced. The Biosecurity Act 1993 and the Hazardous Substances and New Organisms Act 1996 define the legal framework and allowable activities for ‘unwanted’ and ‘new’ organisms, respectively. Aspects of these Acts that are relevant to research activities possible with plant pest and disease organisms after their discovery, in particular those organisms requiring rapid development of management strategies and tools, are summarised. The need for accurate, detailed and accessible lists of ‘unwanted’ and ‘new’ organisms, and the need for the Ministry for Primary Industries (MPI) and the Environmental Protection Authority (EPA) to respond rapidly when the status of these organisms needs to be changed is highlighted. Consideration should be given to making the legislation concerning ‘new’ organisms more applicable to incidentally or illegally introduced organisms.

  • Tropical Fruits, 2Nd Edition, Volume 1 R.E
    CROP PRODUCTION SCIENCE IN HORTICULTURE SERIES Series Editor: Jeff Atherton, Professor of Tropical Horticulture, University of the West Indies, Barbados This series examines economically important horticultural crops selected from the major production systems in temperate, subtropical and tropical climatic areas. Systems represented range from open fi eld and plantation sites to protected plastic and glass houses, growing rooms and laboratories. Emphasis is placed on the scientifi c principles underlying crop production practices rather than on providing empirical recipes for uncritical acceptance. Scientifi c understanding provides the key to both reasoned choice of practice and the solution of future problems. Students and staff at universities and colleges throughout the world involved in courses in horticulture, as well as in agriculture, plant science, food science and applied biology at degree, diploma or certifi cate level will welcome this series as a succinct and readable source of information. The books will also be invaluable to progressive growers, advisers and end-product users requiring an authoritative, but brief, scientifi c introduction to particular crops or systems. Keen gardeners wishing to understand the scientifi c basis of recommended practices will also fi nd the series very useful. The authors are all internationally renowned experts with extensive experience of their subjects. Each volume follows a common format, covering all aspects of production, from background physiology and breeding to propagation and planting, through husbandry and crop protection to harvesting, handling and storage. Selective references are included to direct the reader to further information on specifi c topics. Titles available: 1. Ornamental Bulbs, Corms and Tubers A.R.
