The citrus grove of the future and its implications for huanglongbing management

Ed Stover, William S. Castle, Peter Spyke


Revolutionary changes face Florida’s citrus industry as huanglongbing (greening) becomes widespread. Changing economic realities have encouraged many tree fruit industries to modify planting density, tree architecture, training and production systems. More trees/acre translate into earlier bearing and less yield disruption as trees die, but with greater establishment costs per acre. A model for citrus production, which may permit profitable production in Florida using huanglongbing susceptible material, has been called an Advanced Production System combined with Open Hydroponic System. These practices have been adopted in a number of citrus producing countries, but need to be evaluated and adapted to Florida conditions. Practices that facilitate early cropping and fruit quality are critical to high density orchard profitability. Control of water and nutrients to manage tree development, girdling, use of plant growth regulators, larger planting stock, and tree supports may maximize early yields and help contain canopy volume. In the more distant future, genetic improvement solutions may contribute additional tools. The purpose of this paper is to stimulate discussion, facilitate assembly of diverse useful ideas in facing this challenge, and coordinate efforts within Florida to get a critical mass of production and economic data as quickly as possible.
