Citrus Production

Integrated Pest Management

Integrated Pest Management (IPM) is a vital part of growing a healthy and productive citrus grove. Scouting is the first step in IPM. By monitoring the groves, it provides the opportunity to identify pests or a potential pest. The next step is the proper identification of a pest or their damage. Once a pest is identified, management decisions can be made and may consist of preventative controls, use of biological controls, and chemical management.

  • Insect Identification

    • Florida citrus hosts a wide array of arthropod pests including insects, mites and nematodes. These pests can cause damage to citrus through their feeding on fruit, foliage and roots. Indirectly, feeding wounds can serve as an entry point for plant pathogens. Some pests may also act as vectors of plant diseases such as the Asian citrus psyllid (Diaphorina citri) which spreads the citrus greening pathogen Candidatus Liberibacter asiaticus. Florida citrus also has numerous beneficial species that help to maintain most potential pests below economically damaging levels.

    Lebbeck Mealybug,

    Nipaecoccus viridis, is an exotic mealybug previously documented on dodder and tallow wood in Palm Beach County and intercepted at ports of entry. In June 2019, it was documented feeding on and damaging citrus in Highlands County, Florida. It is a known pest of citrus in the Middle East, Mediterranean, and Southern African regions. It has a wide range of hosts in Florida including: citrus, mango, pomegranate, grapevine, and several ornamental plants like hibiscus and mulberry.

  • Citrus Under Protective Screen (CUPS)

    • Citrus Under Protective Screen (CUPS) is an integrated system for growing citrus trees in protective screen houses for fresh fruit production. The screen is at least 40 to 50 mesh in order to exclude the Asian Citrus Psyllid [ACP] (Diaphorina citri), a vector of Huanglongbing disease (HLB).

    The Florida citrus nursery industry adopted a similar greenhouse or screen house production practice in the early 2000s in order to protect budwood sources and commercial citrus nursery tree production from citrus canker and ACP. The CUPS is very similar to the screen house citrus nursery system, but with a different goal:

  • Citrus Nutrition

    • A fertilizer program should include all mineral nutrients required by the plant. Every nutrient is indispensable and an excess or deficiency of any single nutrient can adversely affect tree performance. The goal of mature tree fertilization is to promote fruit set, growth, and development and, at the same time, ensure maintenance of tree health and fruit bearing surfaces in order to optimize yields for subsequent seasons. Fertilizer recommendations depend on a wide range of factors, such as soil characteristics, age of tree, variety and rootstock, and cultural practices.
