2019 RFP Priorities

All research pre-proposals must address at least one of the priorities below.

  1. Bactericide use in Florida citrus groves.

a.   Develop commercially viable bactericide application technologies.
b.  Improve the uptake of bactericides into citrus phloem.
c.  Develop tools to accurately measure and track live bacterial titers in citrus trees.

  1. Asian citrus psyllid (Diaphorina citri) and other pest management tools and strategies.

    a.  Develop or improve sound Integrated Pest Management tactics for citrus pest management in an HLB era. (Research topics could include natural enemies, deployment of covers, barriers, psyllid repellants, reflective mulch, RNAi technologies, pheromones, and interactions between pesticides and other pests [e.g., rust mites])
  2. Horticultural practices for HLB disease management.

    a.  Develop management practices (e.g. tree spacing, irrigation, nutrition, pruning, etc.) to treat HLB trees to restore or prevent further decline of roots, fruit quality, enhanced fruit taste, yield and/or prevention of premature fruit drop.b.  Develop specific management practices for new and existing rootstock and scion combinations for fresh and processed fruit.
  3. Plant Improvement in an HLB era
    Develop field evaluation of CLas/ACP tolerance or resistance in rootstock and scion combinations for fresh and processed fruit.
  4. Management of interactions between HLB and other citrus diseases and pestsa.  Investigate HLB interactions with other citrus diseases (e.g., citrus canker, citrus black spot, blight, CTV) or pests.
    b.  Investigate the susceptibility of released rootstocks to root pathogens and pests including nematodes, Diaprepes root weevil and Phytophthora.
    c.  Investigate HLB interactions on pre and post-harvest fruit quality and shelf life of new varieties and juice blends.
  5. Citrus diseases other than HLB, including diseases not yet in Florida
