Citrus Disease Research and Extension Pre-App

Funding Agency:
US Department of Agriculture

​NIFA requests pre-applications for Emergency Citrus Disease Research and Extension (CDRE) for fiscal year (FY) 2018 to address priorities identified by the Citrus Disease Sub-committee (CDS) of the National Agricultural Research, Extension, Education, and Economics (NAREEE) Advisory Board through the integration of research and extension activities that use systems-based, trans-disciplinary approaches. 

The need to advance research and extension to develop management strategies for huanglongbing (HLB) has reached a critical juncture. Industry experts estimate that unless new strategies are found and made available, the Florida citrus industry will cease to exist in 2 years. The HLB epidemic in Texas is expanding at an increased pace and threatens to reach the severity seen in Florida over the same time scale. In California, the Asian citrus psyllid, which vectors the disease, has become endemic in important citrus production areas but HLB infection has only been found in isolated, non-production areas. Early detection tools are needed in the next 18 months to prevent HLB establishment statewide.


  • PRE-APPLICATION DEADLINE (Stakeholder Relevance Statement): Complete pre-applications must be received by 5:00 pm Eastern Time on June 29, 2018.
  • FULL APPLICATION DEADLINE (Only invited full applications will be considered) Complete, invited full applications must be received by 5:00 p.m. Eastern Time on September 24, 2018.

Areas of Interest

During the January 25 and 26, 2018 consultation, the CDS identified seven areas of highest priority for the current competition. Those areas, ranked by CDS for importance, are:

1. Therapies to prevent or suppress Candidatus Liberibacter asiaticus (CLas) bacteria within trees.

2. Development of tolerance or resistance in commercial citrus in all production areas with a focus on delivery of new cultivars (or rootstocks and scions) using all available strategies, with consideration of pathogen genetic diversity.

3. Improve productivity of infected trees, including root health.

4. Systems for delivery of therapies into the phloem of citrus trees, including the root system.

5. Culturing or cultivating the CLas bacterium 

6. Early detection of the bacterium in host and vector.

7. Development of pre- and post-harvest tools to maximize citrus fruit quality for use in fresh fruit or processed products.

Eligibility Requirements

Pre-Applications may only be submitted by Federal agencies, national laboratories, colleges and universities, research institutions and organizations, private organizations or corporations, State Agricultural Experiment Stations, Cooperative Extension Services, individuals, or groups consisting of two or more of these entities.

Amount Description

The anticipated amount available for CDRE in FY 18 is approximately $21.7 million. The CDRE pre-application process does not result in award recommendations. However, an estimate of project costs is required. The information in Section B should be used to develop the estimate. PLEASE NOTE: Indirect cost recovery for CDRE is capped at 22% of total federal funds.
