This federal Project Grant award from the United States Department of Agriculture's National Institute of Food and Agriculture (NIFA) under the Specialty Crop Research Initiative (SCRI) program, CFDA No. 10.309, provides $1,496,328.00 to the Agricultural Research Service (ARS) for a research project to address Huanglongbing (HLB) disease in citrus crops.

The key products and services to be delivered under this 3-year grant, running from January 1, 2025 to December 31, 2027, include:

  1. Exploring the use of the NMV-M/CFL virus as a biocontrol agent to suppress HLB in citrus trees, and identifying citrus varieties (scions and rootstocks) that can tolerate high viral and HLB bacterial titers.
  2. Developing and optimizing an NMV-M/CFL-based expression vector to deliver antimicrobial agents or RNA interference molecules to combat HLB and its insect vector.
  3. Conducting outreach and extension activities to disseminate the project's research findings to citrus growers, stakeholders, and the public.

This research aims to develop effective solutions for managing HLB, a critical challenge facing the specialty crop industry, through a multifaceted approach of biological control, genetic resistance, and delivery mechanisms.
