“NIFA’s Emergency Citrus Disease Research and Extension program brings the nation's top scientists together with citrus industry representatives to find scientifically sound solutions to combat and prevent HLB at the farm-level,” said NIFA Director Dr. Carrie Castille. “This year’s awards represent all three major U.S. citrus growing regions and include possible solutions ranging from blocking HLB transmission from inside the insect vector to utilizing novel anti-microbial peptides to treat HLB-infected trees.”
The fiscal year 2021 five funded Emergency Citrus Disease Research and Extension projects include:
- Texas A&M AgriLife Research will leverage public-private partnerships between state agencies, universities, USDA’s Agricultural Research Service, and the citrus industry to pursue advanced testing and commercialization of promising HLB therapies and extend outcomes to stakeholders. ($7,000,000)
- University of California, Riverside will build on previous work and evaluate the performance of 300 hybrid citrus trees in established trials to map HLB tolerance/resistance genes and release superior new rootstocks. ($1,499,998)
- University of Florida seeks to develop a bacterial pathogen transmission blocking strategy (specifically to block Candidatus Liberibacter asiaticus, the pathogen that causes HLB) toward mitigation of citrus greening-related losses in an integrated pest management framework. ($1,020,810)
- University of Florida’s project will support the needs of both commercial and residential citrus growers by comparing new tools to support young trees and develop management recommendations for the incorporation of each tool into production and residential settings. ($750,000)
- University of Florida aims to introduce and transfer the natural HLB resistance present in Australian limes into conventional citrus to produce HLB-resistant Australian lime hybrid rootstocks and deploy these hybrids to protect susceptible citrus scions against HLB. ($500,000)
NIFA invests in and advances agricultural research, education, and Extension across the nation to make transformative discoveries that solve societal challenges. NIFA supports initiatives that ensure the long-term viability of agriculture and applies an integrated approach to ensure that groundbreaking discoveries in agriculture-related sciences and technologies reach the people who can put them into practice. In fiscal year 2020, NIFA’s total investment was $1.95 billion.
