KANSAS CITY — USDA’s National Institute of Food and Agriculture (NIFA) recently awarded 12 grants totaling over $45 million for research to combat Huanglongbing (HLB), commonly known as citrus greening disease.
“USDA-NIFA’s Emergency Citrus Disease Research & Extension (ECDRE) program brings the nation’s top scientists together to tackle this problem,” said Parag Chitnis, NIFA’s acting director. “This research is critical to help farmers find scientifically sound solutions to citrus greening so they can continue to grow citrus crops in a financially sustainable way. We hope this latest round of grant support moves us closer to a viable solution.”
Although citrus greening is a serious threat to the citrus industry worldwide, significant progress has been made to coordinate a multipronged approach for citrus greening management and suppression of the Asian citrus psyllid, an insect that carries and spreads HLB, through expanding partnerships with USDA’s Animal and Plant Health inspection Service, states, universities, and private partners.
Here is the list of the 12 ECDRE grants funded by NIFA in this FY2020 release:
