Scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are testing a new type of citrus tree that can fight off the HLB-spreading Asian citrus psyllid (ACP). The genetically modified tree has only been tested in the lab and the greenhouse but is very promising as a potential solution to HLB. The approach involves inserting a …
Australia’s New South Wales (NSW) Government has partnered with the Australian Centre for International Agricultural Research and Hort Innovation to prepare the citrus industry against huanglongbing (HLB). Although widespread in Asia and found in North and South America, HLB is not known to be present in Australia. The psyllid that spreads HLB is also absent from Australia. A collaborative research …
A December Florida TaxWatch report, The Continuing Decline of Florida’s Citrus Industry, highlights the causes of the industry’s demise in recent decades.

The quarantined area in the Mission Viejo area of Orange County expanded by approximately 85 square miles. …
Researchers with Brazil’s Fundecitrus discussed HLB-related topics at the recent 15th International Citrus Conference in South Korea. Fundecitrus’ Franklin Behlau participated in the section of papers related to HLB, also known as citrus greening disease. Most of the papers provided updates on the disease situation in different locations, including Florida, China, India, Nepal, Indonesia, Iran and Brazil. Behlau discussed the …
Texas A&M AgriLife Research scientists led by Kranthi Mandadi are seeking novel solutions to huanglongbing (HLB), also known as citrus greening disease. Mandadi is a professor in the Texas A&M Department of Plant Pathology and Microbiology and a researcher at the Texas A&M AgriLife Research and Extension Center at Weslaco. In the past few years, he and his collaborators have …
Fundecitrus and its cooperators released a second update to the 2024–25 orange crop forecast for Brazil’s São Paulo and West-Southwest Minas Gerais Citrus Belt. The Dec. 10 projection is 223.14 million 90-pound boxes. That’s an increase of 3.4% from September’s update but a 4% decrease from the initial May forecast of 232.38 million boxes. The forecast by orange variety, with …
The success of citrus under protective screen (CUPS) in protecting Florida citrus from citrus greening, also known as huanglongbing or HLB, was not surprising to Arnold Schumann. The professor of soil fertility and water quality at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center is thankful research had yielded a temporary solution …
By Romain Exilien and Xavier Martini Residential gardens serve as reservoirs for Asian citrus psyllids (ACP) and citrus greening disease (also known as huanglongbing or HLB) due to unmanaged citrus trees. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) conducted a survey to assess residents’ needs regarding ACP and HLB management. The survey examined their current control …
Climate change is a key reason that citrus production has progressed in South Georgia, North Florida and South Alabama, the area known as the cold-hardy citrus region. As more varieties, other than satsuma mandarins, continue to be planted in the area, warmer temperatures are needed for trees to flourish. Arnold Schumann, professor of soil fertility and water quality at the …
Two varieties that tolerate HLB and produce ample fruit yield and juice were the highlights of the recent Millennium Block Field Day in Fort Pierce, Florida. The 20-acre Millennium Block at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) examines fresh fruit varieties and rootstocks. “The two varieties that give …
Citrus canker has long been a presence and concern for Florida’s citrus growers. Growers in North Florida, South Georgia and South Alabama should be wary of its potential spread into the cold-hardy citrus region. Clive Bock, a research plant pathologist with the U.S. Department of Agriculture, spoke about the disease during the recent Cold-Hardy Citrus Meeting at the University of …
