University of Florida (UF) scientists achieved a major milestone in their quest to develop an HLB-resistant tree by sequencing the genome of a fruit plant that’s a close cousin to citrus trees. HLB is also known as greening disease. UF Institute of Food and Agricultural Sciences researchers sequenced the genome from trifoliate orange, in collaboration with scientists from the University …
Algal spot had rarely been seen in Florida groves until fairly recently, Megan Dewdney reported in a virtual Florida Citrus Growers’ Institute presentation. The University of Florida Institute of Food and Agricultural Sciences plant pathologist said she started hearing from concerned orange growers within the past five years.

The nation’s essential agricultural industry has worked relentlessly through the COVID-19 pandemic to ensure food is put on the tables of American families. Agricultural employers recognize that the health and safety of their employees are imperative to the success of their operations. These employers also recognize consumer demand for fresh, safe and nutritious produce. For years, agricultural employers have adhered …
By Ronald G. Doetch I am a lifelong farmer/agronomist and, at the age of 73, have worked with many different crops through the many changes in agriculture challenges and production practices. I moved to Florida four years ago to grow a few oranges and have a firsthand look and understanding of the relationship of soil health to tree decline and …
By Madison Sankovitz, Barbara Alonso, Monique Rivera, Lukasz Stelinski, Sara García-Figuera, Peggy G. Lemaux and Beth Grafton-Cardwell The bacterial disease huanglongbing (HLB) is a devastating disease and has caused massive losses to the U.S. citrus industry. The disease vector, the Asian citrus psyllid, is currently in all U.S. citrus-producing states, and the disease continues to exert a severe impact on …
Hop stunt viroid (HSVd) was found on citrus in Georgia for the first time this year. University of Georgia Cooperative Extension warns that HSVd and other viroids could pose a threat to the state’s growing citrus industry in susceptible varieties. Leaf samples were collected in May and June from 12 different citrus plants in two nurseries in southern Georgia. Nine …
A quarantine expansion has been declared following the detection of the citrus disease huanglongbing (HLB, also known as citrus greening) in five residential citrus trees located in Rancho Cucamonga, California. This is the first time the disease has been confirmed in Rancho Cucamonga, marking the fifth city in San Bernardino County to have had a positive detection of HLB. California …
Largely due to the advent of huanglongbing (HLB) disease, Florida orange production has declined by over 70 percent in the last 10 years. According to experts, if the trend is not reversed, processing plants will not have enough fruit to maintain production and profitability, ultimately causing shutdowns. Currently, Florida law requires that orange juice be comprised of at least 90 …
Megan Dewdney recently provided information about positive results from fungicide trials for citrus black spot, as well changes to the new Citrus Production Guide. Dewdney is a plant pathologist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), working at the Citrus Research and Education Center. Dewdney conducted the fungicide trials for black spot in a 20-year-old …
Citrus growers need every available tool to fight disease, reduce tree stress and keep groves healthy against Phytophthora root rot. According to the University of Florida Institute for Food and Agricultural Sciences (IFAS), Phytophthora root rot is one of the most important diseases threatening citrus yield. This disease can be caused by different species within the genus Phytophthora, a water mold in the …
Traditional data collection for pest and disease detection relies on manual sampling, which can be time consuming and labor intensive. But now, Florida citrus growers could have artificial intelligence (AI) technology to simplify the process, better care for their crops and save money. Yiannis Ampatzidis, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, discussed several new …
The use of individual protective covers (IPCs) for young trees prevented Asian citrus psyllid transmission and HLB infection in a trial near Immokalee, Fernando Alferez reported during the recent virtual Citrus Expo. Alferez said citrus trees planted at the Southwest Florida Research and Education Center (SWFREC) in January 2018 and covered with IPCs have been HLB-free for 32 months. Alferez …
U.S. News & World Report recently ranked the University of Florida (UF) the sixth best public university in the United States. Michael Rogers, director of the Citrus Research and Education Center (CREC), tells how a high ranking for UF can benefit Florida citrus. “This (the ranking) really attracts a lot of opportunities for the university,” Rogers says. He points out …
HLB-affected citrus trees benefit from micronutrients at higher-than-recommended rates, Tripti Vashisth reported in a virtual Florida Citrus Growers’ Institute presentation. Vashisth, a University of Florida Institute of Food and Agricultural Sciences researcher, said that a 20 percent higher-than-recommended rate of micronutrients can improve productivity in trees with HLB. The Florida Citrus Growers’ Institute is normally held in Avon Park in …
With the devastating impacts of HLB on the citrus industry, growers are seeking alternative solutions to reduce Candidatus Liberibacter asiaticus (the bacteria that causes HLB) levels in trees and prevent disease-induced decline. Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are developing an automated method for delivering therapeutic liquid materials into the vascular tissue of citrus …
Since many of the regions where citrus trees grow have warm, humid climates, bacterial and fungal diseases can easily run rampant. Preventative methods are the best way to control diseases in citrus, because if problems occur once new leaves, shoots and fruit are developing, it is likely too late to stop the disease during that growing season. Growers can use …
By Michelle Danyluk and Ben Chapman While there is no evidence that the COVID-19 virus is a food-safety concern, it certainly is a worker health concern. It spreads person-to-person through close contact (defined as within 6 feet for more than 15 minutes) or by contact with contaminated surfaces. Systematically walking through the grove, packinghouse or processing plant and thinking about …
