All of Zapata County has been added to the quarantined areas. The action was taken by the U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) in cooperation with the Texas Department of Agriculture (TDA). The action was taken …
A University of Miami (UM) doctoral candidate won third place in the UM College of Engineering’s Rothberg Catalyzer Pitch Competition for creating an instrument to quickly detect airborne traces of citrus greening disease. Shruti Choudhary’s creation, CitrusMimic, would be deployed on farming equipment to continuously draw in air and test for the citrus greening bacteria spread by the Asian citrus …

Organized by Citrus Australia, highlights of the event included the following: “Businesses across the supply chain had the opportunity to learn something new or make a connection that …
A California citrus leader believes Georgia will make an ideal home for the Asian citrus psyllid, which vectors the devastating huanglongbing (HLB) disease. “North of Florida, it is colder, and it’s certainly not as suitable a place as Florida is, but the psyllid is still going to be fine. The cold isn’t long enough here to knock the populations out,” …
Florida Citrus Mutual (FCM) recently reported that the Florida Legislature’s fiscal year 2024–25 budget includes $47 million to aid the state’s citrus industry. The funding for various programs is: Additionally, the Florida Legislature’s budget includes a $100 million annual appropriation for the Rural and Family Lands Protection Program, which aims to protect working agricultural operations from development by establishing conservation easements. …
A wider diversity of weeds and insects in organic Mexican citrus orchards compared to conventional orchards aids in control of the HLB-spreading Asian citrus psyllid (ACP/Diaphorina citri), a Mexican scientist reported recently. HLB is also known as citrus greening disease. “In the organic orchard, there are almost double the species of weeds compared to the conventional orchard,” Carlos Castillejos Cruz …
One California citrus leader believes Georgia should respond more aggressively to huanglongbing (HLB, also known as citrus greening) for the sake of the industry’s future in the state. Roger Smith, fourth-generation citrus producer and executive of AC Foods, spoke during the recent Georgia Citrus Association meeting in Tifton. He discussed the disease that devastated citrus production in Florida and could …
Living with huanglongbing (HLB) disease (citrus greening) is a much different process for citrus growers than protecting their crop from it. Growers in the cold-hardy citrus region are currently trying to keep the devastating disease out of their area. Industry experts like Michael Rogers, University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center director, are …
Production in the cold-hardy citrus region is still in its infancy. Growers and industry leaders need events like the Citrus Health Forum to obtain the necessary information to help this young industry continue to flourish. The latest forum took place at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center in Quincy …
By Jawwad A. Qureshi, Lauren Diepenbrock and Davie Kadyampakeni Protecting citrus trees from the Asian citrus psyllid (ACP) is critical to reducing the spread and severity of huanglongbing (HLB) disease. The frequent availability of viable shoots in young trees is attractive to psyllid colonization, feeding and oviposition events. UV-metalized reflective mulches reflect ultraviolet light, which is disturbing for some insects …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is reminding citrus growers that flower bud advisories are now being issued. The UF/IFAS advisories can help growers determine when to spray for HLB-spreading Asian citrus psyllids and when to stop spraying in an effort to protect pollinating bees. Tripti Vashisth, a UF/IFAS associate professor of horticultural sciences, will …
As recently as five years ago, Florida citrus growers did not routinely put individual protective covers (IPCs) on their trees as part of their grove management. Now, the mesh IPCs cover at least 1 million trees on about 17,000 acres, mostly thanks to experimentation by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez. IPCs keep …
By Xavier Martini and Romain Exilien Despite intensive control efforts, the Asian citrus psyllid (ACP), the vector of Candidatus Liberibacter asiaticus, the bacteria causing citrus greening, remains the most devastating pest of citrus. The ACP typically relies on tactile, visual and odor cues to detect its host. By combining an irritant, a visual masking and a true repellent, University of Florida …
By Fernando Alferez, Ute Albrecht, Ozgur Batuman, Jawwad Qureshi and Saoussen Ben Abdallah Individual protective covers (IPCs), which are psyllid-exclusion mesh bags, are increasingly being adopted to efficiently protect newly planted citrus trees from huanglongbing (HLB) infection. However, IPCs typically must be removed after two to three years due to tree growth. Early evidence indicates that brassinosteroids (Brs), a relatively …
Agriculture officials recently established a Mediterranean fruit fly (Ceratitis capitata or Medfly) quarantine and expanded an Asian citrus psyllid (ACP) quarantine, both in California. MEDFLYFederal and state agriculture officials on Oct. 18 established the Medfly quarantine in California’s Los Angeles County. The action was taken by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA APHIS) and …
By Amir Rezazadeh Citrus trees face many threats that can impact fruit development and overall tree health. Pests, including aphids, mites and other insects, can damage fruit and transmit diseases. Extreme weather events, such as hailstorms or heavy rains, can cause physical harm, leading to blemishes and reduced market value. In addition, citrus growers have faced persistent challenges because of …
Fundecitrus researcher Franklin Behlau lectured about canker and HLB and participated in other ways at the recent Asian Citrus Congress in Nagpur, India. His lecture addressed the advancement of HLB (also known as greening) in the Brazilian citrus belt and the work carried out by Fundecitrus in combating HLB and canker. Behlau also moderated a technical session and participated in …
The resistance of HLB-spreading psyllids to some insecticides and the low effectiveness of insecticides applied via drench to control psyllids were recently addressed by Fundecitrus researchers.
