Psyllid sprays have been a point of contention for Florida citrus growers. Under endemic HLB conditions, high psyllid control costs have cut into the grower’s bottom line, which has already been hit by reduced production. So, what is the right time to spray and how can a grower remain sustainable and profitable? Lukasz Stelinski, University of Florida professor of entomology …
By Sylvia Willis, Amy Vu and Jamie Ellis When people think of Florida, the first thing that comes to mind is Fresh From Florida oranges. Florida accounts for 44 percent of total U.S. citrus production. Citrus, like many other fruits, vegetables and specialty crops, requires certain inputs to grow and produce fruit. But how are pollinators and the production of …
March’s All In For Citrus podcast brings news of in-person events, details on controlling the vector of HLB disease, as well as potential changes to nutrient and water management recommendations. Citrus Research and Education Center Director Michael Rogers begins the episode discussing several upcoming events for growers. On April 6, the Florida Citrus Growers’ Institute will return as a virtual …
By targeting Asian citrus psyllids on an area-wide scale and focusing on several individual properties simultaneously, growers can minimize psyllid movement between groves, reduce HLB transmission and maintain citrus production at a profitable level. Generally, most psyllid sprays are applied on a calendar or threshold basis, resulting in high-spray frequencies and associated costs. Because of the Asian citrus psyllid’s high …
By Emilie Demard and Jawwad Qureshi Managing the Asian citrus psyllid (ACP), a vector of huanglongbing (HLB), is critical for reducing disease incidence and improving tree health. Growing citrus under screened structures, referred to as citrus under protective screen (CUPS), protects trees from ACP and HLB. CUPS provides an opportunity to produce premium-quality fresh fruit by preventing psyllids and HLB …
As growers strive for sustainability in the HLB era, biological controls are playing an increasingly important role in citrus production. The March issue of Citrus Industry magazine features some of the latest biological control research. An article by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Jawwad Qureshi looks at three types of biological control agents used …
February’s All In For Citrus podcast brings good news about a new faculty position, an upcoming in-person meeting and Australian finger limes projects to battle HLB and keep growers profitable.

Citrus growers and industry members recently gathered virtually to discuss the Asian citrus psyllid (ACP) and huanglongbing disease (HLB) situation throughout the Central Valley of California. The reason for the concern is a negative trend seen in 2020. ACP DETECTION HISTORYACPs, the vectors for the disease, are widespread in Southern California where HLB-infected trees have been found. There are ongoing …
Visual identification of nutrient deficiencies and leaf damage is an important diagnostic tool for fine-tuning management of citrus. Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, shared how UF/IFAS researchers have used artificial intelligence (AI) to diagnose citrus nutritional deficiencies, diseases and pest damage. According to Schumann, disease and pest symptoms on leaves may cause …
While everyone strives to protect themselves from coronavirus disease, growers have an additional concern: protecting their trees from citrus disease. While HLB is of course the most damaging disease of citrus, there are other diseases that should not be overlooked. Disease management is the theme of the February 2021 issue of Citrus Industry magazine. University of Florida Institute of Food …
By Xavier Martini and Danielle Sprague Cold-hardy citrus, that is, citrus grown above the 30th parallel north, is a blooming industry. In less than 10 years, the acreage in North Florida has gone from almost nonexistent to approximately 1,000 acres. Growers in the region plan to plant more in the coming years. In Georgia, there are approximately 2,000 acres across …
An update on the nutrition box program, shade research with some positive side effects, and a bold project analyzing compounds used against HLB headline January’s All In For Citrus podcast. The Citrus Nutrient Management Program, more commonly known as the nutrition box program, is over a year old. Citrus Research and Education Center Director Michael Rogers, with the University of …
The U.S. Environmental Protection Agency (EPA) on Jan. 12 announced two actions to help protect America’s citrus industry from HLB and citrus canker. One action is for the insecticide aldicarb; the other is for the antibiotic streptomycin. ALDICARBEPA is registering one technical product, a supplemental label and one new end-use product for the insecticide aldicarb for use on oranges and …
Hurricanes, development, demographics, disease and other issues combined in recent decades to severely reduce citrus acreage and crops in Plaquemines Parish, which has the majority of Louisiana growers.

By Nian Wang, Fred Gmitter and Manjul Dutt Nearly all commercially important citrus types — oranges, grapefruits etc. — have originated by mutations that have accumulated over several hundreds to thousands of years, from what once was an original, individual sweet orange tree and a single grapefruit tree. The many different cultivars that we know today are descended from those …
The November episode of the All In For Citrus podcast covers a multitude of grant-funded research that the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus team both leads and collaborates on. Citrus Research and Education Center Director Michael Rogers begins the podcast with a discussion on research projects UF/IFAS scientists are playing critical roles in collaborative …
Citrus growers should consider controlling HLB-spreading Asian citrus psyllids (ACP) only when a prescribed ACP population, or threshold, is reached. Entomologist Lukasz Stelinski suggested this approach in a virtual Citrus Expo presentation. Stelinski is a University of Florida Institute of Food and Agricultural Sciences researcher at the Citrus Research and Education Center in Lake Alfred. A summary slide Stelinski showed …
