A Closer Look at CUPS-Grown Grapefruit
By Arnold Schumann, Ariel Singerman and Yu Wang Grapefruit production in Florida has been drastically reduced by huanglongbing (HLB) disease, from 40.9 million boxes in 2003–04 to 4.5 million boxes in 2018–19, according to the U.S. Department of Agriculture. Grapefruit varieties are particularly vulnerable to HLB due to cumulative losses from stunted tree growth, low fruit yield, high-percentage fruit drop, …
Viruses in the Gut of Asian Citrus Psyllid: Friends or Foes?
By Ozgur Batuman and Amit Levy Management options for huanglongbing (HLB) are limited and rely heavily on insecticides for controlling Asian citrus psyllid (ACP) populations, even when integrated with other cultural control methods. Chemical strategies are expensive and, if not rotated, can contribute to the development of chemical resistance among ACP populations. In some cases, long-term chemical applications may have …
Psyllid Management: Organic and Conventional Systems
By Jawwad Qureshi Management of the Asian citrus psyllid (ACP) is needed in multiple environments, such as organic and conventional production systems and urban areas. However, the tools and approach may be different depending on the circumstances. Chemical control is the primary method used in commercial production to reduce psyllid populations, but the increased use of insecticides negatively affects the …

Orange Juice Consumption Declining at a Slower Rate
By Marcos Fava Neves An annual report on global orange juice consumption was recently completed. This report is based on data from CitrusBR (Brazilian Orange Juice Exporters Association), Tetra Pak, Euromonitor International, Planet Retail, the U.S. Department of Agriculture (USDA) and others. The report was first published in 2004. Decline in orange juice demand has been seen since then. The …
IPCs for HLB Prevention in Young Trees
By Fernando Alferez, Susmita Gaire, Ute Albrecht, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri Controlling the Asian citrus psyllid vector of huanglongbing (HLB) is critical, especially in young trees. Reducing HLB incidence is essential for tree survival and productivity under current endemic conditions. Individual protective covers (IPCs) are a novel strategy based on psyllid exclusion by means of a protective …
The Value of Education and a New Scholarship
By Ernie Neff Decades ago, Ned Hancock had a conversation with his father about the value of continuing his education at the University of Florida (UF). “Dad said, ‘You will learn more in the next few years than you may be able to remember, but I hope they teach you two important things: One, you don’t really know as much …
Steaming for Weed Management
By Ramdas Kanissery and Yiannis Ampatzidis Weeds are a significant problem in horticultural production and must be controlled to maintain good crop yield. Concerns related to non-judicious use of herbicides, which include ground and surface water contamination and pesticide residues in food, has sparked public awareness and restrictions on herbicide use. For these reasons, alternative and integrated systems for weed …
A Growth-Enhancing Pest Management Option
By Christopher Vincent Particle films can both increase tree growth and reduce Asian citrus psyllid populations. University of Florida (UF) research has found particle films delay infection with the CLas bacterium, which causes HLB. They also enhance growth rates and yield. Particle films do have limitations to efficacy, including being washed off in frequent or heavy rains. Overall, particle films …
New Citrus Pest in Hendry County
A new pest of Florida citrus has been found in the southwest region of the state. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock told growers in Sebring on Sept. 25 about recent finds of a cerambycid, or long-horned beetle, in Hendry County groves. Diepenbrock, who works at the Citrus Research and Education Center in …
Sneak Peek: October 2019 Citrus Industry Magazine
The October issue of Citrus Industry magazine features two tools growers can use against Asian citrus psyllids (ACP). There’s still no silver bullet for HLB, the disease ACP carries to citrus trees.

University of Florida (UF) citrus physiologist Christopher Vincent …
PIECES OF THE PAST: Teaching Northerners How to Eat Florida Grapefruit
By Brenda Eubanks Burnette I recently came across an article by Frank Kay Anderson in the June 1922 issue of Citrus Industry magazine and found it quite interesting, as I have never seen this version of a grapefruit “preparer.” It also made me wonder if this was one of the first fulfillment programs in the industry. So, if you have …
Does Reducing Psyllids Help When HLB Is Present Everywhere?
By Freddy Ibanez, Nabil Killiny, L. Gene Albrigo and Lukasz L. Stelinski With both Asian citrus psyllids (ACP) and huanglongbing (HLB) distributed throughout Florida groves, there is no longer a need to slow the spread of the disease. So, it is logical to ask whether reducing vector numbers is still something that is worth pursuing, given the investment needed in …
