About four years ago, Fernando Alferez started to test whether citrus trees grown inside protective mesh covers could be kept safe from the HLB-spreading Asian citrus psyllid. New research from Alferez shows that citrus trees grown under individual protective covers (IPCs) show no signs of HLB, also known as citrus greening. Specifically, scientists found that psyllids cannot penetrate the IPCs …

However, FAS cautioned that exports could be lower “if higher-than-normal freight costs and limited shipping options continue.” Israel is seeking new export markets that will be able to absorb its produce with …
Texas Researchers to Lead HLB Project
Scientists from Texas A&M AgriLife Research will lead a public-private collaboration across Texas, Florida, California and Indiana to advance new, environmentally friendly and commercially viable HLB control strategies. The $7 million, four-year AgriLife Research project is part of an $11 million suite of grants from the U.S. Department of Agriculture National Institute of Food and Agriculture. In addition to Texas …
Legislators Want Grapefruit Decision Reversed
Members of the Florida and Texas congressional delegations recently urged the U.S. Department of Agriculture (USDA) to reverse its decision to administratively suspend juice content standards for imported grapefruit. The delegations also requested information regarding the circumstances of the suspension, which was allegedly made without a proper rulemaking process, and for which Congress was not notified. The request was led by …
HLB Quarantines Established in Alabama
Effective immediately, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS), in cooperation with the Alabama Department of Agriculture and Industries (ADAI), is establishing new quarantines for huanglongbing (HLB; citrus greening disease). The new quarantines are effective in all areas of Baldwin and Mobile counties in Alabama. APHIS is taking this action because of HLB detections in …

The company reported this in federal Securities and Exchange Commission filings released Tuesday. Alico said it harvested 6.4 million boxes of fruit during the year, …
Field Day to Feature GA and Nutrition Trials
Growers will have the opportunity to learn more about recent citrus research trials on nutrition and gibberellic acid (GA) and their impact on tree health. University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension Polk County will host a field day on Dec. 14 to share research findings with growers. The field tours will begin with an overview …
Medfly Quarantine in Southern California
A portion of San Bernardino and Los Angeles counties have been placed under quarantine for the Mediterranean fruit fly (Medfly) following the detection of two wild flies in and around the city of Upland in San Bernardino County. The U.S. Department of Agriculture (USDA), California Department of Food and Agriculture (CDFA), and the San Bernardino and Los Angeles county agricultural …
Pummelo Interstocks Could Improve Performance of HLB Trees
By Manjul Dutt, Ethan Nielsen, Lamiaa Mahmoud, Maria Quirico and Jude Grosser All commercially cultivated citrus scion varieties are grafted onto rootstocks before being planted in the field. The rootstocks are selected based on specific desirable qualities (abiotic/biotic stress resistance) and the ability to produce a good crop in a specific location. The ideal rootstock confers disease resistance, hardiness, tolerance …
Scout for Problems, Even in CUPS
Growers should monitor for pests and diseases, even in the citrus under protective screen (CUPS) systems designed to keep HLB-spreading psyllids out of trees, according to entomologist Jawwad Qureshi. He told more than 25 people participating in a Dec. 1 virtual seminar that CUPS “are not foolproof systems,” and said citrus can’t be grown successfully without pest management. Qureshi works …
How to Own Your Data and Profit From It
With the rapid development of artificial intelligence, data derived from farms might be more valuable than the crops growers produce. That’s because farmers can make money from their information when companies use it for other purposes, says a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) scientist. The key for producers is to take ownership of their information. …
