The Florida Citrus Commission (FCC) on May 18 received an update on a propagation program intended to quickly produce and commercialize trees showing tolerance or resistance to HLB disease, also known as citrus greening. The program will focus on the Donaldson tree and other escaped trees. The Donaldson is a tree at the U.S. Department of Agriculture’s Whitmore Farm that …
By Anirban Guha and Christopher Vincent A quick body temperature test is common these days before entering many workplaces, hospitals and clinics due to the ongoing COVID-19 pandemic. The purpose is to screen people for fevers, usually with a non-contact infrared thermometer. Measurement of plant body temperatures also has become common for many field crops, not to screen for infectious …
U.S. Representatives Kat Cammack and Al Lawson led members of the Florida congressional delegation to ask the U.S. Environmental Protection Agency (EPA) for expeditious approval of Vismax, a biochemical pesticide for HLB. A letter from the representatives asks the EPA to rapidly approve the use of Vismax in preventing HLB so the industry may access this product before the start …
By Lauren Diepenbrock, Megan Dewdney, Fernando Alferez, Jawwad Qureshi and Ozgur Batuman Individual protective covers (IPCs) are becoming commonplace in citrus production to support the development of young trees after planting. IPCs are made of fine mesh and are intended to keep Asian citrus psyllids (ACP) off young plants. Because ACP can transmit the pathogen that causes citrus greening/huanglongbing, preventing …
By Davie Kadyampakeni and Evan Johnson In the era of citrus greening disease (huanglongbing, HLB), maintaining optimal nutrition and disease/pest management strategies is critical for avoiding adverse effects on tree performance. Use of the right fertilization rate, timing and placement are important for optimal citrus production. In a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research study, …
Although a Fundecitrus researcher recently called the HLB situation in Brazil “alarming,” the organization says the industry has the knowledge needed to manage the disease. HLB is also known as citrus greening. “The management package exists and is efficient. The problem is that, in order to reduce costs, it is not applied rigorously, correctly and in an integrated manner,” said …
It often takes time for the damage associated with freeze events to manifest in citrus. That was the case for the late January freeze in Florida. While some growers escaped fairly unscathed, others suffered significant damage. The damage began to show in the U.S. Department of Agriculture’s March citrus crop forecast. The agency lowered expected production of Florida oranges this …
By Amir Rezazadeh Huanglongbing (HLB), or citrus greening disease, has caused more than 70% decline in the production of oranges for juice and the fresh market in Florida. Once a tree is infected, there is no cure. Early detection followed by a rapid response is important to avoid further spread of the exotic pathogen. Delayed detection of HLB can result in …
Growing Matters, funded by a consortium of agricultural chemical companies, recently launched its fourth annual BeSure! campaign to promote best management practices when using neonicotinoid products on farms and urban landscapes. The campaign uses a wide range of media channels to remind growers, crop protection applicators and others to ensure label directions and responsible stewardship measures are followed for neonicotinoid …
A small amount of citrus greening disease (huanglongbing or HLB) can escalate quickly if growers are not careful. Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, cautioned producers about the disease during the recent Georgia Citrus Association meeting. “The issue is not widespread yet (in Georgia) for sure,” said Oliver. “We don’t think the vector is …
By Brad Turner As I started my regenerative journey five years ago, it conjured up memories of walking the family groves in the 1970s with my freshly sharpened eye hoe. I would follow the tractor as it pulled the offset chopper, crisscrossing between the widely spaced trees in all directions. The native grasses and broadleaf plants — including legumes like …
Finger limes will be the topic of a March 23 virtual symposium sponsored by the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center (UF/IFAS CREC). Finger limes are a unique citrus variety gaining interest among chefs, foodies and citrus growers. The symposium, targeted to commercial citrus and specialty crop growers and marketers, will be …
By Lindy Savelle Earlier this year, a small grove owner in Grady County, Georgia, noticed some odd-looking trees in his grove. The leaves, having an asymmetrical discoloration, appeared to be nutritionally deficient. In an attempt to remedy the problem, the grower reached out to the Grady County Extension office for help. The Extension agent began his quest to figure out …
Consumers are more likely to buy orange juice (OJ) if they think the fruit comes from Florida, new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research shows. In fact, top reasons consumers purchase OJ include taste, health benefits and origin of the fruit. According to the Florida Department of Citrus (FDOC), while 80% of OJ consumers who …
Florida citrus growers and orange juice processors are reporting low Brix levels as the 2021–2022 harvest season continues. The Jan. 10 edition of the Market News Bulletin from Florida Citrus Mutual noted average Brix of 9.83. According to Bob Behr, chief executive officer of Florida’s Natural Growers, juice oranges being harvested now are running below average. “Citrus greening continues to …
One instance of fruit drop is expected and needed every growing season for Florida citrus producers. A second instance, however, is unexpected, unwanted and just what growers do not need right before harvest time. HLB WORSENS DROPBut that is a scenario Florida citrus growers encounter every year. This problem has only worsened in the era of citrus greening disease, also …
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 …
Costa Rica’s orange production is expected to rebound to 300,000 metric tons in the 2021-2022 season, pushing total orange juice exports slightly higher to 33,000 metric tons. That estimate was issued by the U.S. Department of Agriculture’s Foreign Agricultural Service in December. Orange production in Costa Rica was 290,000 metric tons in 2020-21 and 285,000 metric tons in 2019-20. …
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 …
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 …
