As temperatures increase across Florida, so does the risk for huanglongbing (HLB) disease, known as citrus greening. While the southern and central portions of the state remain vulnerable to HLB and Asian citrus psyllids (ACP) that spread the disease, growers in North Florida and South Georgia have so far been spared. But Xavier Martini, University of Florida entomologist at the …
By Nabil Killiny and Christopher Vincent The citrus industry has suffered numerous setbacks over the past 20 years because of the devastating effects of huanglongbing (HLB) disease. Many options for controlling the disease are being investigated to make groves as productive as possible under the current HLB pressure. Even small improvements in tree health or yield of diseased trees may …
Sometimes growers must think outside the box to remain sustainable amid high input costs and devastating diseases. That is the situation facing citrus growers who are struggling to remain viable in the era of citrus greening. What if seaweed could be used to aid in the quality of citrus production? Seaweed is a biostimulant that is part of the biological …
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 …
By Marcelo Pedreira Miranda, Haroldo Xavier Linhares Volpe, Renato Beozzo Bassanezi, Ivaldo Sala and Juliano Ayres Huanglongbing (HLB), or citrus greening, is a notable threat to the citrus industry worldwide and was reported in the central region of São Paulo state (SPS) in Brazil in 2004. HLB then spread quickly throughout SPS, requiring the citrus industry to adapt rapidly to …
Researchers at the California Data Analysis and Tactical Operations Center (DATOC) have analyzed Asian citrus psyllid (ACP) trapping data along major transportation routes before and after tarping regulations for bulk citrus shipments were enacted. The purpose was to determine the effectiveness of the policy. DATOC is an independent group of scientists sponsored by the Citrus Research Board and the California …
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 …
Florida citrus production has decreased for almost two decades. According to Marisa Zansler, director of economic and market research at the Florida Department of Citrus, the two main factors for the state’s steady decline are citrus greening (huanglongbing, known as HLB) and Hurricane Irma. Zansler presented staggering statistics during the Florida Agricultural Policy Outlook Conference on Feb. 26 that showed …
Fertilizers help crops reach maximum yields while fungicides prevent diseases. But what if there were products available that could further enhance the fruiting qualities all growers hope to achieve every season? IMPROVED FRUIT PRODUCTIONIf growers can increase the level of flowering hormones in their crops, this will allow for a better fertilization process that will generate improved fruit set and …
By Jawwad Qureshi Managing the Asian citrus psyllid (ACP) is critical because of its role in spreading huanglongbing (HLB). Biological control is one method for ACP control. It is essential for developing integrated and sustainable pest management strategies. Biological control has always been a vital component of citrus pest management in Florida; understanding its contribution to the mortality of ACP …
Fermented food waste converted to liquid fertilizer and fed through drip irrigation can boost bacteria that increase crop growth, according to a new University of California Riverside (UCR) study. The treatment may also make plants more resistant to pathogens. “Beneficial microbes increased dramatically when we added fermented food waste to plant growing systems,” said UCR microbiologist Deborah Pagliaccia, who led …
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 …
Florida’s citrus growers are counting on research to help sustain what’s left of an industry decimated by huanglongbing (HLB). The disease remains a focal point of research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Scott Angle, vice president for agriculture and natural resources at UF/IFAS, understands the ramifications if improved HLB management options aren’t available …
Jim Gorden, chair of the Citrus Pest and Disease Prevention Committee (CPDPC), is greatly concerned about the increase in sporadic Asian citrus psyllid (ACP) detections across California. Gorden sent an open letter to all citrus growers asking them to increase their vigilance against the pest and the risk of citrus greening, known as HLB disease. He said that “While the …
Researchers Caroline Roper and Nichole Ginnan at the University of California, Riverside led a large research collaboration that sought to explore the microbiome’s role in HLB disease progression. Their recent article in Phytobiomes Journal, “Disease-Induced Microbial Shifts in Citrus Indicate Microbiome-Derived Responses to Huanglongbing,” moves beyond the single-snapshot view of the microbial landscape typical of microbiome research. Their holistic approach …
By Jawwad Qureshi Several studies have documented the positive effects of controlling the Asian citrus psyllid (ACP, Figure 1) for citrus tree health and sustainability in Florida. The mature blocks established before and after the discovery of huanglongbing (HLB) in 2005 continue to benefit from psyllid control. One psyllid is enough to infect a tree with HLB for life, and …
By Lauren Diepenbrock Pest management is an ongoing effort in Florida citrus. Taking advantage of pest life cycles, whether they are tied to the season or plant phenology, can make management efforts have greater impacts on pest populations. For many citrus growers, managing the impacts of Asian citrus psyllid (ACP), the vector of huanglongbing (HLB), is part of the annual …
A citrus tree at a private residence near San Diego, California, has been found to be infected by four Asian citrus psyllids (ACP). Upon testing, the ACP were found to be carriers of the bacterium that causes citrus greening, also known as huanglongbing (HLB). The finding was announced by the California Department of Food and Agriculture’s Citrus Pest and Disease …
UC Riverside scientists are working to breed new fruits that are naturally resistant to huanglongbing (HLB). The hybrid fruits will ideally share the best of their parents’ attributes: the tastiness of citrus and the HLB resistance displayed by some Australian relatives of citrus. HLB, also called citrus greening disease, has been detected in California, where 80 percent of the country’s …
Now is the time of year for gifting fresh citrus to family and friends to enjoy. Unfortunately, people are not the only ones who enjoy eating citrus. Numerous pests can be found feasting on various plant parts in the grove. Keeping pests under control is the theme of the January issue of Citrus Industry magazine. Of course, the most concerning …
