Excelsior Aerospace Corporation announced it is pursuing funding from the U.S. Department of Agriculture (USDA) to build a free tool that can rapidly detect, track and manage huanglongbing (HLB) disease. “On one end, our tool would serve growers in states such as Texas and California to detect early symptoms of ACP (Asian citrus psyllid) and HLB infection and take measures …
In the latest episode of the All In For Citrus podcast, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Kirsten Pelz-Stelinski discussed her research on the Asian citrus psyllid (ACP) and a new grant from the National Institute of Food and Agriculture to further her work. The goal of the research is to use bacteria already present …
The Florida legislative session is well underway in Tallahassee. The University of Florida hosted its annual Gator Day at the Capitol in February to remind lawmakers of all that the school does for its students and stakeholders. Michael Rogers, director of the Citrus Research and Education Center, and fellow citrus team members from the University of Florida Institute of Food …
The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has revised the conditions for interstate movement of citrus fruit from areas quarantined for both sweet orange scab (Elsinöe australis, SOS) and citrus canker (Xanthomonas axonopodis, CC). The revisions allow for the movement of fruit to packinghouses located in contiguous states that are not quarantined for either disease. …
Individual protective covers (IPCs) on citrus trees have become a more common sight in Florida groves in recent years. The bags that cover young trees exclude the Asian citrus psyllid (ACP) from feeding on the plants, thus protecting them from HLB. Some estimates suggest that more than 1 million IPCs are now deployed in the state’s citrus groves. During the …
By Jawwad A. Qureshi and Azhar A. Khan The Asian citrus psyllid (ACP), Diaphorina citri, invaded Florida over two decades ago. The need to consistently suppress it became apparent soon after detection and particularly after discovering huanglongbing (HLB) disease, which it spreads. Managing HLB depends strongly on vector control to either reduce disease transmission of healthy trees or reinoculation. Single …
Highlands County Extension agent Lourdes Pérez Cordero recently offered scouting and management suggestions for citrus leafminers (CLM), Asian citrus psyllids (ACP) and rust mites. The suggestions were part of an article in the January issue of Citrus from the Ridge to the Valley, the Central Florida citrus Extension newsletter. CITRUS LEAFMINERS The emergence of spring and summer flush benefits CLM, …
By Lukasz L. Stelinskiand Jawwad A. Qureshi Asian citrus psyllids (ACP) are at the mercy of their host (citrus) for survival. They need flush to lay eggs and for the nymphs to develop. Prior to HLB, the majority of flushing had been fairly predictable and occurred in the early spring and late summer. The occurrence of flush in young trees …
In a Jan. 12 virtual Zoom seminar from Immokalee (dubbed “Zoom’okalee” in the presentation), researcher Ozgur Batuman reviewed old and new approaches to controlling HLB. The seminar was titled “Citrus Disease Trends We Should Heed: HLB, Phytophthora and Leprosis.” Batuman works for the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Southwest Florida Research and Education Center (SWFREC) …
In an open letter to California citrus growers, Jim Gorden, chair of the Citrus Pest & Disease Prevention Committee, emphasized the importance of cooperation of all growers to keep huanglongbing (HLB) at bay. Growers need to work together to coordinate treatments for maximum effectiveness. “As the threat of HLB continues, industry members know that the best way to prevent HLB …
By Michael Rogers January marks the season for resolutions: exercising more, eating well and being more organized. But in the research world, resolutions may not be that simple. I don’t think that University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers could be any more “resolved” in finding ways to fight citrus diseases and ways to improve how …
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 impacts of Asian citrus psyllid (ACP), the vector of huanglongbing (HLB), is part of the annual management …
By Lauren M. Diepenbrock Maintaining a productive citrus grove in Florida takes a lot of effort and innovation these days. So much so that growers’ needs can outpace the timeline of the researchers who support this industry. As such, growers often move forward with promising ideas or tools before researchers can provide useful recommendations toward successfully incorporating these tools. The …
At the recent California Citrus Conference held in Visalia, Monique Rivera, assistant cooperative Extension specialist at University of California Riverside, presented information about management of Asian citrus psyllid (ACP) in organic citrus grown in the San Joaquin Valley. “There is consumer demand that needs to be met for organic citrus,” Rivera said. “So there is a quick transition in the …
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 …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) was recently awarded more than $2.2 million in federal grants for HLB research. The funding came from the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) Emergency Citrus Disease Research and Extension Program. UF/IFAS researchers are also serving in leadership roles in two other NIFA-funded …
What is believed to be the most northern HLB find in Florida was made the first week of November in a backyard Satsuma tree in Tallahassee. A homeowner sent photos of the tree’s symptoms to Leon County Extension horticulture agent Mark Tancig, who collected samples that were confirmed as HLB. “I’ve told the homeowner he should remove it (the tree), …
HLB-tolerant rootstock seeds from the University of Florida (UF) have arrived in Dareton and Bundaberg to be evaluated under Australian conditions. Citrus Australia CEO Nathan Hancock said it’s important that the rootstocks have arrived in Australia well before the Asian citrus psyllid (ACP) and the HLB it spreads. “We need to know if these rootstocks from Florida are going to …
At the 2021 Citrus Expo, entomologist Lukasz Stelinski suggested ways growers can manage HLB-spreading Asian citrus psyllids (ACP) while reducing costs. Some of the University of Florida Institute of Food and Agricultural Sciences entomologist’s key points follow: Psyllid density is related to tree stress; more psyllids lead to higher damage, compromising tree health and yield. Spray for adults at bud …
The low initial U.S. citrus crop forecast for the 2021–22 season points to the need to plant more trees to sustain the country’s citrus industry. The November issue of Citrus Industry magazine features articles that will help growers take care of their young trees. Two articles help answer the question of what to plant. First, University of Florida’s (UF) Ute …
