Below you'll see everything we could locate for your search of “psyllid”
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 …
Citrus trees grown in Florida continuously undergo various types and levels of stress. Stressors can include severe weather conditions, soil pH, chemicals, pests and diseases. The constant presence of HLB and psyllid infestation adds further stress to the tree, compromising overall tree health. Off-season flowering and prolonged flowering are common responses of trees when undergoing various stress conditions. Off-season and …
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 …
By Nian Wang, Fred Gmitter and Manjul Dutt Nearly all commercially important citrus types — oranges, grapefruits etc. — have originated by mutations that have accumulated over several hundreds to thousands of years, from what once was an original, individual sweet orange tree and a single grapefruit tree. The many different cultivars that we know today are descended from those …
Researchers from Sacramento State and the University of California, Riverside are requesting input from citrus industry members to help examine the economics of Asian citrus psyllid (ACP) and huanglongbing (HLB) management in California citrus groves. The research team is looking for growers, advisors and other citrus industry members in California to provide input on overall knowledge of ACP and HLB, …
Entomologist Lauren Diepenbrock is seeking Florida citrus growers’ help in determining information gaps and future directions for her research on pests. To get that help, she’s asking growers to participate in a survey, which is available here. Diepenbrock, a University of Florida Institute of Food and Agricultural Sciences researcher, would like to have growers take the survey by March 31, …
Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are looking to increase the efficiency of known Asian citrus psyllid (ACP) control techniques by using them together. The pairing should help control populations of the insect that spreads huanglongbing (HLB) disease. Bryony Bonning, UF/IFAS eminent scholar and entomology professor, is leading the research funded by a …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has resumed providing growers with regular flower bud advisories now that the critical time for citrus grove management has begun this season. Tripti Vashisth, UF/IFAS assistant professor, restarted the advisories Nov. 23 and will continue providing them every other week through the spring. The advisories provide critical information about …
By Fernando Alferez, Susmita Gaire, Ute Albrecht, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri It has been nearly three years since the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) started its studies on individual protective covers (IPCs). The objective of this study is to evaluate the feasibility of IPCs as a strategy to prevent HLB infection of …
The November episode of the All In For Citrus podcast covers a multitude of grant-funded research that the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus team both leads and collaborates on. Citrus Research and Education Center Director Michael Rogers begins the podcast with a discussion on research projects UF/IFAS scientists are playing critical roles in collaborative …
By Jawwad Qureshi Young citrus trees produce shoots with feather-stage leaves more frequently, making them highly attractive to the Asian citrus psyllid (ACP). This pest requires young shoots with feather-stage leaves to develop and reproduce. ACP is the pathogen’s primary vector responsible for causing huanglongbing (HLB) disease. Plant infection with HLB at an early age makes it challenging to bring …
By Arnold Schumann, Laura Waldo, Napoleon Mariner and Timothy Ebert According to the U.S. Department of Agriculture (USDA), Florida grapefruit production for the 2019–20 season was only 12 percent of the production recorded in 2003–04, prior to the arrival of huanglongbing (HLB) disease in the state. A major goal of the University of Florida Institute of Food and Agricultural Sciences …
To the surprise and consternation of growers and officials, 74 Asian citrus psyllids (ACP) have been discovered in Kern County, California, since June. Local and state officials are concerned about the recent uptick in trappings and are working to find how extensively the infestation has spread. The trappings have been equally dispersed in residential and commercial citrus. Staff from the …
Citrus growers told Environmental Protection Agency (EPA) officials why they want the insecticide aldicarb registered for use in Florida citrus, and discussed their problems with citrus greening. EPA cancelled the use of Temik, the Bayer brand name for aldicarb, on citrus at the end of 2011. Mike Aerts of the Florida Fruit & Vegetable Association (FFVA) said the Oct. 22 …
As the new Florida citrus season starts, growers have many things on their minds: the low citrus forecast, the threat of potential freezes, and how best to protect both trees and employees. The November issue of Citrus Industry magazine aims to address these concerns. First up is a complete report on the U.S. Department of Agriculture’s initial crop forecast for …
Three teams of scientists from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) recently received nearly $4.5 million in U.S. Department of Agriculture (USDA) funds to study new ways to manage HLB. The funding is part of the $45 million in grants the USDA National Institute of Food and Agriculture’s Emergency Citrus Disease Research and Extension Program …
The U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA-NIFA) recently awarded 12 grants totaling more than $45 million for research to combat HLB. “USDA-NIFA’s Emergency Citrus Disease Research and Extension Program (ECDRE) brings the nation’s top scientists together to tackle this problem,” said Parag Chitnis, NIFA’s acting director. Following are the 12 ECDRE projects funded by USDA-NIFA …
California’s ACP/HLB San Joaquin Valley Task Force reports that an increased number of Asian citrus psyllid (ACP) trap finds have occurred in the southern part of Kern County. The task force made the announcement in an open message to all citrus growers in the San Joaquin Valley. It was published on the Citrus Insider website on Oct. 16. Last month …
Many Florida citrus growers have been using individual protective covers (IPCs) for several years primarily to protect trees from HLB-spreading Asian citrus psyllids (ACP). Smaller but increasing numbers of growers are utilizing the more expensive citrus under protective screen (CUPS) system to protect trees from ACP and HLB. Recently, Fernando Alferez informed growers in a virtual presentation about some other …
Including recent news about a peptide derived from finger limes, researchers have found many compounds over the last several years that could help growers manage or even fend off huanglongbing (HLB) disease. University of Florida Institute of Food and Agricultural Sciences Research Assistant Scientist Choaa El-Mohtar and his team have developed a new way to see how compounds can possibly …
