The use of chemicals for HLB-spreading Asian citrus psyllids (ACP) and other pests has raised several concerns, Jawwad Qureshi reported in a virtual Florida Citrus Growers Institute presentation. Those concerns include pest resistance, costs and diminishing biological control of pests, as well as concerns about health and the environment. Qureshi, a University of Florida Institute of Food and Agricultural Sciences …
University of California Riverside Extension Specialist Monique Rivera said that funding for a new research project to study the Asian citrus psyllid (ACP) has been approved. The project will take a closer look at the phenology of huanglongbing (the citrus disease ACP spreads) and its prevalence in psyllid populations. The scientists will be looking for patterns that will help them …
Ariel Singerman, University of Florida assistant professor, made an online presentation during the recent Agricultural and Applied Economics Association annual meeting. He shared his research on the implementation of area-wide pest management throughout the state of Florida. “Diminishment of pest populations by farmers on their own farm is the most widely used strategy for pest control. However, this is compromised …
The Citrus Pest & Disease Prevention Program, an agency of the California Department of Food and Agriculture (CDFA), has revised the rules governing shipment of citrus within the state. The rules are in place to protect commercial citrus groves from the threat of huanglongbing (HLB) disease. Effective July 31, 2020, bulk citrus fruit may be shipped directly to a packinghouse …
Lukasz Stelinski recently shared integrated pest management strategies for reducing Asian citrus psyllid (ACP) populations to optimize tree health and yield. The University of Florida Institute of Food and Agricultural Sciences professor of entomology and nematology presented the information during the 2020 virtual Florida Citrus Industry Annual Conference. Even with approximately 100 percent of Florida citrus trees infected with huanglongbing …
Managing the Asian citrus psyllid (ACP) that spreads citrus greening disease (HLB) has become a crucial task at the forefront of much research. One management option that has proven to reduce ACP populations while increasing tree growth and yield is particle film. During the 2020 virtual Florida Citrus Industry Annual Conference, University of Florida Institute of Food and Agricultural Sciences …
Funding for Asian citrus psyllid (ACP)/huanglongbing (HLB) programs and the Citrus Pest & Disease Prevention Division (CPDPD), an agency of the California Department of Food and Agriculture (CDFA), were included in the 2020-2021 California budget. Gov. Gavin Newsom signed the budget on June 29. The CPDPD, known also as the Citrus Division, utilizes state, federal and grower-generated funds to prevent …
The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) recently released an annual report titled “Plant Protection and Quarantine: Helping U.S. Agriculture Thrive — Across the Country and Around the World.” The document includes updates on efforts to manage citrus diseases. “PPQ (Plant Protection and Quarantine) stands shoulder-to-shoulder with citrus growers to combat citrus canker, huanglongbing (HLB …
The University of California, Riverside (UCR) recently released information regarding a promising new treatment for huanglongbing (HLB) and the Asian citrus psyllid that “effectively kills the bacterium causing the disease with a naturally occurring molecule found in wild citrus relatives.” While this news has exciting potential, UCR and California Department of Food and Agriculture scientists agree that growers should continue …
A book about the Asian citrus psyllid (ACP) and huanglongbing (HLB), edited by Jawwad Qureshi and the late Phil Stansly, was recently published by the Center for Agriculture and Biosciences International (CABI). Qureshi is an entomologist with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS); Stansly was also a UF/IFAS entomologist. The book is Asian Citrus Psyllid: …
An update on lebbeck mealybug, a relatively new pest of Florida citrus, was provided recently by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock. Diepenbrock, who works at the Citrus Research and Education Center, prepared the presentation for the April Florida Citrus Growers Institute, which was canceled due to COVID-19. Lebbeck mealybug was found in …
Although huanglongbing (HLB) disease was detected in Florida citrus in 2005, the HLB bacterium wasn’t found in Texas until 2011, when scientists detected it in Asian citrus psyllids (ACP). The disease wasn’t found in Texas citrus trees until 2012, suggesting that the HLB-spreading psyllids may be used for early detection of the pathogen in newly invaded areas. Factors influencing the spread …
Kirsten Pelz-Stelinski, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor, recently discussed her research on bacteria associated with Asian citrus psyllids. This includes endosymbiotic bacteria that live inside of psyllids as well as the liberibacter that causes citrus greening disease. Her research is looking at how these microorganisms can be targeted inside the psyllid to reduce …
Lukasz Stelinski makes the case that reducing HLB-spreading Asian citrus psyllid (ACP) populations improves tree health — even when trees already have HLB. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist offers several tips about psyllid control in a new presentation available online. Keeping ACP populations down seems to help yield, Stelinski states. His hypothesis is …
A California citrus grower says he has substantially increased water retention and decreased irrigation usage by planting cover crops. Chris Sayer, of Petty Ranch, says he has added about 3 percent organic content to his soil, which has reduced irrigation water usage from 2 acre feet to 1.25 to 1.5 acre feet. Sayer is a fifth-generation Ventura County farmer. He …
The COVID-19 pandemic that reduced food-service sales nationwide took a toll on some Texas citrus growers this season. MARKET DISRUPTION“Schools and restaurants make up a significant percentage of sales for Texas citrus,” said Dale Murden, a grower and president of Texas Citrus Mutual. “Whether it’s fresh or juice, the loss of those markets definitely hurt.” At least in part because of the …
The California Department of Food and Agriculture (CDFA), through its Citrus Pest & Disease Prevention Program, has developed a mobile-friendly, Spanish-language training video. It’s for use by field crew supervisors and farm labor contractors prior to harvest. The new tool trains industry managers and workers, including field crews, with best practices to prevent the spread of the Asian citrus psyllid …
Researchers with several organizations are in the early stages of investigating the use of neuropeptides found in Asian citrus psyllids as the source for biocontrols for HLB disease. The researchers are with the Boyce Thompson Institute (BTI) at Cornell University, the U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) and the University of Washington. The research team is led by …
Although the Asian citrus psyllid (ACP) is found in Arizona at very low levels, the devastating huanglongbing (HLB) disease, also known as citrus greening, is not. John Caravetta, associate director of the Arizona Department of Agriculture (AZDA), discussed successful efforts to control the psyllid and prevent HLB from infecting orchards. Caravetta reported that “AZDA is conducting trapping for ACP in …
A new finding of huanglongbing (HLB) has been reported in a residential citrus tree in the city of San Bernardino, California. This is the first confirmed find of the citrus disease in the city and follows the recent detections of several HLB-positive trees located in Colton, Montclair and Ontario. The California Department of Food and Agriculture (CDFA) is working with …
