Below you'll see everything we could locate for your search of “Asian citrus psyllid”
The pros of injecting the antibiotic oxytetracycline (OTC) into citrus tree trunks to combat HLB appear to be numerous, including increased fruit yield, according to scientist Ute Albrecht. On the other hand, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher only discussed one con, but it was a big one. “Trunk injections cause injury, and long-term …
Federal and state officials in late June expanded the areas quarantined for huanglongbing (HLB, also known as citrus greening), caused by Candidatus Liberibacter asiaticus, in California. The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) took the action in cooperation with the California Department of Food and Agriculture (CDFA). APHIS added portions of Los Angeles, Orange, Riverside …
By Lourdes C. Pérez Cordero Management of the Asian citrus psyllid (ACP) in the HLB era is incredibly important. This well-known insect can vector and facilitate the spread of the bacterium associated with HLB disease. Therefore, effective reduction of ACP populations can be beneficial for the citrus industry. But how exactly do we manage this pest? Unfortunately, there is not …
By Christopher Vincent Kaolin particle film is a non-toxic tool to reduce psyllids and increase tree growth. Particle films are nothing more than a suspension of solid particles that make a “film” on the leaves after they dry. They work mostly by reflecting light. Kaolin is the most common type of particle film because the clay is mined directly and …
California’s commercial citrus groves remain free of HLB disease 14 years after Asian citrus psyllids (ACP) were first detected there. The state’s Citrus Pest and Disease Prevention Program (CPDPP) described that as “no small feat” in its recently released 2020-21 annual report. “The past fiscal year presented its fair share of headwinds for citrus-growing operations,” the report stated. “From pandemic-induced …
County and state officials in California have been actively responding to various Asian citrus psyllid (ACP) discoveries in the Central Valley in recent weeks. Kern, Tulare and Fresno counties have all reported an ACP detection over the last month. The Citrus Pest and Disease Prevention Division (CPDPD) has been implementing delimitation protocols and necessary treatment programs. CPDPD Director Victoria Hornbaker …
The California Department of Food and Agriculture (CDFA) recently urged all citrus industry members to be extra vigilant in their Asian citrus psyllid (ACP) mitigation steps and adherence to regulatory practices. The request is in response to ACP detections in the Central Valley over the last few weeks. ACP is the vector of HLB disease. Multiple ACP were detected on …
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 …
Although it was National OJ Day, the Southwest Florida Small Farmers Network held its spring meeting May 4 at a Polk County facility growing citrus for the fresh market. The Story Companies and Dundee Citrus Growers Association (CGA) conducted a tour of Story’s 11-acre citrus under protective screen (CUPS) pod. The Story pod is one of numerous such pods at …
The spread of HLB in Florida citrus groves has forced growers and researchers to try all sorts of practices to fight off the disease’s devastating effects. One of the most successful methods has been planting citrus under protective screen (CUPS). The screen excludes the Asian citrus psyllid (ACP) and keeps HLB out of plantings. CUPS also is a great example …
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, …
By Hailing Jin Research on the effectiveness of a novel stable antimicrobial peptide (SAMP) identified from the Australian finger lime (Microcitrus australasica) to fight huanglongbing (HLB) continues in a multistate initiative involving 1,500 citrus trees. Although the pandemic has impacted the progress of the research, work has steadily continued and expanded. Researchers at the University of California, Riverside and University …
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 …
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 …
By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …
Nabil Killiny, an associate professor of plant pathology for the University of Florida Institute of Food and Agricultural Sciences, has been studying the relationship between the bacterium that causes HLB (Candidatus Liberibacter asiaticus) and its vector the Asian citrus psyllid (ACP). Globally, insect-borne vector pathogens are responsible for more than 700 plant diseases. HLB ranks high among those in terms …
All indications are that the recent widespread use of individual protective covers (IPCs) on young citrus trees in Florida is beneficial, especially for excluding Asian citrus psyllids and the HLB they spread. If there is any downside, it may be that some other pests and diseases are more prevalent under IPCs. In a recent American Society for Horticultural Science webinar, …
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 …
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 Lauren Diepenbrock Insect and mite management is a year-round challenge in Florida citrus. With the warm climate, pests are at the ready as soon as plant resources are available to them. With knowledge of insect and mite biology in relation to tree phenology, plans to protect fruit and maintain productive citrus trees can be developed. MAJOR PESTSPopulations of some …
