The citrus leafminer is a small, hard-to-detect pest that hides during the day and comes out at night to lay its eggs. Though this pest is small, it’s been known to cause severe damage to FL citrus crops. Having a broad-spectrum insecticide at your fingertips could go a long way in protecting your crops. While the citrus leafminer remains a …
The damage that HLB has inflicted on Florida citrus groves and production over the past 18 years should serve as a warning for California producers, California’s Citrus Pest & Disease Prevention Program (CPDPP) stated recently. CPDPP noted that with HLB detected in thousands of California residential trees, it’s important for commercial growers to take steps to prevent the disease. According …
There has been much focus on the benefits of applications of plant growth regulators like gibberellic acid and 2,4-D, and more recently oxytetracycline hydrochloride to improve the health of citrus trees infected with HLB. Silicon also has been highlighted for its potential benefits to citrus. Mohammad Adnan Shahid, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, …
The California Department of Food and Agriculture’s (CDFA) Asian citrus psyllid (ACP) quarantine program now requires all harvesters/farm labor contractors (FLCs) to have valid compliance agreements to harvest citrus groves. An FLC is defined as any person or establishment that employs people to perform work related to grove management and/or harvesting commercial citrus fruit. The requirement was announced by CDFA’s …
Kirsten Pelz-Stelinski will become director of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Mid-Florida Research and Education Center (MREC) in Apopka on Aug. 1. She is currently an entomology professor and associate center director of the UF/IFAS Citrus Research and Education Center (CREC) in Lake Alfred. Pelz-Stelinski will lead faculty, staff and students at the MREC. …
Lukasz Stelinski for years has promoted saving money on HLB control by spraying for Asian citrus psyllids (ACP) only when their populations reach a certain threshold. The University of Florida Institute of Food and Agricultural Sciences professor still promotes that concept, but with a slightly new twist. TRUNK INJECTION SHOWING PROMISEIn a virtual seminar on April 25, Stelinski advised growers …
By Jawwad Qureshi A wide range of pests colonize citrus crops. Most of these species target tree canopies, and a few feed on the roots. Damage is either direct through feeding on the plant tissues or it can be twofold if the pest is also responsible for transmitting the pathogens of a disease or making conditions favorable for the disease …
The Citrus Research and Development Foundation (CRDF) board of directors convened its March meeting with a busy agenda, addressing fast-moving current events. Discussion focused on newly approved oxytetracycline hydrochloride (OTC-HCl) trunk-injection products currently being applied in groves. The board funded a project to measure the impact of OTC-HCI applications on the Asian citrus psyllid (ACP). Specifically, the study will determine …
By Davie Kadyampakeni, Samuel Kwakye, Hossein Ghoveisi, Lauren Diepenbrock and Jawwad Qureshi Deficit irrigation practices can reduce water and energy costs, thus potentially increasing water-use efficiency and water savings in citrus production. Irrigation management through deficit applications, if timed at periods of reduced water demand, could help trigger increased root water and nutrient uptake while synchronizing citrus flush patterns. These …
Foliar sprays of insecticides timed to citrus flushing provided a significant reduction in Asian citrus psyllid (ACP) populations compared to standard grower practices, researcher Jawwad Qureshi reported. Timing sprays to flushing also led to a reduction in sprays, the University of Florida Institute of Food and Agricultural Sciences associate professor of entomology said in a virtual presentation on Feb. 22. …
California officials have confirmed the presence of HLB-spreading Asian citrus psyllids in a residential area east of Sonoma. The confirmation came following analysis of a survey trap set by the Sonoma County Department of Agriculture. The county department is coordinating with the California Department of Food and Agriculture (CDFA) in responding to the pest’s presence in Sonoma Valley. “Discovery of …
Australia’s Hort Innovation has announced an $8.7 million investment to trial tree immunizations that protect Australia’s horticulture industries against the deadly huanglongbing (HLB) and Xylella diseases (including citrus variegated chlorosis). Hort Innovation is a grower-owned, not-for-profit research and development corporation for Australia’s horticulture industry. Hort Innovation Chief Executive Brett Fifield said the investment aims to safeguard key Australian horticulture industries by …
When commercial citrus acreage started migrating north some years ago, the big question was: To what extent would Asian citrus psyllids (ACP) and HLB migrate with the crop? With citrus getting well established in South Georgia, the pest and disease are there, but not yet at devastating levels like in Florida. Johnathan Oliver, an assistant professor of fruit pathology with …
“To some extent, every citrus variety has suffered from cold damage” due to the five-night freeze event that occurred in the cold-hardy citrus region Dec. 24–28. That report comes from Jake Price, Lowndes County Extension coordinator for University of Georgia Extension. “The site of our citrus research plots in Valdosta reached a low of 16 degrees, which is the lowest …
By Lukasz L. Stelinski, Lauren Diepenbrock and Larry Duncan Given the focus on HLB in citrus management for more than a decade, important additional pests of citrus have sometimes not received the attention they may deserve. Trees with HLB are weakened and prone to succumb to the effects of the disease when challenged by secondary affliction(s), including infestation by diaprepes …
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) will hold a workshop on citrus insect, mite and nematode management Jan. 19 at the Citrus Research and Education Center in Lake Alfred. The workshop will run from 9 a.m. to 3 p.m. Presentations will be made by UF/IFAS faculty members. UF/IFAS pointed out that pest management in citrus …
Individual protective covers (IPCs) do an excellent job keeping HLB-spreading Asian citrus psyllids (ACP) out of young citrus trees, showing a 99.6% reduction in ACP compared to control trees. But they don’t provide “one and done” pest control, according to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock. In fact, IPCs “create a perfect environment …
By Lauren Diepenbrock Pest management is an ongoing effort in Florida citrus. Taking advantage of pest life cycles has been shown to be an effective tool for reducing populations of target pests. For many citrus growers, managing impacts of the Asian citrus psyllid (ACP), the vector of huanglongbing (HLB), is part of the annual management plan. As we enter the …
California’s Citrus Pest and Disease Prevention Program (CPDPP) has developed a guide, Response for a Confirmed Huanglongbing Positive Detection in a Commercial Grove, to prepare growers for a finding of the disease. The guide is intended to educate growers about the California Department of Food and Agriculture’s (CDFA) huanglongbing action plan. The devastating citrus disease spread by the Asian citrus …
An ongoing study in coastal Southern California citrus groves has found that just over 3.5% of Asian citrus psyllids (ACP) tested are carrying the bacterium that can cause HLB. ACP is the insect vector of HLB. Thus far, 138 of 3,000 adult ACP collected from 15 commercial citrus sites had some level of the bacterium present. The results were reported …
