By Angela Chuang and Lauren Diepenbrock While many arthropod predator and pollinator activities benefit crop quality and yields, traditional farming environments may not be ideal habitats to support their survival year-round. For example, wild bees or flies that pollinate citrus may need other sources of nectar and pollen when citrus is not flowering. Planting wildflowers near crop fields to improve …
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 …
Past management, a perennial problem for citrus growers, is the primary focus of the January issue of Citrus Industry magazine. An old pest is posing new concerns for Florida growers. The recent resurgence of diaprepes root weevil is the subject of the cover story by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers Lukasz Stelinski, Lauren Diepenbrock …
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 …
High yields of HLB-free fruit can hypothetically be sustainably produced in citrus under protective screen (CUPS), Arnold Schumann said at a Dec. 14 field day at the Citrus Research and Education Center (CREC). He backed that up with data showing high yields from Ray Ruby grapefruit planted at high densities and fertigated in CUPS. Trees in his CUPS facility are …
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 …
In the search for ways to survive citrus greening, some growers have chosen the citrus under protective screen (CUPS) system as their solution. While CUPS can be costly to construct, it has proven to effectively prevent the deadly disease. But some have asked if the structures would hold up in extreme weather and adequately protect the trees. Hurricane Ian helped …
By Mongi Zekri For maximum efficiency of a grove, it is essential that every location is occupied by a tree and that every tree is healthy. Prompt replacement of dead and declining trees means higher average long-term returns from the grove. If the declining trees remain in the grove, they keep getting weaker and yield less fruit each year. Therefore, …
Regular flower bud advisories from the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) were restarted Nov. 21 and will be provided every other week through early spring. Associate Professor Tripti Vashisth provides the advisories. The advisories provide critical information about the intensity and time of citrus blooms. Growers use this information to determine when to spray for …
By Mongi Zekri Pruning is an important grove practice that increases sunlight penetration within the tree canopy. Sunlight enhances flowering, fruit quality and color development. Sunlight also allows foliage to dry quickly after a rain shower, which reduces problems of fungal diseases. Pruning trees can improve fruit quality and increase fruit size. However, tree response to pruning depends on scion …
The focus of citrus breeding at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) differs for fruit produced for the juice market vs. fruit for the fresh market. Citrus breeder Jude Grosser, a UF/IFAS professor of plant cell genetics, spoke during the Cold-Hardy Citrus Field Day at the North Florida Research and Education Center in Quincy on …
Seven entities recently received $21.7 million to conduct research into combating and preventing HLB at the farm level. The funding is from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA NIFA) Emergency Citrus Disease Research and Extension program. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) received the majority of the funding, more …
By Danielle Leal During a recent trip to Washington, D.C., California Citrus Mutual (CCM) representatives visited with the U.S. Department of Agriculture and members of Congress to outline several citrus industry priorities and secure funding for research. CCM President and Chief Executive Officer Casey Creamer announced during the 2022 California Citrus Conference that the Citrus Research Board received funding from …
While irrigation and technology were meant to be the focus of the November issue of Citrus Industry, the aftermath of Hurricane Ian, combined with the low initial crop forecast that does not even account for the storm’s damage, proved to be the much bigger story. Editor-in-Chief Frank Giles provides early details on the hurricane’s damage to Florida’s citrus industry and …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) multi-county citrus Extension agent Ajia Paolillo summarized suggestions for controlling pest pressure after Hurricane Ian in a recent Extension newsletter. Along with horticultural practices and disease control, growers should be monitoring for pests in their groves post-hurricane. UF/IFAS entomologist Lauren Diepenbrock provided some suggested practices for keeping pest pressure as …
By Danielle Leal The 2023 California Citrus Conference in Visalia proved collaboration is pivotal when tackling industry issues. The conference, hosted by California’s Citrus Research Board, had a lineup of industry leaders, researchers and others who updated growers on California’s citrus industry. Casey Creamer, president and chief executive officer of California Citrus Mutual, spoke on strengthening the connection between research …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) faculty recommend actions citrus growers can take to prevent further damage to root systems and future fruit drop following Hurricane Ian. DEAL WITH PHYTOPHTHORAIf standing water has occurred in groves with phytophthora problems, growers should evaluate for root damage and treat accordingly. Floodwaters resulting from heavy rains can severely impact …
The severe impacts of recent storms are layered on top of the complex set of challenges already facing U.S. citrus growers—especially in Florida. From high input costs to domestic supply shortages, the unmatched devastation caused by citrus greening disease, and now the recovery efforts needed post-hurricane, growers need holistic solutions–and they need them fast. The good news is that breakthrough …
Imidacloprid has been a key tool in the fight against HLB. The insecticide is particularly important in protecting young trees from the Asian citrus psyllid, the vector of HLB disease. Admire Pro SLN is currently labeled to treat young citrus trees for HLB. But a fire at the Bayer manufacturing facility where the product is made has disrupted supplies. During …
