By Jawwad Qureshi, Lukasz Stelinski and Fernando Alferez Management of huanglongbing (HLB) has focused on reducing the vector Asian citrus psyllid (ACP) and improving tree health, thus requiring a multi-pronged approach. Several elements of an HLB management system are either available or under current investigation. Maintenance of clean nursery stock, vector management and tree nutrition are widely implemented, while incorporation …
The U.S. Environmental Protection Agency (EPA) has approved an emergency authorization requested by California Citrus Mutual (CCM) to use Evergreen Pro 60-6 (EPA Reg. No. 1021-1770). It was temporarily approved as a post-harvest treatment option for all citrus in California to prevent the spread of Asian citrus psyllids, the vector for huanglongbing. CCM had requested that citrus growers be allowed to use …
By Arnold Schumann, Timothy Ebert, Laura Waldo, Danny Holmes, Napoleon Mariner, Gary Test, Chris Oswalt, Rhuanito Ferrarezi and Ricardo Lesmes Two studies with citrus under protective screen (CUPS) were established at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center (CREC) and Indian River Research and Education Center (IRREC) in 2013–14. The goal …
By Len Wilcox Research into high-density citrus plantings is gaining momentum at both ends of the country. In a study funded by the California Citrus Research Board, scientists are evaluating the consumption of water and other inputs used by high-density dwarf citrus trees. The scientists want to determine costs while the trees are maintaining high production levels. In Florida, researchers …
At the center of the August issue of Citrus Industry magazine is the Citrus Expo show guide. Readers will find everything they need to know about Florida’s leading agricultural event. This year, Citrus Expo is expanding its reach to include vegetable and specialty crop growers. The Citrus Expo seminar and trade show is August 15–16 at the Lee Civic Center …
By Lukasz L. Stelinski, Jawwad A. Qureshi and Philip A. Stansly Florida citrus is host to four main groups of mites categorized by differences in lineage and morphology. However, only rust mites, spider mites and broad mites historically cause economic damage to commercially grown citrus in the state. The fourth group, referred to as false spider mites, are vectors elsewhere …
A California Superior Court judge has ordered the state’s Department of Food and Agriculture (CDFA) to temporarily stop spraying pesticides for agricultural pest control. The judge decided in favor of a lawsuit filed by 11 environmental activist groups and the city of Berkeley. Private citizens will still be able to use chemical insecticides on their property, but the order requires …
By Jawwad A. Qureshi, Philip A. Stansly and Lukasz L. Stelinski Pest management has always been important for citrus production in Florida. It has become even more critical following invasion of the Asian citrus psyllid (ACP) and citrus leafminer (CLM), due to their association with huanglongbing (HLB or citrus greening) and canker diseases, respectively. ACP and CLM develop and reproduce …
Integrated pest management (IPM) strategies and copper are both good control measures for common citrus foliar fungal diseases, as well as for citrus canker. So says University of Florida Institute of Food and Agricultural Sciences plant pathologist Ozgur Batuman. Batuman summarizes information he presented at a fall field day and seminar attended by about 60 people at the Southwest Florida …
Chlorpyrifos is being targeted again by environmental agencies. According to a press release from California Citrus Mutual (CCM), the California Environmental Protection Agency announced in mid-August that both California Department of Pesticide Regulation (DPR) and the Office of Environmental Health Hazard Assessment are pursuing new restrictions on chlorpyrifos. CCM says that chlorpyrifos is one of the most important and widely …
The California Citrus Research Board (CRB) hosted live Asian citrus psyllid (ACP) fogging demonstrations in April. The purpose was to show the viability of controlling the spread of ACP by fogging shipments of citrus on the truck, as close to the harvested field as possible. Spencer Walse, CRB research scientist specializing in chemical applications in agriculture, carried out the demonstrations. He is based at …
As in previous years, orange shipments to Korea must be free of Fuller rose beetle (FRB) and California red scale (CRS). Growers desiring to qualify oranges for export to South Korea must comply with the FRB protocol during the 2017-2018 shipping season. Growers are required to implement the following measures for FRB control on oranges: 1. Skirt-prune trees to prevent …
Sponsored Content A Florida company may hold the key to protecting the world’s young citrus plantings until a permanent solution for the devastating citrus greening disease (HLB) can be found. Widespread devastation from citrus greening has caused billions of dollars in lost revenue and killed over 100 million citrus trees worldwide. Although there appears to be no end in sight, …
By Len Wilcox Effective January 1, California updated its pesticide worker safety standards to comply with the new federal Worker Protection Standard. The update addressed re-entry to application exclusion zones, fieldworker training, new posting requirements, eyewash equipment and hazard communication. It also made other refinements to the state’s existing standards. Bill Griffin, pesticide supervisor for the Fresno County Agriculture Commissioner, …
Over industry objections, the California Department of Pesticide Regulation (DPR) is continuing its effort to create new regulations for the use of agricultural pesticides near school sites and licensed child day care facilities. A recently published revision included changes made due to input received during public review. This revision did not go far enough to satisfy objections. After reviewing the …
By Larry Duncan Citrus growers are recognized as early adopters of practices that enhance the biological control of arthropod pests. For more than a century, tactics such as the exploration and importation of predators and parasitoids or the reduced use of insecticides that disrupt biological control were increasingly employed against pests in the tree canopy. Beginning in the early 1990s, …
Pest management is the theme of the February 2017 issue of Citrus Industry magazine. University of Florida entomologist Phil Stansly is featured in the cover story. Stansly has been helping growers control Asian citrus psyllids (ACP) since HLB first appeared in Florida. Learn more about his history of HLB work and what he is currently focusing on in the profile …
By Sara LaJeunesse, Penn State University A chemical that is thought to be safe and is, therefore, widely used on crops — such as almonds, wine grapes and tree fruits — to boost the performance of pesticides, makes honey bee larvae significantly more susceptible to a deadly virus, according to researchers at Penn State and the U.S. Department of Agriculture. …
Ed Pines’ solution to citrus greening is to grow fruit in a citrus undercover production system. By Catalina Pines “It’s said that necessity is the mother of all invention, and today I toured one way the citrus industry is fighting back against greening,” said Florida Commissioner of Agriculture Adam Putnam on Twitter after touring Precision Citrus on September 23. In …
By Arnold Schumann, Laura Waldo and Alan Wright Research for producing huanglongbing (HLB)-free fresh Florida citrus with covered production systems began at the University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center in 2013 and at the Citrus Research and Education Center (CREC) in 2014. These citrus undercover production systems (CUPS) evolved from the …
