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 …
In a press release dated September 14, California Citrus Mutual (CCM) announced that the state’s current navel orange crop is down about 7 million cartons. This is approximately 10 percent of total production and is the second year in a row crop production has fallen. The 2017-18 California Navel Orange Objective Measurement Survey released on September 12 forecasts the 2017-18 …
A new effort is underway in California to further regulate chlorpyrifos. On August 18, the California Department of Pesticide Regulation (DPR) issued a directive for interim mitigation measures to address health risks from the pesticide. This action marks the start of a public and scientific review of DPR’s revised draft risk assessment that could lead to increased restrictions statewide. At …
University of California (UC) scientists at the Lindcove Research and Extension Center (LREC) will soon begin to test the effect of growing citrus under protective screen (CUPS). CUPS is a proposed new method of controlling huanglongbing (HLB), or citrus greening disease, by keeping psyllids, small insects known to spread the disease, away from the trees. The test will evaluate the …
A citrus tree in the city of Riverside tested positive for huanglongbing (HLB) disease. The detection is the first case of HLB found in a major citrus-producing county and the most northern in California. The California Department of Food and Agriculture (CDFA) confirmed the detection of HLB disease in a sample taken from a grapefruit tree located in a Riverside …
California is adding funds to help the fight against HLB. Governor Brown signed the 2017 Budget Act this week, which authorizes $10 million to fight the spread of the invasive Asian citrus psyllid (ACP) insect and the deadly and incurable plant disease it can carry, huanglongbing (HLB). “California Citrus Mutual applauds Governor Brown and members of the California Legislature for …
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, …
San Bernardino County Supervisor James Ramos is asking his constituents to help preserve the citrus industry and protect citrus trees in their area from HLB. In an article he wrote for a community newspaper (The Press-Enterprise), Ramos pointed out that citrus is a staple crop of San Bernardino County and has a rich history that traces as far back as …
The California State Assembly approved a bill that will allow the citrus industry to increase fees to provide funds for activities to protect residential and commercial citrus trees from the Asian citrus psyllid (ACP) and the deadly huanglongbing (HLB) plant disease it can carry. SB 243 by Senator Galgiani (Stockton) allows for an additional $9.6 million in grower assessments to …
Huanglongbing (HLB) was confirmed in a single citrus tree in the city of La Habra in Orange County, California, on April 11, 2017. This new find will result in a new HLB quarantine area, which will link the existing quarantines into a contiguous zone spanning portions of Los Angeles and Orange counties. Additionally, two samples of Asian citrus psyllids (ACP) …
A new tarping regulation for citrus loads was put on hold by the California Department of Food and Agriculture (CDFA). Ag leaders say the industry should still make plans to comply, since the rules will soon be enforced. An enforcement date has not been announced, but could come as soon as April 1. The new regulation, which was supposed to …
The citrus crop forecast, delivered by Mark Hudson of the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service in Washington, D.C., showed a 4 percent drop in Florida oranges and a 2 percent drop in California oranges. In total, the U.S. all-orange forecast for the 2016-2017 season dropped 3 percent from last month and is down 13 percent from …
California recently passed a state law designed to combat the spread of an Asian citrus pest. All citrus loads transported through California now must be covered, no matter where it’s coming from or where it’s headed.

Asian citrus psyllids are detected sporadically in the San Joaquin Valley — home to most California oranges and mandarins — and are endemic in Southern California lemon country. But as far as anyone knows, the pests that spread HLB in Florida and Texas have not spread the disease into California’s commercial citrus groves. California HLB detections have been limited to 17 …
The Minor Crop Farmer Alliance (MCFA) recently requested that a U.S. Department of Agriculture Reorganization Plan not adversely impact the Pesticide Data Program (PDP) administered by the Agricultural Marketing Service. In a letter to Agriculture Secretary Brooke Rollins, the alliance called the PDP “a relatively small but exceptionally critical program upon which the agriculture community heavily depends.” The letter stated …
Researchers from the U.S. Department of Agriculture-Agricultural Research Service (USDA/ARS) are opening new markets for America’s fruit growers. In Hawaii, Lisbon lemons and Persian or Tahiti limes, both commercially popular cultivars, are new crops recently planted on the rich-soil island of Maui. Currently, the fruit is being sold locally, but harvest volumes may eventually surpass local demand. Export from Hawaii …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP Growing up in Polk County, Emily Worbington saw the groves disappearing. She passed more and more rooftops as she drove around Auburndale.

A new tool has allowed researchers probe the metabolic processes occurring within the leaves, stems and roots of clementine citrus trees. The goal is to improve the yields, flavor and nutritional value of citrus and non-citrus crops. To build the tool, the team — led by the University of California San Diego (UC San Diego) researchers — focused on the …
A recent article by the São Paulo Research Foundation explains how a potent compound might aid in controlling the Asian citrus psyllid, the vector of citrus greening disease. In São Paulo, greening is managed in part by controlling the psyllid. In an attempt to manipulate psyllid behavior, a team of scientists discovered α-copaene, a molecule present in large quantities in …
Texas A&M AgriLife Research is launching a multi-institutional study to develop and evaluate systems that deliver treatments to HLB-affected trees. The principal investigator is Kranthi Mandadi, plant molecular biologist at the Texas A&M AgriLife Research and Extension Center at Weslaco and professor in the Texas A&M Department of Plant Pathology and Microbiology. The three-year, $1.1 million project is supported by the Emergency Citrus Disease Research …
