This article is brought to you by the William & Mary Law School Scholarship Repository. https://scholarship.law.wm.edu/wmelpr SAVING THE ORANGE: HOW TO FIGHT CITRUS GREENING DISEASE (AND IT’S NOT THROUGH GENETIC ENGINEERING) EVAN FEELY* INTRODUCTION The orange is dying. With Florida’s citrus industry already suffer- ing from the growing skepticism of an increasingly health-conscious American public as to orange juice’s benefits,1 the emergence of citrus greening disease over the past two decades has left the orange’s long-term future very much in doubt.2 A devastating virus first documented in China roughly one hundred years ago, citrus greening disease (or “HLB”), has only migrated to Florida in the past twenty years, but has quickly made up for lost time.3 Primarily transmitted by an insect known as the Asian citrus psyllid (“ACP”), the disease has devastated Florida growers in recent years, wiping out entire groves and significantly affecting trees’ overall yield.4 This past year, Florida growers experienced their least productive harvest in forty years, and current estimates of next year’s yield are equally dismal.5 * J.D. -
Kettleman City, Kings County Please Read Immediately
CALIFORNIA DEPARTMENT OF FOOD AND AGRICULTURE OFFICIAL NOTICE FOR CITY OF KETTLEMAN CITY, KINGS COUNTY PLEASE READ IMMEDIATELY THE NOTICE OF TREATMENT FOR THE ASIAN CITRUS PSYLLID On September 18, 2020 the California Department of Food and Agriculture (CDFA) confirmed the presence of Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, a harmful exotic pest in the city of Kettleman City, Kings County. This detection indicate that a breeding population exists in the area. The devastating citrus disease Huanglongbing (HLB) is spread by the feeding action of ACP. The ACP infestation is sufficiently isolated and localized to be amenable to the CDFA’s ACP treatment work plan. A Program Environmental Impact Report (PEIR) has been certified which analyzes the ACP treatment program in accordance with Public Resources Code, Sections 21000 et seq. The PEIR is available at http://www.cdfa.ca.gov/plant/peir/. The treatment activities described below are consistent with the PEIR. In accordance with integrated pest management principles, CDFA has evaluated possible treatment methods and determined that there are no physical, cultural, or biological control methods available to eliminate the ACP from this area. Notice of Treatment is valid until September 18, 2021, which is the amount of time necessary to determine that the treatment was successful. The treatment plan for the ACP infestation will be implemented within a 50-meter radius of each detection site, as follows: • Tempo® SC Ultra (cyfluthrin), a contact insecticide for controlling the adults and nymphs of ACP, will be applied from the ground using hydraulic spray equipment to the foliage of host plants; and • Merit® 2F or CoreTect™ (imidacloprid), a systemic insecticide for controlling the immature life stages of ACP, will be applied to the soil underneath host plants. -

Cinnamon Kumquats

Cinnamon Kumquats “How about a kumquat, my little chickadee?” (W.C. Fields, My Little Chickadee,1940) Say what? Yes, I said kumquats. Those adorable little kumquats. You know, those “things” that you have been so curious about. Another idea for using citrus that is not a marmalade. Vive la différence! That said, a kumquat marmalade is nothing short of marvelous. Honestly. “A kumquat is not an orange though it wants to be one, especially when they’re around other kumquats. (W.C. Fields, It’s A Gift, 1934) Kumquats are native to China, and their name comes from the Cantonese kam kwat, which means "golden orange." They are a symbol of prosperity and a traditional gift at Lunar New Year. Unlike other citrus, kumquats are eaten whole, including the skin. They have a tart-bitter-sweet taste that is boldly refreshing. Ya gotta try one. Really. Just pop one in your mouth and go for it. Fresh kumquats are wonderful in salads and in savory dishes. They are also great in chutneys and relishes. We canned them in a sweet cinnamon syrup. They can then be eaten right out of the jar like candy or used in desserts such as pound cakes or cheesecakes. The syrup is wonderful for drizzles, too. Savory ideas: use them in salads (use the syrup in your dressing!), they would be perfect with ham, maybe as a glaze for chicken wings (I would add some hot sauce, too). -
Tropical Horticulture: Lecture 32 1
Tropical Horticulture: Lecture 32 Lecture 32 Citrus Citrus: Citrus spp., Rutaceae Citrus are subtropical, evergreen plants originating in southeast Asia and the Malay archipelago but the precise origins are obscure. There are about 1600 species in the subfamily Aurantioideae. The tribe Citreae has 13 genera, most of which are graft and cross compatible with the genus Citrus. There are some tropical species (pomelo). All Citrus combined are the most important fruit crop next to grape. 1 Tropical Horticulture: Lecture 32 The common features are a superior ovary on a raised disc, transparent (pellucid) dots on leaves, and the presence of aromatic oils in leaves and fruits. Citrus has increased in importance in the United States with the development of frozen concentrate which is much superior to canned citrus juice. Per-capita consumption in the US is extremely high. Citrus mitis (calamondin), a miniature orange, is widely grown as an ornamental house pot plant. History Citrus is first mentioned in Chinese literature in 2200 BCE. First citrus in Europe seems to have been the citron, a fruit which has religious significance in Jewish festivals. Mentioned in 310 BCE by Theophrastus. Lemons and limes and sour orange may have been mutations of the citron. The Romans grew sour orange and lemons in 50–100 CE; the first mention of sweet orange in Europe was made in 1400. Columbus brought citrus on his second voyage in 1493 and the first plantation started in Haiti. In 1565 the first citrus was brought to the US in Saint Augustine. 2 Tropical Horticulture: Lecture 32 Taxonomy Citrus classification based on morphology of mature fruit (e.g. -
Cooperatives in the U.S.-Citrus Industry
Agriculture Cooperatives in the Rural Business and Cooperative Development U.S.-Citrus Industry Service RBCDS Research Report 137 Abstract Cooperatives in the U.S. Citrus Industry James A. Jacobs Agricultural Economist U.S. Department of Agriculture Rural Business and Cooperative Development Service Citrus is one of the leading fruit crops produced in the United States. Cooperatives play an important role in the handling and marketing of both fresh and processed citrus products. This report examines the development and posi- tion of cooperatives in the citrus industry, their functions and operating prac- tices, and the impact of changes in production practices and industry structure on cooperatives. Cooperatives range from small, local fresh packinghouse associations to large cooperative federations with comprehensive marketing and sales pro- grams in both fresh and processed markets. Cooperatives are among the lead- ing marketers in all producing areas, and are the dominant marketing organiza- tion in California and Arizona. Citrus cooperatives use the pooling method to market and allocate returns. This cooperative practice of averaging price and sharing risk is commonly used by some private citrus firms as well, reflecting the inherent volatility of citrus production.

RBCDS Research Report 137 December 1994 Preface This report describes the position and functions of cooperatives in the U.S. citrus industry. It is the first known detailed examination of its kind on citrus cooperative activities and operating practices. The report is intended as a reference for cooperative managers and mem- bers, professional advisors, and anyone involved in professional activities or research in the citrus industry. -

Italian Grapes
Sicilian Red Oranges (Citrus sinensis) Sicilian Red Oranges Citrus fruits have been cultivated in Italy since ancient times. In Sicily, the “blood” orange gained its nickname because of its ruby flesh that contains the red pigment, anthocyanin, a strong antioxidant. Today, blood oranges are considered the hallmark of Sicilian fruit. Three blood orange varieties, Tarocco, Moro and Sanguinello, can be traced to the hilly areas and plains surrounding the Mt. Etna volcano in Sicily. Temperatures in this region range from intense daylight to frigid temperatures at night. It also has other variables, including modest rainfall and rich soil. The combination of these factors results in a Sicilian Red orange that has incomparable sweetness and distinguishable color. Sicily combines the juiciness of the Florida oranges with the appearance of the Californian oranges. On average, Sicilian blood oranges contain at least 35-percent juice, as compared to its California counterpart which contain 20-percent. The fruit is easy to peel, and most varieties are seedless. The Sicilian Red orange is clearly connected to it natural Mediterranean environment, resulting in fruit with superb flavor that cannot be replicated. These factors position Sicily as the largest producer in the world. It is also why the European Union recognizes the Eastern Sicily area as a Protected Geographical indication, Arancia Rossa di Sicilia, for cultivating pure Tarocco, Moro and Sanguinello varieties. Sicilian Red Oranges Varieties Moro: The Moro variety is believed to have originated at the beginning of the 19th century in the citrus-growing area around Lentini (in the Province of Siracusa in Sicily) as a bud mutation of the “Sanguigno.” Moro are “full-blood” oranges, meaning that the flesh ranges from orange veined with ruby coloration, to vermilion, to vivid crimson and to nearly black. -
