POPULAR CITRUS GUIDE If you’re considering planting a citrus tree on your property, be sure to get your plant from a reputable, licensed nursery in your area – and recognize you need to manage pests and diseases on your tree throughout its lifetime. Inspect for the Asian citrus psyllid and the deadly plant disease Huanglongbing (HLB) monthly or whenever watering, spraying or pruning trees. Pest and disease management is critical to protect not just your own tree, but also your neighbors’ trees and the state’s citrus.

Cultivar and Rootstock Research for the Arizona Citrus Industry
Supporting the University of Arizona Citrus Variety Collection 20171 Glenn C. Wright2 2School of Plant Sciences, University of Arizona, Yuma Agriculture Center, Yuma, AZ Introduction The 8-acre citrus variety collection at the Yuma Agriculture Center is the most comprehensive collection of citrus within Arizona, containing about 110 selections. The collection was propagated in 1993 and is found in Block 17. The collection has value because it serves as a resource for research, teaching and extension. From 1993 until 2008, data was taken from the lemon selections within the collection. We use fruit, leaves and flowers from the collection to teach students of the Citrus and Date palm production course that I teach through UA-Yuma. A part of one laboratory session takes place within the collection. We also use the collection to teach Master Gardeners, and the we lead tours through the collection for Master Gardeners and other interested parties. We use fruit from the collection for displays and tasting for community events. Now, the trees are aging, and we are in the process of re-propagating the collection into a 3-acre parcel in Block 18 at the Center, but the task is not yet finished. Some of those new trees are planted in the new blocks while others are growing in a field nursery and others have yet to be budded. About one acre of the new collection is in the ground. Few of the new trees have fruit. The University has borne the cost of maintaining the collection for the past 23 years, but those costs can no longer be absorbed.

Reaction of Tangerines Genotypes to Elsinoe Fawcettiiunder
Reaction of tangerines genotypes to Elsinoe fawcettii under natural infection conditions Crop Breeding and Applied Biotechnology 11: 77-81, 2011 Brazilian Society of Plant Breeding. Printed in Brazil Reaction of tangerines genotypes to Elsinoe fawcettii under natural infection conditions Marcelo Claro de Souza1*, Eduardo Sanches Stuchi2 and Antonio de Goes3 Received 11 February 2010 Accepted 30 September 2010 ABSTRACT - A citrus scab disease, caused by Elsinoe fawcettii, is currently found in all citrus areas throughout Brazil. That being, given the importance of this casual agent, the behavior of tangerines and hybrids influenced by this pathogen was evaluated under natural infection conditions. This study was performed with plants around 15 years old without irrigation; 100 fruits of three plants were collected during harvest season, using a grade scale varying from 0 (absence of symptoms) to 6 (severe symptoms) the level of disease severity was determined. Among the cultivars, citrus scab resistance was observed in Citrus deliciosa, C. tangerina, C. nobilis; a mandarin hybrid (C. nobilis x C. deliciosa) and a satsuma hybrid (C. unshiu x C. sinensis). Among the other genotypes, symptoms were observed with levels of severity ranging from 1 to 3, indicating moderate resistance. Key words: Citrus scab, citrus crop, resistant varieties. INTRODUCTION In Brazil, E. fawcettii is responsible for citrus scab. The disease is widespread in many humid, citrus-cultivating In many citrus production areas around the world, areas around the world and decreases fruit values on the Elsinoe fawcettii is one of the main fungi diseases found. fresh-fruit market (Feichtenberger et al. 1986).

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.

Crop Profile for Citrus (Minor) Lime, Pummelo, and Kumquat in Florida
Crop Profile for Citrus (Minor) Lime, Pummelo, and Kumquat in Florida Prepared: November, 2001 General Production Information ● Lime in this crop profile refers to the 'Tahiti' lime (Citrus latifolia). Pest management practices of other members of the Rutaceae such as Key lime (Citrus aurantifolia), pummelo (Citrus grandis), and kumquat (Fortunella sp.) may also be described, since survey questionnaires grouped these four tropical fruits together. All of these species of citrus are grown for the fresh market. ● The 1997-1998 average yield of limes in Florida was 14,344 pounds per acre. At a price of $5.02 per box, the Florida crop (440,000 boxes) was worth approximately $2.21 million (1). ● In 2000-2001, 1,171 acres in Florida produced 22 million pounds of 'Tahiti' lime. This is a 58 percent decrease from the previous year, when 53 million pounds were recorded (2,3). ● As of the end of 2000, there has been a 63 percent reduction in lime acreage since 1996 (bearing acreage of 3,168 acres). Except for 20 acres, all of the lime production is located in Miami-Dade County. Consequently, ninety-eight percent of 'Tahiti' lime production occurs in this county (3). ● Florida was ranked first in the United States in lime production. No other states were listed as leading lime-producers (1). ● Reductions in lime acreage have occurred due to Hurricane Andrew and citrus canker. Bearing acreage before Andrew was approximately 6,000 acres, which dropped drastically to 1,668 acres after this event (4). An estimated 290,000 lime trees (2,800 acres) have been lost to citrus canker in the 2000-2001 period (2).

About Limes by George Geary CCP
All About Limes By George Geary CCP Lime History In the eighteenth century, Scottish naval surgeon Sir James Lind learned by his observation of long-haul sailors that citrus fruits conquered the dreaded scurvy (lack of Vitamin C) which had divested the ranks of the British navy more than any enemy. Between 1795 and 1815, some 1.6 million gallons of lime Juice drastically reduced the mortality rate of seamen. Along with their daily ration of rum, British sailors were required to consume a daily ration of lime Juice; hence British seamen became known as limeys. Since Britain was often at war with Mediterranean countries that exported lemons, limes imported cheaply from the English colony of Jamaica were substituted as the citrus of choice. Key Lime (also known as Mexican Lime and West Indies Lime) Cultivated for thousands of years in the Indo-Malayan region, this variety has long been treasured for its fruit and decorative foliage. The Key lime made its way to North Africa and the Near East via Arabian traders, and then carried on to Palestine and Mediterranean Europe by the Crusaders. Columbus is credited with bringing the Key lime to Haiti, where Spanish settlers to Florida carried it on. It flourished in South Florida, particularly the Florida Keys, hence the current common name of Key lime. Due to hurricane-depleted soils, locals switched from pineapple commercial crops to limes in 1906, and business boomed until a hurricane once again reared and wiped out the lime groves, never to be restored. Today, most Key limes come from Mexico.
