MEDFLY The Medfly quarantine was removed in the Upland area of San Bernardino and Los …
Preliminary data from an Australian research project suggest Chinese rootstocks No. 24 and 85-24 are having a dwarfing effect on citrus tree growth and will be candidates for future high-density cropping systems. Citrus Australia reported that those rootstocks have strong potential in heavy soils, and that results on deep sandy loam soil are also very encouraging. Tahir Khurshid from the …
By Davie Kadyampakeni Nutrients are needed for optimal citrus tree growth, fruit yields and juice quality. Any nutrient deficiencies could result in low yields and decreased revenue. Make sure citrus trees receive adequate macronutrients and micronutrients at all times. Macronutrients are those nutrients needed in large quantities to influence yield, growth and fruit quality. Macronutrients are further divided into two …
By Jude Grosser, Manjul Dutt and Fred Gmitter Exploiting citrus genetic diversity is the key to defeating HLB. Plant species have survived for millennia with evolving, hostile pathogens. This is possible through natural selection within genetically diverse populations. Tolerant or resistant individuals survive and intermate, get through the bottleneck, and the species evolves. Current citriculture is based on extremely limited …
Turkey is forecast to produce 249,000 metric tons (MT) of grapefruit in 2021–22, up 5% over the prior year, the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS) reported. The increased production is due to better yields resulting from favorable weather conditions in the Mediterranean growing region, USDA/FAS stated in its semi-annual report on Turkish citrus. Improved yields have allowed …
New research examining the cardiovascular health of young adults who consumed 100% orange juice (OJ) as children indicates no increased risk for high blood pressure or elevated blood lipid levels as a result. The research, published in the International Journal of Food Science and Nutrition, specifically looked at 100% OJ consumption during late childhood and early adolescence and its association …
Morocco in 2021–22 shipped a record 110.5 million metric tons (MMT) of fresh citrus to the United States, the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS) reported recently. That’s an increase of 156% over prior year shipments to the United States. Fresh tangerine and mandarin shipments to the United States increased 142% over the prior year, to 103.2 MMT. …
In Argentina, fresh orange production is forecast to increase to 920,000 metric tons (MT) in 2021–22, up 120,000 MT from previous estimates. Fresh tangerine production is estimated to increase to 400,000 MT. The projections were in a semi-annual report on Argentina’s citrus industry from the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS). PLANTED AREAOranges and tangerines are grown in …
By Xavier Martini Planting wildflowers in and around fields is known to provide food resources and habitats for beneficial arthropods like pollinators and predators of pests. In two locations (Lake Alfred and Monticello), University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers tested whether planting native Florida wildflowers next to citrus grove windbreaks could improve natural pest control …
By Ute Albrecht, Anas Fadli and Chandrika Ramadugu Most commercially available citrus scion cultivars are highly attractive to the Asian citrus psyllid and susceptible to HLB. There are some citrus species, however, that are HLB tolerant or resistant. This may be because they are less attractive to the psyllids and/or because they restrict pathogen proliferation and therefore HLB disease development. …
There is a growing trend of South African mandarin growers aggressively establishing new orchards under netting, the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS) recently reported. The practice has improved water efficiency, yields and the overall quality of fruit, USDA/FAS says in its semi-annual South Africa citrus report. USDA/FAS says the production of tangerines/mandarins in South Africa is anticipated …
Sustainability has been a buzzword in agriculture for years, often with varying definitions of what the term means. In recent years, many industries have adopted self-assessment tools to monitor their sustainability and report their results to their customers. Much of this monitoring and reporting is being done via online platforms. During Florida Citrus Mutual’s board of directors meeting held during …
The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) in late June announced updates regarding Mexican fruit fly (Mexfly) quarantines in Texas: On April 29, APHIS and the Texas Department of Agriculture (TDA) established a Mexfly quarantine in Lyford, Willacy County, Texas. APHIS and TDA established the Lyford quarantine following the confirmed detection of a mature …
Federal and state officials in late June expanded the areas quarantined for huanglongbing (HLB, also known as citrus greening), caused by Candidatus Liberibacter asiaticus, in California. The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) took the action in cooperation with the California Department of Food and Agriculture (CDFA). APHIS added portions of Los Angeles, Orange, Riverside …
The sweltering heat being felt across the Southeast has done little to dampen the optimism shared by one citrus grower who believes this year’s crop is “very promising.” Kim Jones, who owns a citrus packing facility in Monticello, Florida, and is part-owner of a similar facility in Tifton, Georgia, discusses the state of this year’s crop in North Florida and …
Fresh lemon production in Turkey for 2021–22 was recently forecast at 1.33 million metric tons (MMT) in an update by the U.S. Department of Agriculture’s Foreign Agricultural Service (USDA/FAS). That’s an increase of about 22% over expected prior year production of 1.1 MMT. Growers are expanding the area of their lemon orchards in part because lemons are more profitable than …
By Lourdes C. Pérez Cordero Management of the Asian citrus psyllid (ACP) in the HLB era is incredibly important. This well-known insect can vector and facilitate the spread of the bacterium associated with HLB disease. Therefore, effective reduction of ACP populations can be beneficial for the citrus industry. But how exactly do we manage this pest? Unfortunately, there is not …
The U.S. Department of Agriculture (USDA) announced proposed amendments to the Florida citrus marketing order. As recommended by the Florida Citrus Administrative Committee, changes would include reducing the size and quorum requirements of the committee and revising the nomination and selection processes of committee members. The requirement of allocating committee seats based on volume from each district would also be …
