The leading producing areas in Spain include …
Citrus Greening Solutions: How Long Will It Take?
It may not be the answer Florida citrus growers want to hear, but it is likely to be several years before a citrus greening remedy is put in place to combat the destructive disease. University of Florida professor Fred Gmitter shared his assessment on possible citrus greening solutions during a recent American Seed Trade Association webinar. “We learn a lot …
FDOC on Global Marketing Efforts
A 25 percent tariff placed on Florida grapefruit in Europe has had some impact on retail supply, Florida Department of Citrus (FDOC) Director of Global Marketing Samantha Lane told the Florida Citrus Commission (FCC) in early February. The FCC is the FDOC’s governing board. Lane said the FDOC worked with the European industry to ensure Florida-loyal retailers continued to have …
Global OJ Production to Exceed Consumption
Global orange juice (OJ) production for 2020-21 is forecast 17 percent higher to 1.8 million tons. Production in Brazil and Mexico more than offsets the drop in the United States. However, global production continues its general long-term decline, according to the U.S. Department of Agriculture’s Foreign Agricultural Service. Similarly, consumption is projected to continue its long-term decline, although exports are …
Texas Freeze Leaves Citrus Crop in Trouble
The historic cold snap that has frozen Texas this week has left citrus growers with little hope for saving their crops. “We’ve had the perfect trifecta this season,” says Dale Murden, citrus grower and president of Texas Citrus Mutual. “We’ve endured the lingering drought, Hurricane Hanna and now the St. Valentine’s Day Massacre — all on top of the pandemic. …
Georgia Citrus Conference to Be Online
Due to COVID-19, the 2021 Georgia Citrus Association (GCA) Conference will not be held in person. Instead, the GCA is launching a new website and membership platform. This state-of-the-art tool will allow members to view presentations by experts at any time. Topics include weed management, citrus diseases and disorders, testing for diseases, precision agriculture, crop insurance, cold protection and the …
Thrips Management Tips
As Florida growers prepare for the spring bloom, it is time to think about a pest that thrives on citrus flowers: thrips. Most notably, flower thrips are known to cause damage to developing flowers in sweet orange. Feeding damage can range from negligible to causing abortion of the flower or developing fruitlet. This pest is particularly challenging because it migrates …
Fermented Food Waste for Fertilizing Citrus
Fermented food waste converted to liquid fertilizer and fed through drip irrigation can boost bacteria that increase crop growth, according to a new University of California Riverside (UCR) study. The treatment may also make plants more resistant to pathogens. “Beneficial microbes increased dramatically when we added fermented food waste to plant growing systems,” said UCR microbiologist Deborah Pagliaccia, who led …
Coordinated Treatment Planned for California Citrus
Citrus growers and industry members recently gathered virtually to discuss the Asian citrus psyllid (ACP) and huanglongbing disease (HLB) situation throughout the Central Valley of California. The reason for the concern is a negative trend seen in 2020. ACP DETECTION HISTORYACPs, the vectors for the disease, are widespread in Southern California where HLB-infected trees have been found. There are ongoing …
Stem Pitting Disease Caused by Citrus Tristeza Virus
By Amit Levy, Peggy Sieburth and Ozgur Batuman When we hear or read about citrus tristeza virus (CTV), we usually think about the decline of sweet orange or grapefruit trees on sour orange rootstocks. However, there are other diseases caused by different isolates of the virus. One of these diseases is stem pitting, mostly caused by the VT isolate of …
Georgia Owari Rootstock Trial Update
Ongoing citrus rootstock trials being conducted by the University of Georgia (UGA) hold promise for Georgia’s growing citrus industry. Jake Price, UGA Extension agent and Lowndes County Extension coordinator, has produced six local citrus rootstock/variety trials with varying objectives. The oldest trial, planted in 2014, is growing Owari satsuma trees on standard and new trifoliate hybrid rootstocks. Each year, as …
Ag Workers Among Those Most at Risk to COVID-19 Death
A new study from the Centers for Disease Control and Prevention found that food-service, agricultural and construction workers were among the most at-risk for dying from exposure to COVID-19. The study points out high-density workplaces in any industry are possibly high risk. The close proximity of employees in high-density workplaces creates a high risk for transmission of coronavirus disease. The …
Nutrition Management Program Yields Results
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have found that following nutrition and irrigation guidelines designed for a specific grove will help growers promote tree health and produce high-quality citrus. Last year, UF/IFAS scientists offered Florida growers a unique nutritional counseling program, commonly referred to as the nutrition box program. It provides free soil and leaf …
Shade for HLB Trees Means More Yield
Like all photosynthetic plants, citrus trees need light to produce food. But in Florida, groves located in full sun sometimes receive more light energy than they can make use of, causing photosynthesis to slow down. When this happens, the trees invest their energy in protecting their leaves from sun damage, meaning the trees have less food available for fruit protection. …
Argentina Sweet Citrus Sees Increase
The U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) reported that sweet citrus production in Argentina is forecast to increase in 2020-21. Sweet citrus refers to fresh oranges and tangerines. Orange production is expected to climb 7.5 percent from the prior season to 700,000 metric tons; tangerine production is forecast to jump 16 percent to 360,000 metric tons. Sweet citrus …
European Lemon Production Trending Upward
European Union (EU) lemon production in 2020-21 is forecast to increase by almost 11 percent from last season, to 1.64 million metric tons (MMT), according to the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS). EU planted area for the citrus variety continues trending upward at around 78,000 hectares. Spain is the union’s largest lemon producer with a forecast of …
