News for citrus growers around the globe
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 …
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 …
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 …
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 …
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 …
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 …
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. …
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 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 …
On Feb. 10, Fundecitrus and its cooperators released an update to Brazil’s 2020–2021 orange crop forecast. The forecast is now 269.01 million boxes, down slightly from the 269.36 million boxes forecast in December. While production of the Pera Rio variety increased 3.74 percent to 81.83 million boxes, Valencia and Valencia Folha Murcha production decreased 2.8 percent to 91.72 million boxes. …
Global orange production for 2020–21 is forecast to rise 3.6 million metric tons from the previous year to 49.4 million metric tons. Favorable weather leading to larger crops in Brazil and Mexico will offset declines in Turkey and the United States, according to the U.S. Department of Agriculture’s Foreign Agricultural Service. Consequently, consumption, processing fruit and fresh exports are also …
Alico, Inc., one of Florida’s largest citrus producers, announced financial results for the fiscal quarter ending Dec. 31. Some highlights regarding the company’s citrus operation follow. For the quarter, Alico Citrus harvested approximately 0.8 million boxes of fruit, a decrease of 14.6 percent from the first quarter of the prior fiscal year. The decrease was principally related to there being …
The February Florida orange forecast released by the U.S. Department of Agriculture (USDA) is 56 million boxes, up 2 million boxes from the January forecast. This represents a 4 percent increase from the January forecast. If realized, it will be 17 percent less than last season’s final production. ORANGESThe forecast change was for non-Valencia production, which now stands at 22 …
Florida’s citrus growers are counting on research to help sustain what’s left of an industry decimated by huanglongbing (HLB). The disease remains a focal point of research at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Scott Angle, vice president for agriculture and natural resources at UF/IFAS, understands the ramifications if improved HLB management options aren’t available …
By Andre B. Gama and Megan M. Dewdney Postbloom fruit drop (PFD) of citrus is a disease caused mostly by the fungus Colletotrichum acutatum. This fungus survives by producing resting structures on leaves and stems. When flowers start to appear in groves, these resting structures produce spores that can cause PFD. However, the fungus requires specific weather conditions to be …
The Cold Hardy Citrus Association (CHCA), founded in 2017, was established to ensure all growers, large and small, have a unified voice in an emerging industry and to provide education on best management practices in light of HLB. CHCA members include growers, packers, processors, industry suppliers, nurseries, consultants, homeowners and academia representing Florida, Georgia, Alabama, Louisiana and Mississippi. Kim Jones …
By Megan Dewdney There were many challenges in 2020, but fortunately the Florida season for foliar citrus diseases was relatively normal. Little to no postbloom fruit drop (PFD) was reported during the 2020 bloom because of a sudden dry spell as the flowers opened. As spring 2021 approaches, the forecast is for a La Niña weather pattern with slightly warmer …
