Scientists in Brazil and Florida found that the direct examination of plant canopy temperature can assist in optimizing citrus irrigation management in greenhouses. The researchers were Gustavo Haddad Souza Vieira with the Federal Institute of Espírito Santo in Brazil and Rhuanito “Johnny” Ferrarezi with the University of Florida Institute of Food and Agricultural Sciences. Their study aimed to develop a …
By Pete Spyke and Bill Castle Navel oranges are fairly tolerant of HLB, are popular and easy to sell, and offer a stable source of income that is only marginally related to worldwide supply and demand. Nevertheless, the Florida navel orange industry has experienced some tough times recently. Growers are questioning whether it is possible to grow navel oranges profitably …

Florida orange and red grapefruit production, already at historically low levels, will likely decline for years, according to a leading citrus economist. Tom Spreen, University of Florida Institute of Food and Agricultural Sciences professor emeritus, calculated Florida crop output through the 2031-32 season based on various yield and tree replacement assumptions. Oranges and red grapefruit are Florida’s top-producing varieties. …
How modern citrus developed, particularly the popular mandarin variety, has long been a mystery to citrus breeders. A global partnership of scientists recently unraveled a big part of the mystery by analyzing the genome sequences of 69 East Asian traditional, wild and atypical citrus varieties. One of the researchers was Fred Gmitter, University of Florida Institute of Food and Agricultural …
Worldwide orange and orange juice (OJ) production are projected to climb in the 2020-21 market year, the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) reported recently. ORANGESGlobal orange output for 2020-21 is estimated up 2.5 million tons from the previous year to 48.6 million as favorable weather leads to a larger crop in Brazil (up 7%) and Mexico (up …
Improved sweet orange cultivars for processing and fresh fruit were the topic of a virtual presentation July 14 by plant breeder Jude Grosser.

Mandarin production in the European Union (EU) in 2020-21 is forecast to rise 21% from the previous year, to 3.4 million metric tons. The forecast, reported by the U.S. Department of Agriculture’s Foreign Agricultural Service, is almost 10% higher than the union’s 9-year average of 3.1 million metric tons. The higher production this season is mainly the result of expected …
Officials with the Citrus Research and Field Trial (CRAFT) program are considering giving future participating growers an incentive to plant more early- and mid-season oranges. The topic was discussed by CRAFT’s board of directors after board member Phillip Rucks pointed out there’s a trend for nurseries to propagate far more late-season oranges than early- and mid-season oranges. Tables that the …
By Megan Dewdney I did not need to visit my field trial to know that algal spot was in bloom on citrus in the last month. I have received many phone calls about it recently as growers notice the bright orange doughnuts on their tree limbs. For those unfamiliar with algal spot, it is a disease that occurs mostly on …
The U.S. Department of Agriculture’s (USDA) final 2020-2021 Florida orange forecast is 52.8 million boxes. California orange production edged out Florida with 54.5 million boxes of oranges. Texas oranges remained at 1.05 million boxes. The final Florida orange total is comprised of 22.7 million boxes of non-Valencia oranges (early, midseason and Navel varieties), unchanged from the June forecast, and 30.1 …
Citrus growers need as many tools in their toolbox as possible. With the Florida citrus industry decimated in recent years, mainly due to citrus greening disease, growers are exploring all options to help them succeed. CYAN 365®, a biostimulant from C Green Ag Biotechnology, is one tool that has proven to help enhance the quality and size of citrus crops, …
Fruit drop “is probably the No. 1 concern” of the citrus growers he knows, says Ray Royce, executive director of Highlands County Citrus Growers Association (HCCGA). “Fruit drop and profitability are going hand in hand,” he adds. “There’s a tremendous struggle now to be profitable, given the relatively low harvest numbers,” Royce says. “I think growers believe that if they …
By Davie Kadyampakeni, Tanyaradzwa Chinyukwi, Alan Wright and Rhuanito Ferrarezi The development of an efficient nutrition program for citrus trees provides the essential elements for optimum tree growth and yield. Tree performance is reduced when an essential element is deficient, while an excessive amount leads to plant toxicity and hinders overall tree performance. In citrus production, adequate fertilization rates help …
Growers looking for advice on the subjects of rootstocks and varieties will find several pertinent articles in the July issue of Citrus Industry magazine. According to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) citrus breeder Jude Grosser, Orie and Louise Lee (OLL) oranges are giving Valencias a run for their money. He discusses the beneficial characteristics of …
By Larry Duncan, Johan Desaeger and Homan Regmi Two field experiments were initiated in January 2019 to evaluate the efficacy of nematicides and cover crops for managing the sting nematode (Belonolaimus longicaudatus) in a replanted grove affected by huanglongbing (HLB). The trees were nearly two years old when perennial peanut (resistant to sting nematode) plots were established in row middles …
By Ariel Singerman and Stephen H. Futch In the 2020–21 citrus season, fruit drop has severely impacted orange yield in Florida.

By Bill Castle Creation, evaluation, release and commercial acceptance are dynamic, interactive activities that together constitute new rootstock development. Underpinning each of them is a commonly overlooked and rarely mentioned activity, professional judgment. Yet, it is something everyone has and recognizes as getting better with time and experience. It is a skill developed and refined over time from knowledge of …
