Recent research describes in detail how HLB causes damage to citrus trees and presents the case that HLB is a pathogen-triggered immune disease. A pathogen-triggered immune disease results from the activation of an organism’s immune cells fighting a pathogen. Nian Wang, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, took part in the research. This is the …
There has been quite a bit of interest in the Citrus Research and Field Trials (CRAFT) program. During the Florida Citrus Show held in Fort Pierce in late January, a panel of citrus growers discussed projects they have been approved to conduct under CRAFT. Tamara Wood, executive director of the CRAFT Foundation, moderated the panel and provided an update on …
The horticultural characteristics of new citrus varieties are important, especially in the era of HLB when disease tolerance is critical. But how the fruit tastes and other consumer attributes are equally important. That’s why citrus variety display days are vital in citrus breeding. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in …
By Megan Dewdney Spring is around the corner, and Florida’s first wave of bloom is here. But there is no time to relax and enjoy the flowers because citrus diseases wait for no grower. Young fruitlets become susceptible to canker toward the end of March to the beginning of April. Missing that key window of protection — if the weather …
By Megan Dewdney Mid-summer to fall has become algal spot season in my office. The disease is re-emerging in Florida for unknown reasons. While much of the year algal spot is low key and hard to spot, between June and September it is very obvious. So, what is algal spot, should you be concerned, and what can you do about …
With more than two weeks past since the late January freeze in Florida, citrus growers are still assessing the fallout. Some key production regions saw the coldest temperatures in years. With HLB endemic, there’s a lot of unknowns how trees will react to the stress the cold temperatures induced. However, some growers didn’t have to wait to see damage to …
The Florida citrus industry has been focused on finding solutions to the fruit drop problem that has hit groves hard in recent years. During the 2022 Florida Citrus Show in Fort Pierce, Fernando Alferez, University of Florida Institute of Food and Agricultural Sciences, assistant professor of citrus horticulture, presented findings from a research trial aimed at reducing fruit drop. The …
By Ozgur Batuman, Sanju Kunwar and Ana Redondo There are new products that potentially can be added to a grower’s toolbox in coming seasons for managing citrus bacterial canker. Citrus canker is an infection by a species of bacteria (Xanthomonas citri subsp. citri) that causes fruit blemishes and fruit drop. It makes fruit unsightly and lowers its marketability. Every year, …
Florida’s projected 2021–22 orange crop was reduced by 1 million boxes, to 43.5 million boxes, in the February citrus crop forecast from the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service. The forecast was released Feb. 9. The entire orange reduction was in the to-be-harvested Valencia crop, which was reduced 4% to 26 million boxes. The forecast for non-Valencia …
By Megan Dewdney The 2021 foliar fungal season was an easier than average year. The La Niña weather pattern predicted last fall came to pass, and the spring was relatively dry from January to the end of May with some rain in February and April. While citrus trees in Florida were likely drought-stressed, the dry weather slowed the usual decomposition …
Cold temperatures the mornings of Jan. 29 and Jan. 30 did more citrus damage than an initial report indicated, Highlands County Citrus Growers Association Executive Director Ray Royce said. Royce issued the following update on Feb. 1: “The coldest weather in at least four to five years has left much more damage behind in parts of the South-Central Florida region …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is committed to updating nutrient management recommendations for citrus. For the next two months, that means seeking state funding for the research. The UF/IFAS team was crafting a specific proposal to the Legislature as of this writing. It’s at the very top of …
Increased water availability and the expectation of more harvest labor, along with increased planting area, are reasons for the citrus crop forecast increase in Australia, according to the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS). FAS recently reported that the total planted area of navel and Valencia oranges in Australia has increased by 14% from 15,307 hectares (ha) in …
By Ariel Singerman According to the U.S. Department of Agriculture (USDA), production of processed oranges in Florida will decline again this season (Figure 1). If such a forecast materializes, production will have declined by approximately 80% since HLB was first found in the state. The Florida Department of Citrus reports that, as a consequence of COVID-19, orange juice demand has …
The U.S. Department of Agriculture (USDA) National Agricultural Statistics Service released its monthly U.S. citrus production forecast on Jan. 12. ORANGESThe report showed another 3% drop in Florida orange production down to 44.5 million boxes. The initial forecast in October predicted 47 million boxes. The forecast for all oranges fell by 1.5 million boxes from the December report. Florida’s non-Valencia …
Florida citrus growers and orange juice processors are reporting low Brix levels as the 2021–2022 harvest season continues. The Jan. 10 edition of the Market News Bulletin from Florida Citrus Mutual noted average Brix of 9.83. According to Bob Behr, chief executive officer of Florida’s Natural Growers, juice oranges being harvested now are running below average. “Citrus greening continues to …
Egypt is expected to maintain its position as the world’s leading fresh orange exporter in 2021–22 despite production challenges, the U.S. Department of Agriculture’s Foreign Agricultural Service (FAS) reported. The country is expected to export 1.45 million metric tons (MMT), down from 1.67 MMT in 2020–21. The decrease in exports is attributed to lower production amid unfavorable climate conditions. Russia, …
By Tripti Vashisth In a multi-year field trial, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have seen beneficial effects of gibberellic acid (GA) on Valencia sweet oranges. Monthly application of GA (September to January) on Valencia improved yield on average by 30%, reduced fruit drop and elicited enhanced plant defense response. These benefits are possibly due …
By Frank Giles The U.S. Department of Agriculture (USDA) reported a drop in estimated Florida orange production in its December crop update. That estimate lowered production by 1 million boxes from the initial forecast of 47 million boxes reported in October. In advance of USDA’s January estimate, Florida citrus growers discussed how their crops are progressing. Here’s what they had …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers have found that gibberellic acid (GA) applications can improve productivity of HLB-affected Valencia trees. But some growers are concerned that the GA label may not allow that use. Citrus Research and Education Center Director (CREC) Michael Rogers allays that concern. Rogers says some are concerned “because the recommendations that …
