Fruit Size and Spraying Interval Are Key for Canker Control
The size of fruit that should be sprayed, the spraying interval and ways to avoid copper phytotoxicity were among the citrus canker topics plant pathologist Megan Dewdney offered growers recently. Dewdney said fruit are most susceptible to canker when they are between 3/8 inch and 1.5 inches in diameter. The fruit rind becomes much more resistant when the fruit is …

Donaldson Tree Is ‘Beacon of Hope’
A recently discovered HLB-infected tree that is producing high levels of fruit holds hope for Florida’s citrus industry, according to Florida Citrus Commission (FCC) Chairman Steve Johnson. “By now, many of you have heard about the Donaldson tree,” said Johnson. “Recently rediscovered at USDA’s (U.S. Department of Agriculture) Whitmore Farm, this decades-old tree is abundantly producing early-season oranges and despite …
Soil Is Key to Setting Up Trees for Success
By Brad Turner As I started my regenerative journey five years ago, it conjured up memories of walking the family groves in the 1970s with my freshly sharpened eye hoe. I would follow the tractor as it pulled the offset chopper, crisscrossing between the widely spaced trees in all directions. The native grasses and broadleaf plants — including legumes like …
Mandarin Crop Losing Ground in Europe
In 2021–22, European Union (EU) mandarin production is forecast to decline 7.5% from the previous year to 2.9 million metric tons (MMT), according to the U.S. Department of Agriculture’s Foreign Agricultural Service. EU mandarin production may also be almost 5.5% lower than the 10-year average production of 3.1 MMT. The shortage in EU mandarin production is mainly the result of …
Lemon Production in Turkey to Skyrocket
Lemon production in Turkey is expected to increase 27% to 1.4 million metric tons (MT) in 2021-22, the U.S. Department of Agriculture’s Foreign Agricultural Service reported recently. Last season, lemon production reached 1.1 million MT. Producers are increasing orchard areas due to lemon’s profitability compared to other citrus fruits. The main problems reported by lemon producers in Turkey are diseases …
Black Core Rot Being Studied
A new Hort Innovation project aims to shed some light on how black core rot happens in Australian groves so the citrus industry can learn how to better manage the disease. Black core rot caused by the fungus Alternaria spp. can be a problem for some citrus growers in the southern growing areas in Australia. Citrus infected with Alternaria spp. …
Flavor Summit Delves Deep Into the Science of Taste
In late February, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hosted its second annual Flavor Summit. The hybrid in-person/online event was held at the Citrus Research and Education Center (CREC) in Lake Alfred. CREC and the UF Center for Smell and Taste hosted the event that took a deep dive into the science of how flavors …
Pointers for Pre-emergent Herbicide Use
By Ramdas Kanissery Weeds emerging in citrus rows are problematic as they compete for resources with the trees, support pests and interfere with grove operations like irrigation (Figure 1). Hence, effective strategies to control weed emergence should be in place. Pre-emergence (or residual) herbicides are an excellent tool for the long-term suppression of weeds in tree rows. These herbicides …
New Research Shows How HLB Damages Trees
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 …
Finger Limes to Be Focus of Online Event
Finger limes will be the topic of a March 23 virtual symposium sponsored by the University of Florida Institute of Food and Agricultural Sciences Citrus Research and Education Center (UF/IFAS CREC). Finger limes are a unique citrus variety gaining interest among chefs, foodies and citrus growers. The symposium, targeted to commercial citrus and specialty crop growers and marketers, will be …
Controlling Mites in CUPS
Emilie Demard is working to control mites and other pests that damage fresh grapefruit growing as citrus under protective screens (CUPS) at the Indian River Research and Education Center in Fort Pierce. “I look at biological control — in this case, predatory mites controlling pest mites to minimize the need for agrochemicals,” said Demard, a Ph.D. entomology graduate with the …
Slow Progress for Port Problems
California ports remain a critical logjam for products shipped in or out of the country. However, fresh fruit, including California citrus products, is managing to get to foreign markets. Shipping specialist Taylor Ball said “Fruit is getting shipped, but there is a lot of stress and worry involved. But demand remains high, and the prices are good.” Ball manages West …
Florida Growers Detail CRAFT Projects
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 …
Orange Juice in Europe: Production, Consumption and Trade
European Union (EU) orange juice (OJ) production is forecast at 70,390 metric tons (MT) in 2021–22, the U.S. Department of Agriculture’s Foreign Agricultural Service reported. That’s a drop of almost 10% compared to the previous period due to the expected decline in EU orange supply. Spain is the major orange processor in the EU, followed by Italy. Approximately 20% of …
No More Satsumas: The Time Is Ripe to Diversify
South Georgia and North Florida industry leaders preached diversification to citrus growers at the Georgia Citrus Association annual conference. The event took place Feb. 28 at the University of Georgia (UGA) Tifton Conference Center. No longer should satsuma mandarins be the crop of choice for potential growers. There are other viable options for farmers to choose from, said Lindy Savelle, …
