One bad apple can spoil the bunch. The same can be said for Georgia citrus. That was the message shared by Beth Oleson, director of food safety and education for the Georgia Fruit and Vegetable Growers Association, during the Georgia Citrus Association’s (GCA) annual meeting on Feb. 28. She spoke with growers about food safety and applauded GCA’s leadership. “We …
IPCs Improve Fruit Yield and Quality
By Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi and Mongi Zekri University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers established a field trial in February 2018 to evaluate the efficacy of individual protective covers (IPCs) to prevent Asian citrus psyllids from spreading HLB and to study the effects on tree growth and physiology. The …
Growers in Northern Regions Whetting Consumer Appetites
Citrus production in North Florida, South Georgia and South Alabama continues to expand rapidly. That increased production led to a successful marketing year for producers, says grower Kim Jones, who owns a citrus packing facility in Monticello, Florida, and is part-owner of a similar facility in Tifton, Georgia. “We’re selling every piece of fruit we pulled into both sheds this …
Early HLB Detection by Dogs
By Amir Rezazadeh Huanglongbing (HLB), or citrus greening disease, has caused more than 70% decline in the production of oranges for juice and the fresh market in Florida. Once a tree is infected, there is no cure. Early detection followed by a rapid response is important to avoid further spread of the exotic pathogen. Delayed detection of HLB can result in …
HLB Update in Georgia
A small amount of citrus greening disease (huanglongbing or HLB) can escalate quickly if growers are not careful. Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, cautioned producers about the disease during the recent Georgia Citrus Association meeting. “The issue is not widespread yet (in Georgia) for sure,” said Oliver. “We don’t think the vector 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 …
Who Should Be the Next Citrus Achievement Award Winner?
It is that time of year again when we seek nominations for the next Florida Grower Citrus Achievement Award winner. Since 2000, the honor has grown into the gold standard of industry recognition for those who have made and continue to make a significant impact within and even beyond the Florida citrus community. The Citrus Achievement Award is presented to …
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 …
‘Irma Will Haunt Us’ Regarding Citrus Black Spot
Citrus black spot (CBS) disease has only been found in five Southwest Florida counties, but that could change as a result of 2017’s Hurricane Irma, a researcher reiterated recently. University of Florida Institute of Food and Agricultural Sciences plant pathologist Megan Dewdney, in a Feb. 24 presentation, said “Irma will haunt us for a while.” She explained that Irma likely …
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 …
Talking Citrus for 60 Years
By Ernie Neff In every Florida citrus community, there are many growers who have been close friends most of their lives. They grew up in the country or small cities not far from each other, went to the same high schools and know the same people. They share the struggles — and before HLB, the joys — of growing citrus. …
Guidance on Chlorpyrifos Recordkeeping
By Brett Bultemeier and Lauren Diepenbrock The revocation of chlorpyrifos residues and tolerances that became effective on Feb. 28, 2022, caused some confusion and concern when it was first announced. The legal description provided by the Environmental Protection Agency is challenging to fully understand. Therefore, the Pesticide Information Office from the University of Florida Institute of Food and Agricultural Sciences …
Florida Citrus Growers Seeking Solutions to Fruit Drop
Fruit drop has plagued Florida citrus groves in recent years. The problem has been a major factor in tumbling yields. The February 2022 U.S. Department of Agriculture’s citrus crop forecast put Florida’s orange estimate at 43.5 million boxes. If realized, it would represent an 18% decline in the crop from last season. Growers are turning over every stone to seek …
Get Canker Before It Gets You
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 …
Florida Citrus Growers Say Freeze Damage Still Unfolding
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 …
Grapefruit Crop to Rise in European Union
European Union (EU) grapefruit production is forecast to grow 2.8% to 108,000 metric tons (MT) in 2021–22, according to the U.S. Department of Agriculture’s Foreign Agricultural Service. The increase is due to an almost 4% expected increase in Spanish grapefruit production. Spain is the major EU grapefruit producer at 84,000 MT. EU grapefruit planted area stands at around 3,600 hectares …
What to Do About Bingo Stem Dieback
By Christopher Vincent, Megan Dewdney and Liliana Cano Bingo is a relatively new and unfamiliar variety, which growers initially sought as a positive alternative. However, it presents some unique production challenges. Bingo is desirable because its high-quality, low-seeded fruits are ripe in October, a valuable harvest window for Florida growers. But in the early years of its propagation, some nurseries …
