The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) on Oct. 16 presented a hurricane recovery webinar less than a week after Hurricane Milton crossed the state. Among the topics addressed were damage assessment and fruit drop. DAMAGE ASSESSMENT Multi-county citrus Extension agent Chris Oswalt recommended that growers check trees for damage in multiple locations within groves, starting …
By Tripti Vashisth and Taylor Livingston Hurricane Milton passed over many citrus-producing counties in Florida, resulting in canopy and fruit loss (especially in early varieties). HLB-affected trees undergo a lot of stress, and now the hurricane has added more abiotic stress to trees. High-speed winds caused significant fruit and leaf drop. The fruit and leaves that escaped the drop during the …
By Tripti Vashisth Over the past decade, HLB-associated fruit drop has become a significant problem in Florida groves. Many growers opt to harvest the fruit before the peak fruit drop begins. However, the downside to this strategy is that the fruit does not get enough time for optimal Brix accumulation. Plant growth regulators, when applied at the right time, can …
KeyPlex recently hosted its third Saving Citrus Symposium in Sebring, Florida. The event focuses on fruit drop, which has been a major problem for growers in recent years. The third gathering provided an update on research KeyPlex has sponsored to seek causes of fruit drop and ways to manage against it. The research began in January 2021 when company personnel …
By Chris Oswalt During this time of the year, Florida growers should be aware of the potential for the development of citrus brown rot disease. It can infect fruit at color break. If severe, the disease can cause a significant amount of infected fruit to drop. For this reason, groves with a history of brown rot in areas that recently …
KeyPlex has scheduled a citrus symposium for July 25 at the SEVEN Sebring Raceway Hotel. The meeting will focus on research conducted by Vladimiro Guarnaccia, associate professor of plant pathology at the University of Torino in Italy. He will present evidence on the origins of fruit drop. Research sponsored by the European Union and KeyPlex at the University of Torino …
By Fernando Alferez, Daniel Boakye, Murillo De Sousa and Pablo Orozco After HLB was first detected in Florida, increase in disease-associated preharvest fruit drop in affected trees has significantly reduced grower returns. Fruit drop is normal in healthy citrus, accounting for 10% to 15% of the total crop. However, under endemic HLB conditions and depending on the variety, crop loss …
By Megan M. Dewdney Postbloom fruit drop (PFD) is a sporadic flower disease. It is primarily caused by the fungus Colletotrichum acutatum. While infections only occur on flowers, the fungus is present on trees throughout the year. It survives by producing resting structures on leaves and stems. How the inoculum survives multiple years between infections is still unclear. The fungus …
A week before Hurricane Ian tore across Florida, Glenn Beck of Beck Bros. Citrus reported that there were hopeful signs for the coming season. Fruit in his better-looking groves were in the size range that tends to hold on trees until harvest. Beck, and his brother Mark, own and manage citrus groves across the state. He says each day since …
Alico, Inc. reported on Sept. 30 that initial observations following Hurricane Ian indicate there was significant drop of fruit in its groves. However, most trees remain intact. The magnitude of the fruit drop will be formally calculated by the company’s staff and insurance companies in coming weeks. Alico has 48,900 acres of citrus groves in Charlotte, Collier, DeSoto, Hardee, Hendry, …
Growers know the negative impacts of any kind stress on trees infected by HLB. That raised a question: Can injury from herbicides make fruit drop worse? Ramdas Kanissery, an assistant professor of weed science with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), conducted a research project to help answer that question. Kanissery discusses the research in …
Brazil’s Fundecitrus recently pointed out that fruit flies, along with citrus fruit borers, are primarily responsible for the country’s citrus fruit drop. The organization suggested that monitoring and management must be taken to avoid economic damage, since fruit flies occur throughout the year. Fundecitrus described the fruit flies that cause damage in Brazil and suggested control measures. Two species of …
Weed scientist Ramdas Kanissery’s research has not shown evidence that herbicides, including glyphosate, increase citrus fruit drop or decrease yields. But in studies using different glyphosate rates, he did find that there is a relatively strong negative correlation with the fruit detachment force and the glyphosate amount applied. “That means there may be something happening with the higher glyphosate rate” …
Florida citrus growers can learn more about the use of plant growth regulators (PGRs) in the fight against fruit drop at an upcoming online seminar. The webinar will be at 10 a.m., April 27 and will be presented by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). Speakers at the webinar, titled “Gibberellic Acid Research Update and …
A La Niña weather pattern is most likely this spring, with higher-than-average temperatures and below-average rain predicted in Florida, researcher Megan Dewdney reported in a Feb. 24 presentation about postbloom fruit drop (PFD). That could have some influence on the severity of PFD, since its preferred climate is humid and subtropical, and the fungus moves with rain splash and wind-borne …
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 …
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 Megan M. Dewdney Postbloom fruit drop (PFD) is a flower disease mainly caused by the fungus Colletotrichum acutatum. The fungus is present on citrus trees throughout the year but survives by producing resting structures on leaves and stems. The fungus becomes stimulated to produce spores by substances from the early flowers. These early spores infect the initial flowers and …
The Citrus Research and Development Foundation (CRDF) governing board on Jan. 25 approved a project aimed at reducing fruit drop by using potassium, zinc, gibberellic acid and the herbicide 2,4-D in different timing scenarios. The funding will allow University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher Fernando Alferez to finish two years of work that CRDF Chief …
One instance of fruit drop is expected and needed every growing season for Florida citrus producers. A second instance, however, is unexpected, unwanted and just what growers do not need right before harvest time. HLB WORSENS DROPBut that is a scenario Florida citrus growers encounter every year. This problem has only worsened in the era of citrus greening disease, also …
