Below you'll see everything we could locate for your search of “brassinosteroids”
Growers have been deploying several new therapies aimed at improving the health of HLB-infected citrus in recent years. Plant growth regulators like gibberellic acid, 2,4-D and brassinosteroids have demonstrated the ability to improve tree health and help in fruit retention. More recently, direct delivery of oxytetracycline hydrochloride (OTC-HCl) via trunk injection has been approved for use in groves. There is …
By Ruth Borger Keeping up with the latest news and research findings that impact how growers can successfully produce citrus in the HLB era can be an overwhelming task. Tracking down the right information at the right time for the changing conditions that face citrus growers takes time, effort and persistence. University of Florida Institute of Food and Agricultural Sciences …
The use of individual protective covers (IPCs) to safeguard young citrus trees from HLB has become a common practice in Florida groves in recent years. Fernando Alferez, an assistant professor of citrus horticulture with the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), has led the research effort to study IPCs and their effectiveness in preventing HLB. He …
Researchers and growers have found that individual protective covers (IPCs) can keep young trees free of HLB for two or more years while providing additional benefits like improved tree growth. The IPCs work by keeping HLB-infecting Asian citrus psyllids out of the tree canopies. But trees outgrow the covers and must eventually be removed. Researchers have found that about 60% …
The Citrus Research and Field Trial (CRAFT) Foundation has extended the deadline for CRAFT Cycle Four to Dec. 31 at 5 p.m. It made the extension in response to multiple requests. The foundation recognized that many Florida citrus growers have had to shift their focus and time for the past couple of months to deal with hurricane recovery. GROWER INCENTIVESCRAFT …
Seven entities recently received $21.7 million to conduct research into combating and preventing HLB at the farm level. The funding is from the U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA NIFA) Emergency Citrus Disease Research and Extension program. The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) received the majority of the funding, more …
As the 2022–2023 harvest season kicks off, Glenn Beck of Beck Bros. Citrus is hopeful for a better season than last year. He has witnessed the groves he owns and manages suffer the effects of HLB over the years. When it comes to managing the disease, Beck has a simple philosophy: Stick with a solid production plan. He acknowledges that …
By J. Scott Angle, jangle@ufl.edu, @IFAS_VP Just as HLB can affect fruit flavor, so can our numerous innovations to manage HLB. Yu Wang works to make sure our solutions are sweet. When the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) hired her as a flavor chemist seven years ago, Wang worked primarily with breeders. Her objective was …
Multi-county citrus Extension agent Ajia Paolillo discussed the role of plant growth regulators (PGRs) in groves in a recent Extension newsletter. She cited University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) horticulturists Tripti Vashisth and Fernando Alferez as sources. Here’s a summary of Paolillo’s article: GIBBERELLIC ACIDGibberellic acid (GA) is one of the PGRs used in citrus. It …
Over 60 citrus industry representatives gathered Aug. 25 for the 61st annual Packinghouse Day at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center in Lake Alfred. They heard updates on H-2A visa options for packinghouse workforce needs, an overview of citrus fruit export requirements and an update on food safety auditing. Faculty …
The Citrus Research and Development Foundation (CRDF) Research Management Committee and board of directors recently approved projects for funding. The first CRDF research project has approval for funding of a final year of research by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to study the lebbeck mealybug and its management. “The Research Management Committee debated this …
The Citrus Research and Development Foundation (CRDF) held its April board of directors meeting to hear reports on projects involving 2,4-D, gibberellic acid, brassinosteroids and zinc. According to Rick Dantzler, chief operating officer of CRDF, the foundation is conducting a full-court press to study how these materials can combat fruit drop and improve quality. CRDF staff also presented a proposal …
Researchers offered updates on products proven to help against the devastating citrus disease HLB in a virtual seminar on April 27. University of Florida Institute of Food and Agricultural Sciences horticulturists Tripti Vashisth and Fernando Alferez discussed the benefits of gibberellic acid (GA) and brassinosteroids, respectively. Vashisth reported that GA-treated Valencia orange trees dropped less fruit and increased fruit yields …
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 …
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 …
All indications are that the recent widespread use of individual protective covers (IPCs) on young citrus trees in Florida is beneficial, especially for excluding Asian citrus psyllids and the HLB they spread. If there is any downside, it may be that some other pests and diseases are more prevalent under IPCs. In a recent American Society for Horticultural Science webinar, …
Five Citrus Research and Field Trial (CRAFT) Technical Working Group leaders on Aug. 31 discussed the types of projects they’d like to see CRAFT Cycle III growers pursue. The types of projects the leaders expressed interest in will, to some extent, fill gaps in knowledge expected to be gained from previous cycles. CRAFT pays Florida growers to plant trees on …
Preventing HLB infection in newly planted citrus trees with individual protective covers (IPCs) can improve productivity and fruit quality. Thus far, IPCs have kept young citrus trees free of HLB in research plots. “Once you plant a tree, if it’s not protected, it’s exposed to HLB infection from day one,” says Fernando Alferez, an assistant professor at the University of …
Sometimes growers must think outside the box to remain sustainable amid high input costs and devastating diseases. That is the situation facing citrus growers who are struggling to remain viable in the era of citrus greening. What if seaweed could be used to aid in the quality of citrus production? Seaweed is a biostimulant that is part of the biological …
By Fernando Alferez, Christopher Vincent and Tripti Vashisth In the current scenario of widespread infection and severe symptoms of HLB in Florida, horticultural practices that improve plant health in the presence of the disease are needed. For this reason, we sought to follow up on reports of positive effects of a brassinosteroid on infected plants. Brassinosteroids are a relatively newly …
