Controlling Whitefly on Poinsettia

Unfortunately, poinsettia and sweet potato whitefly (Bemisia tabaci) go together like cats and fleas; if you have one, you’ll have the other. By this time (June) you should already be considering your whitefly management strategy. Here, we make a case for biocontrol as both a viable and economical way to control whitefly based on leading research supported by the American Floral Endowment (AFE) and many years of grower experience in Canada. The Problem with Pesticides Management of Bemisia whiteflies with pesticides can be difficult, if not impossible, in some years. This is because whiteflies that originate on cuttings (and those that fly in from field crops, as in the Southern US) have likely been exposed to multiple applications of several groups of…

Unwavering grant support, the platform to explore innovative and impactful research, and lifelong collaboration with those in our vibrant community have helped shape me into the person I am today. It has been a privilege to serve and contribute to an industry that breathes this kind of life, beauty, and camaraderie into the world.…

Passing of the Torch: AFE Research Director Dr. Terril Nell Retires

Dr. Nell has spent his entire career working for the benefit of the floral industry. He retired as Professor Emeritus of Floriculture after a 35-year tenure at the University of Florida, where he served as Chair of the Environmental Horticulture Department from 1991–2012. His research has led to the development of best practices and advances within the floral industry leading to improved flower and plant longevity. He has consulted for growers, wholesalers, and retailers nationally and internationally for over 40 years. A highly respected care and handling expert, Dr. Nell co-authored the Flower and Plant Care Manual produced by the Society of American Florists and Flowering Potted Plants: Prolonging Freshness by Ball Publishing. For the past nine years, Dr. Nell has served as the…

Manipulating Light to Improve Quality of Cut Flowers

Once completed, this research will provide growers with well-defined recommendations for vegetative and reproductive growth to increase cut flower production efficiency and profitability. Specifically, we are quantifying how several new and commercially important cut flower varieties respond to daylength and/or vernalization temperature and duration to ultimately determine how these environmental parameters should be managed to hasten flower initiation and induction without negatively impacting stem quality and yield. This information is especially crucial for cut flower growers located in northern latitudes as they transition to year-round greenhouse production.   Bluebeard (Caryopteris ×clandonensis) and Billy button (Pycnosorus globosus) are both crops that have been recently introduced as cut flowers, however, there is very little production and flower induction information available. These crops have the…

A Year in Review: A Look Back at 2023

As the year comes to a close, we invite you to celebrate all that the Endowment has been able to accomplish and provide through your ongoing support. What a year it’s been! We couldn’t have done it without you. Together, we have granted over $675,000 in funding this year to support research, internships, scholarships, and education for the entire floral community. Consider making a contribution to support us continuing this great work next year! Here are some key highlights from 2023: Research and advancements are key to the industry’s ongoing growth and success. This year, we have funded 12 ground-breaking research projects, including five new projects and seven continuing projects. The projects are working to move the industry forward and help solve some of…

2024 National Floriculture Forum: A Gathering of Floriculture Experts and Educators!

We cordially invite floriculture stakeholders from academic institutions, governmental agencies, and the floriculture/greenhouse industry to join us in Biloxi for the 2024 National Floriculture Forum (NFF) taking place from Thursday to Saturday, February 22-24, 2024. For over two decades, dedicated faculty and educators have collaborated to organize these annual events that promote unity, communication, and advancement within the floriculture community. .“After a pause due to the global pandemic, the 2024 National Floriculture Forum will make an exciting return, bringing together industry leaders, researchers, and students in the spirit of collaboration and innovation that has long defined the floricultural community,” Dr. Jim DelPrince, this year’s conference co-chair, said. “This event holds great significance as we move forward together, addressing the challenges and opportunities that lie…

Optimizing the Efficacy of Beneficial Bacteria Against Botrytis Blight in Greenhouse Crops

Botrytis cinerea is the causal agent of botrytis blight or gray mold, the most common and economically devasting disease for greenhouse crops. Fungicides are routinely used to control Botrytis; however, some Botrytis strains are developing resistance to those chemicals. Beneficial bacteria have been used successfully as biological control agents for disease control. The Jones laboratory at Ohio State University has screened a collection of beneficial bacteria to identify strains that can control Botrytis blight in petunia. These experiments have identified some strains of Pseudomonas bacteria that are effective microbial biocontrol agents (MBCAs). We have characterized these bacteria to identify potential modes of action by which they inhibit the severity of Botrytis blight. This research was made possible by a research…

A Spotlight on Thrips and Botrytis Management at Cultivate 2023

An incredible 188 people attended AFE’s educational session “Effective Management of Thrips and Botrytis” at Cultivate ’23 this July. It was one of the highest attended sessions in the history of the event.   This session was part of the American Floral Endowment’s Thrips and Botrytis Campaign, an initiative aimed at reducing the impact of these pests on the floriculture industry. Dr. Rose Buitenhuis from Vineland Research and Innovation Centre shared insights into the components of a successful thrips IPM program, including identification of different thrips species and biological control. Dr. Jim Faust from Clemson University focused on the recommended techniques for reducing botrytis from the greenhouse to the postharvest environment. The session provided participants with practical information that could…

Longer-Lasting Cut Flowers: The Subzero Solution

Discover how cutting-edge research can help flower growers store flowers for longer durations, ensuring blooms remain fresh and vibrant for extended periods. Hear the direct findings from AFE-funded research along with accessing the full research report. Average vase life visual representation of stored rose ‘Freedom Red’ flowers compared to non-stored control flowers after 4- and 8-week storage durations held at 31°F (-0.6°C) or 39 °F (4°C).Cold storage of cut flowers is often a necessity. On most farms, it is impossible to harvest enough flowers to satisfy the immediate needs of all customers and markets. Storing cut flowers at cold temperatures of 35-39°F reduces respiration and transpiration, allowing them to remain fresh and have a longer vase life.  The duration that flowers…
