2019 Panhandle Fruit and Vegetable Conference: Seeking to Bridge the Agricultural Gap
Join UF/IFAS Extension on October 2 and 3 for the 2019 Panhandle Fruit and Vegetable Conference. Not only will participants get the opportunity to learn about some of the most current innovations in fruit, nut, and vegetable production; marketing and business; and alternative enterprises in the southeast; they will also have the pleasure of hearing the keynote address from Dr. Cary Rivard, an Associate Professor, Extension Specialist, and Director of the Kansas State Research and Extension Center.
The 2019 Panhandle Fruit and Vegetable Conference keynote speaker is Dr. Cary Rivard, an Associate Professor, Extension Specialist, and Director of the Kansas State Research and Extension Center.
Dr. Cary Rivard knows the horticultural and agricultural industries well, as he grew up helping his parents operate a greenhouse business in Kansas City, Missouri. Embracing his family roots, he received his Bachelor of Science degree in agricultural science and biology from Truman State University and his Master of Science and doctorate degrees in plant pathology from North Carolina State University.
But Dr. Rivard knows not everyone gets to grow up witnessing the importance of the agricultural industry firsthand, nor does everyone study agricultural sciences in pursuit of educational degrees. Therefore, throughout Dr. Rivard’s career, he has sought projects that work to connect urban communities with agriculture. As we all know, technological innovations in the 21st century have connected communities in more ways than we could have ever imagined. Yet, it seems a disconnect has arisen among the people in these communities and the food they eat and the farmers who grow that food. But Dr. Rivard sees this disconnect as opportunity. He knows it is agricultural and horticultural leaders – both university specialists and farmers – who can bridge the gap between urban communities and the agricultural products on which they, knowingly or unknowingly, truly rely.
At the Panhandle Fruit and Vegetable Conference, Dr. Rivard will discuss his mission to connect urban communities and agriculture, including his work coordinating the Growing Growers Kansas City program, which provides education to new and experienced growers through farm apprenticeships and an annual workshop series. In addition to speaking as the 2019 Panhandle Fruit and Vegetable Conference keynote speaker, Dr. Rivard will also present one of the conference sessions, where he will discuss his effort to integrate crop diversity and crop rotations into high tunnel production systems.
Register to attend the UF/IFAS Extension 2019 Panhandle Fruit and Vegetable Conference and Post-Conference Tour on Eventbrite (https://panhandlefv2019.eventbrite.com). The main conference will be held on October 2 at the Emerald Coast Convention Center in Fort Walton Beach, Florida. The post-conference tour on October 3 will be a great chance to chat with farmers, and it kicks-off with breakfast at the Emerald Coast Convention Center. Participants will then ride together by bus to tour local farms, enjoy lunch, and be returned to the Convention Center by 3 p.m.

One of the main Florida-Friendly Landscaping principles is to plant the right plant in the right place. In Florida, not only does this apply to the zone you’re in, soils you have, and light conditions in your garden, but also ensuring that invasive, exotic plant species are not used. While most of us have heard about invasive, exotic plants – those that invade and disrupt our unique natural habitats – some may not know where or how to find out which plants are, in fact, invasive and exotic. Some of the more famous invasive, exotic plant species, such as kudzu and hydrilla, are familiar to us and we may have an idea of a plant in our garden that is “aggressive”, but how do we know for sure? Since only a handful of the worst invasive, exotic plants are legally prohibited from being sold, how do we know if a plant we are considering purchasing at our local nursery or another plant already in our gardens is an invasive, exotic? A quick internet search for Florida invasive plants gets you various sources of information. How do you choose which to use?

Fortunately, the researchers at UF/IFAS want you to be able to find the best information in one spot – the UF/IFAS Assessment of Non-Native Plants in Florida’s Natural Areas. This site systematically reviews individual plant species and provides a recommendation as to whether it should be used in North, Central, or South Florida landscapes. Many landscape plants have been reviewed – over 800 – and more are added to the site as reviews are completed. The UF/IFAS Assessment also reviews cultivars of known invasive, exotic plants to ensure that they are sterile and will not revert back to their wild type or hybridize with known invasives, or even closely related native species.
The UF/IFAS Assessment is a simple, convenient source for deciding if a plant should be used in your Florida landscape.
To use the site, simply visit the main web address – assessment.ifas.ufl.edu – and begin typing in your plant name in the search bar. You can begin spelling the scientific or common name and it will start showing possible results as you type. Once you select the plant you’re interested in, it will take you to a new page with photos of the plant, some general information, additional links, and, most importantly, the assessment conclusion for each zone. The conclusion will be one of the following:
- Not considered a problem species at this time,
- Caution, or
- Invasive
Of course, if it’s not a problem, then feel free to use and share that particular plant. If it is a caution plant, then it may be used, but you will want to be extra careful in where you plant it. Those may be better suited as potted plants or planted in areas that are confined, to limit its potential spread. If it’s invasive, don’t plant it.
Caution plants are reassessed every two years while those that are not considered a problem species or are considered invasive are reassessed every ten years.
Another way to use the UF/IFAS Assessment is to filter all reviewed plants by various criteria you’re interested in. If you select assessments on the main page, it will lead you to a list of all reviewed plants. A filter button allows you to choose geographic zone, conclusion type, and growth habit, among some other criteria. This will create a list that can then be exported to a Microsoft Excel table.
As you can see, UF/IFAS is trying to make it easy for you to determine which plants can be used in the landscape without potentially spreading and causing disruption to our unique natural areas.
If you have any questions about individual species that have or have not been assessed, contact your local County Extension Office.

Humans have used animal manures to fertilize food crops for thousands of years. Manures are an organic source of plant nutrients and are often a waste byproduct that must be properly managed when raising animals. Today, many farmers and backyard gardeners continue to use animal manures to provide nutrition to their crops. However, a recent experience at our local extension office brought to our attention the need to know what else, besides nutrients, is in the manure used.
A local backyard gardener brought in samples of tomato plants that had strange new growth. She had purchased the tomato plants, along with other vegetable plants, from a local nursery. When she repotted the tomato plants into larger pots, she added horse manure from her own horses to the soil mix. She then noticed this strange growth on the tomatoes, but not in the other vegetable plants that were repotted without adding horse manure. Herbicide damage was one of the first potential causes we suggested, since the new growth was twisted and distorted, a common symptom of plants that have been sprayed by herbicides. The gardener was sure she had not sprayed any herbicides near these plants, or in the pasture where she keeps her horses.

Photos of the tomato plants were shared with other NW District agents and an agriculture agent with livestock and hay producer experience had the probable answer – herbicide damage due to the horses being fed hay from a hayfield that was treated with a particular herbicide. Interestingly, this agent also had experience with these symptoms after their neighbor had similar issues using manure to fertilize the garden.
Herbicides with the active ingredients picloram or aminopyralid are able to cause this kind of unexpected damage to many gardeners’ crops. Herbicides containing these active ingredients are used in hayfields to control broadleaf weeds. These herbicides are especially effective at controlling hard to manage weeds such as thistle, nightshade, and nettle. They also provide long-lasting weed control. Unfortunately, the persistence of these ingredients extends into the hay, and also persists in the manure and urine of animals who eat hay from treated fields. These ingredients pass through the animal unchanged and remain active as an herbicide. Since many vegetable crops are broadleaf plants, the herbicide’s ingredients cause injury.
So what can a farmer or backyard gardener do to prevent this problem? When purchasing hay for livestock, ask the seller if they know whether the hayfield has been treated with herbicides that contain either picloram or aminopyralid. Most herbicides are known by their common names, rather than their chemical name. If they give you a common name or brand name, the active ingredient can be obtained by contacting your local extension office. If the seller can’t tell you, then, as a precaution, do not use the manure to fertilize broadleaf vegetable crops. The same question should be asked if purchasing hay for mulch as well. Composting the manure or hay does not break down the active ingredient, and may even concentrate it.
While we continue to use animal manures to fertilize our crops as our ancestors did, it’s important to remember that many of the tools and products we use today are much more advanced. These advanced products require that we stay informed of all precautions, use them responsibly, and, in this case, inform end users of any precautions. Remember to always read and follow the label and ask questions. And if a science-based answer is what you’re looking for, your local extension office is a good place to go!
