Hand Pruning and Training of Tropical and Subtropical Fruit Trees

This new 6-page document explains the proper way to prune fruit trees using hand tools. An important aspect of growing tropical and subtropical fruit trees is size control through pruning. In addition to size control, pruning also makes it easier to spray the tree and harvest fruit from the tree. Pruning also makes the tree more hardy to wind events and healthier in general because you can remove damaged or unhealthy parts of the tree.

What the Agricultural Sector in Florida Needs to Know about Heat-Related Illness (HRI)

Heat-related illness (HRI) can range from rashes, fainting, and cramps to heat exhaustion and heat stroke. It can be fatal, and all outdoor workers in agriculture (as well as those in high-heat indoor settings such as greenhouses) are at risk. This new 6-page publication of the UF/IFAS Department of Agricultural Education and Communication provides basic information on how to recognize the symptoms of HRI, on the underlying physiological processes and related risk factors, and on how to treat it. This publication also provides a list of preventative measures that growers, supervisors, and agricultural workers can follow, along with links to additional resources.

Hemp Fertilization: Current Knowledge, Gaps and Efforts in Florida: A 2020 Report

Hemp is an annual herbaceous plant that may be grown for fiber, seed, or flowers. Starting in April 2020, the Florida Department of Agriculture and Consumer Services began accepting applications for cultivation of hemp in Florida, with the potential for building a $20-$30 billion industry in the state. The statewide UF/IFAS Industrial Hemp Pilot Project is researching aspects of agronomic production for hemp cultivation. While a few other state soil testing laboratories provide soil tests and nutrient recommendations based on research and experience, at this time no Florida-specific data on nutrient requirements and fertilization are available. This new 5-page article, written by Rao Mylavarapu, Zachary Brym, Luis Monserrate, and Michael J. Mulvaney and published by the UF/IFAS Department of Soil and Water Sciences, provides a summary of published and personal communications from different states on hemp fertilization.

A Comparison of Planting Techniques for Submerged Aquatic Vegetation

Submerged aquatic vegetation has numerous benefits for aquatic ecosystems, from improving water quality to providing important habitat that supports a diverse food web. This new 6-page publication of the UF/IFAS Department of Soil and Water Sciences describes the breadth of options available to managers who wish to plant SAV at new locations. Because all methods have both benefits and drawbacks, and because all planting locations have different (often unknown) challenges for plant survival, managers may choose to try multiple methods to increase the likelihood for success. Written by Laura Reynolds, Carrie Reinhardt Adams, Enrique Latimer, Charles W. Martin, Christine Rohal, and Jodi Slater.

LED light increases leaf area and root length of Humulus lupulus (var. Tettnanger) in vitro

Propagation of hops has traditionally been accomplished through vegetative techniques. A more modern technique, micropropagation, can be used to propagate hops and offers several advantages to vegetative techniques. Research examining the use of LED lights in plant production has observed its ability to promote growth in plants through emission of higher light quality, such as enhanced red and blue wavelength discharge. This new 5-page EDIS publication provides information on the use and application of LED lights to enhance leaf area and root length of hops. Written by Chi D. Nguyen, Dominic Vu, Heqiang Huo, and Brian Pearson, and published by the UF/IFAS Environmental Horticulture Department.

Aquaculture applications of the Family Blenniidae

Marine ornamental fish production is still in its infancy compared with its freshwater counterpart. About 1,800 wild-caught fish species are imported into the United States each year, clear proof of the need for the expansion of marine ornamental production to include new species and families of fish. Distinct behavior and a wide range of colors makes fish from the Blenniidae family, called blennies, a popular choice in the aquarium hobby. These hardy fish are small and rarely aggressive to other reef species and they eat algae and clean tank substrate. This 6-page fact sheet written by Jesse Von Linden, Joshua T. Patterson, Cortney L. Ohs, and Matthew A. DiMaggio and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation provides a brief overview of the family including description and taxonomy, natural history, culture techniques, a bit about disease challenges, and advice on marketing for ornamental Blennids.

Aquaculture Applications of the Family Gobiidae

Marine ornamental fish production is still in its infancy compared with its freshwater counterpart. About 1,800 wild-caught fish species are imported into the United States each year, clear proof of the need for the expansion of marine ornamental production to include new species and families of fish. The family Gobiidae is the fourth most imported family of marine ornamental fish. Gobies can be easily housed with a variety of other species of fish. Several have qualities that lend themselves to aquarium life. Some clean other fish and others sift the sand bed. Many naturally perch on the rockscape or corals, spending their time beautifying their surroundings with their bright colors and intriguing behavior. This 7-page fact sheet written by Jesse Von Linden, Joshua T. Patterson, Cortney L. Ohs, and Matthew A. DiMaggio and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation provides a brief overview of the family including description and taxonomy, natural history, culture techniques, a bit about disease challenges, and advice on marketing for ornamental Gobids.

Overview of Commonly Cultured Marine Ornamental Fish

A close-up photo of a rainbow-colored fish, predominantly green but with orange, red, teal, and yellow stripes and blotches. It's about 2.5 inches long and lying on one side in a man's palm.

The production of freshwater ornamental fish dominates the ornamental aquaculture industry, yet the small marine ornamentals sector has grown substantially in recent years. This 7-page fact sheet written by Elizabeth M. Groover, Matthew A. DiMaggio, and Eric J. Cassiano and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation briefly reviews the more common groups of marine ornamental fishes cultured in the United States. As we learn more about marine ornamentals and as aquaculture protocols for marine ornamentals develop and improve, it is possible that more species may become economically feasible to produce and more cultured marine fish may begin to supplement wild-caught stocks in the marine aquarium trade.
