Electronic logging devices, or ELDs, became mandatory for commercial motor carriers December 18, 2017. The compliance timeline for the produce industry was delayed with two 90-day waivers. On June 18, 2018, however, ELDs became mandatory for produce haulers as well. The primary purpose behind requiring ELDs was to ensure greater compliance with existing hours of service requirements by motor carriers and their drivers. This 5-page fact sheet written by Fritz Roka, Tara Wade, and Craig Sprouse and published by the UF/IFAS Food and Resource Economics Department reviews HOS rules, clarifies agricultural exceptions to the HOS rules, and offers a preliminary discussion as to how ELDs could affect south Florida produce growers.

Process of Drying Post-Harvest Hops (Humulus lupulus) for Small-Scale Producers Using a Novel Drying Rig

Fresh horticultural goods often require drying post-harvest to preserve quality and allow for successful long-term storage of plant material. Given the influx of hops cultivation in the state of Florida, this 5-page publication will help Florida hops growers and hobby brewers to understand how to efficiently dry hops prior to storage. Written by Sean Campbell and Brian Pearson and published by the UF/IFAS Environmental Horticulture Department, January 2019.

The Economics of Planting New Citrus Groves in Florida in the Era of HLB

Citrus greening, or huanglongbing (HLB), is a bacterial disease that affects citrus trees’ vascular systems, limiting nutrient uptake. As trees become increasingly affected by the disease, they suffer premature fruit drop, the fruit harvested is smaller and misshapen, and the juice quality is compromised, all resulting in lower yield. To this date there is no cure or successful management strategy to deal with HLB. This 8-page fact sheet written by Ariel Singerman, Marina Burani-Arouca, and Stephen H. Futch and published by the UF/IFAS Food and Resource Economics Department summarizes the results of an analysis of three tree densities under different production and market conditions to determine which density is most profitable.

Thinning Florida Peaches for Larger Fruit


Fruit size is an important factor in a fruit crop’s marketability. This 6-page document discusses fruit thinning, a process that is critical to achieving larger-sized peaches, and thus is critical to the success of peaches grown in Florida. Written by Yuru Chang, Ali Sarkhosh, Jeffrey Brecht, and Peter Andersen and published by the UF/IFAS Horticultural Sciences Department, January 2018.

Nematodes Parasitizing Hops in Florida

Meloidogyne javanica root gall symptoms on cucumber, UF/

The growth of Florida’s craft beer industry has created new opportunities for Florida growers to establish commercial hop (Humulus lupulus) operations. However, many challenges including several nematode species make the establishment of this industry difficult. This 4-page fact sheet written by Johan Desaeger and published by the UF/IFAS Department of Entomology and Nematology describes nematodes that prey on hops and suggests some strategies for preventing nematode damage to safeguard this emerging industry.

Applications of Artificial Intelligence for Precision Agriculture

Real-time citrus detection using YOLO (a real-time AI object detection algorithm) on an NVidia Jetson TX2 board (Graphics Processing Unit, GPU). These results are achieved by using just 150 pictures to train the AI-based system.

Technological advances in computer vision, mechatronics, artificial intelligence, and machine learning have enabled the development and implementation of remote sensing technologies for plant, weed, pest, and disease identification and management. They provide a unique opportunity for the development of intelligent agricultural systems for precision applications. This 5-page document discusses the concepts of artificial intelligence (AI) and machine learning and presents several examples to demonstrate the application of AI in agriculture. Written by Yiannis Ampatzidis, and published by the UF/IFAS Department of Agricultural and Biological Engineering, December 2018.

Yield and Horticultural Performance of Naked-Seed Pumpkin in South Florida

Pumpkin seeds with a thin or soft seed coat are called naked seeds, and are a popular ingredient in many snacks, breads, breakfast cereals, soups, and other edible goods. This 5-page document reports on yield and horticultural performance of two naked-seed pumpkin cultivars under south Florida spring growing conditions. Written by Geoffrey Meru and Yuqing Fu and published by the UF/IFAS Horticultural Sciences Department, December 2018.
