Herbicide Resistance Management in Florida Tomato Production

Herbicide resistance was historically not a significant issue in most horticultural crops because few herbicides were applied. Close proximity of agronomic crops and the loss of methyl bromide has led to a gradual increase in herbicide inputs and the increased occurrence of herbicide-resistant weeds in tomato fields. Very few herbicides are registered for tomato, and resistance is a major concern. This new 11-page publication of the UF/IFAS Horticultural Sciences Department provides a definition of herbicide resistance, explains how it develops, and provides management recommendations for tomato growers. It was written for growers and Extension agents, but the information may be of interest to anyone concerned about herbicide resistance in vegetable and small fruit crops. Written by Shaun M. Sharpe, Nathan S. Boyd, Ramdas G. Kanissery, and Peter J. Dittmar.

Facts about Wildlife Diseases: Raccoon-Borne Pathogens of Importance to Humans—The Raccoon Roundworm

Diseases carried by northern raccoons present significant health hazards to both people and pets. This 7-page fact sheet written by Caitlin Jarvis and Mathieu Basille and published by the UF/IFAS Department of Wildlife Ecology and Conservation is part of a series addressing health hazards associated with raccoons. It describes the raccoon roundworm and the disease it causes, baylisascariasis, which normally causes little or no trouble to raccoons but in severe cases can make people and their pets very sick. Sick wild animals can act tame, but do not approach! Contact animal control or a wildlife rehabilitator if an animal seems to be behaving abnormally or if you suspect it is sick.

The Road to Recovery: Building Physical and Emotional Trust when Engaging with Extension Clientele

Now is a crucial time for Extension professionals to engage with clientele. In both urban and rural communities, clients are facing a multitude of unprecedented challenges related to COVID-19. Many Extension professionals already have experience in emergency and disaster preparedness, response, and recovery that can be applied in the present context. However, we must rethink how we interact with and assist clientele to ensure their safety and our own. To do this, it is critical we understand that the pandemic has exacerbated emotional trauma and anxiety resulting in trust gaps. This new 4-page publication of the UF/IFAS Department of Agricultural Education and Communication aims to build Extension professionals’ sensitivity to the needs and emotional strains that COVID-19 presents for clients, and the strategies needed for effective recovery.

Facilitating Community Change: Lessons from Climate Adaptation to Guide Extension Engagement

This 19-page publication written by Martha Monroe and Annie Oxarart and published by the UF/IFAS School of Forest Resources and Conservation provides Extension faculty in Florida with useful strategies to help communities understand, discuss, evaluate, and recommend potential solutions to current and future problems. While much of the research behind these strategies has been conducted in the context of climate adaptations in vulnerable communities and ecosystems, such as coastal fisheries, rainfed agriculture, and floodplain cities, the principles that underlie these processes are universal. The same strategies and guidelines can be tailored for any issue that requires the public to become more informed, generate options, and understand advantages and disadvantages of various choices. In these situations, Extension agents can facilitate a process of thoughtful deliberation to help communities find common ground and move toward finding solutions.

A Simple, Inexpensive, and Portable Image-Based Technique for Nondestructive Leaf Area Measurements

This new 6-page article, part of a series introducing various image-based measurements for horticultural research, introduces a simple, inexpensive, and portable image-based technique for nondestructive leaf area measurements. It uses an imaging apparatus made with ordinary office supplies to obtain leaf images in greenhouse or field environments. Leaf images are then processed and analyzed to measure leaf area using ImageJ, an open-source image processing program. Because both image capture and analysis are performed nondestructively, leaf area can be measured on the same leaf repeatedly, enabling the monitoring of leaf growth over time, as well as photosynthesis and transpiration. This technique is particularly useful to researchers and students studying leaf growth and physiology in greenhouse or field environments. Written by Shinsuke Agehara, Lillian Pride, Mariel Gallardo, and Jose Hernandez-Monterroza, and published by the UF/IFAS Horticultural Sciences Department.
