Recommendations for Control and Mitigation of Laurel Wilt and Ambrosia Beetle Vectors in Commercial Avocado Groves in Florida

The lethal laurel wilt epidemic affecting avocado trees in Florida is caused by a fungal pathogen-ambrosia beetle complex (LW-AB). The death of over 120,000 commercial avocado trees in Florida may be attributed to LW-AB. Recommendations for control and mitigation of this epidemic are needed to guide commercial producers in their decision-making process. This new 8-page publication of the UF/IFAS Horticultural Sciences Department outlines the LW-AB epidemic, provides information on the pathogen and ambrosia beetle vectors, provides a brief outline of current research findings, and offers recommendations for the control and mitigation of LW-AB.

Harmonizing the Assessment of the Impacts of Natural Disasters to Florida Agriculture

UF/IFAS Extension has developed an online survey instrument to improve collection of data on losses to Florida agricultural businesses following disasters and to assist agricultural stakeholders in times of disaster. Florida’s agricultural sector frequently experiences substantial adverse impacts during and after natural disasters. Depending on the size and scope of the disaster, agricultural business owners and employees could suffer reduced earnings, financial insecurity, and social stress, and consumers could experience temporary food insecurity. Timely provision of credible estimates of agricultural losses after a disaster is critical to an official disaster declaration and to timely provision of disaster relief and recovery, but collecting data on agricultural losses can present challenges. This 15-page fact sheet written by Christa Court, Alan Hodges, and Matt Lollar and published by the UF/IFAS Food and Resource Economics Department describes the online survey instrument, explains how to use it, and communicates how the data collected will be used in analyses of economic losses.

El higo

El higo (Ficus carica L; familia Moracea) se originó en los trópicos del Viejo Mundo: Asia Menor y la Región Mediterránea. En el Mediterráneo, el higo se ha cultivado desde el año 5,000 a.C. Muchos cultivares de higos fueron importados del Viejo Mundo en los últimos 50 años. Actualmente, sin embargo, no hay programas de mejoramiento de higos en los Estados Unidos, y de entre al menos 60-100 cultivares de higos nombrados, relativamente pocos se cultivan en el sureste de los Estados Unidos.

Tank-Mixing Pesticides without Disasters

Tank-mixing several pesticides is a common practice in conducting pest control. Tank mixes can consist of much more than just pesticides, such as fertilizers, micronutrients, and adjuvants. However, applicators must be aware of potential problems given that there are so many potential combinations when combining these products. Manufacturers cannot possibly test for all of these combinations, so both chemical and physical incompatibility are a concern with the practice. This new 4-page document, written by Frederick M. Fishel and published by the UF/IFAS Pesticide Information Office, describes some common-sense practices to help overcome costly tank-mixing errors.

Bottling, Labeling, and Selling Honey in Florida

Honey producers in Florida have two main avenues for selling their hive products. Larger operations must be properly permitted by the Florida Department of Agriculture and Consumer Services and must bottle honey in a certified food establishment. Smaller-scale honey producers, however, may be exempt from needing these licenses, under Florida’s cottage food laws. This 4-page fact sheet written by Nancy Gentry, James D. Ellis, and Mary Bammer and published by the UF/IFAS Entomology and Nematology Department discusses the laws regarding bottling, labeling, and selling honey in Florida both under and outside of the cottage food laws.

Does Eco-label Format Influence Consumers’ Valuation of Fruit-Producing Plants?

Consumer demand for environmentally friendly products has increased, and consumers are willing to pay more for environmentally friendly fruit-producing plants. With the increased demand, however, the number and variety of eco-labels describing the environmentally friendly qualities of plants has also increased, which could confuse consumers and decrease label effectiveness. Previous studies found that well-designed eco-labels improve consumer understanding, clarity, and choice. This 6-page fact sheet written by Hayk Khachatryan, Alicia Rihn, and Xuan Wei and published by the UF/IFAS Food and Resource Economics Department summarizes a study that addressed how different eco-label formats (text vs. logo) impact consumer visual attention, preferences, and valuations of fruit-producing plants.
