New and Revised Agriculture Publications, March 2017

Here are the new and revised #EDISpubs in the Agriculture program area from March 2017.


Last month we relaased several revisions to our nematode management publications.  Field crop nematologist Dr. Zane Graubau provides management information for cotton, field corn, and soybeans; landscape nematologist Dr. William Crow for golf courses.  Plus the following:


·         Crops: A disease to watch out for in your olive orchard

·         Nursery & Greenhouse: guidance for propagating woody plant cuttings

·         Livestock: Rumen protozoa & using biosolids in forage production

·         Turfgrass: scale insects and mealybugs

·         Food safety: preventing E. coli.






Management of Plant-Parasitic Nematodes in Florida Cotton Production

This 8-page fact sheet written by Zane J. Grabau and published in January 2017 by the UF Department of Entomology and Nematology explains how to diagnose and manage nematode problems in cotton production.

Management of Plant-Parasitic Nematodes in Florida Field Corn Production

This 8-page fact sheet written by Zane J. Grabau and Christopher Vann and published by the Department of Entomology and Nematology explains how corn producers can spot nematode symptoms, sample for nematodes, and manage nematode problems.

Management of Plant-Parasitic Nematodes in Florida Soybean Production

This 8-page fact sheet written by Zane J. Grabau and published by the UF Department of Entomology and Nematology in January 2017 explains how to identify and manage a nematode issue in a soybean operation.

Xylella fastidiosa and Olive Quick Decline: Symptoms and Identification of an Insect Vectored Pathogen

A plant disease called Olive Quick Decline is killing olive trees throughout southern Italy. Although the pathogen that causes the disease is not known in Florida, it may spread to the state, which means that olive producers and homeowners with olives must watch for symptoms of the disease as well as for the leafhopper insects that spread it. This 3-page fact sheet written by Whitney Elmore and Jennifer L. Gillett-Kaufman and published by the Department of Entomology and Nematology explains how to monitor for the disease and its insect vectors and offers advice and assistance for commercial and hobby olive growers.

Nursery & Greenhouse

Does Consumers' Awareness Impact Their Purchase Likelihood of Neonic-Free Plants?

Neonicotinoid (neonic) pesticides have been facing intense scrutiny because of their potential role in pollinator insect population declines. Research has shown that insecticide use in general has resulted in $284 million per year in damages to honeybee and pollinator services in the United States. This is especially worrying because food supply would fail to meet increasing global food demand without pollinator insects.

Consumer awareness of neonic pesticides increases the purchase likelihood for plants that are labeled “neonic-free,” and, as consumer awareness of neonics increases, demand for plants may decrease if there is limited availability of neonic-free options. This 5-page fact sheet written by Hayk Khachatryan and Alicia Rihn and published by the Food and Resource Economics Department explains the practical implications for growers, retailers, and policy makers and describes how these stakeholders can benefit from increased awareness of this important new market niche.

Helpful Details for Commercial Propagation of Woody Plant Stem Cuttings

This three-page fact sheet provides details that are very important for successful propagation of woody plant stem cuttings, such as sanitation, quality of cuttings, the time of year/day to take cuttings, stem size diameter and length of cutting, location of cuts/terminal bud removal, and environmental conditions. Written by Thomas Yeager and published by the Environmental Horticulture Department.


Rumen Protozoa: The Animals within the Cow

As a cow ambles around and eats from the feed bunk, legions of other “animals” are feeding within the cow’s rumen. Billions of protozoa swim about in a single, 20-gallon rumen, colliding with one another while engulfing feed particles and bacteria. These microbes contribute vitally to rumen fermentation and have both positive and negative impacts on animal performance. This 4-page fact sheet discusses classification, activities, removal, and impacts of protozoa. Written by Timothy J. Hackmann, and published by the UF Department of Animal Sciences, January 2017.

Utilization of Biosolids in Forage Production Systems in Florida

This four-page publication provides basic information about land application of biosolids to pastures and hayfields in Florida. The information contained in this document should be of interest to stakeholders, biosolids managers, students, and scientists interested in topics related to biosolids management practices and the potential benefits and risks associated with biosolid land application. Written by Maria L. Silveira, George A. O’Connor, and Joao M.B. Vendramini and published by the Department of Soil and Water Sciences.


Managing Scale Insects and Mealybugs on Turfgrass

This 8-page fact sheet written by Adam Dale and published by the UF Department of Entomology and Nematology in February 2017 describes the types of scale insects and mealybugs that can become pests in turf, explains the damage they do, and lists management techniques to control them.

Nematode Management for Golf Courses in Florida

UF/IFAS is committed to providing the most current information on the notoriously difficult problem of managing nematodes on golf courses. This publication is updated and revised whenever there is a breaking development, to bring you the new information and management advice. Nine pages, revised in January 2017 by William T. Crow and published by the UF Department of Entomology and Nematology.


Food Safety

Preventing Foodborne Illness: E. coli O157:H7

This seven-page fact sheet discusses the common foodborne pathogen E. coli O157:H7, especially as it concerns food handlers, processors and retailers. Written by Keith R. Schneider, Renée Goodrich Schneider, Ploy Kurdmongkoltham, and Bruna Bertoldi and published by the Food Science and Human Nutrition Department.
