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.

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.

New exotic diseases (citrus canker, HLB, and citrus black spot) have sharply increased the real cost of production of citrus in Florida. Growers have been applying different management strategies, and more effective treatments are being researched. The costs and benefits of these alternatives will need to be quantified to establish their economic feasibility. This 5-page fact sheet written by Ariel Singerman and Marina Burani-Arouca and published by the Food and Resource Economics Department focuses on the costs of managing exotic citrus diseases as they become endemic or established within a citrus industry, with Florida used as an example. The steep increase in the real cost of production of citrus in Florida from 2003/04 to 2014/15 provides evidence that managing endemic exotic diseases is very costly for growers, even without taking into account the effect those diseases have on yields. Therefore, governmental policies focused on preventing the introduction of additional exotic diseases would be highly beneficial for citrus growers and the Florida citrus industry as a whole.

After many years in development, dicamba will likely be fully approved for use in tolerant cotton varieties for the 2017 growing season. There is great concern that dicamba drift can result in significant losses in nearby sensitive crops. This concern is well-founded because many crops (such as soybean, snap bean, and peanut) are highly sensitive to extremely low doses of dicamba. All precautions must be followed if these new dicamba formulations are to be used. This 3-page fact sheet discusses herbicide selection, discontinued use of ammonium sulfate, nozzle selection, boom height, and wind speed. It also addresses a few frequently asked questions. Written by J. Ferrell and R. Leon, and published by the UF Agronomy Department, February 2017.

This 4-page fact sheet written by Ariel Singerman and published by the Department of Food and Resource Economics presents the cost of production per acre for processed oranges in southwest Florida during 2015/16. Thirteen growers participated in the survey and provided annual, per-acre costs by program for a “typical” irrigated, mature grove (10+ years old), including resets. The number of acres managed by their combined operations accounts for approximately 41,000 acres, of an estimated 257,298 acres devoted to oranges in the area, so the sample represents 16% of the acreage devoted to oranges in that region. Typical users of the estimates in this publication include growers, consultants, property appraisers, and researchers.

This 4-page fact sheet written by Ariel Singerman and published by the Department of Food and Resource Economics presents the cost of production per acre for processed oranges in central Florida during 2015/16. Five growers participated in the survey and provided annual, per-acre costs by program for a “typical” irrigated, mature grove (10+ years old), including resets. The number of acres managed by their combined operations accounts for approximately 29,000 acres, of an estimated 137,154 acres devoted to oranges in the area, so the sample represents 21% of the acreage devoted to oranges in that region. Typical users of the estimates in this publication include growers, consultants, property appraisers, and researchers.

According to the Foreign Agricultural Service of the United States Department of Agriculture, worldwide consumption of fresh grapefruit in 2014/15 increased from 4.2 million to 5.2 million metric tons. China, which is the largest producer of grapefruit, was largely responsible for the increase. In South Korea, however, the state of Florida in the United States has traditionally dominated the grapefruit market. The South Korean grapefruit market has been increasing in recent years and is expected to keep growing. The industry in Florida now faces fierce competition from other suppliers with lower import prices and different harvest seasons. This 5-page fact sheet written by Yan Heng, Hyeyoung Kim, and Lisa House and published by the Food and Resource Economics Department aims to provide an overview of the grapefruit market in South Korea and evaluate the potential of this market for Florida fresh grapefruit producers.

Trueperella is a harmless bacterium in intestinal tracts of ruminants like deer, cattle, and pigs, but if it migrates out of the intestine to other areas of an animal’s body and proliferates, it can make the animal sick. Trueperella causes many problems in deer, including lesions, abscesses, and pneumonia, and it is one of the types of bacteria that is known to contribute to the disease lumpy jaw. In young fawns, it is a common cause of death. This 3-page fact sheet written by Kathryn D. Pothier, Katherine A. Sayler, and Samantha M. Wisely and published by the Department of Wildlife Ecology and Conservation explains how to spot and treat trueperella, or, better yet, prevent it in the first place.

Insect and mite pests of cotton feed on cotton roots, leaves, stems, and fruit and reduce plant health and productivity, and, subsequently, cotton crop yields. These pests hide in different places on or within the plant or field, which makes them difficult to find and identify and costly to manage. The purpose of this 14-page guide written by Joseph Funderburk, Nicole Casuso, Norman Leppla, and Michael Donahoe and published by the Department of Entomology and Nematology is to provide Florida cotton growers a selected set of options for integrated pest management of insects and mites in cotton fields. It serves as a reference for cultural, mechanical, biological, and chemical control of arthropods. The guide includes links to additional UF/IFAS EDIS articles, as well as external sources of information on arthropod management. The guide also contains a searchable table of registered insecticides, herbicides, and fungicides for Florida cotton.
