Horses are uniquely sensitive to fumonisin and ionophores compared to other livestock species. Facilities, particularly mixed-species feed facilities, need to ensure CGMPs, SOPs, and possibly preventive controls are implemented to address those concerns in addition to more general hazards. This 5-page fact sheet discusses common biological, chemical, and physical hazards in horse feeds as well as methods of prevention. Written by Jason M. Scheffler, Taylor N. Langford, Carissa Wickens, and Lori Warren, and published by the UF/IFAS Department of Animal Sciences, June 2018.

Seed Piece Spacing Adjustment for Florida Chipping Potato

Seed spacing directly affects crop revenue because the number of potato seeds planted determines the final plant population density. The analysis presented in this 5-page publication was extracted from a series of field trials that looked at improved potato plant arrangement in the field by adjusting seed piece spacing for Florida growing conditions.

Frost Damage of Carinata Grown in the Southeastern US

More severe cold damage of carinata during early bolting. This level of damage is expected to reduce stands and yield. Note that aboveground tissue was severely affected, but neither the growing points nor roots died. This field generally grew back from the growing point, but could have resprouted at the crown if the damage was more severe. UF/IFAS West Florida Research and Education Center, Jay, FL.

Brassica carinata is an annual oilseed crop used for the commercial production of jet fuel. One of the challenges to commercialization of this crop in the southeastern United States has been frost damage. This 4-page fact sheet discusses symptomology and ways to minimize risk of frost damage to carinata. Written by Michael J. Mulvaney, Ramdeo Seepaul, Ian Small, David Wright, Silvana Paula-Moraes, Carl Crozier, Paul Cockson, Brian Whipker, and Ramon Leon, and published by the UF/IFAS Agronomy Department, May 2018.

Florida Crop/Pest Profile: Sugarcane

Sugarcane field in Belle Glade, Florida.

Sugarcane (Saccharum interspecific hybrids) is the main source of sugar in the world. It is grown in more than 90 countries in tropical and subtropical regions. Cultivation techniques and production challenges vary by location (Rott 2017; Rott 2018). This 19-page document discusses characteristics of the sugarcane crop and pests affecting its production in Florida, which is the largest producer of sugarcane in the United States. Written by P. Rott, D. C. Odero, J. M. Beuzelin, R. N. Raid, M. VanWeelden, S. Swanson, and M. Mossler, and published by the UF/IFAS Agronomy Department, revised May 2018.

This 3-page fact sheet written by Byron Love, Michael Andreu, and Chris Demers and published by the UF/IFAS School of Forest Resources and Conservation summarizes a study to determine whether landowners may gain increased economic returns if they mark the first thinning in a southern pine stand. The study found that marking can indeed bring higher revenue at final harvest. The greater number of high-quality and faster-growing trees remaining after a marked thinning is the main reason for immediate and future increases in value.

Brunswickgrass or Paspalum nicorae: A Weed Contaminant in Southern Pastures and Bahiagrass Seed Production Fields

Closely grazed bahiagrass pasture with patches of brunswickgrass in late September (toward the end of the growing season) in Levy County, FL.

Brunswickgrass (Paspalum nicorae Parodi) is becoming a problematic weed in summer perennial grass pastures in the Southeast. The plant is competitive with bahiagrass
and bermudagrass. Since it is less palatable, it can eventually dominate a perennial grass pasture. Brunswickgrass has become naturalized and has reportedly contaminated bahiagrass seed fields and pastures in the southeastern states, including some of the important counties for seed production in Florida, such as Gilchrist, Levy, Alachua, Citrus, and Sumter. This 4-page fact sheet provides an overview of brunswickgrass and discusses its appearance, variety/germplasm, and management.

The Immigration and Nationality Act (INA) of 1952 authorized a nonimmigrant visa category, known as H-2, for foreign agricultural and nonagricultural workers to come to the United States and perform temporary services. To protect against disruptions in the farm labor supply, many growers are turning to the H-2A program to import foreign guest workers. This 5-page fact sheet written by Berdikul Qushim, Zhengfei Guan, and Fritz M. Roka and published by the UF/IFAS Food and Resource Economics Department explains the H-2A program and briefly discusses immigration reform.

The US Tomato Industry: An Overview of Production and Trade

A bin of cherry tomatoes UF/IFAS Photo by Amy Stuart
Tomatoes are one of the world's most consumed vegetable crops. In the United States, domestic production meets about 40% of the total domestic demand for fresh-market tomatoes, with the rest of the demand met by imports, mostly from Mexico and Canada. Since 2000, however, fresh tomato production in the United States has exhibited a steady declining trend. One major reason is the increased competition from Mexico. This 4-page fact sheet written by Zhengfei guan, Trina Biswas, and Feng Wu and published by the UF/IFAS Food and Resource Economics Department argues for US government measures to help the domestic tomato industry resolve labor shortages and encourage research and development of labor-saving technologies such as mechanical harvesting to make the US tomato industry more competitive and sustainable.

Labor Requirements and Costs for Harvesting Tomatoes

Biological Scientist, Brian Sidoti, arranges tomatoes harvested from tests at  the University of Florida's Gulf Coast Research and Education Center in Bradenton.

Florida accounts for 30% to 40% of all commercially produced fresh-market tomatoes in the United States. Almost every southern county in the state grows tomatoes. This 4-page fact sheet written by Zhengfei Guan, Feng Wu, and Steven Sargent and published by the UF/IFAS Food and Resource Economics Department presents the results of a 2015 study that examined the time it takes to harvest this important crop.

Tomato Suspension Agreements and the Effects on Market Prices and Farm Revenue

Freshly picked tomatoes.
The production capacity of the US tomato industry has decreased significantly in the past decade. The US Department of Commerce and the Mexican tomato industry negotiated and signed several Suspension Agreements that set floor prices for imported Mexican fresh tomatoes to protect the US domestic industry. This 4-page article written by Zhengfei Guan, Dong Hee Suh, and Feng Wu and published by the UF/IFAS Food and Resource Economics Department provides a review of the history of the suspension agreements and an analysis of their effects on the US tomato industry.

Degree-Days: Growing, Heating, and Cooling

Corn stalks growing in a field

How much and when it rains, freezes, and thaws can make the difference between boom and bust for a year's crop. However, temperature can predict more than boom or bust. Atmospheric temperature can predict the growth rates of many plants. For this reason, growers use a concept called growing degree-days (GDD), sometimes called heat units. This 5-page document discusses growing degree-days, use of the AgroClimate website to track and forecast GDD accumulation, heating and cooling degree-days, and methods for calculating HDD, CDD, and GDD. Written by Clyde W. Fraisse and Silvana V. Paula-Moraes, and published by the UF/IFAS Department of Agricultural and Biological Engineering, revised December 2010 and April 2018.

Donn Shilling and Eldridge Wynn look over a research field

Cogongrass (Imperata cylindrica (L.) Beauv.) is a Southeast Asian warm-season perennial grass species that has spread to all continents except Antarctica. It is considered among the worst problematic weeds on a global scale. Control of cogongrass is difficult, especially in forests. This 6-page fact sheet written by Patrick J. Minogue, Brent V. Brodbeck, and James H. Miller and published by the UF/IFAS School of Forest Resources and Conservation presents recommendations for control strategies that will work in mixed pine-hardwood forests and pine forests.
