Sorghum-almum is a weak, perennial rhizomatous grass. Leaves of seedlings are rolled in a bud with a fringed membranous ligule. Seedlings often resemble corn seedlings when small. Stems of mature plants are stout and erect, reaching up to 14 feet tall. Leaf blades are flat and sandpapery. Sorghum-almum is commonly found in the southern part of Florida in sugarcane fields and along ditches, canals, and roadsides.

Horse purslane and common purslane are broadleaf weeds associated with sugarcane fields in muck (organic) and mineral soils of South Florida. Growers often confuse these two weed species with each other. However, these two species have distinct phylogenetic (evolutionary) and morphological differences. This 4-page fact sheet was written by Dennis Calvin Odero, Ron Rice, and Les Baucum, and published by the UF Department of Agronomy, January 2013.
Goosegrass is an annual plant that produces a prostrate, mat-like rosette with flattened stems radiating from a central point. It is often described as looking like someone has stepped in the middle of the plant, flattening it out. Because of the whitish to translucent color of the leaf sheath margins, goosegrass usually appears white to silver; this is why it is known as white or silver crabgrass. Goosegrass is found year-round in southern Florida and is commonly associated with newly planted and stubble (ratoon) sugarcane fields. This 3-page fact sheet was written by Dennis Calvin Odero, Ron Rice, and Les Baucum, and published by the UF Department of Agronomy, January 2013.

Florida’s subtropical climate facilitates lettuce production from fall through spring, but the warm, moist conditions are also favorable for insect proliferation and damage. Information about current cultivar response to common insect pests in Florida is limited, so UF/IFAS researchers conducted a study to evaluate cultivar response to insect infestation under field conditions and to identify resistance useful for integrated pest management. This 4-page fact sheet was written by Huangjun Lu, Alan L. Wright, and David Sui, and published by the UF Department of Horticultural Sciences, February 2012.
Although silicon isn’t an essential plant nutrient, adding calcium silicate to soils low in soluble silicon increases yield an average of 20%. This 5-page fact sheet describes calcium silicate recommendations for sugarcane on organic soils, developed using field studies at several locations. Written by J. Mabry McCray, Ronald W. Rice, and Leslie E. Baucum, and published by the UF Department of Agronomy, August 2011. (UF/IFAS Photo: Josh Wickham)
The lesser cornstalk borer attacks a large number of crops, but is a potentially serious pest of sugarcane. But since the populations of this pest vary greatly depending on temperature, UF/IFAS scientists are developing predictive models to predict lesser cornstalk borer population in field. This 4-page fact sheet was written by H.S. Sandhu, L.E. Baucum, and G.S. Nuessly and published by the UF Department of Entomology and Nematology, September 2011.
If rainfall occurs soon after herbicide application, it can affect the effectiveness of postemergence herbicides. And they each differ in their time requirements for rain-free periods following application. This 2-page fact sheet shows rainfast time for postemergence herbicides commonly used in the Everglades Agricultural Area for sugarcane and vegetable production. Written by D.C. Odero and published by the UF Department of Agronomy, August 2011. (Photo by Eric Zamora UF/IFAS)
This 9-page fact sheet provides estimates of costs and returns to produce ethanol from sugarcane, rather than sugar. These preliminary estimates should guide researchers as to whether sugarcane varieties are economically feasible to be considered for biofuel/energy production. Written by José Álvarez and Zane R. Helsel and published by the UF Department of Food and Resource Economics, August 2011. UF/IFAS Photo by Tom Wright.
Energycane is a cross of commercial sugarcane with wild sugarcane. It is higher in fiber and lower in sucrose than commercial sugarcane. This 7-page fact sheet provides estimates of costs and returns to sugarcane farmers and determines whether energycane can provide sufficient economic returns to warrant further research into its use as an energy crop.

This 2-page fact sheet briefly covers the history, symptoms, and epidemiology of this disease of lettuce. Written by D.C. Odero, and published by the UF Department of Agronomy, May 2011.
Faba bean is an important leguminous winter crop in warm temperate and subtropical areas that has been cultivated for more than 10,000 years as a source of protein in human and livestock diets. It is also grown to enhance yields of other crops. Faba bean provides nitrogen in agricultural systems through the unique process of biological fixation of atmospheric nitrogen by symbiosis with Rhizobium bacteria. This substantially reduces the need for nitrogen fertilizers, which contribute to both carbon dioxide and nitrous oxide emissions. This 2-page fact sheet written by D.C. Odero provides weed control recommendations. Published by the UF Department of Agronomy, April 2011.
Essential oils are volatile, aromatic oils obtained from plants and used for fragrance, flavoring, and health and beauty applications.

Pearlstine, and published by the UF Department of Wildlife Ecology and Conservation, April 2011.
This revised 10-page fact sheet features a checklist of bird species that have been found during eight years of surveys in the Everglades Agricultural Area. Most birds can be associated with a specific habitat such as sugarcane, sod, rice or flooded fields and other agricultural and human-inhabited areas. Written by Elise V. Pearlstine and Frank J. Mazzotti, and published by the UF Department of Wildlife Ecology and Conservation, November 2010.
Ragweed parthenium is considered a noxious weed in many parts of the world because of its allelopathic effect on other plants and the health risks it poses to humans. It causes allergic contact dermatitis, rhinitis, and respiratory problems in sensitive humans. Learn more in this 3-page fact sheet was written by D.C. Odero, B.A. Sellers, and J.A.
