Profitable sugarcane production in Florida requires effective weed management. Herbicides provide an efficient and cost-effective means of weed control, but excessive use of a single herbicide or group of herbicides with the same mechanism of action has resulted in the development of herbicide-resistant weeds. In crops such as sugarcane where a limited number of herbicides are registered, the loss of a single effective herbicide can be very costly. Thus, it is critical to manage herbicides in order to prevent or delay the development of herbicide-resistant weed populations. This 4-page fact sheet lists herbicides by group number, mechanism of action, chemical family, common name, and trade name. Written by D.C. Odero, B.A. Sellers, J.A. Ferrell, and G.E. MacDonald, and published by the UF Department of Agronomy, October 2014.

Biology and Control of Sorghum-almum in Sugarcane (SSAGR369/SC098)
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. 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.

Biology and Control of Horse Purslane and Common Purslane in Sugarcane (SSAGR368/SC097)
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.

Biology and Control of Goosegrass in Sugarcane (SSAGR367/SC096)
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.

Biology and Control of Coast Cockspur in Sugarcane (SSAGR366/SC095)
Coast cockspur is a relative of barnyardgrass that is native to North America. In South Florida, coast cockspur typically begins to infest sugarcane during the onset of rainfall in late spring. This 2-page fact sheet was written by Dennis Calvin Odero, Ron Rice, and Les Baucum, and published by the UF Department of Agronomy, January 2013.

Fall Panicum: Biology and Control in Sugarcane (SSAGR132/SC079)
Fall panicum (Panicum dichotomiflorum) is a native grass that can be found throughout the United States in agronomic and horticultural crops, turfgrass, nurseries, landscapes, and noncrop areas. It grows well in warm wet conditions and is one of the most common grass weeds found in Florida sugarcane. This 3-page fact sheet provides sugarcane growers with guidance on its identification and control. Written by D.C. Odero, Brent Sellers, Les Baucum, and Curtis Rainbolt, and published by the UF Department of Agronomy, May 2011.
