Whitehead broom, also known as shrubby false buttonweed or southern larraflower, is becoming problematic in south Florida pastures, hayfields, and rights-of-way. This 2-page fact sheet discusses a few options to control this species. Written by Brent Sellers and James McWhorter, and published by the UF Agronomy Department, August 2016.
A recent rise in suspected horse poisonings has brought new attention to creeping indigo (Indigofera spicata), a toxic plant which has reportedly been in Florida for as long as 90 years. This new 5-page fact sheet covers plant description, signs of creeping indigo toxicity, and roles of creeping indigo’s toxins, as well as treatment and management. Written by Robert MacKay, Ed Jennings, Brent Sellers, Jason Ferrell, and Amanda House, and published by the UF Department of Agronomy, August 2015.
Smutgrass is a serious weed of improved perennial grass pastures, roadsides, natural areas, and waste areas in Florida. A 2003 survey found that smutgrass was second only to tropical soda apple as the most problematic weed species in Florida pastures, but now that practices to control tropical soda apple have been widely adopted in Florida, smutgrass is likely the most problematic weed species in Florida pastures today. This 4-page fact sheet was written by Brent Sellers, J. A. Ferrell, and N. Rana, and published by the UF Department of Agronomy, January 2015. (Photo Credit: B. Sellers, UF/IFAS)
Heifer development continues to be one of the largest expenses to cow-calf operations, primarily due to cost of feed. Replacement heifers should be bred to calve at 24 months of age in order to maximize lifetime productivity of breeding females. Therefore, heifers should conceive at 15 months of age and achieve puberty at 13–14 months of age because heifers are infertile on the pubertal estrous cycle. This 4-page fact sheet was written by Phillip Lancaster and Cliff Lamb, and published by the UF Department of Animal Sciences, September 2014.
