Tropical soda apple (TSA), is a serious weed problem in many perennial grass pastures of Florida. Having foliage unpalatable to livestock and highly viable seed, this noxious weed can infest a pasture or native land within 1 to 2 years resulting in lower stocking rates (animals per acre). Geographically, the incidence of this plant in Florida has been highest in the south though it has been observed throughout the entire state and has spread outside of Florida to other southern states. Tropical soda apple has been observed as a weed in pastures, ditch banks, citrus groves, sugar cane fields, vegetable fields, and rangeland. It appears to be restricted to semi-disturbed sites.

This site is made possible by support from the University of Florida Institue of Food and Agricultural Sciences' Cooperative Extension Service and the Florida Department of Agriculture and Consumer Services. Statewide field research is reported as recently and consistently as possible to keep researchers, extension agents, land owners, and other stakeholders informed on TSA-related issues.
