Biological herbicide. A natural, biological herbicide to control TSA is currently under development and is not available for public use at this time. The product is called SolviNix™ and contains a naturally occurring virus called Tobacco mild green mosaic tobamovirus (TMGMV). Preliminary research has determined that very small quantities of the virus (2 g of active ingredient per acre) provide excellent control of TSA. Two application methods are currently being tested that appear to be practical and user-friendly for both boom spraying and spot-spraying. For additional information on Solvinix, including label and contact information, see the BioProdex, Inc. website: http://bioprodex.com/product.html.

What is a soda apple?
Tropical soda apple is a member of the Solanaceae or nightshade plant family. As young seedlings, TSA has the general appearance similar to horsenettle ( Solanum carolinense ). This can make it more difficult to separate the identity of these two different plants when they are at younger growth stages. Both plants have oak-shaped leaves containing thorns on the stem, stalks, and leaves. As TSA matures, the leaves are broader, contain long yellow-white thorns, and plants grow into much larger, shrub-like plants (Figure 1). TSA can also be distinguished from horsenettle by their creamy white flowers (Figure 3), and immature green and white striped fruit resembling tiny watermelons (Figure 4). When TSA fruit matures these berries containing seed turn yellow.

It occurs in strand swamps, floodplain swamps and scrub brush. In Florida it is found in drained swamp pasture land. TSA is also one of the most endangered plants in Florida right now, due to the number of laws that have been enacted against toxic plants, regardless of their medicinal properties. It start with the Federal Noxious Weed Act of 1974. In some states it is defined legally as being quarantined or having a Class A noxious weed status which means eradication is required by state law, and it is a felony to propagate these plants there. These classifications have been reinforced by Executive Order 13112 signed by President Clinton, and most recently by Public Law 108-412 of October 30, 2004. Due to these short sighted classifications valuable medicinal plant cultivated in South America and India may become an endangered plant in the US because the current Invasive Ecology is only looking at Management practices to remove this plant and not to look at it’s medicinal properties. The plant identification card from the University of Florida, IFAS Division, Center for Aquatic and Invasive Plant Website shows this plant on the Federal Noxious Weed List, and on the Florida Noxious Weed List. It describes the ecological threats associated with this plant includes out competing or crowding native plants which it is a major concern of agriculture as well as a serious threat to Florida natural areas and is a Category I, which means it has been classified as causing ecological damage. The ecological damage associated with TSA includes reducing the livestock carrying capacity, and shading out bahiagrass, another invasive species from South America which is apparently tolerated as it is the basis for most Florida lawns.
