is solanum viarum poisonous

Degradation of the fruit coat and subsequent release of seed on the soil surface takes about 2 months. Prior to control efforts, tropical soda apple commonly occurred in monocultures of 50 acres (20 ha) or more in Florida [70,85]. The participation rates for each approached varied regionally . Fire Regime Table Medal, J. C., Bustamante, N., Overholt, W., Díaz, R., Stansly, P., Roda, A., Amalin, D., Hibbard, K., Gaskalla, R., Sellers, B., Hight, S., and Cuda, J. 2008). Weed Technology 18: 1120-1124. An unpublished study (Wahaj and others cited in ) suggested that solasodine, a poisonous substance found in Solanum spp. 1998). Seed production may be less in other parts of the world. Information pertaining to tropical soda apple's preferred substrate is limited. Diaz, R., Overholt, W. A., Samayoa, A., Sosa, F., Cordeau, D., and Medal, J. In Mississippi, 10% to 18% of tropical soda apple seed buried in a field and exposed to cold winter temperatures germinated and emerged when moved to the greenhouse the following Beetles showed a dispersal ability of approximately 1 mile per year during the evaluation period. This information is taken from the, Incorporate cost of weed prevention and management into fire rehabilitation plans, Include weed prevention education in fire training, Minimize soil disturbance and vegetation removal during fire suppression and rehabilitation activities, Minimize the use of retardants containing nitrogen and phosphorus, Avoid areas dominated by high priority invasive plants when locating firelines, monitoring camps, staging areas, and helibases, Clean equipment and vehicles prior to entering burned areas, Regulate or prevent human and livestock entry into burned areas until desirable site vegetation has recovered sufficiently to resist invasion by Mullahey, J. Jeffrey. Am. Gainesville, Florida, USAFlorida Department of Agriculture and Consumer Services-DPI, Julio Medal, University of Florida. Tallahassee, FL. Upper and lower bounds for regional cost estimates were then calculated for a 95% level of confidence. does not preclude livestock and wildlife from eating tropical soda apple fruit [68]. An aqueous liquid concentrate of TMGMV named SolviNix LC (Solvi from Solanum viarum and Nix meaning to put a stop to) has been extensively field-tested in Florida since 2000, including under an Experimental Use Permit granted by the EPA and approved by the State of Florida. Because tropical soda apple is commonly dispersed by wildlife, sites where wildlife congregate—such as oak hammocks, 1996, 1997, Akanda et al. University of South Florida, Tampa, FL. 27. 1998). 2010. The Florida Cattleman and Livestock Journal 69 (8):40-41. To date, little has been published about TSA’s plant associations in the other states. In southwestern Florida, growth and nutrient accumulation were compared between tropical soda apple plants in a pasture and a hammock. Assuming that beetles arrived at survey sites from the nearest release site, the average distance beetles traveled per year since their release was about 3 miles. This plant belongs to the Solanaceae, a family that includes very important economical crops such as eggplant, tomato, potato, tobacco, pepper, and approximately thirty native Solanum spp. Hypersensitive necrotic lesions elicited by TMGMV in an inoculated TSA leaf. The term "soda apple" probably derives from "Sodom apple", modified due to the fruit's detergent properties. 2008. University of Florida-IFAS E-mail: sellersb@ufl.edu; E-mail: jferrell@ufl.edu. epigeal [69]. Schematic representation of the phenology of Gratiana boliviana in Florida. In addition, Cooke (1997) estimated another $2 million in economic losses due to heat stress as cattle are denied access to shaded areas crowded with TSA. Medal, J. C., Bustamante, N., Bredow, E., Pedrosa, H., Overholt, W., Díaz, R., and Cuda, J. When the beetles arrive at the release site most of the beetles will be either clustered on the top of the container clinging to the screen or down below clinging to the leaves. Only two hosts are of concern: peppers (Capsicum spp.) The authors, however, did not indicate how this treatment could In India, it is considered a "woody" herb [80]. Since TSA seed germinate continually from October to May (Mislevy et al. SIDA 15(4): 605-61. However, development and reproduction of L. texana on the non-native turkey berry were comparable with silverleaf nightshade. 1998. 1983), and belongs to the same subgenus Leptostemonum (D’Arcy 1972, Nee 1991). The number of TSA fruit produced per beetle-defoliated plant significantly decreased , with none or very few small fruits produced compared with the large number of fruits observed during the summer of 2003 at the time the beetles were released (Figure 2). greenhouse, increases in phosphorus increased tropical soda apple plant height and fruit production [17]. for considerations on the use of herbicides in wildlands and detailed information on specific chemicals. It is unknown whether tropical soda apple survives or establishes after fire in mesic flatwoods or if it establishes on these sites in the absence of fire. As they become acclimated to the area they will move out to TSA in sunny areas. 27. Germination may be stimulated [88] or percent germination increased (Vincente 1972 cited in [70]) with alternating temperatures. The most common control measure in all three regions of Florida was chemical control. Tropical soda apple can be expected to occur in other subtropical areas as well. 85(1):254-260. Mullahey, J.J., Cornell, J.A. These new controls that are now available have helped mitigate the impact of TSA on agriculture and in natural areas making regulation less challenging and ultimately making this unwanted invader a less onerous weed pest. Therefore, triclopyr became the herbicide standard for TSA control throughout Florida. Tropical Soda Apple International Collaborators: Robinson A. Pitelli, Aldo Santana, Renán Gravena (Universidade Estadual Paulista, Jaboticabal, São Paulo, Brazil); J. Henrique Pedrosa, Edgard Bredow (Universidade Federal do Curitiba, Brazil); Marcelo Vitorino, André Busss, Liliam Beal (Universidade de Santa Catarina, Blumenau, Brazil); Charles Wikler (Universidade do Centrol-Oeste, Iratí, Paraná, Brazil); Robert Barreto (Universidade de Viçosa, Minas Gerais, Brazil); late Daniel Gandolfo, Fernando MacKay (USDA-ARS, Hurlingham, Buenos Aires, Argentina); Diana Ohashi (INTA-Cerro Azul, Misiones Province, Argentina); Bolivar Garcete (Museo de Entomología, Asuncion, Paraguay); Terence Olckers (Plant Protection Research Institute, Hilton, South-Africa). Perhaps the stress of beetle feeding reduced the ability of the plants from regenerating from roots. Cattle producers were willing to increase production cost by controlling TSA to maintain their constant herd size. The host-specific lethal hypersensitive response causes the plant to self-destruct even as the virus titer remains relatively low in TSA tissues. The population in Pennsylvania arrived in the summer of 1996 (Lingenfelter and Curran 1998) but did not become established (PISC 2011). In places that experience FDACS-DPI, Gainesville, FL. Habitat Types and Plant Communities), Solanum khasianum Clarke, a crop for production of Solasadine. U.S. Patent No. On average, surface fires occur every 2 years and stand-replacing fires every 65 years. We hypothesized that ingestion of S. viarum … The seeds are lens-shaped [102] and about 2 mm long [108]. Seed can remain dormant for months, if not years. Eggs are brown and enclosed in a membranous envelope, larvae are spiny and pale green, pupae are spiny, flattened and immobile, and adults are about 1/4″ long and nearly as wide, and a deep green color. Tallahassee, FL. Plant Viruses Online, 2011. TSA typically invades improved pastures, where it reduces livestock carrying capacity. Geographically, the incidence of this plant in Florida has been highest in the southern part of the Florida peninsula though it occurs throughout the entire state and is present in Alabama, Georgia, Mississippi, South Carolina, Tennessee, Texas, Louisiana, and Puerto Rico. In contrast, TSA bloom and fruit production in other southern states is limited by frost. The timing of diapause allows the syncronization of insect herbivores with the phenology of their host plant. Since its release in 2003, G. boliviana has spread as far north as Rhea County, Tennessee, at 35.6 ° N latitude [31]. Leaves are pubescent (contain hairs), 4 to 8 in long and 2 to 6 in wide, and are moderately to deeply divided into broad pointed lobes (Wunderlin et al. Boyd, J.W., Murray, D. S., and Tyril R. J. It can be applied with a backpack sprayer delivering the virus at 80 to 200 psi, certain types of commercially available herbicide wipers, and a wet-blade mover. that are considered susceptible to TMGMV include susceptible, resistant, and immune varieties. Some states, such as Georgia, have stopped wide-scale herbicide applications due to funding restrictions, while other states, such as Alabama, have continued a vigorous herbicide campaign and are now looking at ways to reduce the weed in areas difficult to spray. In the greenhouse, tropical soda apple seed planted about 0.4 inch (1 cm) deep germinated, grew to a height of about 8 inches (20 cm), and had an average of 20 leaves within 60 days after planting. Virus activity in soil is greatly reduced when soil pH changes from 7.0 to 4.9. researchers had released a South American beetle for biological control for tropical soda apple, and other South American insects were being evaluated [58]. Other states: An environment-friendly, natural, “green” herbicide, SolviNix is expected to be approved for use in organic beef and milk production. Seed production may be stopped if herbicide is applied prior to tropical soda apple flowering [1]. After 6 days any consumed seeds that are passed are no longer viable. Alternate, 4 to 8 inches (10 to 20 cm) long and 2 to 6 inches (5 to 15 cm) wide. Researchers, mostly affiliated with the University of Florida, have been studying a variety of insects, fungi, bacteria, and viruses for their potential to control tropical soda apple. Costs are simply the amounts paid or charged for something and would include the costs of TSA control. FEIS home page under "Find Fire Regimes". On Nov 25, 2004, caron from Woodland Park, CO (Zone 4b) wrote: U.S. Since then, the weed had rapidly spread to one million acres of pasture land, sod farms forests, ditches and other natural locales. least 1 week prior shipping are less likely to spread tropical soda apple seed through their feces [10]. Gratiana boliviana has four developmental stages (egg, larva, pupa, adult) (Figure 1). In J.G. This can be accomplished through early detection and eradication of new infestations, careful monitoring and follow-up, and limiting dispersal of its seed on burned sites. However, as indicated earlier, the beetle has not been able to establish in north Florida, or southern parts of Georgia and Alabama. Edited by: Julio Medal, William Overholt, Raghavan Charudattan, Jeff Mullahey, Richard Gaskalla, Rodrigo Díaz, James Cuda, University of Florida-IFAS. Game animals like deer and feral hogs will consume the fruit and Sandhill Cranes have been observed to eat the seed from within the fruit. Description. Invasive Plants. The regional economic impact of TSA was estimated as a function of the total regional pastureland, the TSA infestation rate, the proportion of ranchers attempting to control TSA, and the cost of TSA control. Economics of Tropical Soda Apple in Florida, III. In J. J. Mullahey (ed.). Florida Entomologist 93 (4): 493-500. Mislevey et al. Proc. The infested area increased to more than 303,000 ha in 1995 (Mullahey 1996, Mullahey et al. The fruit are sweet and cattle will smell and seek them out, spreading viable seed in their manure for up to 6 days after consuming the fruit. . The economic effects of tropical soda apple (TSA), or for that matter any invasive exotic species, can be measured at several different levels and the appropriate level often depends on the goal of the analyst. An integrated approach including all the management tactics available should be utilized to successfully suppress TSA at a reasonable cost. In the laboratory, seed viability and germination rates were high for tropical soda apple seed sown under variable conditions. E-mail: jcuda@ufl.edu. Tropical soda apple occasionally occurs in mesic flatwoods, which are of interest from a fire perspective. Our research has shown that Milestone and Forefront will control germinating seedlings for over 6 months after application. An interpolated surface of beetle density indicates highest densities along a band running from approximately Naples on the west coast to Fort Pierce on the east coast, with a few areas of high density further north (Figure 6). Royal Soc. was released in Jasper County, Texas, to control tropical soda apple [48,97]. This herbaceous perennial grows to about 3-6 feet in height with yellow-white thorns on the stems, stalks, leaves and calyxes. Cattle and wildlife spread TSA by consuming the fruit and spreading the seed via feces. Fruit is a poisonous globose berry, 0.8-1.2 inch wide, green with darker veins like … In other words, these bounds on cost are the statistical estimate of the direct loss to cattle ranchers due to TSA invasion (Table 5). 1985 (accidental)2. By 2007, many of the small infestations of tropical soda apple had been eliminated in Mississippi [11], so its spread may be on the decline in that state. Silverleaf nightshade, Solanum elaeagnifolium Cav., a close relative of the three aforementioned invasive Solanums, is native to the southern United States, Mexico and possibly Argentina (Goeden 1971, Boyd et al. Botany Circ. Fruit size may be a better determinant of seed maturity than Dense stands of TSA have appeared after the soil has been disturbed through clear cutting TSA infested wood lots and introducing livestock. Waterhouse, D. F., and Norris, K. R. 1987. Diaz, R., Overholt, W.A., Samayoa, A., Sosa, F., Cordeau, D. and Medal, J. harvested from TSA infested locations, can be contaminated and may have moved the weed to new areas. Tropical soda Royal Botanic Gardens Kew. Wunderlin, R.P., Hansen, B. F., Delaney, K. R., Nee, M., and Mullahey, J. J. Tropical soda apple (TSA), Solanum viarum Dunal, is one of three non-native species of the genus Solanum that are considered invasive weeds of agricultural and natural areas in Florida (Langeland et al. “The economic impact of tropical soda apple on cattle production in Florida.” Unpublished manuscript, Agribusiness Program, College of Engineering Sciences, Technology and Agriculture, Florida A&M University, Tallahassee, Florida. It is a poisonous nightshade species from Africa and not related to true apples. In Florida, tropical soda apple flowers and produces fruit throughout the year [2,70], but both events may be more concentrated during certain times. With continued TSA spread and the absence of alternative effective control measures, it is likely that the demand for these herbicides will continue to grow and this might have negative impact on the environment. The TSA seed is spread by cattle, wildlife, contaminated hay, grass seed, sod and moving water. One of the more common forms of economic analyses is that of comparing a mitigation action’s potential benefits and costs. Two of the most damaging insect herbivores are the defoliating beetles Leptinotarsa defecta (Stål) and L. texana (Schaeffer) (Coleoptera: Chrysomelidae) (Jacques 1988). fruit ripeness. Neck, R.W. Germination may be enhanced by scarification and may be sensitive to changes in temperature, light, pH, moisture availability, and fruit ripeness. Seed overwintering on the soil surface may Fires may be more frequent on the upper slopes rather than low to midslopes of hammocks and may play an important role in the formation and maintenance of xeric hammocks (review by [81]). Eight years after its introduction to North America, tropical soda apple was reported in 20 natural areas from as far north as Alachua County, Florida (Florida EPPC 1996 cited in [52]). Royal Botanic Gardens, Kew, United Kingdom. 2002, Medal et al. Ranchers estimated their cost to control TSA on an acre basis, with the average cost for north Florida ranchers approximately a third higher than central and south ranchers. Although tropical soda apple has not been studied for its potential to alter fire regimes in wildlands, it may alter fuel characteristics and impact fire regimes, especially where it dominates the plant community. To determine the extended economic impact or ripple effect of TSA control through the economy at large, the total expenditures associated with TSA control needed to be determined. 7:783-786. I. ), Solanaceae III: Taxonomy, chemistry, evolution. sites [85], suggesting it may be intolerant of deep shade. The spread of tropical soda apple within Florida and to other southeastern states has been facilitated by movement of cattle, pasture grasses, and composted manure from infested areas [71,108]. After evaluating G. boliviana's generational turnaround and tolerance to cold, Diaz [31] concluded that the northern extent of this beetle's range in the United States would be near 32 to 33 ° N latitude. Stephen.Hight@ars.usda.gov Daniel Flores. Center for Aquatic and Invasive Plants Palatability and/or nutritional value), See the In the laboratory, tropical soda apple seed germinated in 6 to 7 days (Mullahey unpublished data cited in [69]). Gratiana boliviana adults: A) reproductive dorsal B) reproductive ventral, C) diapause dorsal, D) diapause ventral. biflora), slash pine (Pinus elliottii), red maple (Acer rubrum), and wax-myrtle (Myrica cerifera). The most preferred methods of TSA control were chemical herbicides and mowing (Table 4). Patol. ), Proceedings of the VII International Symposium on Biological Control of Weeds, 6-11 March 1988, Rome, Italy. ), Veronica Manrique, University of Florida–REC, Fort Pierce, FL. Hammocks: Fort Pierce, FL. More recently, however, dense stands of TSA are less common, but the total land area infested likely remains the same. This article will examine much of the work that has been done with herbicides since TSA was first identified in south Florida. Physical or mechanical control: Other researchers in Florida reported that 4% to 16% of tropical soda apple seed was dormant. The fact that TSA can grow into dense stands, and even render entire pastures unusable for grazing, has had a significant economic impact on Florida’s cattle producers (Salaudeen 2006). In Florida, tropical soda apple occurs in somewhat poorly drained [108], sandy soils [12,36,61]. Germination), cyme [108]. TMGMV is a pathogen principally of plants in the Solanaceae because the majority of the TMGMV-susceptible plants are in this family while a few are in other unrelated families. Eight to 10 tropical soda apple plants in Mississippi have the potential to produce 1 million seeds annually [24]. Wunderlin, R. P.and Hansen, B. In E.S. Although scarified tropical soda apple seed germinated more quickly than unscarfied seed, percent germination was The root system of tropical soda apple can be extensive. Scientific advances in the analysis of direct risks of weed biological control agents to nontarget plants. As of this writing (2009), it was uncertain what happens to tropical soda apple seeds that are not dispersed by animals or equipment. Several natural enemies of G. boliviana have been identified in Florida, but there is no information on the distribution and impact of these enemies on the population of the beetle. This plant spreads almost entirely from seeds and therefore it is a high priority to control seed production, “Dead plants don’t produce seeds”. Biocontrol 47:445-461. 1972. Thus, the use of TMGMV is not likely to have adverse effects on the environment. Gordon and K.P. At yet another level, the effects could be expanded to include the indirect economic losses resulting from the reduction of ecological services in a TSA-dominated environment (Thomas 2011). USDA, APHIS,PPQ. Gratiana boliviana population density increased in the spring, and was typically highest during the summer. (1995) demonstrated that under laboratory conditions these two beetles also developed and reproduced on other Solanum species that do not occur in the insects’ native ranges. A., Mullahey, J. J., Langeland, K. A. and Kline, W. N. 2006. FUELS AND FIRE REGIMES: Abstr. Best management practices need to account for the potential that root stock and seed will survive winters north of the frost-free areas. 2.

Furthermore, the native SLN is attacked by a complex of natural enemies that also may attack the three invasive Solanum spp. With colder winters, TSA can function as a facultative annual when seedling emergence is early enough for plants to produce fruit before frost. Tropical soda apple was probably not present when reference fire regimes were functioning but has established since habitat alteration and fire exclusion began. In TeBeest, D. O. 2008). Internet: http://www.aphis.usda.gov/ppq/bats/fnwsbycat-e.html. This response is highly host-specific as shown by the fact that among plants that are susceptible to TMGMV, only TSA is killed totally and in a characteristic and predictable manner with the appearance of hypersensitive necrotic lesions on the leaves (Figure 1) followed by wilting of the plant and death (Figures 2 and 3). Chemical control: Tropical soda apple's increased fecundity with increased phosphorus levels (see Despite the difficulties of dealing with an invasive plant in such a taxonomic group, biological control of TSA is one of the most successful projects and the first attempt using insects as biocontrol agents of a Solanum weed in North America (Díaz et al. In a controlled experiment, tropical soda apple plants of various ages (1-55 days old) regrew from adventitious buds after cutting. West Florida Research and Education Center and the provide information on biological control of tropical soda apple. fruits and that birds may not serve as a vector for tropical soda apple's spread [23]. provide information on tropical soda apple control. To date, 70 field trials have been done at different locations in 19 counties throughout Florida. Gibbs, A., 1999. Integrated management: Germination rates increased up to 82% when seed was subject to dormancy-breaking acid treatments and exposed to the same alternating Herbaria collections indicate that tropical soda apple occasionally occurs in strand swamps, scrub, and mesic flatwoods [106].

Control of Tropical Soda Apple by Using a Plant Virus as a Bioherbicide, G. Herbicide Strategies for Tropical Soda Apple. At the time of this survey (2006), the preferred method of TSA control was chemical herbicide, with usage ranging from 20% to 48% for north and south Florida respectively. Canadian Entomol. undesirable vegetation, Monitor burned areas and areas of significant disturbance or traffic from management activity, Detect weeds early and eradicate before vegetative spread and/or seed dispersal, Eradicate small patches and contain or control large infestations within or adjacent to the burned area, Reestablish vegetation on bare ground as soon as possible, Avoid use of fertilizers in postfire rehabilitation and restoration, Use only certified weed-free seed mixes when revegetation is necessary. The immature fruit is green with white mottling like a watermelon and serves as a distinguishing characteristic. and Colvin, D.L. 61:255-260. NEWSS 52:22. Economic Botany 38: 210-217. Solanum viarum Dunal. 2008. However, no seed remained viable after 90 days [63]. least one county (Jasper County) in Texas by 2004 [90]. Table 6: Estimated Economic Impact by Region. Cuda, J. P., Parker, P. E., Goodson, R. A. and Gillmore, J. L. 1998. In 2007, G. boliviana Agric. Herbicides that possess post-emergence control of existing plants and pre-emergence control of germinating seeds are used on both large stands as well as sparse infestations. Tech. TMGMV provided nearly 100% TSA control; the green areas in the two plots with dead TSA are grasses and other weeds. The spines on tropical soda apple can degrade wildlife habitat by creating physical barriers for animal movement, especially in large infestations [26]. At each site, 10 plants were sampled by walking a straight line through the center of the infested area and selecting a plant every 5 steps. Germination may be low for tropical soda apple seeds on the soil surface (see Tropical soda apple seed dispersal throughout Florida and into other parts of the southeastern United States has been largely facilitated by cattle and operations associated with the transport of livestock and feed [26,59,65,85]. Florida Department of Agriculture and Consumer Services. One review suggested that tropical soda apple preferred open to semishaded However, a computer model (CLIMEX) that uses various climatic factors to predict whether insects can colonize and persist in new geographic areas (Sutherst & Maywald 1985) indicated that Leptinotarsa beetles collected from silverleaf nightshade in the Brownsville area of south Texas could establish and persist in peninsular Florida if tropical soda apple, wetland nightshade or turkey berry were suitable host plants. (2004) Genetic Variation in Native and Introduced Populations of Tropical Soda Apple (Solanum viarum), Weed Technology, 18, 1120-1124. In the laboratory, 20% of tropical soda apple seed collected in Florida was dormant [2].

Because we found that TSA and WNS were unsuitable host plants for D. phyllobius, we concluded that this foliar nematode had no value as a biological control agent for these two invasive Solanum species. Poison Apple (Solanum panduriforme) Poison Apple (Solanum panduriforme) family Solanaceae. The probability of some cultivars of peppers and tobacco being at risk from the use of TMGMV is negligible and manageable because the bioherbicide will not be labeled for use near these plants grown as crops. Through carefully planned and executed research at the University of Florida, it has been determined that TMGMV could be developed and used as a biological herbicide to control TSA (Charudattan et al. In spite of its native status, Florida horsenettle is listed as a troublesome weed by Hall & Vandiver (1991). tropical soda apple seed may germinate in full light or in shade. Interpreting ambiguous results of host-specificity tests in biological control of weeds: assessment of two Leptinotarsa species (Chrysomelidae) for the control of Solanum elaeagnifolium (Solanaceae) in South Africa. In Florida, tropical soda apple was listed in 1994 on the state's noxious Tropical Soda Apple (Solanum viarum) is now under a Biosecurity Control Order across all New South Wales Local Control Authorities (LCA’s). Restrictions on the interstate movement of livestock, seed, hay, soil, and manure may have additional economic impacts to the beef cattle industry [34]. Tropical soda apple occurred in the understory margins of saw-palmetto (Serenoa repens) [72], a species commonly found on the perimeter of hammocks [40]. TMGMV can be inactivated by ultraviolet light (Siegel and Wildman 1956; Siegel et al. Weed Science 19: 45-51. A total of 113 randomly selected sites with TSA were surveyed in 38 counties (Figure 5). 71:8316-8320. Distribution of tropical soda apple in The United States (Source: www.eddmaps.org 2011. 55:471-483. Edibility is doubtful, botantical references vague, identification difficult. Ferrell, J. Therefore, when you buy cattle, hold them in one area for up to six days to avoid the spread of TSA to other areas on your ranch. Hammocks can be hydric, mesic, or xeric and are most frequently defined by their topographic location (e.g., high, middle, or low slope) rather than their moisture content. Plants in this category pose a severe threat in Tennessee because of their invasive tendencies and their ability to spread easily into native plant communities and displace native vegetation [89]. Herbaria records show that it had spread to at Chapman and Hall, New York (a text for teaching biological control), 539 pp. Akanda, R. A., Mullahey, J. J., and Shilling, D. G. 1997. 2000). Trenholm [91] provides a detailed analysis of nutrient accumulation in tropical soda apple that may help to identify optimal herbicide application timing. Seedlings in a Florida pasture took 60 to 80 days to get about 8 inches (20 cm) tall and only had 4 to 8 leaves/plant. Kreiser, B. R., Bryson, C. T., and Usnick, S. J.
