Box 524, Auckland Park 2006, Johannesburg, South Africa Received 4 November 2011; received in revised form 18 November 2011; accepted 21 November 2011 Abstract Asphodelus fistulosus or onionweed is recorded in South Africa for the first time and is the first record of an invasive member of the Asphodelaceae in the country. Only two populations of this plant have been observed, both along disturbed roadsides on the West Coast of South Africa. The extent and invasive potential of this infestation in the country is still limited but the species is known to be an aggressive invader in other parts of the world. © 2011 SAAB.

Status of Biological Control of Tropical Soda Apple, Solanum Viarum, in Florida1
Botany Circular No. 36 Fl. Dept. of Agriculture & Cons. Svcs. September/October 2002 Division of Plant Industry Status of Biological Control of Tropical Soda Apple, Solanum viarum, in Florida1 Julio C. Medal2, Nancy C. Coile3, Daniel Gandolfo4, James P. Cuda5 INTRODUCTION: Tropical soda apple (TSA), Solanum viarum Dunal (Solanaceae), a perennial prickly weed native to South America (Fig. 1), has been spreading rapidly in the USA since it was discovered in Glades County, Florida in 1988. In Florida, approximately 150,000 acres (60,704 ha) of pasture land were infested in 1992 (Mullahey et al. 1993). Currently, the infested area is estimated at over 1 million acres (404,694 ha). TSA also invades hammocks, ditch banks, citrus groves, vegetable fields, sugarcane fields and roadsides. TSA also has been reported in Alabama, Georgia, Louisiana, Texas, Mississippi, North Carolina, South Carolina, Tennessee, Pennsylvania and Puerto Rico (Bryson and Byrd Jr. 1996; Dowler 1996; Mullahey et al. 1997; Phil Lewis personal commu- nication). TSA was placed on the Florida Noxious Weed List in 1994, and the Federal Noxious Weed List in 1995, and is listed as one of the most invasive species in Florida by the Florida Exotic Pest Plant Council (1999) (Fig. 2). Fig. 1. Tropical soda apple. (Photography credit: J. Mullahey, Fig. 2. Tropical soda apple in South Florida. (Photography UF-IFAS.) credit: J. Lotz, DPI.) The invasiveness of TSA is attributed to several characteristics. A single plant produces about 150 fruits per year, and each mature fruit contains about 400 seeds. Up to 60,000 seeds are produced per plant with a germination rate of at least 75% (Mullahey et al., 1993, Pereira et al., 1997). -
California Department of Food and Agriculture
DEPARTMENT OF FOOD AND AGRICULTURE PROPOSED CHANGES IN THE REGULATIONS Title 3, California Code of Regulations Section 4500 Noxious Weed Species INITIAL STATEMENT OF REASONS/ POLICY STATEMENT OVERVIEW Description of Public Problem, Administration Requirement, or Other Condition or Circumstance the Regulation is Intended to Address This regulation is intended to address the obligation of the Department of Food and Agriculture (Department) to protect the agricultural industry from the movement and spread of injurious noxious weeds into and within California. Specific Purpose and Factual Basis The specific purpose of section 4500 is to provide authority to the state to regulate the movement of the listed noxious weeds species into or within California. The factual basis for the determination by the Department that the amendment of this regulation is necessary is as follows: Invasive weeds have significant effects on the agricultural industry and environment. They can intensify drought impacts, increase fire hazard, decrease rangeland productivity, reduce water resources, raise nursery business costs, and diminish wildland diversity. Alien weeds spread to and invade approximately 700,000 hectares per year of U.S. wildlife habitat. One such pest weed, introduced in the early 19th century as an ornamental plant, is the European purple loosestrife. Spreading at a rate of 115,000 hectares per year, the weed population changes the basic structure of most of the invaded wetlands. Competitive stands of purple loosestrife have reduced the biomass of 44 native plant species and endangered wildlife such as the bog turtle that depends on these native plants. Loosestrife now occurs in 48 states and costs $45 million per year in control expenses and forage losses. -
Analysis of Genetic Diversity of Guizotia Abyssinica from Ethiopia Using Inter Simple Sequence Repeat Markers

Analysis of genetic diversity of Guizotia abyssinica from Ethiopia using inter simple sequence repeat markers. * Hereditas 144:18Á24. Lund, Sweden. eISSN 1601-5223. Received August 10, 2006. Accepted November 28, 2006 Within and among population genetic diversity of 37 Guizotia abyssinica populations from Ethiopia were analyzed using inter simple sequence repeats (ISSRs). Five primers amplified a total of 118 genomic DNA fragments across a total of 370 individuals of which 106 were polymorphic (89.83%). The average number of polymorphic bands per primer was 21.2. More bands were generated by primer UBC 888 (BDB(CA)7. The total genetic diversity (Ht) and the coefficient of genetic differentiation (Gst) were 0.4115 and 0.0918 respectively, while the within population genetic diversity (Hs) and the among population genetic diversity(Dst) were 0.3738 and 0.03776 respectively suggesting more variability within the populations than among them. The standard genetic distances between the G. abyssinica populations of the eight regions ranged from 0.0281 (between Wollo and Gojam) to 0.1148 (between Jimma and Hararghe). Generally, the standard genetic distances are smaller between populations of neighboring regions and highest between those of Jimma and the other regions, ranging from 0.0696 (between Jimma and Shewa) to 0.1148 (between Jimma and Hararghe). The ISSR based UPGMA clustering using the standardized genetic distances matrix also placed populations from neighboring regions closer than those from farther apart areas, while the UPGMA clustering by regions based on the standard genetic distances produced three clusters following the proximity and the contiguity of the regions. -
A Potential Biocontrol Agent of Tropical Soda Apple, Solanum Viarum (Solanaceae) in the USA
Risk assessment of Gratiana boliviana (Chrysomelidae), a potential biocontrol agent of tropical soda apple, Solanum viarum (Solanaceae) in the USA J. Medal,1,2 D. Gandolfo,3 F. McKay3 and J. Cuda1 Summary Solanum viarum (Solanaceae), known by the common name tropical soda apple, is a perennial prickly weed native to north-eastern Argentina, south-eastern Brazil, Paraguay, and Uruguay, that has been spreading at an alarming rate in the USA during the 1990s. First detected in the USA in 1988, it has already invaded more than 1 million acres (ca. 400,000 ha) of improved pastures and woody areas in nine states. Initial field explorations in South America for potential biocontrol agents were initiated in June 1994 by University of Florida researchers in collaboration with Brazilian and Argentinean scientists. The leaf beetle Gratiana boliviana (Chrysomelidae) was evaluated as a potential biocontrol agent of tropical soda apple. The only known hosts of this insect are S. viarum and Solanum palinacanthum. Open field experiments and field surveys were conducted to assess the risk of G. boliviana using Solanum melongena (eggplant) as an alternative host. In an open field (choice-test) planted with tropical soda apple and eggplant there was no feeding or oviposition by G. boliviana adults on eggplant. Surveys conducted (1997–2002) of 34 unsprayed fields of eggplant confirmed that this crop is not a host of G. boliviana. Based on these results, the Florida quarantine host-specificity tests, the open field tests in Argentina, and the lack of unfavourable host records in the scientific literature, we concluded that G. -

Even with all good factors involved, germinating power loss occurs. However, this loss may be reduced by performing procedures to maintain quality, as storage local and packaging. Thus, the objective of the work was to identify the best environment and packaging for storing niger seeds by analyzing germination and seedling biometry. Samples were separated according to treatments being three types of packaging: paper bag (permeable), plastic bag (semi- permeable) and glass container (impermeable). -

Tropical Soda Apple Identification and Control ► This Invasive Plant Can Greatly Reduce Forage Productivity
FORESTRY & WILDLIFE Tropical Soda Apple Identification and Control ► This invasive plant can greatly reduce forage productivity. Learn important measures you can take to prevent its spread. Tropical soda apple (Solanum viarum), also referred to as TSA, is a non-native, invasive weed that forms very dense infestations, especially in pastures. Forage productivity can be greatly reduced as a result. It is also a host of several diseases and pests of commercial crops. Listed by the USDA as a federal noxious weed, TSA was nearly eliminated across the state a decade ago through a federally funded eradication program. With termination of program funding, however, reports of TSA infestation are on the rise. For producers, timely identification and control of this invader will help to prevent its spread and protect your forage. Figure 2. Tropical soda apple flowers have five separate white petals that curl back with age. The leaves and stems have large prickles. How do I identify tropical soda apple? ■ Leaves: 4 to 6 inches long and 2 to 6 inches wide, There are several species in the nightshade genus shallowly lobed with dense, sticky pubescence (Solanum) that might be confused with TSA. The (velvety hair) on both sides, large prickles (½ to most common look-alike is Carolina horsenettle (S. 1 inch) occur along the midveins on the upper carolinense). TSA looks a bit like Carolina horsenettle and lower surfaces of leaves and along the stem. on steroids—the plants, leaves, thorns, and fruit are all Carolina horsenettle leaves tend to be more narrow bigger. and the prickles are much smaller and only on veins Following are key features to help you identify tropical on the bottom surface of the leaves. -

The objective of this study was to investigate the mineral and anti-nutritional contents of different varieties of niger seed, linseed and sesame. Five niger seed, eight linseed and ten sesame varieties were used. Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) was used for mineral analysis and the standard method was adopted to estimate tannin and phytate. Twelve mineral elements; Ca, K, Mg, Na, P, B, Cu, Fe, Mn, S, Se and Zn were analyzed for each oilseed variety. In niger seed, phosphorous was the most abundant mineral element ranging from 661 to 867 mg/100 g and selenium was the least, ranging from 0.1 to 0.33 mg/100 g.
