The University of the Free State will hope to start developing their next Wayde van Niekerk when the first Varsity athletics meeting takes place on Friday at the Tuks Athletics Stadium in Pretoria.
The second meeting is on 23 March, also in Pretoria.
Thirteen members (five men and eight women) of the Kovsie team of 25 are still under the age of 21.
The hope for medals among the men would be on Sefako Mokhosoa (triple jump), Hendrik Maartens, and Tsebo Matsoso (both 200 m). Mokhosoa, who represented South Africa last year at the Southern Region Championships, is in red-hot form and achieved a personal best of 16.13 m at the Motheo/Xhariep meeting two weeks ago. This is currently the third best distance in the country for 2018.
Maartens would like to go one step further. In last year’s final Varsity meeting, he finished second in 20.62. Great things are expected of Matsoso, a first-year student who competed at the African Junior Championship in 2017. Last year, he was one of the top athletes at school level by winning the SA title in a time of 21.14.
Ts’epang Sello (800 m) and Elmé Smith (100 m and 200 m) will lead the charge for the women. Sello already came close to her personal best (2:09.8) this year, while Smith has also been running fast times. Her best this year was 11.88 (100 m) and 24.53 (200 m).
Tyler Beling (1 500 m) is another first-year student who is showing great potential. She obtained a fourth position at last weekend’s CAA Southern Region Cross-country Championships. Maryke Brits (100 m hurdles and long jump) is a possible medallist, despite running her first event for the year on Wednesday night.
The meeting starts at 17:15 and will be broadcast on SuperSport 5.
Names are not enough: a molecular-based information system is the answer

South Africa is the second-largest exporter of citrus in the world, producing 60% of all citrus grown in the Southern Hemisphere. It exports more than 70 % of its citrus crop to the European Union and USA. Not being able to manage fungal pathogens effectively can have a serious impact on the global trade in not only citrus but also other food and fibre crops, such as bananas, coffee, and cacao.
The Department of Plant Sciences at the University of the Free State (UFS) hosted a public lecture by Prof Pedro W. Crous entitled “Fungal Pathogens Impact Trade in Food and Fibre: The Need to Move Beyond Linnaeus” on the Bloemfontein Campus.
Prof Crous is Director of the world’s largest fungal Biological Resource Centre, the Centraalbureau voor Schimmelcultures (CBS), in the Netherlands. He is also one of the top mycologists in the world.
Since the topic of his lecture was very pertinent to food security and food safety worldwide, it was co-hosted by the Collaborative Consortium for Broadening the Food Base, a multi-institutional research programme managed by Prof Wijnand Swart in the Department of Plant Sciences.
Reconsider the manner in which pathogens are identified
Prof Crous stressed that, because international trade in products from agricultural crops will expand, the introduction of fungal pathogens to new regions will increase. “There is therefore an urgent need to reconsider the manner in which these pathogens are identified and treated,” he said.
According to Prof Crous, the older Linnaean system for naming living organisms cannot deal with future trade-related challenges involving pests and pathogens. A system, able to identify fungi based on their DNA and genetic coding, will equip scientists with the knowledge to know what they are dealing with, and whether it is a friendly or harmful fungus.

Embrace the molecular-based information system
Prof Crous said that, as a consequence, scientists must embrace new technologies, such as the molecular-based information system for fungi, in order to provide the required knowledge.
He presented this very exciting system which will govern the manner in which fungal pathogens linked to world trade are described. This system ensures that people from different countries will know with which pathogen they are dealing. Further, it will assist with the management of pathogens, ensuring that harmful pathogens do not spread from one country to another.
More about Prof Pedro Crous
Prof Crous is an Affiliated Professor at six international universities, including the UFS, where he is associated with the Department of Plant Sciences. He has initiated several major activities to facilitate global research on fungal biodiversity, and has published more than 600 scientific papers, many in high impact journals, and authored or edited more than 20 books.
