Experiencing the UFS in person for the first time are from the left: Sandor Potjer (VU Amsterdam), Bulelwa Moikwatlhai (UFS OIA), Ricarda Kochems (Bremen University, Germany), Froukje Pronk (VU Amsterdam) and Matome Mokoena (UFS OIA)
As the UFS COVID-19 Regulations and Required Vaccination Policy has been lifted with immediate effect – allowing 100% capacity of both students and staff members and a fully operational campus – the
Office for International Affairs welcomes its first physical exchange cohort after two years. The cohort of students hail from the various international partners of the UFS, namely the
University of Bremen in Germany, the Vrije Universiteit Amsterdam, and Sciences PO Bordeaux in France. The students will be hosted in the UFS faculties of the Humanities, Economic and Management Sciences, and Natural and Agricultural Sciences, respectively.
These students have been paired with
Umoja Buddy Programme ambassadors to help ensure their smooth transition and integration into student life at the UFS. Furthermore, the students received an invitation from the President of the
International Student Association (ISA), Courtney Madziwa, to join their association, thus exposing them to students from other countries to learn about the various cultures.
On 18 July, the Office for International Affairs (OIA) arranged a hybrid orientation programme for the exchange students, including those students who have not yet arrived on the Bloemfontein Campus. The students took part in an icebreaker activity, where they had the opportunity to learn from and teach other participants about their home countries. Dr Cornelius Hagenmeier, Director of the OIA, welcomed the exchange students to the Bloemfontein Campus, and expressed excitement to have physical exchanges again. Furthermore, the guest presenters ranged from student leadership, staff members, and service providers.
The presentations were practical, demonstrating, among others, how to create a password on the institutional website – presented by Mr Molemo Mohapi from UFS ICT. The presentation on how to fully utilise Blackboard was facilitated by Ms Vuthihi Mudau from the UFS CTL division. We take the safety of all our students seriously, so Ms Elise Oberholzer from the UFS Protection Services has given the students some tips on how to safeguard themselves.
Researcher works on finding practical solutions to plant diseases for farmers

Plant disease epidemics have wreaked havoc for many centuries. Notable examples are the devastating Great Famine in Ireland and the Witches of Salem.
Plant diseases form, due to a reaction to suitable environments, when a susceptible host and viable disease causal organism are present. If the interactions between these three factors are monitored over space and time the outcome has the ability to form a “simplification of reality”. This is more formally known as a plant disease model. Lisa Ann Rothman, a researcher in the Department of Plant Sciences at the University of the Free State (UFS) participated in the Three Minute Thesis competition in which she presented on Using mathematical models to predict plant disease.
Forecast models provide promise fighting plant diseases
The aim of Lisa’s study is to identify weather and other driving variables that interact with critical host growth stages and pathogens to favour disease incidence and severity, for future development of risk forecasting models. Lisa used the disease, sorghum grain mold, caused by colonisation of Fusarium graminearum, and concomitant mycotoxin production to illustrate the modelling process.
She said: “Internationally, forecasting models for many plant diseases exist and are applied commercially for important agricultural crops. The application of these models in a South African context has been limited, but provides promise for effective disease intervention technologies.
Contributing to the betterment of society
“My BSc Agric (Plant Pathology) undergraduate degree was completed in combination with Agrometeorology, agricultural weather science. I knew that I wanted to combine my love for weather science with my primary interest, Plant Pathology.
“My research is built on the statement of Lord Kelvin: ‘To measure is to know and if you cannot measure it, you cannot improve it’. Measuring the changes in plant disease epidemics allows for these models to be developed and ultimately provide practical solutions for our farmers. Plant disease prediction models have the potential ability to reduce the risk for famers, allowing the timing of fungicide applications to be optimised, thus protecting their yields and ultimately their livelihoods. I am continuing my studies in agriculture in the hope of contributing to the betterment of society.”
