Prof Botma Visser takes on rust diseases threatening South Africa’s wheat

Safeguarding one of the world’s most vital staple foods was at the heart of the inaugural lecture delivered by Prof Botma Visser, Professor in the Department of Plant Sciences at the University of the Free State (UFS), on Wednesday 3 September 2025. Prof Visser shared insights from nearly two decades of research into wheat rust – a devastating crop disease that threatens both South Africa’s harvests and global food security.

“Wheat production in South Africa is threatened by three fungal pathogens that cause rust disease on the crop. Understanding the factors that contribute to virulence on locally grown cultivars is crucial to ensure continued wheat production,” said Prof Visser.

The fight against evolving wheat rusts

For the past 17 years, Prof Visser’s research has focused on the genetic structure of rust populations and the risks they pose to food security. His work has shown that these populations are dynamic and constantly changing due to genetic mutations within existing races, as well as the introduction of new races into South Africa.

“Computer modelling showed that rust can spread over vast distances by prevailing winds. During the 20th Century, at least four Southern African stem rust races managed to move across the Indian Ocean from Southern Africa to Australia. South Africa, in turn, received multiple new races from mid-Africa across Zambia and Zimbabwe, without any means of stopping these introductions,” he explained.

To respond to this challenge, his team recently implemented MARPLE (Mobile And Real-time Plant disEase) diagnostics using fourth-generation nanopore sequencing technology. This approach allows the rapid characterisation of fungal isolates, specifically targeting genes linked to fungicide resistance and virulence.

“This work,” Prof Visser noted, “is part of an effort to safeguard global wheat production.”

His research is a collaborative effort with Prof Willem Boshoff (Department of Plant Sciences, UFS) and Dr Tarekegn Terefe (Agricultural Research Council – Small Grain, Bethlehem). Together, their work has positioned the UFS as an internationally recognised centre of excellence in wheat rust research.

About Prof Botma Visser

Prof Botma Visser obtained his BSc in Botany and Microbiology (1988), BSc Honours in Microbiology (1989), and MSc in Botany (1993) at the University of the Free State, where he also completed his PhD in Botany in 2004.

His career spans more than 18 years of research into wheat rust pathogens, combining annual surveys, race pathotyping, molecular genetics, and cutting-edge sequencing technologies. His expertise has not only advanced understanding of rust population dynamics in South Africa but also contributed to global collaborative studies on crop disease.

Centenary celebrations of Faculty of Law reach a highlight

The Faculty of Law at the University of the Free State (UFS) reached the highlight of its celebrations of a century of excellence in legal education, training and research under the theme “Iurisprudentia 100” at a gala dinner held on the Main Campus in Bloemfontein last week.

At this spectacular occasion Prof. Johan Henning, Dean of the Faculty handed a Cum Laude award to Judge Faan Hancke, Chairperson of the UFS Council and Extraordinary Professor in the Department of Law of Procedure and Law of Evidence. Judge Hancke is the fourth recipient of this award. Judge Hancke received the award for his excellent contributions towards the building of the Faculty of Law and the UFS.

According to Prof. Henning the faculty has a distinguished history of excellence in theoretical as well as practical education and training, which can be traced as far back as to the establishment of the Grey University College in 1904. During this modest beginning the seed was planted for the establishment of the Faculty of Law, which gained momentum when Bloemfontein became the judicial capital of South Africa in 1910.

Other highlights in legal education at the UFS include, amongst others, 1909 when Adv. Percy Fisher, a BA LLB graduate from the University of Cambridge became the first law lecturer to receive a permanent appointment. In 1918 the first LLB degrees were awarded to SP le Roux, later Minister of Agriculture, CR Swart, later Minister of Justice, Governor-General, State President and the first Chancellor of the UFS, and Walther Leinberger, an attorney in town.

In 1945 Law became an independent faculty and in 1948 the first full-time professor, Dr JP Verloren van Themaat was appointed. After Prof. Van Themaat, six deans followed before the appointment of Prof. Henning.

Over the last ten years the faculty has managed to build many international contacts with international leaders in the legal arena, including the Universities of London, Cambridge, Sussex, Tilburg, Kentucky, Heidelberg, Freiburg, Utrecht and Deacon.

The faculty prides itself on the fact that he has prepared many students as well as lecturers who later became presidents, ministers, administrators, judges of appeal, judges and rectors. The faculty has 95 staff members and 2 400 students, of which 1 800 are postgraduate students.

National as well as international leaders in the legal field congratulated the faculty on its 100-year celebrations. Messages of congratulations were also received from, amongst others, universities, legal practices and the government.
