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.

Minister praises MUCPP initiative

2004-10-04

The Minister of Labour, Mr MMS Mdladlana, singled out the Mangaung University of the Free State Community Partnership Programme (MUCPP) for high praise during a conference at the MUCPP complex on 30 September 2004 .

“I am very pleased with what the partnership of different stakeholders can do and I thank all stakeholders for contributing to this initiative. This is the kind of energy that our country needs,” the minister told delegates to the conference.

He said the MUCPP was a very unusual and important partnership that is related directly to the mandate of government and supports two strategic objectives of government, namely halving poverty and halving unemployment.

The MUCPP was launched in 1991 as a partnership between the University of the Free State , the local community of Mangaung, local and provincial government and the private sector, in an effort to develop skills and contribute to fighting poverty.

Some of the existing projects of the MUCPP include:

Health centre (including a 24-hour maternity ward)
Dairy producing yoghurt and amasi
Sewing and knitting project
Indigenous food production (Tsa se tso)
Bakery
Bed and Breakfast accommodation
Etsa phapang (a hydroponic facility growing various vegetables)
Welding project
Low cost housing project
Sport and recreation facilities and programmes

According to the Minister, hundreds of young people, adult learners and people with disabilities have benefited from training and skills development and have become involved in carpentry, welding, painting, cleaning services, gardening and HIV / AIDS awareness programmes.

Minister Mdladlana said he was pleased that through partnerships with several Sector Education and Training Authorities (SETAs) which fall under the Department of Labour, the MUCPP could access hundreds of thousands of rands for such training and development.

“I can just salute those that have made it possible, and to encourage you to keep up the good work,” the minister said.

The MUCPP also provides a means for students of the UFS to render community service. The UFS was one of the first universities in South Africa to adopt a comprehensive community service policy in 2002. In terms of the policy, community service is integrated into curricula through service learning modules.

It is therefore of great importance that the UFS should support community sites such as the MUCPP where a holistic and integrated approach to mutual and reciprocal development of all partners is followed.
