Marcele Vermeulen, a graduate from the Department of Plant Sciences, explores possible threats to crop production; contributing to food security in South Africa.

Global food security is currently threatened both by climate change and the low diversity of crops relied on by humankind to feed a growing world population. Marcele Vermeulen, a graduate in the Department of Plant Sciences who will receive her PhD at the December graduation ceremonies at the University of the Free State (UFS), is part of a team that is working hard to add to the diversity of staple foods in South Africa.

In the drive to focus on alternative crops, Marcele is researching the crop, Amaranthus cruentus, (grain amaranth). It is more tolerant to environmental stress for large-scale production, thereby also diversifying staple crops.

Relatively new development

“Amaranthus cruentus is an excellent candidate due to its high nutritional value and tolerance to drought and high temperatures. It can be mixed with conventional maize meal, to increase the protein intake of its consumers,” said Marcele.

The production of A. cruentus as a grain crop in South Africa is a relatively new development.

In her research, exploring the possible threats to crop production and paying particular attention to dominant plant pathogens in the Amaranthus cruentus, Marcele found a correlation between fungal pathogens and insect pests. 

Insect pests can influence plant diseases

Although reports on fungal pathogens and pests specific to A. cruentus are limited to and information for South Africa is limited to this study, there is a possibility that by controlling insect pests such as weevils, one might also be able to control fungal pathogens of Amaranthus cruentus.

Marcele believes that control of weevil pests should thus be the focus of future pest and pathogen management strategies and breeding programmes in A. cruentus.  

“Knowledge gained in my thesis will hopefully aid in the development of future cultivation practices, integrated pest/pathogen management programmes, as well as for the registration of crop protection products for A. cruentus,” Marcele added.

FS Premiers Documentary Film On Basotho King Moshoeshoe
2004-10-06

The University of the Free State (UFS) will premiere a documentary film on the legacy of King Moshoeshoe, Basotho leader of the nineteenth century for his role in nation-building and reconciliation on Wednesday 13 October 2004.

The hour-long documentary film, produced by the well-known journalist Mr Max du Preez, was commissioned by the UFS as part of its centenary celebrations.

“To us this film is a practical demonstration of the UFS’s commitment to the continued transformation of the campus, and its commitment to reconciliation and nation-building. It is seen as a contribution to one of the UFS’s key strategic priorities for this year, namely diversity, equity and redress,” says Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

“Through these priorities, the UFS commits itself to developing a shared appreciation of the history of this country and to contribute to the establishment of the Free State Province as a model of reconciliation and nation building,” says Prof Fourie.

“King Moshoeshoe was a great African statesman and leader. He was born in this region of the country, but his influence and legacy extends way beyond the borders of the Free State, Lesotho and even way beyond the borders of South Africa,” says Prof Fourie.

Earlier this year the UFS launched a project to honor King Moshoeshoe. The project included among others the production of this documentary film, the possible presentation of an annual Moshoeshoe memorial lecture that will focus on African leadership, nation-building and reconciliation and PhD-level research into the life and legacy of King Moshoeshoe and a literary anthology including prose and poetry.

According to Prof Fourie the project will enable the UFS to give real meaning to words such as reconciliation, respect for the diversity of our languages and cultures, and the unity South Africans seek to build as a democratic nation through such diversity.

The documentary film on King Moshoeshoe will be screened on SABC 2 later this year.
