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.

UFS and Griqua National Conference work together
2009-03-04

 

Delegates from the Griqua National Conference (GNC) and role players from the University of the Free State (UFS) recently met on the South Campus of the UFS to put the objectives of a Memorandum of Understanding into practice. Some of the objectives are research, programmes and projects focusing on economic, educational, political, cultural/heritage and socio-social matters. “Research in different fields is important for the survival of the Griqua in South Africa and the UFS gives credibility to the Griqua’s research projects,” says Mr Cecil le Fleur, Chairperson of the GNC’s Council of Chiefs. According to Mr le Fleur, the GNC wants to work with the UFS because the institution reaches out to the communities of the Southern Free State. There is also mutualistic cooperation in this area that is of benefit to both partners. “Together with the UFS we will also be investigating the feasibility of the production of a documentary film on the role of the Griqua in the central interior, its political models and the role the Griqua played in the establishment of white settlers in this area. We also want to investigate and implement other relevant points of tangency,” says Mr le Fleur. Here are, from the left: Mr le Fleur, Ms Elizabeth le Fleur, Chairperson of the Cultural Group, which is one of the focus areas of the cooperation agreement, and Rev Kiepie Jaftha, Chief Director: Community Service at the UFS.
