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.

On 9 October,2004, the Mandela Hall at the UFS-Qwaqwa Campus was filled to capacity as the community gathered to celebrate the graduation of 177 students. Among the degrees awarded were : one doctorate , eight masters,31 honours and 46 bachelors. In addition, there were also 91 diplomas awarded.

The conferring of the first doctorate in the Natural and Agricultural Sciences to Dr Motseki Hlatshwayo made a history for our campus, because it was done for first time. This is a cause for celebration and attests to the resilience of staff and students, and to the commitment and support of our immediate community for the continued offer of relevant post graduate training here on the Qwaqwa campus of the University of the Free State.

Amongst the dignitaries was the Director of Thabo Mofutsanyane District, Mrs BS Tshabalala. In his welcome speech, the Campus Head, Prof Peter Mbati said “ a special day like today is normally only possible due to the dedication and commitment of many different individuals. It is therefore only fitting that we salute you the parents and guardians for all your sacrifices to ensure that your children get the best education”

The 1st Deputy President of the SRC, Mr Tello Motloung also adressedthe granduands. “The year 2004 calls for celebration, as we are celebrating 10 years of democracy. Therefore, it is not a coincidence that we are also meeting
