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.

The University of the Free State (UFS) honoured its top achievers at a glamorous gala dinner in the Centenary Complex on the Bloemfontein Campus on Thursday 11 October 2012. Jamba Ulengo and Izelle Lategan were named the Sportsman and Sportswoman of the year respectively.

The Junior Sportsman and Sportswoman for 2012 are Raymond Rhule and Tanya Brits.

This year the university’s sport stars were honoured in five categories. This includes:

- Sportsman and Sportswoman of the year (everyone that represented South Africa at a senior level, was eligible for the title). The winners each received a trophy and each sportsman and sportswomen in this category were honoured with a medal.
- Junior sportsman and sportswoman of the year. The winners each received a trophy.
- Sport stars that represented South Africa at senior and junior level. The achievers received certificates.
- Sport stars that represented the UFS in the national student teams. The sport stars also received certificates.
- Certificates were also awarded to the KovsieSport club sport stars.

The following students represented South Africa at senior level:

- Nardus Greyling. He represented the SA Athletics Team in the Confederation of African Athletics Senior Championship.
- Boy Soke. He represented the SA Athletics Team in the Confederation of African Cross-country Championship
- Izelle Lategan. She represented the Investec SA Women’s Hockey Team in the Champs Challenge in Dublin, Ireland, in Holland and Belgium and she played for the SA U/21 team against Spain and Belgium. She was also captain of the SA U/21-team during the senior interprovincial championships.
- JVA Steytler. He represented the SA Athletics Team in the Confederation of African Athletics Senior Championship.
- Johan Cronjé. He represented the SA Athletics Team as a 1 500 m finalist in the Confederation of African Athletics Senior Championship. He also participated in the Dessau International meeting in Germany and the Grand Prix meeting in Prague.
