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.

Our university has been part of the rich tradition of Rag CS (community service) since 1948. During 2011/2012, KovsieRag CS distributed R2 million to charities.

 

Rag CS will continue the tradition next year. The process began as early as March this year when Rag CS received and processed more than 100 applications and chose 50 women and 25 men as semi-finalists. The men and women had the opportunity to collect money until October. A total of R400 000 was collected. The 20 debutants (10 men and 10 women) who collected the most money were chosen as the 10 Brutal Fruit Rag CS finalists and the 10 Mr Rag CS finalists for 2012/2013.

 

These students were recently treated to a breakfast at Bain’s Game Lodge. Every finalist chooses a charity for which they will collect money.

 

Mr Rag CS 2013 and the Rag CS Queen will be chosen at the Crowning Ball on 15 February 2013.
