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.

New Head for the School of Mathematics, Natural Sciences and Technology Education
2013-02-27

27 February 2013

Prof Sechaba Mahlomoholo from the Faculty of Education at the University of the Free State was recently appointed as Head of the School of Mathematics, Natural Sciences and Technology Education (SMNSTE).

As head of the school, his duties will include improving the learning, teaching and curricula of maths, natural sciences and technology at school and at post-school levels.

“The solution seems to be to move the SMNSTE into a very intensive praxis mode where, through our high-level research-based classroom practices, we can formulate strategies together with teachers, parents, learners and the Department of Education, to enhance learner performance in the abovementioned subjects. Our plan, therefore, is to facilitate the establishment of closely knit learning communities of practice around these three subjects, with the SMNSTE being the epicentre of thought and action, while schools, mainly in the Free State, will serve as other nodal points for this intensive praxis. We believe that the SMNSTE will come to its fullness once student and learner performance is respectable, and as such positions our country favourably among the community of nations. SMNSTE is a national facility which has to respond to national challenges effectively.”
