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.

Researchers who attended the workshop are, from the left, front: Ms Florence Tladi, Department of Psychology, Ms Makoena Moloi, Department of Plant Sciences, Ms Tobeka Mehlomakhulu, Department of Geography, Ms Nomampondomise Molefe, Department of Chemistry, Dr Micheal van Wyk, Department of Curriculum Studies, Prof. Mabokang ‘Monnapula-Mapesela, CHESD; back: Dr Sebolai, Prof. Muriel Meiring, Department of Hematology and Cell Biology, Mr Mathabatha Maleka, Department of Genetics, Mr Coleman, Dr Gregory Alexander, Department of Psychology of Education, Ms Dorine Masiangoako, Department of Chemistry, and Ms Moipone Mokoena, Department of Chemistry.
Dr Olihile Sebolai, Directorate Research Development, recently organised a series of workshops which is aimed at imparting new skills and knowledge to young and emerging academics.

The directorate endeavored to capacitate the new generation of researchers at the university with skills enable them to be established within the competitive mainstream of research. This is in line with the research strategy of the university that seeks to cultivate a strong culture of research.

Amongst others the workshops focused on innovative ways of adding value to student supervision and improving research project management skills. These workshops were facilitated by Dr Pieter du Toit from the University of Pretoria and Mr William Coleman from the Central University of Technology. Follow up sessions are planned for 2009 to assess the impact of these workshops.
