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.

Through a series of joyous events, the University of the Free State’s (UFS) Qwaqwa, South, and Bloemfontein Campuses officially welcomed Prof Francis Petersen as the 14th Rector of the UFS during the past week.

Celebrations end on a high note
The Bloemfontein Campus would not be upstaged and they came out in full support. Performances by staff and student talent impressed the crowd. Invited school performances brought flair and a youthful energy to the celebrations.

Prof Petersen thanked all in attendance, including his family. “It has been a great time of prosperity and well wishes from all three campuses. I have experienced a sense of belonging. I want this experience for all staff, students, and for all those who visit our campus,” said Prof Petersen.

“There is an African idiom that says: ‘If you want to go fast, travel alone; but if you want to travel far, travel together’. If we want to go far as an institution, we will all need to travel together and that means working together,” Prof Petersen added.

Prof Petersen concluded by stating that the UFS is a good institution, but together, it will be a great institution, not just in Bloemfontein or the Free State, but in South Africa, in Africa, and finally globally.
