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.

Department arranges special excursion for disabled students
2008-11-26

 

The unique circumstances of students with disabilities often make it difficult for them to attend educational excursions of the Department of Communication and Information Studies. A special excursion was thus arranged for them to the National Museum in Bloemfontein. Work was recently done to make the museum more accessible for persons with disabilities. A lift was installed and exhibitions are equipped with Braille. Many exhibitions are equipped with sound and visitors can also make use of audio players.

Mr Tebogo Mohlakane, educational officer from the National Museum, and a team of well-trained museum guides welcomed the 13 students that were accompanied by Ms Elbie Lombard and other members of the department with open arms. Each student received special attention to make it an unforgettable experience.

Estine Smith, a first-year student with visual impairments, summarised her experience of a stuffed predatory bird which she held in her arms, as awesome. Touching replicas of elephants, rhinos and giraffes was the highlight of Shaun Jooste, a third-year student with visual impairments’ experience. Until recently it was difficult for Tshidiso Molehe to visit the museum with his wheelchair. He is now satisfied with the accessibility of the museum and is looking forward to his next visit to the museum.
