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.

State of our campuses: UFS Qwaqwa Campus temporarily closed until 18 April 2017
2017-04-03

The senior leadership of the University of the Free State (UFS) has decided to close the Qwaqwa Campus on Tuesday 28 March 2017 due to student protests regarding provisional registrations. Academic activities will resume on 18 April 2017. 
 
The protests were preceded by a meeting of the campus management with the Student Representative Council (SRC) on 22 March 2017 to discuss issues pertaining to students who are provisionally registered – especially those students who are provisionally registered and awaiting the outcome of their appeals to the National Student Financial Aid Scheme (NSFAS).
 
On 27 March 2017, the SRC handed a memorandum to the campus management, requesting assistance in cases that are on appeal with NSFAS. The students also demanded extension of the provisional registration deadline of 31 March 2017, and that a fundraising plan should be implemented for financially needy students. The campus management made a commitment to respond within the deadline stipulated in the memorandum.
 
After the meeting, violence erupted when a group of students started intimidating students, barricading the entrance to the campus, and damaging university property. An interdict was served by the Sheriff later the same afternoon and additional security was deployed. On 28 March 2017, the violent protests and barricades spilled onto the provincial road to Phuthaditjhaba and several cars were damaged. This led to the arrest of a number of students by members of the South African Police Service for the contravention of the High Court order and for public violence. The students have since been released.
 
Due to the imminent threat to the safety of staff and students on the campus, the senior leadership decided on 28 March 2017 to evacuate the residences and to close the campus temporarily until 18 April 2017.
             
“It is unfortunate that the students resorted to violence without waiting for the campus management’s response to the memorandum of 27 March 2017. What makes the situation difficult is the fact that students on provisional registration who are waiting for the outcome of their NSFAS appeals, are dealing directly with NSFAS. This makes it difficult for the university to intervene,” says Mr Teboho Manchu, acting Principal of the Qwaqwa Campus.
 
The senior leadership of the UFS is aware of the video clip on social media this week, where a student is allegedly beaten by security guards on the Qwaqwa Campus. The senior leadership condemns this deplorable incident. An investigation is underway to determine the nature and cause of the incident. Appropriate steps will be taken once the outcome of the investigation is available.
