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.

Three international hockey teams have used the practice facilities of the university since the beginning of the year to prepare for the Olympic Games in August this year. The German and South African hockey teams have practiced here on four previous occasions.

Due to the cold weather in Europe, Austria also held its hockey training camp at the university this year. In addition, four of Austria’s triathlon athletes used the cross country track and swimming pool on the Bloemfontein Campus to prepare for the Olympic Games.

Germany’s national hockey team practised at the university from 3 to 12 March 2012. South Africa made use of the facilities from 5 to 10 March and Austria’s national team has been practicing in Bloemfontein since 24 February. From 3 to 10 March, a club team from Austria also made use of the university’s facilities, including the astros, the swimming pool, the athletics track and the Biokinetics Centre. SV Arminem also played two matches against the men’s hockey team from Kovsies. The first match end 2-2. With the second match Kovsies won 4-1.

Other international hockey teams who have made use of the astros over the past six years include Russia, Argentina, Belgium, China, Azerbaidjan and the Netherlands.

Staff ensured that everything ran like clockwork during the different training camps. Ms Annemarie Ludick and Mr Frans van der Watt, under the guidance of Mr Mickey Gordon, Head: Institutional Promotion, Fundraising, Marketing and Sport, were responsible for the logistical arrangements and finances. Mr Johan Gerber saw to the maintenance of the astros. The university boasts some of the best equipped astros in the world. “Germany, for example, did not bring along any exercise balls, cones, or beds (for use by physiotherapists) because the astros are fully equipped,” said Ms Ludick.

The fact that international teams such as Germany (ranked second in the world), South Africa and Austria made use of the university’s facilities is significant. “The university’s first team got for example the opportunity to play practice games against these players. The training camps also contributed to the economy of Bloemfontein,” said Ms Ludick.
