Dr William Mhundwa, Senior Registrar in the Department of Internal Medicine at the University of the Free State (UFS), has become the first candidate from the institution to be awarded the prestigious Suzman Medal as the top student in the 2022 examinations of the Fellowship of the College of Physicians (FCP).  

Candidates from all medical schools in the country as well as other African countries wrote this examination in January and July 2022. Dr Mhundwa came out on top and was awarded the medal by the Senate of the Colleges of Medicine of South Africa (CMSA), which oversees the examinations.  

“I congratulate Dr Mhundwa on his outstanding performance,” commented Prof Nicholas Pearce, Head of the School: Clinical Medicine at the UFS. According to him, this is a prestigious award, and given that it is the first time that a candidate from this university has been awarded this medal, it is extra special for us as a department, faculty, and institution. 

Dr Mhundwa was born in Harare, Zimbabwe, to subsistence farmers and is the eldest of four boys. He immigrated to South Africa nearly ten years ago and started studying medicine as a way to fulfil his parents’ dreams. He eventually found his calling in internal medicine, specifically nephrology (kidney disease), and would like to obtain further qualifications in this field at the university. 

 “My achievements are the result of dedication to teaching internal medicine consultants. I am indebted to the Free State Department of Health for the opportunity to train and work under them. I hope to see great academic achievements within this province,” says Dr Mhundwa. 

He will graduate in April 2023 with a Master of Medicine, cum laude. His thesis was about The Prevalence of Chronic Kidney Disease Among Type 2 Diabetes Mellitus Patients in Central South Africa. 

Dr Mhundwa believes “that kidney disease is a scourge in modern society.  Early diagnosis is necessary to prevent patients from requiring kidney transplants and dialysis and to improve the quality of life of my patients”.

Prof Thabiso Mofokeng, Head of Department: Internal Medicine, said, “This achievement represents the UFS’ high academic standards on national front. We hope this is the first of many.”

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
