Prof Moffett’s latest offering collates hundreds of mountain research material into one accessible reference book.

Prof Rodney Moffett recently published a new book focusing on various scientific articles published between 1808 and 2019. The book, A Scientific Bibliography of the Drakensberg, Maloti and Adjacent Lowlands, has 534 pages and covers material appearing in accredited journals, plus unpublished but traceable reports, documents, presentations, and dissertations.

“The scientific articles range from palaeobotany with 17 entries, to rock art with 502 entries, as well as 252 theses and dissertations,” said Prof Moffett.

He said it took 18 months to compile the book, typing the manuscript himself – mostly at night.

In the foreword, Dr Ralph Clark, Director: Afromontane Research Unit (ARU), says: “This bibliography is a labour of love, and will inspire a new generation to take up the baton for excellent research in this fantastic mountain system. We are proud to publish this under the ARU banner as a contribution to growing and consolidating mountain-passionate relationships in Southern Africa, and to encourage our journey towards developing a holistic understanding and sustainable use of these iconic mountain landscapes.” 

Other books

Prof Moffett is an honorary research fellow in the Department of Plant Sciences at the University of the Free State, and an associate of the Afromontane Research Unit on the UFS Qwaqwa Campus. He was previously Professor of Botany on the Qwaqwa Campus when it was part of the University of the North, retiring in 2000. Since then, he has remained active, publishing scholarly works on ethnobotany and other natural history subjects.

His four recent books, also published by Sun Press, are: Sesotho Plant and Animal Names and Plants used by the Basotho (2010), A Biographical Dictionary of Contributors to the Natural History of the Free State and Lesotho (2014), Basotho Medicinal Plants – Meriana ya Dimela tsa Basotho (2016), and A Field Guide to the Clarens Village Conservancy (2018). A second revised edition of Meriana ya Dimela tsa Basotho –

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
