Isolation and molecular characterisation of tomato spotted wilt virus (TSWV) isolates occuring in South Africa.
Tomato spotted wilt virus (TSWV), a Tospovirus, is one of the ten most economically destructive plant viruses worldwide, causing losses exceeding one billion U.S. dollars annually on several crops. In South Africa (SA), ...
Studies on Sclerotinia sclerotiorum (Sclerotinia stem rot) on soybeans.
Soybeans, Glycine max, are an economically and strategically important crop in South Africa (SA). In order to meet local demands, large imports of soybeans are required, e.g., in the 2005/2006 soybean production period, ...
The development of transgenic sweet potato (Ipomoea batatas L.) with broad virus resistance in South Africa.
Sweet potato (Ipomoea batatas Lam.) is ranked as the seventh most important food crop in the world and its large biomass and nutrient production give it a unique role in famine relief. However, multiple virus infection is ...
A study on avocado sunblotch disease.
Avocado sunblotch disease is a graft-transmissible disorder known for over 60 years and has now been recorded in at least eight countries around the world. Affected trees develop yellow, depressed streaks on young ...
Studies on brown rust (Puccinia melanocephala) of sugarcane in South Africa.
The first serious outbreak of brown rust of sugarcane caused by Puccinia melanocephala Syd. & P. Syd. was reported in India in 1907. It was first reported in South Africa (SA) in 1941 on the variety Co301 and is now present ...
Identification and characterisation of some phytopathogens infecting South African indigenous ornamental plants.
South Africa is endowed with a large number of native plant species and many of the country’s plants have become important floricultural crops both locally and internationally. Three genera of South African monocotyledonous ...
Application of transmissible agents to control citrus tree size.
Establishing citrus orchards at higher densities has become standard practice in South Africa. These plantings make more efficient use of inputs such as land, fertilizer, irrigation and spraying, and they are capable of ...
Development of concentration and detection techniques for Cryptosporidium and Giardia and the significance of these protists in KwaZulu-Natal.
Cryptosporidium and Giardia are waterborne parasitic protozoons that have been associated with some diarrhoeal illness in most parts of the world. They are considered of major importance for drinking water safety as ...
Identification and characterization of viruses infecting cucurbits in the province of KwaZulu-Natal, Republic of South Africa, with the purpose of developing transgenic virus-resistant cucurbits.
The continued presence of cucurbit-infecting viruses across the Province of KwaZulu- Natal (KZN), South Africa requires exploration of alternative methods of controlling these viruses. The aim of this research project ...
