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, ...
Genomics of quantitative resistance to brown rust (Puccinia melanocephala) in a sugarcane breeding population.
The Sugarcane Industry contributes approximately 400 000 jobs and ZAR 8 billion annually to South Africa’s economy. Due to climate change and the subsequent threat posed by disease, these figures have been on the decline. ...
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 ...
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 ...
Studies on Phakopsora pachyrhizi, the causal organism of soybean rust.
Phakopsora pachyrhizi H. Syd and P. Syd, the causal organism of soybean rust (SBR) was first reported in Japan in 1902. In 1934 the pathogen was found in several other Asian countries and as far south as Australia. In ...
Biological control of gray leaf spot (Pyricularia grisea (cooke) sacc.) of ryegrass.
Abstract available in PDF file.
Isolation and screening of freshly isolated bradyrhizobium and rhizobium spp. for multi-host plant growth promotion.
Biological nitrogen fixation (BNF) is an essential part of sustainable agriculture. Inorganic nitrogenous fertilizers are extensively used in modern, high input agriculture. However, they are expensive, and poorly absorbed ...
