Response of the endangered medicinal plant : Siphonochilus aethiopicus (Schweif) B.L. Burt. to agronomic practices.
(2011)This study examines field cropping constraints for domestication of an endangered, wild medicinal plant, Siphonochilus aethiopicus, (Schweif.) B.L. Burt. Extensive literature review and careful observations of plant growth ... -
Seed-borne pathogens and the bean weevil (Acanthoscelides obtectus) in bean (Phaseolus vulgaris) seed and their effect on seed germination and vigour.
(2003)Two semi-selective media, MT and MSP, were compared for their ability to recover cells of the bacteria Xanthomonas axonopodis pv. phaseoli (Xap) and Pseudomonas syringae pv. phaseolicola (Psp), the causal organisms of ... -
Shoot apex culture of Acacia mearnsii (De wild)
(2007)Research into the micropropagation of black wattle in South Africa is important for two reasons. Firstly micropropagation technology allows breeders to select and propagate mature tissue, which in turn allows them to better ... -
Studies of integrated control of selected root diseases of sunflowers using Trichoderma harzianum (ECO-T®) and silicon
(2009)The soil-borne fungi Rhizoctonia solani Kuhn and Sclerotinia sclerotiorum De Bary are ubiquitous plant pathogens with a wide host range. They are among the most widespread and destructive diseases of many crops, including ... -
Studies on brown rust (Puccinia melanocephala) of sugarcane in South Africa.
(2009)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 ... -
Studies on Lecanicillium Muscarium as a Mycoparasite of the soybean rust fungus, Phakopsora Pachyrhizi.
(2017)Soybean rust (SBR) is the most damaging foliar disease in many soybean growing areas of the World. Fungicide sprays seems to be the only method available for SBR control. An alternative to fungicides is needed, considering ... -
Studies on Phakopsora pachyrhizi, the causal organism of soybean rust.
(2006)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 ... -
Studies on Sclerotinia sclerotiorum (Sclerotinia stem rot) on soybeans.
(2007)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, ... -
Studies on the application of biocontrol agents for the control of seedling diseases.
(2002)The controlled environment of greenhouses, the high value of crops, and the limited number of registered fungicides offer a unique niche for the biological control of plant diseases. During the past ten years, over 80 ... -
Studies on the biocontrol of seedling diseases caused by Rhizoctonia solani and Pythium sp. on sorghum and tef.
(2003)Rhizoctonia solani and Pythium spp. are aggressive soil-borne fungal pathogens responsible for seed rot and seedling damping-off of many crops. With increased environmental and public concern over the use of ... -
