Development of a pepper (Capsicum annuum L.) hybrid variety with resistance to potato virus Y (PVY) using molecular breeding.
Pepper (Capsicum annuum L.) is an important vegetable crop grown and consumed worldwide. Potato virus Y (PVY) is a globally economically important pathogen which significantly reduces the yield and quality of cultivated ...
Weeds : reservoirs of vector-borne viral pathogens in South Africa.
Weeds have the potential to alter the function of ecosystems either as pests themselves or by harbouring vectors and vector-borne diseases. Their role as reservoirs of viral pathogens has had a significant bearing on viral ...
Integrated control of Fusarium head blight of wheat.
Fusarium head blight (FHB) is a destructive fungal disease of wheat (Triticum aestivum L) world-wide. There are no resistant cultivars currently available, nor are there any effective fungicides against FHB of wheat. The ...
Studies on Lecanicillium Muscarium as a Mycoparasite of the soybean rust fungus, Phakopsora Pachyrhizi.
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 ...
Distribution, molecular identification and the effect of biological control of phytophthora cinnamomi on macadamia in the Limpopo and Mpumalanga provinces, South Africa.
Macadamia is a nut-bearing tree that belongs to the family Proteaceae that consists of evergreen woody plants (Augstburger et al., 2002). The aboriginal tribes used the nuts as a staple food and as a base for medicines and ...
Distribution, epidemiology and management strategies for Avocado sunblotch disease in South Africa.
Avocado (Persia americana Mill.) is an economical important subtropical fruit worldwide. In the republic of South Africa (RSA) avocado contributes approximately 29% to the total gross value of subtropical fruits. Avocado ...
Genetic characterization, priming and screening for Cercospora leaf spot resistance of different Bambara groundnut (Vigna subterrannea [L.] Verdc.) landraces.
The Bambara groundnut (Vigna subterranea [L.] Verdc.) is an African plant species which has been cultivated for many years even longer than the groundnut (Arachis hypogaea L.). Bambara groundnut is mostly grown by farmers ...
Studies on the integrated control of the Russian wheat aphid, Diuraphis Noxia (Kurdjumov) (Hemiptera: Aphididae), using entomopathogenic fungi combined with sublethal doses of insecticides.
The Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), is one of the most damaging aphid pests of wheat grown under dryland conditions. Host plant resistance is considered as the most, cost-effective, ...
Investigating alternative methods to detect bovine mastitis in milk.
The aim of this study was to investigate alternate measures for the diagnosis of bovine mastitis, which can either be done separately or coupled with the current use of somatic cell counts. Techniques that were assessed ...
