Characterization of potato virus Y (PVY) isolates infecting solanaceous vegetables in KwaZulu-Natal (KZN), Republic of South Africa (RSA)
(2009)Potato virus Y (PVY) is an economically important virus worldwide. In South Africa, PVY has been shown to be a major limiting factor in the production of important solanaceous crops, including potato (Solanum tuberosum ... -
Chemical control of soybean rust (Phakopsora pachyrhizi) on soybeans.
(2005)Soybean rust (SBR) caused by Phakopsora pachyrhizi Syd. is an aggressive wind dispersed fungal disease which has spread around the world at an alarming rate in the last decade. The disease was first reported in South ... -
Control of insect-transmitted viruses in cucurbit crops in KwaZulu- Natal.
(1998)The production of cucurbits (Cucurbitaceae) in KwaZulu-Natal faces the constant threat of viral diseases. These can be so severe as to severely limit or prevent production in the latter part of the growing season ... -
Cultivation of exotic and local mushroom species for commercial production.
(1995)The project was undertaken primarily to determine the potential of growing Stropharia rugoso-annulata and Volvariella volvacea at a commercial level under South African conditions. Termitomyces umkowaani, an indigenous ... -

Development of a pepper (Capsicum annuum L.) hybrid variety with resistance to potato virus Y (PVY) using molecular breeding.
(2013)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 ... -
Development of an enzyme-linked immunosorbent assay (ELISA) for field detection and discrimination of Fusarium circinatum from Fusarium oxysporum and Diplodia pinea in pine seedlings.
(2013)Fusarium circinatum is a fungal pathogen that has had a serious impact on pine production throughout the world. It attacks most Pinus species including Pinus elliottii, Pinus patula and Pinus radiata. Infections in South ... -
Development of an integrated management approach to controlling bacterial speck of tomato.
(2015)Bacterial speck of tomato caused by Pseudomonas syringae pv. tomato (Pst) is an economically important bacterial diseases in many tomato growing regions worldwide. The development of bacterial speck epidemics is favoured ... -
Development of concentration and detection techniques for Cryptosporidium and Giardia and the significance of these protists in KwaZulu-Natal.
(1999)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 ... -
Development of free-living diazotrophic (FLD) inoculants and their effects on crop growth.
(2008)In this study several free-living diazotrophs (FLD) were isolated and screened for their nitrogen fixing ability on a range of crops grown in greenhouse, hydroponics and field trials. Rhizosphere isolates of free-living ... -
Development of fungal biological control of four agriculturally important pests, Sitophilus oryzae, Trialeurodes vaporariorum, Planococcus ficus and Eldana saccharina, in South Africa.
(2005)The use of entomopathogenic fungi to control agriculturally important pests, both in greenhouses and in the field, has been demonstrated by various authors for a number of years. This has been brought about by the ... -
Distribution, epidemiology and management strategies for Avocado sunblotch disease in South Africa.
(2017)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 ... -
