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 ... -
The epidemiology and control of Capsicum viruses in Natal.
(1995)Virus diseases pose a serious threat to commercial pepper (Capsicum annuum L.) production in Natal. Following a survey of the principal capsicum-producing areas, potato virus Y (PVY) was found to be the predominant virus ... -
Maize root rot in South Africa.
(1995)Numerous fungal species are known to infect maize roots and eventually cause rot. The spectrum of fungi differs over localities as well as their relative frequencies. Fungi isolated from discoloured root tissue and root ... -
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 ... -
Factors affecting germination and growth of sugarcane transplants.
(1998)Transplants are produced and sold in South Africa for the planting of seedcane supply plots (nurseries), commercial fields, and for gap filling. The most important factor constraining the use of transplants is the low ... -
The epidemiology and control of crucifer chocolate spot.
(1998)In the 1991/92 season, a leaf spotting disease of crucifer seedlings appeared at a number of nurseries in Kwazulu-Natal (KZN) Province. Towards the end of 1996, the disease had also been detected in Western and Northern ... -
Utilization of Bacillus spp. as plant probiotics.
(2000)Numerous microorganisms produce beneficial effects on plant developmentwhen applied to crop seeds or incorporated into soil. Research efforts worldwide over the past two decades have renewed commercial interest in plant ... -
The metabolic fate of sucrose in intact sugarcane internodal tissue.
(2000)The study was aimed at determining the metabolic fate of sucrose in intact sugarcane internodal tissue. Three aspects of the fate of sucrose in storage tissue of whole plants formed the main focus of the work. These were ... -
Aspects of management of poplar rust in South Africa.
(2001)An assessment of infection on poplar clones grown at the Lion Match Company Redclyff Nursery in Seven Oaks, KwaZulu-Natal was made to ascertain the nature of infection of the three common species of Melampsora infecting ... -
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 ... -
Evaluation of growth media parameters for the cultivation of selected biological control agents.
(2002)Trichoderma harzianum kmd, Gliocladium virens MMI and Colletotrichum gloeosporioides C6 are potential biological control agents. Trichoderma harzianum kmd and and G. virens MMI have been shown to have excellent growth ... -
Evaluation of the potential use of antagonistic microbes on grass species, turf and pasture, for disease control and growth stimulation.
(2003)Public tendency, of late, is to reduce liberal use of harmful synthesized chemicals for promoting plant health. Today, biological control is becoming a commonly cited disease control option. Biological control agents ... -
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 ... -
The use of potato and maize disease prediction models using automatic weather stations to time fungicide applications in KwaZulu-Natal.
(2003)Maize grey leaf spot (GLS), caused by Cercospora zeae-maydis, and potato late blight (LB), caused by Phytophthora infestans, are foliar diseases of maize and potato, two of the most widely ... -
In vitro and in vivo screening of Bacillus spp. for biological control of Rhizoctonia solani.
(2003)The increasing concerns about chemical pesticides that are environmentally hazardous and the continuous development of resistance by palhogens to chemical pesticides have led to this study. Many studies have shown that ... -
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 ... -
Biocontrol of three fusarial diseases.
(2004)Over the past one hundred years, research has repeatedly demonstrated that phylogenetically diverse microorganisms can act as natural antagonists of various plant pathogens. Interest in biological control research continues ... -
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 ... -
Biological control of Phytophthora root rot of citrus seedlings and cuttings.
(2005)With an increasing realization that many agrochemicals are hazardous to animals and humans, came the desire to replace these chemical agents with biological approaches that are more friendly to the environment and human ... -
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 ...
