Evaluation of integrated control of postharvest grey mould and blue mould of pome fruit using yeast, potassium silicate and hot water treatments.
(2012)The public concern over synthetic pesticides in foods and the environment has created an interest to find effective and safe non-fungicide means of controlling postharvest pathogens. The overall objective of this thesis ... -
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 ... -
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 ... -
Genetic characterization, priming and screening for Cercospora leaf spot resistance of different Bambara groundnut (Vigna subterrannea [L.] Verdc.) landraces.
(2017)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 ... -
Genomics of quantitative resistance to brown rust (Puccinia melanocephala) in a sugarcane breeding population.
(2012)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. ... -
Grain yield stability, genetic gain and path coefficient analyses in advanced soybean (Glycine max (L.) Merr.) lines.
(2017)Zambia is among the top 20 leading global producers of soybean (Glycine max L. Merr.) but adequate production is still hampered by low productivity. The yields of soybean in Zambia average below 3.0 t/ha against a yield ... -
Identification and characterisation of some phytopathogens infecting South African indigenous ornamental plants.
(2014)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 ... -
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 ... -
Integrated control of Fusarium head blight of wheat.
(2015)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 ... -
Integrated management of early blight of tomato caused by alternaria solani.
(2016)Abstract available in PDF file. -
Integration of rapid hot water treatments and biocontrol agents to control postharvest pathogens of tomato.
(2019)Anthracnose and sour rot caused by Colletotrichum and Galactomyces (syn. Geotrichum) species, respectively, are major fungal postharvest pathogens causing significant losses of tomato fruit. The growing public concern ... -
Investigating alternative methods to detect bovine mastitis in milk.
(2018)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 ... -
Investigating induced resistance in sugarcane.
(2013)Five potential resistance-inducing chemicals were applied to two sugarcane varieties (N12 and N27) in a pot trial with the aim of inducing resistance to nematodes in naturally-infested soil. BION® (acibenzolar-S-methyl), ... -
Investigating the effect and efficiency of steel slag as a source of silicon for plant uptake.
(2021)Silicon (Si) is the second most abundant element on the planet, after oxygen, making about 25% of the Earth's crust. Since it exists in the Earth’s crust, many plants can accumulate it in large concentrations, in amounts ... -
Investigation of rootstocks for seed production in Eucalyptus nitens.
(2013)Rootstock age and size, combined with nutrients, temperature, and humidity are major factors thought to play an important role in grafting success in eucalypts. Research was conducted on the grafting success of interspecies ... -
Isolation and molecular characterisation of tomato spotted wilt virus (TSWV) isolates occuring in South Africa.
(2006)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), ... -
Isolation and screening of freshly isolated bradyrhizobium and rhizobium spp. for multi-host plant growth promotion.
(2016)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 ... -
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 ... -
Management of aspergillus flavus link infections in groundnut seeds using hot water treatment and biological control agents.
(2021)Groundnut (Arachis hypogaea L.) is the 13th most important crop and classified as a cash flow crop. Groundnuts’ economic importance includes food and fodder purposes in the agriculture and food industries. The major ... -
Marker-assisted selection for maize streak virus resistance and concomitant conventional selection for Downy Mildew resistance in a maize population.
(2013)Maize streak virus (MSV) disease, transmitted by leafhoppers (Cicadulina mbila, Naude), and maize downy mildew (DM) disease caused by Peronosclerospora sorghi (Weston and Uppal) Shaw, are major contributing factors to low ...
