Application of transmissible agents to control citrus tree size.
(1997)Establishing citrus orchards at higher densities has become standard practice in South Africa. These plantings make more efficient use of inputs such as land, fertilizer, irrigation and spraying, and they are capable of ... -
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 ... -
Aspects of post-harvest seed physiology and cryopreservation of the germplasm of three medicinal plants indigenous to Kenya and South Africa.
(2002)The current state of global biodiversity is one of sustained and increasing decline especially in developing countries such as South Africa, where, medicinal plants face a particular threat due the herbal medicine trade, ... -
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 ... -
Biological and molecular characterization of South African bacteriophages infective against Staphylococcus aureus subsp. aureus Rosenbach 1884, casual agent of bovine mastitis.
(2012)Bacteriophage therapy has been exploited for the control of bacterial diseases in fauna, flora and humans. However, the advent of antibiotic therapy lead to a cessation of most phage research. Recently, the problem of ... -
Biological control and plant growth promotion by selected trichoderma and Bacillus species.
(2005)Various Trichoderma and Bacillus spp. have been documented as being antagonistic to a wide range of soilborne plant pathogens, as well as being plant growth stimulants. Successes in biological control and plant growth ... -
Biological control of fusarium wilt of pine seedlings using endophytic microorganisms and silicon.
(2015)Globally, pitch canker fungus (Fusarium circinatum) poses a serious threat to the softwood forest industry. In South Africa, F. circinatum has characteristically been a nursery pathogen, causing a seedling wilt, and has ... -
Biological control of gastrointestinal nematodes of small ruminants, using Bacillus thuringiensis (Berliner) and Clonostachys rosea (Schroers).
(2011)Gastrointestinal nematode parasites cause great losses in the production of small ruminants through reduced productivity and the cost of preventive and curative treatments. Because of the threat of anthelmintic resistance, ... -
Biological control of gray leaf spot (Pyricularia grisea (cooke) sacc.) of ryegrass.
(2017)Abstract available in PDF file. -
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 ... -
Biological control of the common house fly (Musa domestica L.) using Bacillus thuringiensis (Ishiwata) berliner var. Israelensis and Beauveria bassiana (Bals.) vullemin in caged poultry facilities.
(2008)The entomopathogenic fungus Beauveria bassiana and the bacterium Bacillus thuringiensis var. israelensis (Bti) have been widely studied for their role in biocontrol against many arthropods and extensively exploited for ... -
Biological control of the two-spotted spider mite, Tetranychus urticae Koch (Acari : tetranychidae).
(2009)The two-spotted spider mite (TSM), Tetranychus urticae Koch, is an important pest of many greenhouse and field crops worldwide. The development of resistance in TSM populations to chemical acaricides, allied with public ... -
Biological control of three grain storage pests: maize weevil, Sitophilus zeamais (Motschulsky), almond moth, Ephestia cautella (Walker) and cigarette beetle, Lasioderma serricorne (Fabricius), using novel strains of Beauveria bassiana (Balsamo) Vuillemin in powder formulation.
