Antifungal activity of endophytes from arctotis arctotoides (l.f.) o. hoffm against pythium and rhizoctonia root-rot diseases of maize (zea mays L.)
(2021)Maize (Zea mays L.) is one of the predominant crops worldwide, together with wheat (Triticum aestivum L.) and rice (Oryza sativa L.). Approximately 60% of maize produced in South Africa is white maize and is a staple food ... -
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 ... -
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 characterization of South African bacteriophages infective against Streptococcus uberis, a causal agent of bovine mastitis.
(2019)Mastitis is an inflammatory disease of bovine mammary glands and is the most economically important disease affecting dairy herds in South Africa, and globally. The incidence and history of mastitis in South Africa has ... -
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 head rot and damping-off of sunflower using yeasts, Bacillus spp. and Trichoderma spp.
(2021)The soil-borne fungi Sclerotinia sclerotiorum, Sclerotium rolfsii and Rhizoctonia solani are ubiquitous plant pathogens with a wide host range. They are among the most widespread pathogens, and cause destructive diseases ... -
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 root knot nematodes (meloidogyne spp.) using bacterial and fungal antagonists.
(2014)Root-knot nematodes are an important pest of many crops worldwide. Chemical nematicides are the main control methods used to reduce damage caused by nematode pests on crops. However, there are aims of reducing the use of ... -

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 ... -
