Dietary aflatoxin exposure and impaired growth in young children from Kisumu District, Kenya: Cross sectional study
(School of Biological Sciences, 2004)Cereal grains are the basis of weaning gruel in Kenya yet they run a high risk of mycotoxin contamination. Children could be at a higher risk of dietary mycotoxin exposure than the rest of the population. This paper presents ... -
Land use systems and distribution of trichoderma species in Embu
(School of Biological Sciences, 2007)The distribution of Trichoderma species in soils of Embu region in relation to land use practices was investigated. The study area was chosen because of its significant land use intensification. Soil washing and dilution ... -
Influence of soil chemical and physical properties on occurrence of trichoderma spp. in Embu, Kenya
(School of Biological Sciences, 2009)Soil samples were collected from eight land use types in Embu to assess the effects of land use on soil chemical and physical parameters and their impact on occurrence of Trichoderma spp. The fungus was recovered from the ... -
Influence of soil chemical and physical properties on Trichoderma spp occurrence in Taita region
(School of Biological Sciences, 2009)Agricultural intensification has been cited as one of the causes of loss of biodiversity. Taita Taveta, a coastal highland region is such like area which has experienced land conversion from forest cover into farmlands ... -
Ecologists can enable communities to implement malaria vector control in Africa
(Department of Zoology, 2006)Integrated vector management (IVM) for malaria control requires ecological skills that are very scarce and rarely applied in Africa today. Partnerships between communities and academic ecologists can address this capacity ... -
Effect of trichoderma harzianum and arbuscular mycorrhizal fungi on growth in tomato (lycopersicum esculentum mill) seedlings, napier (pennisetum purpureum l) and tea (camellia sinensisl) cuttings
(School of Biological Sciences, 2009)A green-house study was conducted to investigate the ability of an isolate of Trichoderma harzianum (P52) and arbuscular mycorrhizal fungi (AMF) in enhancing growth in tomato seedlings, tea and napier grass cuttings. The ... -
Evaluation of selected soil fertility management interventions for suppression of fusarium spp. in a maize and beans intercrop
(School of Biological Sciences, 2011)Fusarium root rot of maize and beans is a common problem in Taita District, Kenya causing economic losses to the small scale farmers. The pathogen attacks maize and beans at all growth stages causing rot at the seedling ... -
Antagonism of Trichoderma farzianum isolates on soil borne plant pathogenic fungi from Embu District, Kenya
(School of Biological Sciences, 2010)Species in the genus Trichoderma are important as commercial source of several enzymes and as biofungicides/growth promoters. The most common biological control agents of the genus are strains of T. harzianum, T. viride ... -
Improved seedling emergence and growth of maize and beans by Trichoderma harziunum
(School of Biological Sciences, 2011)An indigenous strain of Trichoderma spp. was tested for its ability to promote seed germination and growth of maize and bean seedlings grown in the field at Embu District, Kenya. The trial was carried out for three seasons ... -
Inoculation of tomato seedlings with Trichoderma Harzianum and Arbuscular Mycorrhizal Fungi and their effect on growth and control of wilt in tomato seedlings
(School of Biological Sciences, 2011)A green house study was conducted to investigate the ability of an isolate of Trichoderma harzianum (P52) and arbuscular mycorrhizal fungi (AMF) in enhancing growth and control of a wilt pathogen caused by Fusarium oxysporum ... -
Pesticide Residues in Beef and Camel Meat From Slaughterhouses in 13 Districts in Kenya
(Department of Public Health, Pharmacology and Toxicology, 2009)One hundred and fifty one beef (n=136) and camel (n=15) meat samples comprising mainly of adipose tissue were collected from animals slaughtered in 13 districts in Kenya for analysis of organophosphate and organochlorine ... -
Farmer Perceptions on Indigenous Pig Farming in Kakamega District, Western Kenya
(Department of Public Health, Pharmacology and Toxicology, 2010)Objectives for this paper were to: study farmer beliefs and perceptions on local pig farming practices; and to explore opportunities for improved located production in selected villages of Western Kenya. The paper seeks ... -
Macroinvertebrate fauna of water hyacinth in the Kenyan waters of Lake Victoria.
(School of Biological Sciences, 2000)The macro-invertebrate fauna on water hyacinth in Kenyan waters of Lake Victoria was surveyed by collecting samples from 5 major ecological zones of the lake. Insecta, Oligochaeta, Hirudinea, Arachnida, Gastropoda and ... -
Impact of land use on the distribution and diversity of entomopathogenic nematodes in Embu and Taita districts, Kenya
(2011)Natural entomopathogenic nematodes (EPNs) are considered as potential biological control agents against soil-borne insect pests. This study was conducted to determine the impact of land use on the distribution, occurrence ... -
The KRISP 94 lithospheric investigation of southern Kenya — the experiments and their main results
(Department of Geology, 1997)Following two previous experiments in 1985 (KRISP 85) and 1989–1990 (KRISP 90), a series of geophysical experiments was undertaken in 1993–1995 (KRISP 94) to study the lithospheric structure of the southern Kenya rift down ... -
