Reaction of selected common bean genotypes to physiological races
(2011)
The wide pathogenic variability occurring in Phaeoisariopsis griseola, the causal agent of angular leaf spot of common bean (Phaseolus vulgaris L.), dictates that new sources of resistance be continuously identified. This ...
Plant parasitic nematodes associated with common bean in Kenya and the effect of Meloidogyne infection on bean nodulation
(1999)
A study to determine the distribution and population densities of plant parasitic nematodes associated with beans was undertaken in Kakamega, Kiambu, Machakos and Siaya districts of Kenya. Soil and root samples were taken ...
Effects of Canavalia ensiformis and Mucuna pruriens intercrops on Pratylenchus zeae damage and yield of maize in subsistence agriculture
(2006-06)
Host status of four leguminous cover crops [Canavalia ensiformis (L.) DC. (Jack bean), Crotalaria ochroleuca G. Don (Sunnhemp), Lablab purpureus L. (Hyacinth bean) and Mucuna pruriens (L.) DC. (velvet bean)] to Pratylenchus ...
Integrated management of root-knot nematodes in a tomato-maize crop system using the biocontrol fungus Pochonia clamydosporia
(University of Nairobi, 2015)
Integrated approaches are fast gaining popularity in the management of root-knot nematodes (RKN). This study was undertaken to assess the potential of integrating a biological control agent (BCA, Pochonia chlamydosporia ...
A review of the Amplified Fragment Length Polymorphism (AFLP) technique in genotyping and DNA fingerprinting studies
(2008)
Amplified fragment length polymorphism (AFLP) is a marker based on polymerase chain reaction
amplification of restricted fragments ligated to synthetic adaptors and amplified using primers which carry
selective nucleotides ...
Use of Repetitive Extragenic Palindromic (REP), Enterobacterial Repetitive Intergenic Consensus (ERIC) and BOX sequences to fingerprint Exserohilum turcicum isolates
(2010-04)
Objective: To examine the distribution of dispersed repetitive DNA (Enterobacterial Repetitive Intergenic
Consensus (ERIC), BOX, and Repetitive Extragenic Palindromic (REP) sequences in the genome of
Exserohilum turcicum ...
Assessing the role of organic soil amendments in management of rootknotnematodes on common bean, Phaseolus vulgaris L.
(2004)
A greenhouse study was conducted to determine the effectiveness of animal manures, cow and chicken manures, and green manures, Mucuna pruriens, Azadirachta indica and Tagetes minuta in root knot nematode suppression. The ...
Race Typing and Evaluation of Aggressiveness of Exserohilum turcicum Isolates of Kenyan, German and Austrian Origin
(2010)
Exserohilum turcicum the causal agent of northern corn leaf blight is a threat to corn production in
many areas of the world. The pathogen has a high genetic variability in terms of virulence, genetic structure
and several ...
Infectious structures and response of maize plants to invasion by Exserohilum turcicum (Pass). in compatible and incompatible host pathogen systems.
(2008)
Objective: To study the differential response of corn leaves to invasion by Exserohilum turcicum comparing compatible and incompatible host-pathogen systems. Methodology and results: Maize leaves excised from 14 day-old ...
Distribution of Turcicum leaf blight of maize in Kenya and cultural variability of its causal agent, Exserohilum turcicum
(2008)
The causal agent of Turcicum leaf blight Exserohilum turcicum was isolated from infected maize samples collected during a survey in seven districts representing the main maize growing areas of Kenya. The cultural variability ...
