Infectious structures and response of maize plants to invasion by Exserohilum turcicum (Pass). in compatible and incompatible host pathogen systems.

Muiru, W M; Mutitu, E W; Kimenju, J W; Koopmann, B; Tiedemann, A V (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 ...

Dynamics of development of late blight [Phytophthora infestans] in potato, and comparative resistance of cultivars in the highland tropics

Olanya, O.M.; Ojiambo, P.S.; Nyankanga, R.O. (2006)

Host resistance is an important component for the management of late blight [Phytophthora infestans] on potato, in the highland tropics, where effective fungicide use is limited because of the cost of application. ...

Susceptibility of Kenyan wheat varieties to head blight, fungal invation and Deoxynivalenol accumulation inoculated with Fusarium graminearum

Muthomi, J W; Orke, E C; Dehne, H W; Mutitu, E W (2002)

Fifteen wheat varieties commercially grown in Kenya were tested for their susceptibility to head blight and mycotoxin accumulation after inoculation with Fusarium gramineanuu in pot experiments. The strain or the pathogen ...

Reaction of Some Coffea arabica Genotypes to Strains of Colletotrichum kahawae, the Cause of Coffee Berry Disease

Omondi, C.O.; Ayiecho, P.O.; Mwang'ombe, AW; Hindorf, H. (2000-01)

Pathogenicity tests were performed on 11 genotypes of Coffea arabica using single-isolate suspensions of Colletotrichum Kahawae obtained from 90 monoconidial isolates. The objective of this study was to estimate the ...

Identification of molecular markers linked to a gene conferring resistance to coffee berry disease (Colletotrichum kahawae) in Coffea arabica

Gichuru, E. K.; Agwanda, C.O.; Combes, M.C.; Mutitu, E.W.; Ngugi, E.C.K.; Bertrand, B.; Lashermes, P. (2008-12)

Coffee berry disease (CBD) caused by Colletotrichum kahawae is a major constraint to Arabica coffee (Coffea arabica) production in Africa. One source of resistance to the disease is a natural interspecific hybrid between ...

Susceptibility to IVM in a field strain of Haemonchus contortus subjected to four treatments in a closed sheep–goat flock in Kenya

Gatongi, P M; Njoroge, J M; Scott, M E; Ranjan, S; Gathuma, J M; Munyua, W K; Cheruiyot, H; Prichard, R K (2003)

Susceptibility to IVM (IVM) of “strain A” Haemonchus contortus which had been exposed to IVM four times over a 2-year period was compared to IVM susceptibility of “strain C” H. contortus which had no prior field exposure ...
