Effects of water stress on growth and water relations of young grafted tea.
(Tea Research Foundation of Kenya, 2009)The effects of soil water stress on some physiological parameters and dry matter partitioning (dm) were studied in grafted tea plants (Camellia sinensis L.) grown in containers and subjected to adequate and reduced water ... -
Effects of weed control methods on weeds and productivity of range grasses in semi-arid Kenya
(Tropical and Subtropical Agroecosystems, 2023)Background: Weeds are a common occurrence and challenge in different crops eventually influencing crop development and yields. Weed control and management are key in enhancing the productivity of cultivated pastures. In ... -
The effects of zeolite x and y on degradation kinetics of P, P'-DICHLORODIPI-IENYLYTRICIILOROETHANE (DOT) in natural water
(Maseno university, 2010)The study was on degradation kinetics of pesticides in water by zeolites. Pesticides are never target specific and as such, aerial dissipation of pesticides is potentially \ hazardous to man and environmental biodiversity. ... -
Effects of zeolite X on dissipation of hexazinone from agricultural waste waters in Western KenyaEffects of zeolite X on dissipation of hexazinone from agricultural waste waters in Western Kenya
(2013)Dissipation of hexazinone in Zeolite X treated wastewater followed pseudo first-order kinetics giving a calculated half-life of 41 days compared to a half-life of 144 days in untreated wastewater. The herbicide degraded ... -
Effects of zeolites X and Y on the degradation of malathion in water
(2013)The inclusion of both zeolites X and zeolite Y significantly affected the dissipation of malathion in water. In the fresh water, malathion degradation followed a pseudo-first order kinetics with concomitant half-life ... -
Effects, of some terrestrial weeds, termites and snails on growth and yield of the cichlid fish oreochromis niloticus L.
(Moi University, 1998-08)The major aim of aquaculture (farming and husbandry of fish and shellfishes) is to boost the production of fish in ~the attempt <...to satisfy human need for food and protein. qne of the most important challenges in any ... -
Efficacy and persistence of long-lasting microbial larvicides against malaria vectors in western Kenya highlands. Parasites & Vectors
(2018)ackground: Chemical-based malaria vector control interventions are threatened by the development of insecticide resistance and changes in the behavior of the vectors, and thus require the development of alternative control ... -
Efficacy of Chlorfenapyr and Clothianidin Insecticides on Anopheles Malaria Vector populations of Nyando, Bumula and Ndhiwa sub-counties, Western Kenya
(Maseno University, 2018)Malaria is a global health problem resulting in 435,000 deaths annually with 90% of the deaths occurring in sub-Saharan Africa. Over 70% of the Kenyan population is at risk of malaria and western Kenya is an endemic region ... -
Efficacy of long lasting insecticidal nets compromised by insecticide resistance
(Research Information Ltd, 2014-01-01)Malaria control is heavily reliant on the use of insecticides given that the two most common control tools, long lasting insecticidal nets (LLIN) and indoor residual sprays are both insecticide based. Of these, the ... -
Efficacy of long lasting insecticidal nets compromised by insecticide resistance

The efficacy of long-lasting nets with declining physical integrity may be compromised in areas with high levels of pyrethroid resistance
(BioMed Central, 2013)Background Long-lasting insecticide-treated mosquito nets (LLINs) are a primary malaria prevention strategy in sub-Saharan Africa. However, emergence of insecticide resistance threatens the effectiveness of LLINs. Me ... -
Efficacy of mycotoxin binder on aflatoxin M1 and Mazzican on total bacterial count in raw milk among smallholder dairy farmers in Kisumu County, Kenya
(ILRI, 2019-05-20)Background: Worldwide, milk forms a major part of human diet especially for children and expectant mothers. However, milk in East Africa has been shown to be frequently contaminated with aflatoxin M1 (AFM1) and bacteria. ... -
