Euphorbia Plant Extracts: The Solution to the Tomato Wilt Disease
Aloo, Nancy; Oluko, Patrick; Wanjohi, Bernard
Tomato is one of the most important vegetables in Kenya and plays a critical role in income generation and creation of employment for both rural and urban populations, in addition to meeting food nutritional
requirements. Tomato is a nutritious vegetable that provides good quantities of vitamins A and C. The crop
is grown for the domestic market under both rain-fed and irrigated conditions. Due to its high demand, most farmers have extensively adopted high-yielding varieties and modern technologies such as greenhouse production to ensure year-round and increased production. However, tomato farming is still threatened
immensely by several pests and disease, the most devastating of these being bacterial and fungal wilt
disease, with some farmers experiencing 80-100% yield losses per growing season. The objectives of the present study were to evaluate the potential of extracts of different plants (See Figure 2) against the tomato
wilt causing pathogens.

LEISHMANIA RESERVOIRS AND SANDFLY VECTORS : DANGERS IN CAVES
Makwali, Judith
Cutaneous Leishmaniasis occurs in the Highlands of Ethiopia and arid and semi arid regions of Kenya and Uganda, where increased human-fly contact occurs in villages built on rocky hills or river banks, which are the natural habitats of sand flies and hyraxes. Human cases of this disease have been reported in Mt. Elgon region (Mutinga 1975a) although no comprehensive study has been done to reveal its current prevalence, distribution, vector(s) and reservoir(s)status.
Conclusion
BACKGROUND INFORMATION
Information from the residents of Mt. Elgon reveals that Hyraxes, rats, Porcupines and bats are found in caves. Sand flies have also been found to breed in the caves. Itis estimated that the populations of the already implicated Leishmania reservoir hosts in this focus are currently too low due to loss of suitable habitats to maintain continuity of Leishmania transmission. Therefore the current reservoir(s) of the Leishmania species responsible for the maintenance of human cutaneous Leishmaniasis in Mt. Elgon focus are still unknown. Thus, this study investigated the role of bats and other animals found in the proximity of the caves in the maintenace and transmissionofthe Leishmania parasite in the region.

Enhancing Sustainability of Biogas Production in Kenya
Muturi, Samuel Mwangangi
Biogas is essentially a mix of gases and can be produced naturally and articially. In
natural conditions, the gas mainly methane is produced through wastes degradation
by microorganisms and enter into the environment. The high amount of methane in
biogas is what makes it valuable as an alternative energy source. However, when
released into the environment, the gas contributes to global warming. No appropriate
policy measures under environment and energy sectors that guide the rural poor on
how to dispose of the wastes. The worst is that the policy does not support the existing
digesters, further demolarizing the poor communities. Most of the stated policy
measures favor the urban richer communities, emphasizing on non-renewable
energies;
