(University of Nairobi, 2017)
Theeffects of 2 Neem derivatives, Neem oil (NO) and Neem Seed Powder (NSP),on various physiological parameters of the brown ear tick, Rhipicephalus appendiculatus,the vector for Theileria parva. ...
The Effect Of Essential Oils Of Tagetes Minuta And Tithonia Diversifolia On On-host Behaviour Of The Brown Ear Tick Rhipicephalus Appendiculatus
(University of Nairobi, 2018)
On-host behaviour of Rhipicephalus appendiculatus was studied in the field in Bungoma County in Kenya to evaluate the putative repellent effects of essential oils of Tagetes minuta and Tithonia diversifolia at its predilection ...
Contribution of Seed Quality to the Occurrence of Fungal and Bacterial Diseases of Farmer Produced Common Bean in Varied Agro-Climatic Zones of Western Kenya
(University of Nairobi, 2018)
Abstract: Farmers often recycle farm saved bean seeds from previous harvest for planting in subsequent cropping seasons
resulting in reduced quality and buildup of seed borne diseases. This study investigated the quality ...
