Disease Severity on Cabbage Protected from Arthropod Pests with Insecticide Treated Agronets in Kenya

J. J. Kiptoo, M. Kasina, L. Wasilwa, M. Ngouajio, T. Martin, A. Too, J. J. Cheboi & P. W. Nderitu · Journal of Experimental Agriculture International · 2015

Cabbage (Brassica oleracea var. capitata L.) is one of the most important vegetables in Kenya, mainly grown by smallholder farmers for food and source of income. Its production is hampered by insect pests and diseases, leading to economic yield losses. Row cover insect proof nets...

Potential of Botanical Extracts in the Control of Kale Aphids (Brevicoryne brassicaea) and Their Effect on the Parasitic Wasp (Aphidius ervi)

Nderitu Wangari Peris & J. J. Kiptoo · Asian Research Journal of Agriculture · 2017

The use of synthetic pesticides has made important impacts on aphid control.  However, it has limitations due to the development of aphid resistance and negative effects on human health and the environment. In this research, we explore alternatives to pesticides by examining the...

Comparative Efficacy of Varied Concentrations Fipronyl in the Laboratory Management of Termites

Rotich Godfrey, Robert W. Nyukuri, Fredrick M. Wanjala, Nellie C. Oduor & J. J. Kiptoo · Chemical Science International Journal · 2015

Fipronyl are chemical formulations of phenyl pyrazole insecticide acting on the chloride channel of nervous system of insects to hinder chloride metabolism of γ- amino butyric acid of insect’s nervous system resulting in excess neuronal stimulation followed by death. It has good...
