Onion as a Pest Control Intercrop in Organic Cabbage (Brassica oleracea) Production System in Ghana

Abstract: The use of chemical insecticides in the control of insect pests has left in its wake resistance of some pests to some of the conventional insecticides. Alternative methods of managing pests such as cultural control have to be employed to reduce pest infestation of crops. Onion was used in an intercrop as a non host crop to manage the pests of cabbage. The experiment was conducted in a Randomized Complete Block Design with four treatments; sole cabbage (T1), 2 rows of cabbage to 1 row of onion (T2), 3 rows of c… Show more

“…4.1Pest prevalence on cabbage plants at physiological maturity Pest prevalence was lower in intercropping treatments due to fewer Bemisia tabaci, Hellula undalis and Brevicoryne brassicae [6] that infested the intercropped plants than the sole crop. Garlic and onion are potentially effective in controlling pests on cabbages.…”
