Abstract
Striga (witchweed) is one of the most important pests that affect food production in the tropics. In Kenya, the parasite is a serious pest that mainly threatens maize production. Yield losses are between 65 and 100%. With increasing demographic pressure and demand for food, there has been intensification of land use, mono cropping and consequently a decline in soil fertility. This depletion of soil fertility is one of the main causes for the increase in Striga incidence (Ransom, 1996).
