Worldwide, the competitive effect of weeds causes a 10% loss in agricultural production. Yield losses in rice and other grass crops in West Africa have been reported to range from 28-100% if weeds such as witchweed (Striga hermonthica) -a parasitic weed-are not controlled the greatest reductions occur on nutrient-poor soils. Left unchecked, weeds cause dramatic reductions in food production that eventually can... [Pg.32]

The parasite, Striga hermonthica, germinates in the presence of the root of its host angiosperm. A substance stimulating germination and having the properties of a ketopentose has been extracted from the root. D-xylu-lose was the most effective of the substances tested L-xylulose was inactive.
