The degree of loss depends on, crop and weed species present; timing and duration of competitive interactions; and resource availability (Agri 21 FAO*, IFIC 2004**). 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 * Agri 21 FAO: Agriculture 21.
Cumana, O. crenata, and O. ramosa). Results are compared with those obtained in the same bioassay with an internal standard, the synthetic analogue of strigol GR-24. A high specificity in the germination activity of SL on the sunflower parasite O. cumana has been observed, and a relationship between such activity and the high sunflower SL content is postulated. Molecular properties of the natural and synthetic germination stimulants (GR-24, GR-7, and Nijmegen-1) and SL have been studied using MMX and PM3 calculations.
