Striga hermonthica is a parasitic weed that causes significant yield losses in many important crops and affects the livelihood of millions of people worldwide. A study was undertaken to examine the effects of Desmodium, uncinatum (Jacq.) DC and D. dichotomum (Klein) DC root exudates on initiation of haustorium and attachment of S. hermonthica. A series of laboratory experiments was conducted at the Gezira Research Station, Wad Medani, Sudan. D. uncinatum and D. dichotomum root exudates, applied 24 hours subsequent to GR 24, a synthetic germination stimulant, or simultaneously with it, did not induce haustorium initiation. D. uncinatum and D. dichotomum curtailed striga attachment to sorghum roots
