Conventional and biotechnological approaches for control of parasitic weeds (2007, background): “Preemergence herbicides (soil applied before crop emergence), such Compiled from Aly et al. (2003), Gressel et al. (2004), Lanini 2004, Lee and Timmons 1956. a Loss includes sorghum, millets, and maize. b Loss of legumes only c Loss of volume growth in lodge pole, pine, and western larch trees…”
Combined control of Striga hermonthica and stemborers by maize-Desmodium spp. intercrops (2006, background): “Striga infestation continues to extend to new areas as farmers abandon heavily infested fields for new ones (Khan, 2002; Gressel et al., 2004).”
Innovations in parasitic weeds management in legume crops. A review (2011, background): “The engineering of hypervirulence genes into weed-specific pathogens is receiving increasing attention (Gressel et al. 2004).”
The role of flavonoids in root-rhizosphere signalling: opportunities and challenges for improving plant-microbe interactions. (2012, background): “The parasitic weed Striga constitutes one of the major problems in African agriculture, with yield losses up to 100% in large parts of sub-Saharan Africa, thus inhibiting its germination would be an important achievement (Gressel et al., 2004).”
On-farm evaluation of the 'push-pull' technology for the control of stemborers and striga weed on maize in western Kenya (2008, background): “S. hermonthica infestation continues to extend to new areas in the region as farmers abandon heavily infested fields for new ones (Khan, 2002; Gressel et al., 2004).”
Faba bean breeding for resistance against biotic stresses: Towards application of marker technology (2006, background): “Losses in faba bean caused by broomrape are estimated to range from 50% to 80% in fields with medium and high levels of infestations, respectively (Gressel et al., 2004).”
