THE PARASITISM OF STRIGA HERMONTHICA BENTH. ON LEGUMINOUS PLANTS
Annals of Applied Biology, 1947Pot experiments at the Gezira Research Farm showed that Striga hermonthica Benth. is not confined to the Gramineae but can also parasitize groundnuts, cowpea, dolichos bean and soya bean, causing a loss in yield in all but the last‐named. The Striga plants developing on the roots of these hosts were small, apparently ill‐nourished and did not grow more

A transcriptome atlas of Striga hermonthica germination
2022Abstract Societal Impact Statement Witchweeds, parasitic plants of the genus Striga , are nicknamed “cereal killers” because of their devasting destruction of Africa’s most staple cereals, including maize, sorghum, millets, and upland rice.

Treatment of conditioned seeds of four isolates of Striga hermonthica and one isolate of Striga aspera with various concentrations of the ethylene precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), caused complex stimulation of germination patterns.

Small-molecule antagonists of germination of the parasitic plant Striga hermonthica
Nature Chemical Biology, 2016Striga spp. (witchweed) is an obligate parasitic plant that attaches to host roots to deplete them of nutrients. In Sub-Saharan Africa, the most destructive Striga species, Striga hermonthica, parasitizes major food crops affecting two-thirds of the arable land and over 100 million people.

Influence of triclopyr and nitrogen on management of Striga hermonthica on sorghum
World Journal of Science, Technology and Sustainable Development, 2015Purpose – The purpose of this paper is to study the effects of the herbicide triclopyr, nitrogen and their combinations on Striga incidence and sorghum growth. Design/methodology/approach – A greenhouse study was undertaken in season 2013.

Pathogenicity of fungi collected in northern Ghana to Striga hermonthica
Weed Research, 1996SummaryThirteen fungal species were isolated from diseased plants of Striga hermonthica (Del.) Benth in northern Ghana. The pathogenicity of 12 isolates of the fungal species including Curvularia fallax Boed, Fusarium equiseti (Corda) Sacc., Fusarium equiseti var. bullatum (Sherb.) Wollenw., F. oxysporum Schlecht, F.

Expression of mature plant resistance to Striga hermonthica in maize
Euphytica, 2000Twelve maize genotypes with different degrees of resistance were evaluated in plots inoculated with seeds of the phytoparasite Striga hermonthica (Del.) Benth. and in Striga-free (control) plots for three seasons between 1991 and 1993. Resistant genotypes, although showing similar levels of underground infection as susceptible 9 weeks after maize ...

Striga hermonthica (Scrophulariaceae: Rhinanthoideae) is aparasitic weed on sorghum and millet in Africa. It has not been possible, so far, to breed varieties of these crops immune to striga. Variation in many floral and vegetative features and in seed coat ornamentation indicates a diversity of genotypes within populations of hermonthica.
