Witchweed: a Parasitic Weed of Grain Crops
Outlook on Agriculture, 1990The witchweeds, in the genus Striga, are a remarkable group of obligate flowering plant parasites, some of which attack and destroy the crops of small-scale farmers in many parts of the semi-arid tropics. Striga hermonthica devastates sorghum and millet crops grown in Burkina Faso, Cameroon, Chad, Ethiopia, Mali, Niger and Sudan, and the expansion of ...

Witchweed Control by Herbicides Translocated Through Host Plants
Weed Science, 1971Dicamba (3,6-dichloro-o-anisic acid) and 2,3,6-trichlorobenzoic acid (2,3,6-TBA) applied in lanolin pastes to leaves or roots of host plants growing in soil were translocated acropetally and affected witchweed (Striga lutea Lour.) plants parasitizing roots of host plants.

(+)-Strigol, a witchweed seed germination stimulant, from Menispermum dauricum root culture
Phytochemistry, 2003(+)-Strigol was isolated from Menispermum dauricum root culture filtrate. Its identity was confirmed by HPLC, 1H NMR, UV and MS, and on the basis of its CD spectrum. This is the first report on isolation of strigolactone from aseptic plant culture.

Mineral Nutrition and the Parasite-Host Relationship of Witchweed
Weed Science, 1971The influence of mineral nutrition on the parasite-host relationship of witchweed (Striga luteaLour.) and sorghum (Sorghum vulgarePers. ‘Texas Bighead’) was investigated in greenhouse and growth chamber studies. Sorghum was grown in Eustis loamy sand, either infested or not infested with witchweed, and treated with one of three levels of mineral ...
