Plant And Cell PhysiologyAbstract Broomrapes (Phelipanche and Orobanche spp.) and witchweeds (Striga spp.) are parasitic weeds that are increasingly threatening crops worldwide. Seeds of these species rely on host-derived signals such as strigolactones (SL) to germinate.

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 ...

Selectivity of Pyriclor on Witchweed, Tobacco, and Other Plants
Weed Science, 1971Postemergence directed application of 0.56 kg/ha of 2,3,5-trichloro-4-pyridinol (pyriclor) gave control of witchweed (Striga lutea Lour.) equivalent to 2.24 kg/ha of (2,4-dichlorophenoxy)acetic acid (2,4-D) without injuring corn (Zea mays L.). Pyriclor applied to the soil surface or incorporated did not significantly injure tobacco (Nicotiana tabacum L.

Control of Witchweed, Striga hermonthica Benth., in the Sudan Gezira
Nature, 1957RECENT work1 has shown that the phanerogamic root parasite Striga hermonthica Benth. (witchweed), which causes considerable crop losses to sorghum (Sorghum vulgare Pers.) in the Sudan and elsewhere, can be controlled by spraying the young crop with hormone weed-killers of 2,4-D type two to three weeks after sowing.
