Relation of Witchweed (Striga) to Fertility in Tropical Soils [PDF]

Nature, 1953
MUCH is written upon the subject of soil exhaustion in Africa, and it seems to be generally accepted that the soils of the tropics require careful management, including frequent periods of rest, if fertility is to be maintained. In the great clay plains of the Sudan1 in particular, it has been emphatically stated that uncontrolled continuous ...

2D and 3D visualization of herbaceous plant–plant contact zones using high‐resolution X‐ray computed tomography (HRXCT)

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 367-381, March 2025.
Parasitic plants that deprive crops of water and nutrients are an increasingly concerning food security issue, affecting the livelihood of millions of subsistence, small‐ and mid‐scale farmers. An in‐depth understanding of parasite–host interactions is required to develop species‐specific and ecologically sustainable parasite management methods.

Management of witchweed, Striga hermonthica , and stemborers in sorghum, Sorghum bicolor , through intercropping with greenleaf desmodium, Desmodium intortum

, 2006
On-station and on-farm studies were conducted in western Kenya to assess the potential role of greenleaf desmodium, Desmodium intortum (Mill.) Urb., in a combined control strategy for witchweed, Striga hermonthica, and cereal stemborers in sorghum ...

The role of strigolactone structural diversity in the host specificity and control of Striga, a major constraint to sub‐Saharan agriculture

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 318-330, March 2025.
The parasitic weed Striga affects crops such as sorghum, maize, millet, and rice in over 40 countries on the African continent and negatively impacts the livelihood of over 300 million small‐holder farmers. Striga seeds can remain dormant in the soil for many years until they are triggered to germinate by germination stimulants, called strigolactones ...

Parasitic plants are models for examining global food security, biodiversity loss and host–parasite evolution, in a changing world

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 303-307, March 2025.
Parasitic plants, though often overlooked, are of exceptional importance and play a major functional role in the world's ecosystems. Where parasitic plants affect agricultural systems, they pose a threat to global food security at a time when this is already foreshadowed by a fast‐changing climate, a growing human population, economic volatility and ...

Bacteria as potential biocontrol agents for managing purple witchweed (Striga hermonthica) in grain sorghum [PDF]

Purple witchweed [Striga hermonthica (Delile) Benth.], a highly destructive parasitic weed, poses a significant threat to sorghum [Sorghum bicolor (L.) Moench] cultivation. This hemiparasitic plant intrudes its root system into the host plant, leading to

Ding dong the witch is (nearly) dead – the end is in sight for the Red Witchweed Eradication Program [PDF]

The first recorded detection of red witchweed in Australia occurred on a Mackay region sugarcane farm in July 2013. Following extensive delimitation surveillance, a total of eight neighbouring properties were confirmed as infested.

A potential role of heat‐moisture couplings in the range expansion of Striga asiatica

Ecology and Evolution
Parasitic weeds in the genera Orobanche, Phelipanche (broomrapes) and Striga (witchweeds) have a devastating impact on food security across much of Africa, Asia and the Mediterranean Basin.

A powerful molecular marker to detect mutations at sorghum LOW GERMINATION STIMULANT 1

The Plant Genome, Volume 18, Issue 1, March 2025.
Abstract The parasitic weed Striga (Striga hermonthica) limits productivity of sorghum (Sorghum bicolor) and other cereals in sub‐Saharan Africa and elsewhere. Improved host plant genetics is an effective control method but verified loci contributing to Striga resistance are limited.
