Understanding the present distribution of the parasitic weed Striga hermonthica and predicting its potential future geographic distribution in the light of climate change

Julius-Kühn-Archiv, 2012
Parasitic weeds of the genus Striga (Orobanchaceae) are a major constraint to agricultural production in the semi-arid regions in Sub-Saharan Africa. Therefore, Striga hermonthica’s current and future distribution needs to be estimated urgently in order ...

Screening of sorghum genotypes for resistance to Striga hermonthica and S. asiatica and compatibility with Fusarium oxysporum f.sp. strigae

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
In the semi-arid areas of Tanzania, yield losses of sorghum [Sorghum biocolor (L.) Moench] due to Striga hermonthica (Sh) and S. asiatica (Sa) infestations are estimated to be 30–90%.

The effect of Orobanche crenata infection severity in faba bean, field pea, and grass pea productivity.

Frontiers in Plant Science, 2016
Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area and West ...

Annual flower strips under the ‘Sweden Blossom’ initiative – how do they perform for pollinators, natural enemies and herbivores?

Agricultural and Forest Entomology, EarlyView.
Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.

Evaluation of fungal isolates as possible biocontrol agents against Striga hermonthica

Journal of Crop Protection, 2014
Striga hermonthica is a parasitic weed which largely constrains maize and sorghum production in Western Kenya. The weed mostly invades small scale farms and depending on severity, it may cause damage ranging from 10% to complete crop failure thereby ...

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Comparative gene expression analysis of differentiated terminal and lateral haustoria of the obligate root parasitic plant Phelipanche ramosa (Orobanchaceae)

Plants, People, Planet
Societal Impact Statements The parasitic weed Phelipanche ramosa thrives on a broad spectrum of cash crops over the Northern Hemisphere. Unfortunately, current management practices are inefficient in controlling its devastating impacts and spread.
