Identifying existing management practices in the control of Striga asiatica within rice–maize systems in mid‐west Madagascar

Ecology and Evolution, 2021
Infestations by the parasitic weed genus Striga result in significant losses to cereal crop yields across sub‐Saharan Africa. The problem disproportionately affects subsistence farmers who frequently lack access to novel technologies.

Combining ability of yield and yield components among Fusarium oxysporum f.sp. strigae-compatible and Striga-resistant sorghum genotypes

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2020
Use of sorghum [Sorghum bicolor (L.) Moench] cultivars with partial resistance to Striga spp. and Fusarium oxysporum f.sp. strigae (FOS) represents a novel strategy to control Striga.

Identification of Striga hermonthica-resistant Upland Rice Varieties in Sudan and Their Resistance Phenotypes

Frontiers in Plant Science, 2016
Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic.

Mapping quantitative trait loci and predicting candidate genes for Striga resistance in maize using resistance donor line derived from Zea diploperennis

Frontiers in Genetics, 2023
The parasitic weed, Striga is a major biological constraint to cereal production in sub-Saharan Africa (SSA) and threatens food and nutrition security.

Antifertility Activity of Striga orobanchioides.

Biological and Pharmaceutical Bulletin, 1994
Four successive solvent extracts of the whole plant Striga orobanchioides have been screened for antifertility activity in albino rats. Of these the ethanolic extract was found to be most effective in causing significant anti-implantation activity. The antifertility activity was reversible on withdrawal of treatment with the extract.

Prevalence and Socioeconomic Impact of Striga (Striga hermonthica) in Sorghum Producing Areas of East and West Hararghe Zones, Oromia, Ethiopia

International Journal of Agronomy, 2022
Striga is one of the biotic constraints limiting the production and productivity of sorghum in tropical Africa, particularly in Ethiopia. A field survey was conducted in the eastern and western Hararghe zones in six districts in the 2019 cropping season ...

Novel Sources of Witchweed (Striga) Resistance from Wild Sorghum Accessions [PDF]

, 2017
Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. Away from cultivated farmland, wild

Adoption of striga (striga hermonthica) Management Technologies in Northern Nigeria

Agrekon, 2016
This study examined the adoption of Integrated Striga Management (ISMA) technologies among maize farmers in Bauchi and Kano states of northern Nigeria. It employs a double-hurdle approach to analyse the factors influencing adoption and intensity of ISMA technologies among households, using cross-sectional data of 643 farmers from the two states.

Challenges to the exploitation of host plant resistance for Striga management in cereals and legumes by farmers in sub-Saharan Africa: a review

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
Striga hermonthica, Striga asiatica and Striga gesneroides are obligate root parasites that cause severe yield losses in cereals and legumes in sub-Saharan Africa. Genetic control of Striga through resistance is widely considered to be the most practical

Genetic variation and host-parasite specificity of Striga resistance and tolerance in rice: the need for predictive breeding [PDF]

, 2017
The parasitic weeds Striga asiatica and Striga hermonthica cause devastating yield losses to upland rice in Africa. Little is known about genetic variation in host resistance and tolerance across rice genotypes, in relation to virulence differences ...
