The obligate hemiparasite Striga hermonthica is one of the major global biotic threats to agriculture in sub-Saharan Africa, causing severe yield losses cereals. germination seeds relies on host-released signaling molecules, mainly strigolactones (SLs). This dependency opens up possibility deploying SL analogs as "suicidal agents" reduce accumulated seed bank infested soils. Although several synthetic have been developed for this purpose, utility these compounds realizing suicidal strategy...
Striga hermonthica, a member of the Orobanchaceae family, is an obligate root parasite staple cereal crops, which poses tremendous threat to food security, contributing malnutrition and poverty in many African countries. Depleting seed reservoirs from infested soils one crucial approaches minimize subterranean damage crops. The dependency germination on host-released strigolactones (SLs) has prompted development "Suicidal Germination" strategy reduce accumulated bank Striga. success...
At the onset of COVID-19, researchers quickly recognized need for research on consequences pandemic agricultural and food systems, both in terms immediate impacts access to inputs labor, disruptions transportation markets, longer-term implications crop productivity, income, livelihoods. Vegetable production supply chains are particularly vulnerable due perishable nature products labor-intensive practices. The purpose this study was understand COVID-19 vegetable Burkina Faso biophysical...
Abstract BACKGROUND Striga hermonthica , an obligate root parasitic weed, poses a significant threat to cereal production in sub‐Saharan Africa. Lowering seed bank infested soils is promising strategy mitigate infestation levels. The dependency of germination on strigolactones opens up the possibility ‘suicidal germination’ approach, where synthetic stimulants induce lethal absence host. Implementing this approach requires active with suitable formulation for field application. Here, we...
Resilience of smallholder farmers in their ability to bounce-back and overcome shocks, such as drought, is critical ensure a pathway out hunger poverty. Efficient water conservation methods that increase rainwater capture reduce soil erosion stone lines grass bands are two technologies have been proposed the resilience Sudano–Sahelian farming systems. In Burkina Faso, we show lines, bands, crop rotation effective strategies individually combination. During years when rainfall...
Summary Striga hermonthica is a destructive parasite of cereal crops in the semi‐arid tropical zone. Two greenhouse experiments were conducted at Kamboinsé, Burkina Faso, to investigate effect inoculum substrate and location seeds on ability 14 indigenous Fusarium isolates control parasite. In Expt 1, reduced emerged number, vigour dry biomass. As result, sorghum biomass grain yield enhanced. Inoculum did not influence . 2, isolates, their interaction significantly influenced germination...
A 2-year (1997–1998) study was conducted at Kouaré, Burkina Faso, to investigate effect of growth medium and application method Fusarium oxysporum isolate 4-3-B control Striga hermonthica. In 1997, delayed striga emergence by 9 days. Isolate reduced emerged number 33% compared treatments without Fusarium. 1998, 13 days The fungus the 27% and, as a result, sorghum straw grain yields were significantly improved 10 38%, respectively.
This study was conducted to evaluate the allelopathic properties of endogenous plant species against Striga hermonthica (Del.) Benth., a root parasitic weed. In this respect, twenty five water extracts and eight freeze dried from sixteen were screened in bio-assays test their ability induce or inhibit germination S. seeds. seeds conditioned either 10% diluted lyophilisats check inhibition effect on seed germination. Three doses, 1, 5 applied Aqueous four reduced by 95.8 99.8% compared...
Abstract Background The genus Striga includes 11 parasitic plants species of food crops in at least 50 African countries. hermonthica (Del.) Benth. is a major biotic constraint to the cereal production Africa. It most widespread fields Burkina Faso and grows on all types soil inducing losses estimated 35–40% sorghum millet. substantial reductions yield caused by S. contribute significantly an insufficient supply for populations area. Methods This study aims identify local with bio-herbicidal...
A two-year field study investigated integrated management of Striga hermonthica on sorghum through host crop resistance, biocontrol (Fusarium oxysporum isolate 34-FO), and fertilizer application. The experiment was conducted in a with natural infestation at Kouaré Research Station Fada N’Gourma, Burkina Faso. Treatments combining resistance Fusarium inoculum N-fertilizer or manure significantly reduced emerged plant number, vigour dry biomass the area under number progress curve...
The continuous degradation of agroecosystems is a major concern for Sub-Saharan African countries, particularly Burkina Faso. To fight against this problem, various research projects and programs have implemented Soil Water Conservation practices (SWC) in Northern objective study was to assess the economic performance stone rows, grass strips, zaï, filtering dikes, half-moons agroforestry on agricultural production part Stochastic Frontier Analysis used estimate SWC’s technical efficiency....
Striga species affect the potential productivity of cereals in sub-saharian Africa due to lack durable Striga-resistance host crops. This study aimed at inducing new source resistance sorghum using gamma irradiation. Dry seeds three Sorghum varieties; Grinkan, ICV1049 and Sariaso14 were gamma-irradiated with 200 Gy, 300 400 Gy 500 Gy. Screening strategies involved a 2-year field greenhouse experiments, where mutant families, their parents resistant control artificially infected hermonthica...
