“…This has provided the smallholder farmers with a diversity of options to control the parasites. Several researchers have extensively documented these potential options to combat Striga which have been classified into the most commonly used terms: cultural and mechanical control options including hand-pulling, crop rotation, trap-cropping, intercropping, appropriate improvement of soil fertility, and planting methods (Berner et al, 1995;Kuchinda et al, 2003;Hess and Williams, 1994;Hess and Dodo, 2004;Samake et al, 2006;Gworgwor, 2007;Khan et al, 2002Khan et al, , 2006Khan et al, , 2008Eltayb et al, 2013;Hooper et al, 2015); chemical control method such as application of chemical herbicides Kanampiu et al, 2007a;Kanampiu et al, 2007b) and biological control approaches using the pathogenic fungus Fusarium oxysporum as a mycoherbicide, or insects (Abbasher et al 1995(Abbasher et al , 1998Kroschel et al 1996;Marley et al, 1999Marley et al, , 2005Hess et al 2002;Elzein and Kroschel, 2004;Yonli et al, 2006;Zahran, 2008;Venne et al, 2009;Zarafi et al, 2015;Watson, 2013). Recently, the potential of the plant growth promoting rhizobacteria (PGPR) of the genus Bacillus (B. subtilis, B. amyloliquefaciens) and Burkholderia (B. phytofirmans) as Striga biocontrol agent has been surveyed by Mounde (2014).…”

“…Throughout much of the developed world, more technologically advanced solutions are preferred to combat S. asiatica, including biocontrol (e.g. Marley et al, 1999), herbicides (e.g. Marley and Shebayan, 2001) and methods of soil fumigation with ethylene gas (Gressel et al, 2004).…”

Learning to reduce degradation on Swaziland's arable land: enhancing understandings of Striga asiatica

2006

Maize production in Swaziland's middleveld is being increasingly threatened by the Striga asiatica weed (also called witchweed). It parasitises the maize crop to provide itself with water and nutrients, preventing the crop from growing properly. In this paper we examine the impacts of this bio-indicator of land degradation on rural livelihoods, investigating how farmers and policy makers are responding to the problem. Our results show that farmers' ability to control weed infestations is determined by a number of environmental, social and political-economic drivers and that national policies to reduce land degradation offer little assistance. Low-technology methods employed by farmers are an important step in alleviating the problem, but farmers' understandings of why these methods work are limited and they often neglect to combine control strategies. At the local level, there is a need to support farmer-to-farmer learning and education programmes to broaden and deepen farmer knowledge about S. asiatica. At the national level a more supportive policy context is necessary that recognises weeds as an indicator of a more serious overall land degradation problem, and which uses broader criteria to determine what constitutes land degradation. Without this attention, the threat from S. asiatica could increase in both area and intensity, with profound effects on both food security and the sustainability of rural livelihoods.

“…The potential of Fusarium oxysporum as a bio-control agent for the control of S. hermonthica in WCA has been reported (Ciotola et al, 1995;Diarra et al, 1996;Kroschel et al, 1996;Abbasher et al, 1998;Marley et al, 1999). Isolates of F. oxysporum from S. hermonthica have been shown to infect only Striga spp.…”

Fusarium oxysporum (isolate PSM 197) based mycoherbicide was evaluated for its efficacy under field conditions in trials conducted during 1999-2001 cropping seasons in the Nigerian savanna. In the 1999 cropping season, spot application of 5-10 g of mycoherbicide was found to give effective control of Striga hermonthica. Results of on-farm trials at Barhim and Dutsen-Ma areas showed the application of the mycoherbicide to significantly (p ¼ 0.05) increase stand count at both 3 weeks and at harvest, reduced Striga shoot count and increased crop yield in both improved and local sorghum varieties, as compared with the same varieties not treated with the mycoherbicide. Results establish the efficacy of F. oxysporum as a mycoherbicide and the need for further development of the mycoherbicide into formulated granules or seed treatment for use in control of S. hermonthica under field conditions.
