“…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.

“…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).…”

On-Farm trials were conducted from July to November during the 2009 and 2010 cropping seasons, at Tarka, Benue State, Nigeria to evaluate the effects of intercropping maize and soybean on striga control, grain yields and economic productivity. The treatments consisted of sole maize, sole soybean and the intercrop of maize and soybean, replicated three times in a randomized complete block design. The results obtained showed that intercropping maize and soybean significantly (P ≤ 0.05) reduced striga shoot count by 55.9 % and 56.1 % respectively, in 2009 and 2010 compared to that produced on pure maize plots. Number of affected maize plants, lodging score of maize and infestation rate were lower for intercropping than for sole maize plots. The severity level was also recorded lower for intercropping compared to that recorded for pure maize stands, where severity level is in the range of high to very high. Though, soybean yield was reduced by intercropping, however, soybean and maize intercropping system increased maize grain yield, total intercrop yield, land equivalent coefficient greater than 0.25, land equivalent ratio values greater than one (LER > 1), higher total intercrop values and monetary equivalent ratio greater than 1.00, indicating yield and economic advantages. The implication of study showed that intercropping maize and soybean can be adopted by farmers as an efficient cropping system strategy to reduce striga infestation, increase maize yield and give greater economic productivity.
