Efficacy of Fusarium based mycoherbicide formulation against Striga hermonthica in sorghum

Abstract

Efficacy of a Fusarium oxysporum based mycoherbicide formulation (Pesta) was evaluated under field condition in a trial conducted in 2005 and 2006 cropping seasons. The mycoherbicide, spot- applied at 2g formulation per hill significantly reduced Striga count, infested crop stand (incidence) and increased number of wilted Striga plant, plant height, panicle and grain yield in both local and improved Sorghum varieties as compared with the same variety not treated with the mycoherbicide. The result demonstrated the efficacy of the granular formulation of Fusarium based mycoherbicide.
