BACKGROUND: Recent reports indicate that organic fertilisers have a suppressive effect on the pathogens of plants grown under hydroponic systems. Furthermore, microorganisms exhibiting antagonistic activity to diseases have been observed in organic hydroponic systems. This study evaluated the effect of corn steep liquor (CSL) on controlling lettuce root rot disease [Fusariumoxysporum f.sp. lactucae (FOL)] in a hydroponic system. The effect of CSL and Otsuka A (a chemical fertiliser) on the inhibitionofFOLintermsofmycelialgrowthinhibitionwastestedinvivo.
RESULTS:AdditionofCSLsuppressedFOLinfectionrates.CSLinhibitedFOLinfectionby26.3–42.5%from2daysafterstarting incubation. In comparison, Otsuka A inhibited FOL growth by 5.5–19.4%. In addition, four of 10 bacteria isolated from the nutrientmediacontainingCSLexhibitedinhibitionzonespreventingFOLmycelialgrowth.
CONCLUSIONS: We found that CSL suppressed FOL in lettuce via its antifungal and biostimulatory effects. We suggest that activation of bene?cial microorganisms present in CSL may be used to decrease lettuce root rot disease and contribute to lettucerootgrowth.
