Cultural Options Because take all patch infection is favored by alkaline (pH ≥ 7.5) root zone soils, acidifying treatments may be effective in limiting the severity of patch development. These treatments involve using ammonium sulfate as a nitrogen source (when appropriate) during periods of pathogen activity.
