Anaerobic growth chamber trials were conducted to evaluate effects of VFA and VFA concentration, and interactions with soil pH and soil texture, on A. rolfsii sclerotia germination. In the first objective, sclerotia were exposed to 4, 8, or 16 mmol/kg soil of acetic or n-butyric acids in sandy soil; soil pH was buffered to 5, 6, or 7. In the second objective, sclerotia in sandy or sandy loam soil were exposed to 4 or 16 mmol VFA/kg soil at soil pH 5 or 6. VFAs are probable important factors in A. rolfsii suppression due to ASD treatment in many soil environments, and activity is dependent on VFA concentration, soil solution pH, and soil texture.
