小麦籽粒产量下降，因为在具有相同分蘖数的植物中，普通根腐病的症状变得更加严重。这种趋势在大麦中并不那么明显。然而，随着季节的推移，分蘖最少的大麦植株的普通根腐病症状最为严重。此外，在小麦和大麦等分蘖最少的植物上，疾病的严重程度增加得更快。该病害对减产的主要影响是病害较多的植物产生较少的分蘖。较小的影响是，随着具有相同分蘖数量的植物疾病的增加，每株植物的谷物产量下降，这表明常见的根腐病会降低单个分蘖的产量。
Wheat grain yield decreased as symptoms of common root rot became more severe in plants with the same number of tillers. This trend was not as obvious in barley. However, as the season progressed, symptoms of common root rot were most severe on barley plants with the fewest tillers. In addition, the severity of the disease increased more rapidly on plants with the fewest tillers in wheat and barley. The major effect of the disease on yield reduction is that plants with more disease produce fewer tillers. A smaller effect is that grain yield per plant decreases as disease increases in plants with the same number of tillers, which indicates that common root rot decreases the yield of individual tillers.
