Disese induced by Albugo candida or Peronospora parasitica was found to have significant effects on the survival and reproductive output of affected individuals of Capsella bursa-pastoris. The time of infection by either pathogen was of considerable importance in determining the ultimate effect of disease. Systemic (primary) infection of seedling plants led to a high degree of mortality (88%) prior to reproductive maturity, however, localized or systemic secondary infection did not affect survival. Fruit production of surviving infected plants was negatively correlated with disease severity.
由白锈菌或寄生霜霉引起的疾病被发现对荠菜受影响个体的存活和繁殖产出有显著影响。两种病原体的感染时间在决定疾病的最终影响方面相当重要。幼苗植物的系统性（原发性）感染导致在生殖成熟前出现高度死亡率（88%），然而，局部性或系统性继发性感染并不影响存活。存活的受感染植物的果实产量与疾病严重程度呈负相关。
