病菌群体内部的变化,常使得利用杀菌剂和抗病寄主防治病害的问题复杂化。这些内部变化趋使病菌群体的适应性恢复到药剂使用前或抗病基因引进寄主前就存在的平均水平,结果是防治措施的明显失败。已经提出了几种策略用以阻止或延缓结果能导致所采用的病害防治措施失败的病菌群体内部的变化。这些策略包括采用耐久抗病基因和抗病性基因管理系统延长寄主抗病性;
Changes within the germ population often complicate the use of fungicides and disease-resistant hosts to combat the disease. These internal changes tend to restore the resilience of the germ population to the average levels that existed prior to the introduction of the agent or prior to the introduction of the disease-resistance gene, resulting in a significant failure of the control measures. Several strategies have been proposed to prevent or delay changes within the population of bacteria that result in the failure of the adopted disease control measures. These strategies include the use of durable disease resistance genes and disease resistance gene management system to extend host resistance;
