pathogenic

path-uh-JEN-ik/ˌpæθəˈdʒenɪk/

Capable of causing disease

The scientist investigates the pathogenic organism responsible for the plant's disease.

A scientist in a laboratory examines a diseased plant beside a healthy control plant; a sealed culture dish and gloved careful handling emphasize an infectious cause, with no labels or inset.
Etymology

The pieces mean 'disease-producing,' making the connection causal: something pathogenic has the capacity to bring about disease.
