Morphology

potato + mildew

The phrase is compositionally clear: 'mildew' names a fungal/whitish growth and 'potato' specifies the host, so a learner who knows both words can infer it refers to mildew affecting potato plants. Host+disease noun compounds are common and follow a regular English pattern, making the meaning immediately accessible to B1 learners.

Etymology

Potato mildew names what farmers saw: potato plants covered in a soft, white or grey fuzzy growth called mildew. Because that fuzzy growth is a disease that makes leaves and potatoes rot, the term now means 'a disease that damages potato plants'.
