Morphology

Phytophthora + infestans

This is a scientific Latin binomial rather than a regular English phrase; its meaning (a specific plant pathogen causing late blight) is not compositionally derived in ordinary English from its parts. The genus name is a technical term and 'infestans' is a Latin participle not listed in the learner dictionary, so an average B1 learner who knows the listed constituents would not be able to infer the disease-causing species sense.

Etymology

Phytophthora infestans comes from old Greek and Latin parts: phyto means 'plant', phthora means 'destroy', and infestans means 'attacking'. So the name shows a tiny living thing that attacks and destroys plants, which explains why it causes serious disease in potatoes and tomatoes.
