Morphology
The compound is compositional: 'blister' specifies the type of 'rust' (a fungal disease), so a learner who knows 'blister' (raised bubble) and 'rust' (a plant fungal disease) can infer it refers to a rust disease that produces blisters on bark. This noun+noun formation follows a transparent descriptive pattern common across languages and is therefore readily deducible by B1 learners.
Etymology
Blister rust is named for how the disease looks: the fungus makes raised, blister-like swellings on the bark, and 'rust' is a common name for plant diseases that leave rusty spots. So, blister rust means 'a fungal disease of pine trees that causes blisters and open sores on the bark'.
