Morphology
The binomial combines 'Peronospora' (a genus of fungi) with 'destructor' (an agent that causes destruction), so a learner who knows both constituents can infer it is a harmful/destructive fungus affecting crops. This follows straightforward Latin naming logic and thus yields a general meaning of a destructive fungus, even if details like the specific host or symptom (downy mildew on onions) require domain knowledge.
Etymology
Peronospora destructor is a scientific name that tells a simple story: Peronospora is the group of downy mildews and destructor means 'destroyer'. The name creates the image of a grey, fluffy fungus covering onion leaves and 'destroying' crops, so it fits the disease that causes heavy onion loss.
