Downy mildew (peronospora) is caused by which organism?

Explanation:
Downy mildew on grapevines is caused by an oomycete, a water mold. These organisms are not true fungi or bacteria and they behave differently from viruses. They live in the leaf tissue and produce spores on the underside of leaves when moisture is present, with spores that spread in water. This tissue-dwelling, water-spore lifestyle is what makes a water mold the best description for the organism behind grape downy mildew.
