Downy Mildew

How to Grow Plumeria > Downy Mildew

Known best by its common name, downy mildew is caused by the oomycete. It is an obligate parasite of vascular plants, meaning that it cannot survive outside of a living host. It does not produce overwintering oospores, but survives from year to year on living plants. These organisms are distinctly different from the powdery mildews.
