Peronosporaceae
Peronosporaceae is a family of water molds with around 600 species, which share some similarities with fungi. They’re mostly known as downy mildews since most species produce this disease. They are plant pathogens, with most preying on plants from the Magnoliids clade, and are considered parasites because they cannot survive without a host. Moreover, these molds possess specialized structures to penetrate the host’s tissues. Some of the most affected and targeted plants in agricultural practices are grapevines, tobacco, and lettuce. This often translates to high economic losses in crops and ornamental plants.
