Order: Peronosporales (Downy mildews)
This group contains the most advanced Oomycota. They are
mostly obligate parasites on the aerial parts of higher plants. This order
contains many destructive parasites of economic plants, and causes tremendous
losses in crops each year. Since their spores are wind borne, their sporangia
are not unspecialized hyphal tips, but borne on branched aerial asexual
"sporangiophores", which produce asexual spores,There are also sexual
sporangia borne on"sporangiaophores".
