Disease Introduction MechanismPeronospora parasitica is an exclusively biotrophic oomycete responsible for crucifer downy mildew, one of the most important diseases of brassica crops worldwide. Brassicas are economically very important all over the world, Brassica oleracea being the most cultivated species in the Western Hemisphere, whereas B. campestris predomin- ates Asia. Between 1989 and 1991, world brassica crops represented 16 69 000 ha, increasing to 19 83 000 ha in 1999 (FAO 1999). Although field plants are also severely affected, crucifer downy mildew damages are particularly important in the nursery, when the infection may kill the seedlings, retard their development or cause lack of uniformity and quality.
