Similarly, cucurbit downy mildew (caused by Pseudoperonospora cubensis) is specific to cucurbits (e.g., cantaloupe (Cucumis melo), cucumber (Cucumis sativus), pumpkin, squash, watermelon (Citrullus lanatus) and other members of the Cucurbitaceae/gourd family).
Traditionally the Edakkad area was famous for its local variety / landrace of watermelon (Citrullus lanatus, Family Cucurbitaceae) referred to as Edakkad Bathakka.
