Cucurbit downy mildew, caused by the oomycete Pseudoperonospora cubensis, is a yearly concern for North Carolina cucurbit growers. The disease affects cucurbit crops such as cucumber, watermelon, cantaloupe, pumpkin, and squash, but cucumber is particularly susceptible. The Cucurbit Downy Mildew IPM pipe website has been established to provide an early alert system to cucurbit growers so they can initiate preventive sprays once the disease is found in neighboring states, and they can switch to more aggressive spray programs once the disease is in North Carolina to avoid any crop loss and unnecessary sprays.
