Cucumber downy mildew occurs at the seedling stage, and irregular chlorotic yellow-brown spots appear on the front of the cotyledon, and the diameter of the spot is 0.2-0.5 cm. When it is wet, gray-brown moldy matter is produced on the back of the spot, and the cotyledon turns yellow when it is severe dry.
