Symptoms of brown rot of cherry radish and white radish:

This disease can occur throughout the growth period, and all parts can be affected.

In the seedling stage, the disease mostly affects the roots and stems, initially forming small water-soaked necrotic spots. Later, the diseased areas shrink and become grayish white to grayish brown. The leaves of the vegetable seedlings wilt and die from bottom to top.

Infection in the middle stage of growth usually starts from the lower leaf margin or petiole. Small water-soaked necrotic spots are initially formed, light green, and gradually develop into semi-circular or nearly circular necrotic spots, gray-brown to gray-brown. Dark brown with lighter edge color. As the disease progresses, the diseased part gradually rots, eventually causing all leaves and petioles to rot, and gray-brown to yellow-brown filaments appear on the surface of the diseased tissue.

The rhizome is damaged in the late growth period, and small water-soaked yellow-brown spots initially form, which quickly expand into irregular necrotic spots, with yellow-brown edges and dark brown centers. The diseased tissues rapidly fester and crack as the disease develops. Or after necrosis and rot, it separates from the healthy tissue and forms a cavity. In severe cases, the rhizome rots in pieces.
