Through observation, I find that there are small red brown spots with clear boundaries on the leaves, forming nearly circular lesions, with a gray brown center and black brown edges. This anomaly may be caused by Black rot of grapes. Black rot of grapes mainly occurs on fruits, leaves, petioles, and new shoots. After the fruit is damaged, small purple brown spots appear in the early stage of disease, gradually expanding into brown edges, gray white in the center, slightly concave. The diseased fruit is soft and rotten, and then becomes dry and stiff, with obvious edges and not easy to fall off. Many black granular small protrusions grow on the diseased fruit. When the leaves are diseased, small reddish brown spots appear in the early stage, gradually expanding into nearly circular lesions with a diameter of 4 - 7 centimeters. The center is gray white, the outer edge is brown, and the edges are black brown. Many black small protrusions grow on top, arranged in a circular shape. The affected area of the new shoot has brown oval shaped lesions, with a central depression and black granular small protrusions on top.

By observing this image, I find a large number of oval shaped, clearly defined red brown small spots on the leaves, which are scattered on the leaves. The center is gray brown, and the edges are black brown. This phenomenon is caused by Black rot of grapes. Black rot of grapes mainly occurs on fruits, leaves, petioles, and new shoots. After the fruit is damaged, small purple brown spots appear in the early stage of disease, gradually expanding into brown edges, gray white in the center, slightly concave. The diseased fruit is soft and rotten, and then becomes dry and stiff, with obvious edges and not easy to fall off. Many black granular small protrusions grow on the diseased fruit. When the leaves are diseased, small reddish brown spots appear in the early stage, gradually expanding into nearly circular lesions with a diameter of 4 - 7 centimeters. The center is gray white, the outer edge is brown, and the edges are black brown. Many black small protrusions grow on top, arranged in a circular shape. The affected area of the new shoot has brown oval shaped lesions, with a central depression and black granular small protrusions on top.

Based on observation, I find that there are small red brown spots scattered on the leaves with clear boundaries, forming nearly circular lesions. The center is gray brown, the outer edge is brown, and the edges are black brown. This abnormal situation may be caused by Black rot of grapes. Black rot of grapes mainly occurs on fruits, leaves, petioles, and new shoots. After the fruit is damaged, small purple brown spots appear in the early stage of disease, gradually expanding into brown edges, gray white in the center, slightly concave. The diseased fruit is soft and rotten, and then becomes dry and stiff, with obvious edges and not easy to fall off. Many black granular small protrusions grow on the diseased fruit. When the leaves are diseased, small reddish brown spots appear in the early stage, gradually expanding into nearly circular lesions with a diameter of 4 - 7 centimeters. The center is gray white, the outer edge is brown, and the edges are black brown. Many black small protrusions grow on top, arranged in a circular shape. The affected area of the new shoot has brown oval shaped lesions, with a central depression and black granular small protrusions on top.

Through observation, I find that there are small red brown spots with clear boundaries on the leaves, forming nearly circular lesions, with a gray brown center and black brown edges. This anomaly may be caused by Black rot of grapes. Black rot of grapes mainly occurs on fruits, leaves, petioles, and new shoots. After the fruit is damaged, small purple brown spots appear in the early stage of disease, gradually expanding into brown edges, gray white in the center, slightly concave. The diseased fruit is soft and rotten, and then becomes dry and stiff, with obvious edges and not easy to fall off. Many black granular small protrusions grow on the diseased fruit. When the leaves are diseased, small reddish brown spots appear in the early stage, gradually expanding into nearly circular lesions with a diameter of 4 - 7 centimeters. The center is gray white, the outer edge is brown, and the edges are black brown. Many black small protrusions grow on top, arranged in a circular shape. The affected area of the new shoot has brown oval shaped lesions, with a central depression and black granular small protrusions on top.
