Tomato gray mold mainly occurs during the flowering and fruiting periods, and can harm flowers, fruits, leaves and stems. During the seedling stage, water-soaked rot occurs on the leaves and petioles, and then dry up and gray mold occurs on the surface. In severe cases, it can expand to the young stems, causing gray-black lesions to produce gray-black spots and rot and break. On the leaves, water-like light brown lesions begin to appear on the tips of the leaves. The lesions are in the shape of a \”V\” and develop inwardly. When wet, the diseased part will grow gray mold, with irregular edges, and when dry, the lesions are grayish white. Small water-soaked spots occur in the initial stage of the stem, and then expand to grow stripe lesions. When it is high in humidity, gray mold will grow, and the upper plant will die. The fruits are mainly in the green fruit period. They first infect the remaining stigma or petals, and then develop to the fruit surface and stems. The peel turns gray-white, water-soaked, soft rot, and the diseased part grows a gray-green villous mold layer. In the later stage, the diseased part produces black-brown rat fecal-like sclerosis. The calyx turns dark brown and then dry.这种疾病主要影响西红柿的果实，导致果皮显得灰白色，柔软而腐烂，而小腿也会出现灰褐色的霉菌层，果实将变得深水和刚性。 The leaves die directly.
