Tomato gray mold occurs mainly in protected cultivation, and leaves, flowers, and fruits are all affected. The incidence of leaf blade was more inward than the tip of the leaf. The lesion was light-colored to yellow-brown. The diseased part of the disease was dry and brown-brown mildew. When the flower was onset, it caused burnout; , First from the residual rancidity and stigma first dip dyeing, and then to the fruit development, resulting in soft rot of young fruit, mature lesions on the green fruit stains, gray, gray fruit on the surface after the dense moldy material. In the winter and spring of this year, due to prolonged periods of low-temperature and low-temperature sunshine, the rain and snow weather affected the continuous low temperature and humidity in the shed, which was extremely unfavorable to the growth of tomato, resulting in the serious occurrence of tomato gray mold in the protected area. According to the survey, the incidence of Botrytis cinerea is 40%-80%, and the incidence of leaf is 15%-30%.
