Botrytis cinerea mainly damages flowers and twigs. After the buds are infested, they begin to have water-stained irregular spots, and the lesions continuously expand, causing the whole bud to become soft and rot. After the diseased buds withered, they were hung on top of the diseased tissue. The pathogenic bacteria also invaded the tip of the flower that had been removed. In warm and humid conditions, the diseased part produced a large number of gray moldy layers. Control measures 1. Remove sick flowers in time, remove withered old flowers, and burn them together. 2. In greenhouse cultivation, pay attention to ventilation and avoid excessive humidity. 3. Onset of spraying 65% dexamethasone wettable powder 600 times, 75% chlorothalonil wettable powder 700 times or 70% thiophanate-methyl WP wet 1500 times.
