The disease is harmful to flowers, fruits, stems, leaves and other organs, the bacteria first invade from the withered female flowers, the petals in the initial stage of infection are water-soaked or water-stained, and then become soft rot and appear brown-brown mold layer, causing the petals to rot Wilting, falling off. Then, the germs gradually developed into young fruit. The affected parts first became soft and rot, and a large number of gray mold layers were born. If the diseased tissue falls on the leaves or stalks, it can also lead to the onset of stems and leaves. Irregular large spots are formed on the leaves. There are brown ring patterns in the center, and gray mold layer is seen when the humidity is high. Stems become infected and gray lesions appear. After one week of stems, stems can be broken. How to prevent the disease?
Clean the pastoral and shed film to timely remove diseased tissues such as diseased leaves, diseased flowers, and diseased fruits, and promptly bring out the shed or destroy it. Clean the greenhouse membrane, increase the transparency, to increase the growth of the plant, thereby enhancing its resistance to disease.
Adjust the temperature and humidity of the greenhouse to promote the cultivation method of sorghum film or drip irrigation, timely watering, as far as possible to maintain a high temperature in the morning, this can inhibit the sporulation of pathogens, and make the dew in the shed can be evaporated. Increase the amount of ventilation in the afternoon to reduce the humidity inside the greenhouse. At night, the temperature of the greenhouse should be appropriately increased to reduce or avoid condensation on the foliage.
To prevent bacteria from invading the wound during the use of 2,4-D flower, because it is easy to cause wounds and conducive to the invasion of bacteria, so in the flowering time can be added in 2,4-D carbendazim and other fungicides to control the bacteria Intrusion. In addition, in the course of agricultural operations, it should be avoided as far as possible to cause wounds and reduce the spread of diseases.
Pay attention to the application of pesticides in the process of chemical control, should minimize the spray, so as not to increase the humidity within the greenhouse, you can choose to use aerosol or dust and other methods, and alternate rotation of various agents to reduce the resistance of the disease.
In recent years, the occurrence and harm of gray mold of courgettes grown in greenhouses has been very serious. According to the survey, it can cause a reduction in production and even cause a shed.
