What is the reason for the rotten vegetables? As the temperature drops and the humidity in the shed increases, vegetable vines will gradually enter a period of high incidence. There are many diseases that cause vine rot, mainly vine blight, gray mold, sclerotium, anthracnose and bacterial soft rot. Vegetable farmers must correctly identify the disease, prevent and treat diseases in order to be targeted. Vine blight Symptoms: Oval-shaped lesions appear on the stems of the diseased plants, some of them have milky white jelly, and the stems are severely cracked. Prevention and treatment: The disease can be treated with a combination of pharmaceutical prevention and environmental regulation. When the vine blight is 18℃~25℃ and the relative humidity is above 85%, the disease will be severe. Therefore, in the management of the shed, attention should be paid to heating and dehumidification. The shed temperature should be controlled at 25℃~33℃ during the day and 15℃ at night. ℃~20℃. For chemical control, 80% thiram 500 times or 75% chlorothalonil 500 times can be used for prevention, sprayed once every 7 to 10 days; after the disease occurs, 25% methamine can be sprayed 1000 times. anthrax Symptoms: The disease spots on the main vine and petiole are oval, yellowish-brown, and sunken. In severe cases, the spots are connected into pieces. Control: For plants that have not diseased, you can use protective agents such as chlorothalonil for control; after the disease occurs, you can spray with 25% bromoxonil 500 times or 25% methamine 1000 times mixed with 80% thiram 750 times. Bacterial soft rot Symptoms: In the initial stage, the stalk is water-soaked, brown and constricted, and the leaves are wilting from bottom to top. It is severe at noon and recovers sooner or later. When the stalk is cut open and squeezed by hand, milky white pus can be seen overflowing. Prevention and treatment: The disease is mostly caused by inadvertent wounds on plants during agricultural management such as vine falling and leaf picking. For the prevention and treatment of this disease, you can use 72% streptomycin sulfate 1500 times solution or 2% Zhongshengmycin 500 times solution for spraying. Sclerotinia Symptoms: Light brown water-soaked spots appear in the early stage of the infection of the stems, and the later diseased stems are soft and rot, and white cotton-like hyphae grow out. Control: On the basis of reducing the humidity in the shed, the chemical control can choose 50% vinyl sclerotium 500 times or 50 procymidone spray stalk, or use sclerotium clean smoke agent to smoke the shed.
