In recent years, many growers have responded to bacterial glids in cucumbers, and the damage is very serious. This widespread disease has become a major disease in wintering cucumber cultivation. The disease is highly contagious and harmful. Strong, has a great impact on the yield and quality of cucumbers and benefits, but because farmers do not have enough knowledge of the disease, often miss the best prevention period. Let's take a look at the bacterial bacterial gum disease in cucumber. First look at the bacterial glia in different parts 1, the stalk at the pus The disease is mainly caused by Pseudomonas syringae, which is transmitted or expanded through the wound or the tissue of the plant, infects the petioles, hanging strips, leaves and seedlings, and flows out of the white colloidal pus. Especially in greenhouses with high humidity, the speed of transmission is extremely fast, and serious plants can cause large areas to die. 2, the fruit on the pus Cut the diseased fruit, the internal flesh becomes brown and rot, and the melon is soft and rot-like. 3, cut the disease fruit Humidity and temperature are the main environmental conditions for the disease, and the humidity is high and the incidence is heavy. The temperature in the shed is 20-28 °C, which is suitable for bacterial infection. The longer the low temperature in the shed in autumn and winter, the greater the humidity and the more serious the disease. Pathogenic bacteria can invade from the wound, so the planting, threshing, snoring and other agricultural operations will cause pathogen infection and accelerate the development of the disease. 4, petiole at the petiole Similar to the bacterial pus at the stem, it is also a bacterial gum disease caused by Pseudomonas syringae. Comprehensive preventive measures: 1. You can choose a cucumber variety that has resistance to pests and diseases. When planting cucumber varieties, we can choose high-resistance and multi-resistant cucumber varieties, which is an economical and effective measure to control pests and diseases. 2. Agronomic measures such as reducing humidity, enhancing ventilation and light transmission. In the case of continuous cloudy days, we can lay rice husks in corridors and planting rows, reducing humidity and increasing the amount of carbon dioxide in the air, which is also helpful for increasing production. 3. Remove the old leaves, yellow leaves, diseased leaves, etc. of the diseased plants in time, and prevent the plants from appearing wounds, so it is very easy to cause bacterial infections. Clean the garden, keep the greenhouse clean, clean the diseased plants in time, and take them out of the shed for centralized treatment. 4, chemical control, can be used leaf azole, thiazole zinc, copper hydroxide, zhongshengmycin, chlorobromoisocyanuric acid, Chunlei · Wang copper and other agents. The above is about the introduction of bacterial gum disease. The scary thing about this disease is that it does not only appear in one part, but also appears in all parts of cucumber. It is extremely harmful, so growers must pay attention to it. It is.
