In the process of planting cabbage, the most feared is that the cabbage is sick. If it is not treated in time, it will cause a large area of ​​production reduction. The cabbage planted by the villager Li Dagui had a problem. What happened? Let’s go and see the cabbage he planted. "The people in the village said that my cabbage was devastated. This disease is good or not, and my cabbage has not been saved. I hope that this a few acres of cabbage will be Chinese New Year this year." Li Dagui is a diligent person, and his land is also very strong. The growth of the corn is very good, but it rains continuously after the home is recovered. Many of them are moldy and cannot be sold. In order to have a good year this year, I planted a few acres of cabbage, I hope to buy a good price a year ago, an An An was born for a year. But who ever thought that cabbage had disease in the seedling stage, there were many spots in the heart leaf, and the seedlings also had the phenomenon of dead seedlings and deformities. The seedlings were not long after the disease, and the neighbors said that this was a convulsion, and Li Dagui was anxious. I don't know how to do it for a while. Here is a brief introduction to what is cabbage blast disease and its prevention and treatment measures. The cabbage disease is called viral disease. It occurs in cabbage and radish. After the virus disease, the cabbage can not be covered, and leaf malformation will occur. In the later leaves, there will be many necrotic brown lesions, which grow very slowly. If not treated in time, it will bring about a serious reduction in production. Most of the viral diseases are caused by aphids. In the case of heavy crops and adjacent crops, the occurrence of the disease is more serious. The seedlings of cabbage before 6-7 leaves are susceptible to infection. After the onset, amino oligosaccharide + allicin + pyridoxone + silicone can be used to prevent and control diseases while paying attention to the control of aphids. In order to better exert the efficacy, silicone additives can be added. The most important disease is prevention. It can be applied once by the biological bacteria after the seedlings are fixed. It also plays a certain regulatory role in preventing disease. Once the disease occurs, it has already caused a certain degree of reduction in production.
