How to prevent mulberry leaf mosaic?

Mulberry mosaic is one of many diseases. When mosaic occurs, the color and layering of leaves are obviously different, including different types such as mosaic, annular leaves and reticular leaves, and the symptoms of different types are also different. Which one belongs to needs to be observed slowly from the early stage to the later stage. Let me talk about prevention and control methods.

Careful selection of different mulberry varieties has great differences in some of their own characteristics. Choosing varieties with strong disease resistance has lower incidence and lower probability of mosaic disease. According to my experience, I think we can choose Zhuangsang, such as Zhuangsang No.2, which has high harvest coefficient, leaves will not wither so quickly, even a little illness can be saved in the later stage, and it has strong ability to resist epidemic disease and yellow dwarf disease, and mosaic disease is not a big threat to it.

Mulberry orchard management and protection is the management and protection of mulberry in various periods, such as regular inspection, fertilization and mulberry cutting. These are the important contents of management and protection. Summer felling is the focus of management and protection. I think it should be done as early as possible during the summer felling. In this way, the mulberry seedlings that grow later will have enough time to absorb nutrients and grow better. However, after cutting in summer, don't pick too much and raise it reasonably, which will reduce the occurrence of mosaic phenomenon. Mulberry orchard management also needs to regularly check the condition of mulberry leaves, such as color and size. Pay attention to the rational use of various fertilizers to ensure the growth of mulberry trees, dig out diseased plants in time and remove germs.

Quarantine work is indispensable. At present, the quarantine work of mulberry is mainly domestic quarantine, and corresponding measures should be taken according to the pest situation in a certain area. Mulberry trees need strict management, and seedlings and scions in some epidemic areas must not be transported to non-epidemic areas, otherwise the disease will be more serious. Nursery inspection is the focus of quarantine work, and diseased plants can be completely removed by inspection before leaving the nursery. In the scion, it is necessary to check the previously marked diseased plants, and the marked diseased plants shall not be grafted.
