Prevention

1. Cultivation management measures. 1 New planting banana plant must choose tube seedlings that are free of disease or pure soil cultivation. It is strictly forbidden to introduce seedlings from the ward. 2 It is necessary to strengthen the leakage prevention between the banana gardens and implement independent irrigation and drainage. 3 The lime in the pre-planting point regulates the pH of the soil; at the same time, the application of the new high-fat membrane can repel the underground pests, isolate the virus infection, prevent the roots and reduce the chance of infection. 4 pay attention to the application of nitrogen, phosphorus and potassium and increase the application of calcium and magnesium fertilizer + strong fruit Tilling to enhance the disease resistance and disease resistance of banana plants.

2. Block the ward to prevent the spread of the disease. If a sporadic disease plant is found in the banana garden, it should be immediately uprooted and the diseased plant broken up, put into a plastic bag, add lime and seal the bag mouth, remove it and keep it away from the banana plant to make it rot. 1 The soil is disinfected on the diseased hole; after the diseased plant is removed, the diseased point sprays the tree to kill the germ. 2 Independent irrigation and drainage is carried out in the ward, and it is strictly forbidden to bring bacteria into the disease-free banana garden. 3 Tools for cultivating in the ward must be immersed in 50% formalin solution for disinfection before use in disease-free banana plantation. 4 The banana orchard with more than 30% of the disease should be replanted with rice or aquatic crops, and then planted with bananas after two years of flooding. The mountain banana plant can be rotated with sugar cane and peanuts.
