Prevention methods for bacterial diseases such as bacterial soft rot

Once a plant disease is contracted, it is there to stay; the lesions will remain forever and cannot be cured the way human illnesses can, so the key to any plant disease lies in prevention. Preventing fungal diseases is relatively difficult, but bacterial diseases can be prevented. Bacterial diseases are generally brought onto the plants by bacteria from seedlings, soil, pots, tools and human contact, and then enter through wounds to cause infection. Therefore, prevention requires the following: 1. It is best not to bring in diseased seedlings. Seedlings that are brought in should be disinfected, preferably by soaking in potassium permanganate solution. 2. Disinfect the soil, preferably by steaming. 3. Disinfect pots and tools; they can be soaked in potassium permanganate solution, or steamed and heated at high temperature. 4. Protectorchidwounds; smearing the wounds with plant ash (wood ash) is the best and most convenient method. 5. Reduce contact with outsiders. 6. Diseased plants should be isolated, and dead and leftover leaves should be taken out of the orchid growing area. 7. Drug prevention. Author: Liu Jingqiu
