Main diseases

The main disease encountered by this plant is branch blight. Once it occurs, the most beautiful plant will change its shape. Seeing the name of the disease, Emei can know that the branches of the disease are gradually withering. Indeed, when the disease occurs, brown spots will appear on the twigs, and there will be black spots on them, and then wither gradually. However, how does this happen? It is mainly caused by bacterial infection, that is, the conidia of pathogenic bacteria, and then further invade the plant

Prevention and control measures

Before planting, we must select disease resistant varieties, so as to avoid the disease caused by their own lack of resistance. It can also allow disease resistant varieties to reproduce well

Even if the varieties are selected, they need careful maintenance in the process of planting. First of all, organic fertilizers should be added in time, which can improve their ability to resist bacteria. When there is too much rain, it should also be drained in time. If there is no timely drainage, the root is easy to rot, so the risk of disease will become greater

Once the disease is found, the branches that have been infected must be cut off in time, and the branches should not be discarded at will, so as to reduce the probability of their infection. It is best to burn the diseased branches and completely destroy this part of the diseased branches

When the disease has not spread, we must first carry out chemical protection. We can use scale mite spirit every half a month, which can eradicate the bacteria that have overwintered. In addition, after the disease has occurred, it can also be controlled with a certain dose of bactericidal reagent after disposing of the diseased branches
