1、 With what medicine

This kind of plant starts to suffer from this disease, and many round or non-circular small spots will grow on the leaves. The leaves of more severe plants will fall and the branches will slowly dry up, so it is necessary to treat them as soon as possible. At this time, the sick leaves of the plant can be cut off, and then the plant can be sprayed with bactericidal drugs several times, and put it in a place with good air circulation. Also reduce the amount of water given to the plant, and there is no need to spray water on the leaves of the plant

2、 Prevention and control methods

1. Placement: the main reason for this kind of plant suffering from this disease is that the temperature in the place where it grows is a little high, and the amount of water molecules in the air is relatively large, so it should be placed in a place with good air circulation, and pay attention not to be too high in the breeding environment

2. Soil: select the soil with good drainage before planting the plant, so as to avoid the plant suffering from this disease due to too much water in the soil. In ordinary management, we should also be careful and pay more attention to the drainage problems in the field to avoid making the plant sick due to poor drainage, which will also strengthen the ability of the plant to resist diseases

3. Pruning: after the plant is found to be sick, except for cutting off the sick leaves at that time, after entering the winter, cut off all the sick branches and leaves, and then put them together for destruction
