Last Updated: 2024/11/06, This is not a very common phenomenon, but it can also happen. There are three main reasons. The first disease is powdery mildew. In view of this, we first need to get rid of the infected part, and then spray some carbendazim and so on. The second situation is insect pests, such as "blowing cotton scale" and so on. The treatment is similar to the first one, treat the diseased leaves, and then spray. The third is caused by exposure, which is relatively rare, but it is also a possible reason. Should be properly shaded and ventilated.

1. Disease problem

(1) specific reason: "powdery mildew" is one of the great threats to this plant. This is a fungal disease. When you get sick, there are some small spots at first. Then, slowly, it will develop into a white mildew layer and appear powdery. It looks as if the leaves have turned white. Generally speaking, the incidence of disease in the lower part of the leaf is higher than that in the upper part, and there will be more in the back than in the front. If so, then probably contracted the disease.

(2) solution: first of all, cut off the leaves that have been infected and deal with them. After that, clean up the surrounding environment and disinfect it best. Then, you can spray some medicine to treat the disease, such as carbendazim and so on. The main thing to pay attention to in the future maintenance is moisture, not too much, and it is best to pour it from the edge of the basin. In addition, ventilation is also important.

2. Pest problems

(1) specific reason: there is a kind of insect called "blowing cotton scale". It is white, and if it gives birth to this bug, its leaves will look white.

(2) solution: similar to the treatment of the disease, get rid of the diseased leaves. Then spray, such as omethoate, etc. In addition, biological methods can also be used, such as introducing some ladybugs and so on.

3. Caused by exposure

(1) specific reason: sometimes, after a long time in the sun, some leaves are sunburned. In that case, it is also possible for the leaves to turn white.

(2) solution: it is best to put it in a place with astigmatism and do not expose it to the sun. At the same time, pay attention to ventilation.
