This kind of flower is white in color and small in size. Compared with the leaves, the size contrast is very obvious, so it can be seen that it is very lovely. So if such a lovely flower encounters diseases and insect pests, how to deal with it? Take a look!

Sheath rust

The leaves suffering from this disease usually have raised packets on the upper and lower surfaces, which are yellow, orange or rust colored, or even black spores. Although this disease will not cause fatal damage to the plant and the leaves will not die, it will certainly affect the growth of the plant. Therefore, once the leaves of this plant are found to be infected, the leaves should be cut off immediately, and then controlled with professional chemicals

White silk disease

When you see the name of this disease, you will probably think of its disease. It is really like silk. The filamentous material wrapped around the leaves often appears when the rainfall is relatively large. In serious cases, it will also lead to root rot. Once the disease is found, scrape off the soil with bacteria on the upper layer, and sprinkle with disease prevention powder such as lime. If you want to cure it, you must pay attention to the surrounding light and temperature. If the disease is serious, the whole tree will be burned

Anthrax

This disease can occur many times of the year, but the most serious time is when the temperature and water volume are relatively high. At first, the disease spot is at the leaf tip, and then it will slowly extend to the rhizome. At first, it is brown, and then it will slowly become more. In severe cases, it will also lead to the death of the whole plant. During the onset of the disease, special agents can be sprayed directly. Once every seven days or so, a total of 3-5 times

Scale insects

Scale insects are the most easily infected insects. We are quite familiar with this kind of insects. Similarly, they reproduce faster when the temperature and humidity rise. They can be sprayed with medicine at the beginning of hatching or scraped off manually, but this method is more suitable for friends with less pots
