1、 Disease

There are not many kinds of diseases of this plant. There is only one main disease, called "anthrax", so let's introduce this disease in detail

This disease mainly damages its leaves. When it occurs, many gray brown round spots will appear on its leaves. If the black spots continue to develop, they may appear. The bacteria will spend the winter in the soil or on sick leaves, spread by air flow or watering, and then re infect through spores. There are two to three peak periods of disease in the south every year, while there is only one in the north. The degree of the disease depends on the amount of precipitation. If it rains continuously, it may increase the probability of the disease

To prevent and control this disease, we must first deal with the diseased leaves that have been infringed, cut them off and deal with them in several ways to reduce the source of infection. In addition, some drugs are used, such as 25% of tanteling powder and 500 times of liquid medicine. They are carried out every ten days or so, about three or four times. In addition, the management in the later stage is also more important. For example, the light should not be too strong, otherwise it will also cause it to get sick, because this plant belongs to shade tolerance

2、 Pest

There are many pests threatening this plant, such as grubs and so on. They mainly exist underground and breed faster, so they do great harm. They all bite the roots of the plant that exist underground. After reaching a certain degree, the plant will fall down and die. To deal with these pests, we can spray lesbon 1000 times, or use the extract of plant ash
