Control methods: after the discovery of sugarcane moth, quick-killing agents such as chrysanthemum EC can be used to irrigate the injured parts of the stem, and trichlorfon is used to make poisonous soil and sprinkle it in the topsoil of flowerpots. In addition, when choosing and purchasing plants, we should carefully observe and select healthy plants that are disease-free and put an end to them from the source.

2. For grain wood bark beetle

A pest that harms Brazilian wood, which mostly occurs in the growing period and is very harmful.

A disease that harms the stems of Brazilian wood, which is generally spread by water sputtering and is prone to disease after a long time of moisture retention. Symptoms: the stem or base of the Brazilian wood rotts, causing the whole plant to die quickly.

In addition, fertilizing once every 20 to 30 days in the peak growing season of Brazilian wood can effectively reduce the occurrence of this disease.

5. Epidemic disease

It mainly harms the leaves and ground of Brazilian wood. Symptoms: at the initial stage, the diseased leaves appear water-immersed spots, and then quickly expand into black-brown rot, resulting in fallen leaves, and sometimes there is a white thin mildew layer on the damaged surface of the leaves.

Prevention and treatment: cut off the diseased leaves in time and burn them or bury them in soil in order to reduce the source of the disease. When the disease occurs, it can be sprayed with 72.2% Pulicol water agent 600-700 times for prevention and treatment. If it is raised outdoors, it is necessary to take measures to protect it from the rain and prevent it from getting too wet, which are all factors that cause the disease.
