Diseases and Pests of Artemisia strychnifolia and Their Control

Anthracnose damage

The cause of anthrax is Bacillus anthracis. In addition to plants, many animals can also be infected with Bacillus anthracis. For plants, the most susceptible seasons are spring and summer when the weather is relatively warm. At this time, not only is the temperature suitable, but the humidity is also moderate. Although the Sterculia sterculia will grow well, Bacillus anthracis will also multiply rampantly. In the early stages, only individual leaves will wither and fall off, but in the later stages, the withering will be more serious, and even the entire Sterculia sterculia will suffer irreversible damage. Therefore, if you encounter anthrax, you must treat it.

The harm of Artemisia serrata

Psyllids are relatively small and active, and are very harmful to plants. Compared with adults, larvae are less harmful, so prevention and control should be done as early as possible. Psyllids on the Sterculia tree will feed on the phloem of the plant and inject toxic substances, seriously affecting the growth of the plant.

Prevention and control methods of diseases and pests of Artemisia serrata

The prevention and control methods of anthracnose and psyllid disease are similar.

First of all, early prevention is relatively simple. In late winter, before spring comes, clear the diseased flowers, dead leaves and fruits inside the garden, and at the same time eliminate some insect eggs to prevent the large-scale reproduction of pathogens and the growth of insect eggs in spring. On the other hand, you can add fertilizer to the Sterculia to improve its own immunity. Finally, when anthracnose is more serious, it is necessary to spray drugs regularly, but it should be noted that the drugs sprayed for psyllid disease and anthracnose are different, and the proportions of the drugs are also different.

To add, the method of pest control is to attract some natural enemies. This method is environmentally friendly and simple, but it is only suitable when there are relatively few psyllids.
