Huang Qiuying's pest and disease control

Main diseases

The main disease that this plant is prone to is leaf spot, which is a relatively common disease. This disease mostly occurs in summer. As the temperature gradually rises, the disease will become more serious. At the beginning, purple-brown spots appear on the leaves, which gradually expand into circular spots. Eventually, holes will appear in the leaves.

The second is root rot, which is mainly caused by the fact that in winter, the moisture in the potting soil of chamomile does not dry up and the light oil cannot keep up. This disease starts to spread from the roots. If it is not treated in time, the entire plant will rot and die.

Disease control

If the first type of disease occurs, you can use a certain dose of carbendazim to treat it. If you want a better disease elimination effect, you can also choose to use streptomycin sulfate and thiophanate-methyl alternately. For the second condition, prevention is important, and try to reduce the amount of water during the winter. If you plant it outside and encounter continuous rainy days, you must ensure good drainage. Once this disease occurs during the growing season, it can be treated with a certain dose of root rot agent once a week for four weeks.

Main pests

Everyone may be familiar with aphids. Almost all flowers that are willing to be grown outside are prone to this kind of pests. This kind of insects will suck the juice from the stems and leaves, which can not only directly damage the yellow autumn jasmine, but the substances they secrete can also indirectly cause other diseases. They must be discovered as early as possible.

Pest Control

If this disease occurs, it is recommended to use a certain dose of Wanling or Dertensis to treat it. These two medicines can also prevent and control scale insects. Use once a week for up to 3 weeks to see improvement.
