Disease and Pest Control of Dendrobium officinale

1. Snail

This kind of insect mainly hides secretly on the back of the leaves, and basically damages the petals by eating the leaves or biting the stems. The most troublesome thing is that it occurs many times a year. Once it occurs, the damage is extremely serious. Basically, the entire plant can be eaten up in one night, so timely prevention and control must be carried out.

Prevention and control methods: We can find some baits, mix a little poison in them, and put them in places where they often appear, and we can successfully get rid of them. Alternatively, you can spray some pesticides on the cultivated soil or the surrounding environment, or you can use some quicklime and salt water for good prevention and control. In addition, it is best to pay attention to the hygiene of the cultivation area at ordinary times, and those withered leaves must be cleaned up in time.

2. Philippine shield scale

This kind of insect usually parasitizes on the edge of the leaves of the plant or on the back of the leaves. It mainly sucks the juice of the plant to survive. This will cause the leaves of the entire plant to begin to dry up, and in severe cases it will directly kill the plant. It may also cause some other diseases.

Prevention and control methods: This pest generally reaches its peak development period in May. We can mix it with a little pesticide and spray it at this time, which will have a better effect. If the insects have already formed and there are not many of them, you can cut off the old branches and leaves, and then burn them together.

3. Black spot

When this disease first occurs, many dark brown spots will appear on the leaves. As the disease develops slowly, you will find that yellow will gradually appear around the spots on the leaves. In severe cases, the black spots will form plates and eventually fall off.

Prevention and control methods: This disease usually occurs at the beginning of summer, so we need to choose some pesticides to spray for prevention and control at this time, so that we can quickly control its subsequent development and prevent it from becoming diseased.
