The latest pest control of Dendrobium candidum

1. Snail

The bug is mainly hidden on the back of the leaves, basically by eating the leaves or biting its stems to hurt the petals. The biggest headache is that it will happen many times in a year, once it happens, the harm is very great, basically one night can eat up the whole plant, so we must carry out timely prevention and control.

Prevention and treatment: we can find some bait, mix it with a little poison, put it where they often appear, and we can successfully get rid of them. Or you can spray some pesticides on the cultivated soil or the surrounding environment, or you can use some quicklime and salt water to prevent and cure it. In addition, in peacetime, it is best to pay attention to the hygiene of the cultivation place, such as those that have withered leaves must be cleaned up in time.

two。 Dendrolimus angustifolia

This kind of insect is usually parasitic on the edge of its plant leaves or on the back of its leaves, mainly to absorb the sap of the plant to survive, so that the leaves of the whole plant will begin to kill, and in serious cases, it will directly kill the plant. At the same time, it may also cause some other diseases.

Control methods: this pest is usually in May when it is the peak of its development, we can mix a little pesticide spraying at this time, so the effect will be better. If it is a formed bug, and the quantity is small, you can cut off its old branches and leaves, and then burn them together.

3. Black spot disease

When the disease first occurs, there will be a lot of dark brown spots on the leaves. As they develop slowly, they will gradually appear yellow near the spots on the leaves. In severe cases, the black spots will form pieces with each other and eventually fall off.

Prevention and treatment: this disease usually occurs at the beginning of summer, so we need to choose some pesticides to spray at this time, so that we can quickly control its follow-up development and prevent it from pathological changes.
