Winter is coming. Succulent plants with white bugs? How to get rid of it?

Winter is coming, and succulent plants have "white" bugs? Dense, how to get rid of it? This kind of insect is a scale insect. It is the most common pest of succulent plants. It is often clustered on the stems and leaves of plants, sucking sap from the stems and leaves, causing the stems and leaves of the plants to wither, and some even kill the whole plant. In addition, it will also induce soot disease, which is relatively harmful to plants. I believe that friends who raise too much succulent plants have encountered it, reproduce relatively fast, look particularly annoying, and flower friends with dense phobias may not be able to stand it. next, we briefly introduce the scale beetle and its control methods.

Where do scale insects generally appear on succulent plants?

In the succulent branches and leaves and root soil, there are high incidence areas of scale insects, and the eggs are very small, so it is difficult for us to observe with the naked eye that from eggs hatching to adults, the fast ones take two or three months, and the slow ones take three or four months. The long time span may give you an illusion that I didn't have scale insects at that time, but now I suddenly have them. Scale insects basically crawl, while aphids can fly.

Why do succulent plants have scale insects?

Most of the succulent plants you buy are branches and leaves, roots, soil scale insects, or eggs, but you don't see them until they explode to a large scale. The greenhouse itself is a high-outbreak area of scale insects, but it has been suppressed by various means, and it is entirely possible for roots, soil, and even succulent plants to leave some insects and eggs occasionally.

Related to the maintenance of environmental humidity

Too high humidity is often conducive to the occurrence of scale insects, rarely cause nymph death, but the survival rate of scale insects decreases under low humidity conditions. When the average relative humidity was less than 38%, the hatching rate of eggs decreased by 89.3%. When the humidity is less than 15%, a large number of nymphs will die, so dry years are not conducive to the occurrence of scale insects. Therefore, succulent plant pests are mostly caused by the growth environment is not ventilated, muggy, humid, therefore, the usual environmental ventilation is very important.

Succulent plants have "white" bugs? Dense, how to get rid of it?

A more environmentally friendly and quick way is to wipe the diseased leaves repeatedly with alcohol, which can completely remove scale insects, and even the larvae invisible to the naked eye can be killed. The method is safe, simple and effective. It is also possible to use rice vinegar. Gently wipe the leaves with diseases and insect pests with cotton ball dipped in rice vinegar, which can not only have a thorough insecticidal effect, but also make the plant leaves green and shiny. For example, when wiping the diseased leaves of orchids with alcohol, not only the scale insects can be removed, but also the larvae that are not visible to the naked eye can be completely killed, and the harm of scale insects is rarely found in the second year. This method is simple, safe and effective.

The domestic liquor mixed with water can also be used to control scale insects on succulent plants. According to the proportion of 1:2, the surface layer of the basin soil can be watered once in the middle of April, and then every half a month or so, the effect is the best for 4 times in a row. It is found that scale insects are difficult to clean up at once, the reproduction of scale insects themselves is large, there are few special drugs to control scale insects, and the eggs may remain in the soil, but there is no need to be too depressed. Generally speaking, a small amount of residual scale insects do not have a serious effect on succulent plants.
