Will succulents have pests and diseases? What should I do if there are pests and diseases?

After entering the spring, various pests and diseases that accompany the succulent occur one after another, but the prevention of succulent pests and diseases should be carried out in the way of "prevention first, prevention combined". First of all, it is necessary to have a good planting environment such as proper temperature, humidity, good ventilation and light transmission conditions, and then spray regularly to prevent it. Preventive measures should be taken in time when pests and diseases are found.

In addition, succulents are mainly maintained indoors, so it is easier to prevent pests and diseases. The room is well ventilated and the temperature is moderate. Common pests and diseases in succulents and how to control them are as follows.

Red spiders mainly harm succulents of the Lovaceae, Dafan family, Asteraceae and lily families, and most of the larvae of red spiders eat the sap of the young stems and leaves of plants, and the infested stems and leaves sometimes lose yellow-brown spots or yellow, which cannot fade. If such a loss occurs, in addition to measures to strengthen ventilation and reduce temperature, dicofol solutions can be used to gently kill insecticides.

Golden hornworm has great harm to plants with tightly arranged leaves, such as agave, 12 rolls and other plants mainly absorb the stem and leaf juice of plants, resulting in poor growth of plants and death in severe cases. In the event of an insect infestation, in addition to using a brush to drive away, you can also use a vegetarian smashing solution.

Aphids mainly damage succulents in the Sedum and Asteraceae families, and too many mites in plants can lead to weak plant growth, and aphid secretions can induce ant invasion. Medicated prophylaxis when mites are first spotted**, can be sprayed with 80% infrared oil.

Red disease is a bacterial disease, which is the main disease of succulents, mainly harming succulents with stem streams, the disease invades from the root wound, and reddish-brown lesions appear on the stems after the onset of the disease, and rot and die after a few days. Therefore, succulents can be prevented before planting with a humidifying powder with unfirm soil. If the tuber is found to have a wound, it should be dried, disinfected and planted.

It is not only a fungal disease, but also an important disease that harms succulents, which mostly occurs in the rainy season of high temperature and humidity, after the plant is sick, there will be light brown water stains on the stem, and gradually begin to rot. At this time, it is necessary to open the window, ventilate, reduce the humidity and temperature of the indoor air, and then spray methylthiobacterium moisture-proof powder to prevent the spread of the disease.

Rust mostly occurs in succulents with generous succulents, and at the onset of the disease, large greenish-brown spots appear on the stem epidermis of the plant, which expands upwards from the base of the stem, and in severe cases, the stem is covered with spots. After the onset of the disease, combined with pruning, cut off the diseased branches, and the new branches germinate again, you can spray plastic alcohol humidifying powder.

The most feared thing about preserving succulents is the pests and diseases encountered, but there is no need to be afraid to meet them. The vitality of most succulents is still tenacious. Even if it survives there, it's just a little bad.

Therefore, succulents can produce pests and diseases, as long as they are targeted, there is no problem.

There will be pests and diseases, first of all, you need to replace the soil, and at the same time put the succulent in the sun to dry, and you need to buy insect repellent and put it in the new soil to prevent insect eggs from hanging in the succulent.

Succulents can also have pests and diseases, such as rust, root powder, etc. It should be prevented and controlled with pesticides in a timely manner, and there are many special insecticides for meat on the Internet, and the leaves can also be wiped with vinegar and alcohol to remove insects.

There are many pests that harm succulents, such as red spiders, scale insects, and gray butterflies. Red spiders can be sprayed with dicofol, scale insects should be prevented with carbofuran, and gray butterflies are generally eliminated with scales. Its main disease is black rot, which requires a knife to remove the diseased area, after which it is sprayed with benzolite and covered with sulfur powder to prevent wound infection.

Succulents in summer tend to produce small white worms called scale worms, which survive by sucking the sap of the plant, causing wilting and fungal infections. Because the body has a layer of keratin carapace, general insecticides have limited effect. When the quantity is small, it can be caught manually, and if there are many cases, it can be used to kill drugs.

But out of concern for the environment and health, Dream Garden does not encourage the use of chemical pesticides. This is a very small pest, the whitefly, which not only sucks the water of the leaves, but also secretes honeydew that brings all kinds of mold. The infested leaves are often accompanied by black mold, which can lead to severe problems.

Scale insects. Succulents in summer tend to produce small white worms called scale worms, which survive by sucking the sap of the plant, causing wilting and fungal infections. Because the body has a layer of keratin carapace, general insecticides have limited effect.

When the quantity is small, it can be captured manually, and if it is large, it can be used to kill drugs. However, due to environmental and health concerns, Dream Garden does not encourage people to use chemical pesticides.

Whiteflies. This is a very small pest, the whitefly, which not only sucks the water of the leaves, but also secretes honeydew that brings all kinds of mold. Infested leaves are often accompanied by black mold, which can lead to the death of the whole plant in severe cases.

Early detection and rapid isolation can avoid the transmission of other plants. If you must use insecticides, wear a mask and wash your hands promptly. Slow-release granular insecticides are recommended, which can be mixed into the soil to play a preventive role.

Coal stain disease. If you find that some leaves are suddenly blackened and covered with a layer of black mold, it must be coal stain disease, because it may cause the whole plant to turn black and rot, if you find it, you should remove the diseased leaves in time, and strengthen ventilation is the key. At the same time, it is necessary to do a good job of insect control and spray some fungicides.

Fungal infections. There are also some inexplicable leaf drops, the stem or the root of the leaf is black, or it has not yet turned black, but the leaf falls off with a slight touch. This is also a phenomenon of fungal infection.

Think about whether it's been a lack of ventilation lately, or if you've been watering too often. This situation is very easy to happen in summer, and the planting material must be selected with good air permeability.
