Is the black slag on top of the newly bought succulent dirt or germs?

In the process of raising succulents, I found that there were small black spots or black wires on the back of the leaves, and I didn't care about it, thinking it was normal, because the leaves did not have any adverse reactions at this time.

But this is a red flag, those black spots or black wires are likely to be an early symptom of bituminous coal disease, which can spread quickly and harm succulent growth if left unchecked at the right temperature and humidity.

The flesh is harmed by bituminous coal disease.

Succulents. Bituminous coal disease will not kill it easily, but it will spread quickly and affect the growth of the whole plant. Bituminous coal disease begins on the dorsal surface of the succulent leaves, near the branches, with small black dots or black threads.

Over time, small dots and black threads will spread quickly, not only on the back of the leaf, but also on the front side. These black things affect the leaves to photosynthesize.

Problems such as deformation and falling off of leaves slowly appear. Bituminous coal disease is severe and succulent, and all the leaves will fall off, and eventually the whole plant will die. Therefore, succulent bituminous coal disease does not directly cause succulent death, but it is more likely to cause indirect death.

What to do if you have bituminous coal disease.

Mild bituminous coal disease.

If you find that there are black spots or black threads on the back of the leaves of succulents, but they are not serious, spray fungicides and insecticides in time, ventilate more, and get proper light, and the situation will gradually improve. If the black spots and black strands on some leaves are obvious, you can break those leaves off to prevent more leaf infections.

Severe bituminous coal disease.

If most of your succulent leaves are infected, and there are many black spots and black threads on the front and back of the leaves, you need to break off all the diseased leaves, and then spray fungicides and insecticides on the whole plant**. The plants are relatively small and succulent, and after breaking off the infected leaves, the whole plant can be soaked in fungicides to completely sterilize. Bituminous coal disease is severe and succulent, and the ** cycle will be longer, but as long as there is no problem with the plant itself, timely treatment can still slowly recover.

If your succulent root system is not good, you are sick, and you are infected with bituminous coal disease, and you are likely to die.

Why do succulents have bituminous coal disease to use insecticides.

There are two kinds of succulent bituminous coal disease, one is spread by various pests, and the black silk and black spots are only attached to the surface of the leaves, which can be wiped off or washed. Only put the source of transmission greasy insects, scale insects.

Kill, bituminous coal disease can be controlled naturally. The other has little to do with insects, black silk and black spots are attached to the fleshy leaves, which cannot be wiped off or washed, and are very stubborn. This is the spread of germs, which can only be controlled with fungicides.

Therefore, if a succulent plant has bituminous coal disease, it is necessary to carefully check for insects. In most cases, the succulent bituminous coal disease of the flower friends is accompanied by greasy insects or scale insects.

Bituminous coal disease can occur repeatedly.

Once succulents have bituminous coal disease, there may be outbreaks every year. In particular, some varieties that are themselves susceptible to bituminous coal disease, such as rainbow jade.

Orioles, Chihuahuas.

As long as Hongzhilian and others have had bituminous coal disease once, it is likely that it will break out again at that time in the next year. Therefore, to raise these succulents that are prone to bituminous coal disease, we must do a good job of prevention, and the air humidity in summer.

When it is high, it is necessary to take the drug.

I don't raise sedum succulents, but the black slag you said can get rid of when washed with water. Plaque cannot be washed off, and the epidermis will also be eroded where the lesion is present.

You can buckle it with your hand and see if the black slag can be deducted, and it's easy to tell.

Judging from the **, the succulent tip is a little discolored, but it is neither frostbite nor pests and diseases, and the growth is still very normal. You can observe for a while, don't water too often, succulent and afraid of waterlogging, you can water it once a week or so, if there is no change, it is normal growth.

If on the way home, do not do a good job of adequate heat preservation, the buttocks of succulents are easily affected by the smell of the wind, causing local frostbite, pay attention to observation, water more, the situation will allow to change.

From the fleshy **, frostbite is not a worm disease, it should just be a simple lack of nutrition.

If you can afford to buy what you like and go where you want to go, you will not lose the quality of life because of the people around you, but you will be more confident because you spend your own money, which is why you should work hard.

The electrostatic precipitator is a device that collects dust in flue gas by electrostatic purification method. It is an ideal equipment for purifying industrial exhaust gases. Its net profit work mainly relies on two systems: discharge electrode and precipitation electrode.

When the electrode space of high-voltage direct current is input between the two poles, anions and cations are generated, which act on the surface of the exhaust gas dust particles passing through the electrostatic field, move to the electrodes of opposite polarity under the action of the electric field force, and deposit them on the electrodes to achieve the purpose of dust collection. The two-pole system has a rapping device, when the hammer type periodically knocks the two-pole device, the dust adhered to it is shaken off and falls into the lower ash hopper and discharged out of the machine through the ash discharge device. The purified exhaust gas is discharged into the atmosphere through the chimney from the outlet, and the flue gas purification process is completed at this time.

Based on your description, it could be concluded that the Succulent Mage may have a disease or infestation.

If the flesh is infected with black spot or black rot, small black spots will grow on the leaves. How can you tell the difference? Black spot tends to start on the leaves, where black round spots often appear, and then slowly expand and gradually infect other parts of the flesh, causing the entire flesh to die.

Black rot is different from black spot in that it tends to start from the bottom of the leaves, and the surface of the leaves will be yellow at first, and then slowly turn black when severe. The disease will spread from the bottom leaf to the upper leaf, and black rot is often accompanied by leaf water, so the leaf disease site is often translucent and watery.

Whether it is black spot or black rot, once found, it needs to be isolated for a while. First observe what kind of disease the flesh has, and then prescribe the right medicine according to the symptoms. Carbendazim or chlorothalonil are generally used, but whether it is black rot or black spots, it is more difficult to treat in the later stage of illness, and it depends on the vitality of the flesh after the medication.

It is also very simple to prevent it, in the usual maintenance, we must pay attention to the ventilation of the environment, and avoid letting the succulent in a hot and stuffy environment. Be careful not to water too often, especially in summer. You can also spray the fertility leaf amino acid foliar fertilizer appropriately to enhance the resistance to pests and diseases, and carefully check whether there are insect pests in the soil when repotting the succulents, and kill insects in time if insect pests are found. Once small black spots are found on the leaves, they should be isolated in time to avoid infecting other healthy succulents.

This is caused by a disease.

You can buy some carbendazim to spray the water.

However, this weather mage is dormant, so you can plant it first. A small amount of water that is moistened with soil will do.

There are two possibilities, one is that the sun has more long spots, don't worry about him, it will pass quickly. The second is the rotten spots that appear after watering too much. If it is the latter, it can be observed, as long as it does not continue to spread and water less, it will soon get better.

This should be said to be bruised, and the flesh should be kept in a ventilated and cool place with the sun, but remember to avoid exposure to the sun and water less in summer.

The succulent that has just been taken out and raised in the open has a piece of black on it, and it feels like the succulent is sick, which may be black rot caused by high temperature and lack of ventilation, pay attention to isolation.

This succulent plant should not be taken out.

It's good to keep it indoors.

Don't listen to others about what to do in the open, it is easy to get sunburned, or it is damaged by rain.

The succulent is very easy to live, and when it is alive, you can remove the black part and grow new leaves.

It's best to spray both. The leaves are sprayed directly to kill bacteria, and spraying the soil can kill the bacteria in the soil.

Succulents refer to plants that have at least one of the three vegetative organs of the root, stem, and leaf of a plant that is thick and juicy and has the function of storing a lot of water. The white is perlite for decoration, which can be used as a substrate for Wenpei plant-style cuttings, which is loose and transparent, light in temperament, and has good water absorption. This perlite is not a major nutrient.

On the one hand, it is added to the basin to increase the permeability of the soil, and on the other hand, it is conducive to the rapid penetration of water.

Can the purchased general nutrient soil be used directly?

When planting flowers and plants, many people choose to buy universal nutrient soil because they don't know what soil is suitable for them. But I want to tell you that nutrient soil is not recommended to be used directly. Although the universal nutrient soil is rich in nutrients, it will inevitably contain some bacteria and vitamins, so it is best to use it after being disinfected by sun exposure.

In addition, the universal nutrient soil is specially configured to meet the growth of flowers and plants, although it contains a variety of nutrients, it also has strong water and fertilizer retention. Pure nutrient soil is often either too wet or too dry, and it is best to mix some vermiculite and perlite in it, so that flowers and plants grow better.

Another point that everyone needs to pay attention to is that many people should pay attention to the selection when buying universal nutrient soil. The quality of some nutrient soils on the market is often uneven, and there is no strict control, and even some are directly processed from waste materials. Therefore, it is best to choose a regular sales channel to buy when choosing, and pay attention to disinfection when buying.

Can you boil water for disinfection of newly bought succulent nutrient soil Can you boil water for disinfection of newly bought succulent nutrient soil. Can you boil water for disinfection of newly bought succulent nutrient soil I don't think that's necessary, and the succulent nutrient soil that I generally buy is prepared in batches and batches, and there is no need to sterilize.

The current weather is not suitable for planting, wait a few days or the amount is not large, put it in the microwave oven hot, you can also take potassium permanganate to soak and sterilize, and mix insecticides in the soil before planting just in case.

During the epidemic, it should be disinfected for the safety of yourself and your family.

The jumping insect is an insect of the order Springtail, which resembles soot when dense, and is also known as soot insect. Jumping insects mostly occur on the culture material, often dense on the surface of the mushroom bed or in a dark and damp place, biting and eating the fruiting body of the mushroom, causing small holes, and carrying and spreading miscellaneous bacteria. This insect reproduces very quickly.

It feels like a little black fly.

You can use flower protection spray + root irrigation, but also isolate from other flower pots, this small flying insect can also be driven away by mosquito coils, but there may be larvae in the soil, and it is best to use some insecticides.
