Can the black rod survive in the spring, what is going on with the black rod in the moon

I can live. If the degree of dryness is mild, you can cut off the dead branches and leaves, and put the moon season in the shade and ventilation to maintain, and it can be restored.

There are four types of black rods in the monthly season:

1. The appearance of black rod or red stem and longitudinal crack in any part of the branch, and the white mold layer will appear when the air humidity is high, which is downy mildew;

2. What is the stem in any part of the branch, the branch is dry, and each white layer will appear when the air humidity is high, which is branch blight;

3. Black rods appear in any part of the branches, the branches wilt, and the gray mold layer will appear when the air humidity is high, which is gray mold;

4. After the monthly pruning, there is a black rod at the cutting edge, and a gray mold layer will appear when the air humidity is high, which is gray mold.

Main prevention and control methods:

1. On the day of monthly pruning, spray with 50% Pythium WP800 times + sodium nitrate AS1500 times solution to prevent and control the gray mold pile head;

2. During the growth period of the moon and quarter, spray with 69% enoylmorpholine manganese-zinc WP800 times (or 72% frosturea cyanide manganese-zinc WP800 times, 50% enoylmorpholine WG1500 times) + 50% Pythium WP800 times (or 50% iprodione SC1000 times).

If you see a bacterial infection, you should cut off the black rod immediately to prevent the infection from getting worse.

Summary. 1, check the root system It is recommended that netizens immediately take off the pot to check the root system to see if there is still an intact root system, if the blackened root system is less, only need to prune and disinfect it a little and change the pot and soil again to maintain it, if the root system is black and rotten seriously, there is almost no root system, at this time, if it is maintained again, it is equivalent to cuttings and maintenance again, which needs to promote root nourishment. 2. After pruning the root system and checking the root system, then pruning, because the roots have rotten, so the branches should also be pruned, and it is recommended to cut a little, the pruned branches can be directly taken to cuttings, and then the dead root system is pruned, after pruning off the dead root system, and then soaked and disinfected, after disinfection, it will be naturally dried to remove the water, and then potted again on the line.

1, check the root system It is recommended that netizens immediately take off the pot to check the root system of celery to see if there is still an intact root system, if the black root system is less, only need to change the pot and soil again after a little pruning and disinfection, if the root system is black and rotten seriously, there is almost no root system, at this time the maintenance is again, it is equivalent to cutting and maintenance again, which needs to promote root maintenance. 2, after trimming the root disinfection to check the root system, and then pruning, because the roots have rotten, so the branches should also be pruned, and it is recommended to cut a little, the pruned branches can be directly taken to cuttings, and then the dead root system is pruned, after pruning off the dead root system, and then soaked and disinfected, after disinfection, it will be naturally dried to remove the water, and then the suspect Wang will pot again to maintain it.

3, moisturizing and promoting the root for the rotten root is serious, almost no root situation, it is recommended to prune the root must be pruned thoroughly, prune to the place where there is no rot, prune and then use coconut peat after pruning, defeat imitation sand to bury the forest withering balance to promote the root, do a good job after the bagging insulation and moisturizing, and so on after flowering again transplant and maintain it.

If this happens, it means that the roots have festered.

Either way is to go back to the sky and replant.

It's dead! Let's plant new ones!

The top-down black rod may be infected by germs, when pruning, the wound is not disinfected in time, and the phenomenon of black rod will appear, and the plant will also suffer from insect pests.

1. Wound infection germs

There are many reasons for the black rod in the moon, which needs to be analyzed according to the specific symptoms, if the branches of the moon season appear from top to bottom, it may be that there is no timely disinfection during daily pruning, resulting in the germs entering the wound, resulting in the phenomenon of black rods.

2. Suffering from insect infestation

The appearance of black rods in the moon season may also be eroded by insect infestations, and the top shoots will be sucked by insects and have wounds, and the insects will also secrete excrement, thereby increasing the chance of bacterial infection, and the phenomenon of black rods will gradually appear in the moon season.

3. Root rot

If there is too much watering in the process of breeding, the soil is too compact, there will also be the phenomenon of rotten roots, and gradually rot from the root system, and it is necessary to prune the rotten part of the root system in time and water carbendazim, so as to improve the phenomenon of black rods.

4. Sun exposure

The black rod may also be caused by sun exposure, especially due to high temperature and high humidity, it is easy to breed bacteria when the ventilation is poor, so in the process of breeding the moon season, we must take revenge for a good ventilation environment to avoid exposure to the sun and high temperatures.

There are four situations of blackening of the pole from the top to the bottom, generally from the top to the bottom of the blackening is caused by improper pruning, and if the pole is blackened from the bottom to the top, it means that there is a problem with the root system of the moon, and at the same time, the pole will be blackened by bacteria, and if it is locally blackened, it should be the usual maintenance is not in place.

1. Black from top to bottom

There are many cases of blackening of the pole, such as the blackening from the upper part of the pole to the bottom, which is generally due to the fact that the incision is not treated when pruning the branch, so that the rain is drenched, and the treatment is relatively simple, you can cut off the blackened pole and then apply some drugs such as sterilizer on it, so that the pole that grows out later will not be blackened.

2. Blacken from bottom to top

This situation should be taken seriously, because this is much more serious than the first case, blackening from the bottom to the top means that there is a problem with the roots of the moon season or the moon season is infected with germs, which is more troublesome to deal with, you need to check whether the roots of the moon season have rotted, if the rotten area is not large, remove the rotten place as soon as possible.

3. Blackening in the middle

Only the middle part of the moon season is blackened, this situation is basically caused by bacterial infection, the problem is not particularly big, you can go to the flower shop to buy some sterilizer, spray this medicine on the pole of the moon season will ease after a while, generally the pole is blackened, it is best to remove the blackened pole and then deal with it better, to avoid cross-infection.

4. Partial blackening

The blackening of the pole of the moon season is unevenly distributed, which may be caused by the direct sunlight for too long, or the obvious temperature difference change, because the pole of the moon season can not be exposed to strong direct light and can not have obvious temperature difference changes, which will make its growth unstable, thus causing the phenomenon of blackening.
