Why are all the pomegranates growing in pomegranate trees rotten?

The pomegranates on the pomegranate tree are all rotten, you take a closer look and open the fruit to observe. Generally, there are two situations, one is attacked by germs, and the other is eaten by insects.

Pomegranate pest damage, fruit cracking and mechanical damage can lead to fruit rot, the main diseases are dry rot, brown spot and fruit cracking, etc., the main insect pests are peach borer, peach heartworm, etc., can be applied in time with drugs**.

How pomegranate trees are maintained.

1. Watering: When potting pomegranates, keep its potting soil slightly moist, and do not need to water too much. Be careful not to pour water on its flowers when it is in bloom.

2. Fertilizer: It doesn't need too much fertilizer to fertilize, and liquid fertilizer is applied every half a month or so. After fertilization, water is poured to make it fully penetrate into the soil to ensure that it needs to grow.

3. Light: It needs good enough light to maintain, if the light is insufficient, there will be small branches, yellowing leaves, and a lack of light for a long time may not bloom and bear fruit.

4. Temperature: The growth environment of 15-25 is the most suitable for its growth, and the flowering and fruiting period is to ensure that the ambient temperature reaches the standard. If the ambient temperature is below 15 for a long time, it will cause the branches to grow and reduce the number and quality of fruit set.

Differences between different varieties, some varieties of pomegranate may crack and bad seeds when encountering environmental conditions that are not conducive to their growth; Insufficient moisture temperature and light conditions may also lead to the phenomenon of cracking and bad seeds after pomegranate ripening to a certain extent. Most of the pests and diseases that act on pomegranate fruits will cause pomegranates to have more or less cracked fruit and bad seeds.

When controlling fruit tree pests and diseases, all we should consider is to choose and plant highly resistant varieties, which can not only prevent pests and diseases, but also leave us with a lot of troublesome things in the later management process of fruit trees.

Of course, the planting of pomegranate trees is no exception, in the face of a series of phenomena such as pomegranate tree cracking and bad seeds, the primary consideration is also to plant pomegranate trees with high resistance to broken fruit and bad seeds, in fact, this method is also the most reliable and simple method of orchard planting.

Cultivation Techniques:

It can be planted or repotted after the leaves fall in autumn and before budding in the following spring. Ground planting should be selected in a sunny, leeward, slightly high place, and the soil should be loose, fertile and well-drained. The potted plants are made of humus, garden soil and river sand, and an appropriate amount of well-rotted organic fertilizer is added.

When planting, it is necessary to bring soil mass, properly stub and prune the above-ground part, water thoroughly after planting, put it in the shade for maintenance, and move to a ventilated and sunny place after germination and survival.

Light and temperature are important conditions for flower bud formation. The growing season requires full sunshine, and the more sunlight there is, the more flowers will be more vivid. The leeward, sunny, dry environment is conducive to flower bud formation and flowering. When the light is insufficient, it will only grow leaves and not bloom, which will affect the ornamental effect.

1. The cause of rotten fruit.

Pomegranate pests and diseases, fruit cracking and mechanical damage can lead to fruit rot, the main diseases are dry rot, brown spot and fruit cracking, etc., and the main insect pests are peach borer, peach heartworm and so on.

2. Prevention and control measures.

1. Clear the garden in winter. After pruning in winter, remove the branches and leaves, rotten fruits, and stiff fruits of the diseased insects in time, scrape off the old warped bark, diseased and insect spots on the trees, and bury or burn them deeply to reduce the source of diseases and insects. After falling leaves to before germination, the whole garden is sprayed with a Baume 3 5 degree stone sulfur mixture, and the trunk is whitened, and the whitening agent can be prepared with 10 parts of quicklime, table salt, 2 parts of stone sulfur mixture, 40 parts of water, and 2 parts of clay.

2. Fruit management. After thinning the fruit and setting the fruit, the fruit calyx tube was blocked with 50% phosphine 100 times solution and 70% methyl tobuzine 800 times liquid cotton wool. After spraying a sterilization and insecticide in the whole garden, the fruit is bagged, which can effectively prevent and control pests and diseases and mechanical damage, and reduce fruit cracking.

3. Pharmaceutical prevention and control. During the growth period of pomegranate, spray 40% carbendazim 800 times or 70% methyl tobuzine 1000 times or m 45 Dasheng wettable powder 800 times to prevent dry rot and brown spot disease; In the first half of May, sprinkle the ground with phosphine poisonous soil or spray 50% phosphine 100 times solution, and turn the garden soil shallowly to mix the medicinal soil to control the overwintering larvae of peach borer and peach heartworm. Then, according to the insect situation, spray 50% phosphine 1500 2000 times or 3000 5000 times the enemy kill every 10 15 days in mid to late May to prevent and control.

For the sake of the birds. Birds will eat pomegranates, and if they open for a long time, they will give birth to insects.

It's a matter of variety.

It is probably caused by the improper grafting of the pomegranate tree species.

It is advisable to pick up new varieties.

It is because there are insects in it, which causes the fruit to die.

The special structure of the pomegranate peel causes the pomegranate to rot in the rain or in a humid environment, and it is best to take bagging cultivation after using fungicides to effectively prevent rot.

Pomegranates should be thinned with flowers and fruits, and smeared with medicine after flowering. In winter, the garden should be cleared, rotten fruits should be removed, the trunk should be scraped, and dead branches, broken branches, and erect branches should be pruned to prevent rot and heart-eating insects.

What is the reason why the pomegranate rots on the tree, and how**.

The pomegranate tree is a fruit tree with many pests and diseases, and every year farmers will suffer some yield reduction due to these diseases, and in severe cases, it will lead to no harvest. Let's take a look at some common diseases of pomegranate trees, so that you can judge the disease varieties by yourself when you get sick, so as to prevent them after the disaster.

Pomegranate stalk window moth.

1. Pomegranate stem window moth.

This is a very harmful insect in the larval stage, the mother lays eggs on the branches of the pomegranate tree, and its larvae are fed with the sap of the pomegranate branches, which seriously affects the growth of the pomegranate tree. Generally, around July belongs to the onset period of Gaobu dust. The initial manifestation of the disease is that the mortality rate of new branches is extremely high, and in severe cases, old branches will also die.

In the later stages of the disease, the larvae will invade the trunk of the tree, causing the entire plant to wilt. Therefore, if farmers find that the branch death rate of the year is very high, they should pay attention to pomegranate stem window moths. It is recommended to clean up old and dead branches in time, and spray the plants with trichlorfon agents after the onset of the disease.

Pomegranate dry rot.

2. Pomegranate dry rot.

It is a disease caused by pathogens, and the onset period is spread throughout the flowering and fruiting stages. The onset time was mostly concentrated in the rainy season and the subsequent period of high humidity. At first, brown spots appear on the corolla of flowers or fruits, and slowly decay and spread, and finally spread throughout the fruit and flowers.

The prominent symptom of flowering is severe flower loss, and most of the flowers will be distinctly black. The fruiting stage is prominently manifested in the appearance of black rot in a large number of fruits, and there is the phenomenon of fruit loss. It can be tried with carbendazim suspension**.

Melanoma. 3. Black spot disease.

There are more black spots on the leaves of the pomegranate trees that we see every day, and the leaves will wither and fall off very quickly within a period of time after the black spots appear, which is basically caused by black spot disease. When it is severe, it will cause a large number of leaves to fall, and the pomegranate tree can no longer photosynthesize, and finally slowly wither. It is best to be prompt after discovering such a situation**, carbendazim is a good choice.

Scab disease. 4. Scab disease.

Crust disease is a disease that occurs mostly on pomegranates. It is mainly manifested that there will be some spots on the surface of the pomegranate that resemble scars, and then slowly spread, and the affected area will further dry up, and finally the whole fruit will become a dry tumor. Onset is concentrated in the early stages of the outcome, and the symptoms are obvious.

Generally, it is recommended to remove the fruit directly after discovery to reduce the pathogen, and finally use carbendazim powder**.

Hello, rot bacteria are weak parasitic bacteria, wound invasion, with latent infection characteristics. That is, the tree weakens and begins to infect. The tree is strong, and germs are lurking, and they can occur all year round.

From February to May and from August to November, there are many lesions, and the harm is serious. It is mainly caused by the invasion of rot germs from wounds. The decay of pomegranates on trees is caused by wound invasion and has the property of latent infestation.

The rot on the pomegranate tree is caused by wound invasion and has latent infection properties.

The rotten fruit of the pomegranate tree is rotten, mainly caused by rainwater seeping through the insect holes.

Once the insect body burrows into the fruit, it is difficult for the drug to enter the control, and the pomegranate with raw insects is removed as soon as possible to prevent the spread of the pest. If the pomegranate tree is overgrown with weeds, try to remove the grass to avoid a place for insect pests.

Pomegranate fruit rot is more common in summer due to diseases and insect pests.

Dry rot can affect pomegranate fruits, spraying carbendazim, methyl tobuzin, etc.

The insect pests are mainly peach borer and peach heartworm, and it can be sprayed with peach small spirit emulsifiable concentrate, enemy killing, larval urea, etc.

It should be noted that pest control should be sprayed at the fruit-setting stage, especially the fruit stalk part, which is the main part of the insect infestation.

After the pomegranate tree bears fruit, if it is caused by infection, the rotten fruit can be picked off, and the disease is sprayed with fungicide, and the ground is sprinkled with octathion. If it is caused by insect infestation, it can be sprayed with insecticides**. If it is caused by too much watering or too much rain, the watering should be controlled and the stagnant water should be discharged in time.

If it is caused by too many hanging fruits, you can remove the fruits that do not grow well on the pomegranate tree, such as small fruits, damaged fruits, etc.

If the fruit of the pomegranate tree is always rotten, it is because the pomegranate tree has too much water and there is less sunlight, and the fruit of the pomegranate tree rots before it is ripe.
