Why do beet leaves turn black and what to do?

Beet is a vegetable that is a frequent guest on a person's table, but at the same time remains capricious. What if the negative manifests itself in the state of the tops and root crops? Beet leaves themselves are juicy, therefore they are a breeding ground for pathogens of vegetable diseases. If a plant suffers from a pest attack, there is a 20 to 70% chance of disappearing. Measures must be taken to keep the roots intact.

Why does green mass suffer?

The reasons why beet leaves turn black are different. In most cases, it depends on the person. It is necessary to monitor the condition of the vegetable in order to prevent the development of any disease in time. The most common reasons why beet leaves turn black are distinguished.

Corneed

Experienced gardeners and farmers distinguish the root-eater. In addition to beets, it can also infect other plants. The causative agents are various bacteria and fungi. The following signs of the disease are distinguished:

• the foliage and the stem of the culture turn black;
• young shoots die before they can appear on the soil surface.

If the disease is in an advanced form, the amount of the crop is reduced to 45%. This is due to the lack of proper treatment.

The appearance of the root-eater contributes to:

• damage to culture by negative microorganisms;
• poor aeration of the soil;
• low level of acidity of the earth;
• poor seed quality for sowing.

It is difficult to get rid of the root eater, since it is poorly removed from the soil. Thanks to this, pests can accumulate in large numbers and subsequently spread to other vegetable crops. They persist even in the seeds that people plan to sow next season.

Beetroot becomes resistant to the pest only after the formation of the second pair of true leaves.

Fusarium rot

If the leaf petioles begin to darken at the base, it is necessary to dig up the root vegetable and examine it. The appearance of cracks covered with a white coating indicates the presence of fusarium rot. A similar picture is observed when the plant is damaged by brown rot. In the second case, instead of a white bloom, it will be brown.

To protect the beets from rot and stop the blackening of the leaves, the soil is deacidified. For this, chalk or lime is used. Areas where water stagnates are dried. Complex feeding should include a substance such as boron.

Regular loosening of the row spacings should not be neglected. Moreover, it must be deep. If a person noticed an infected plant in the garden, they act immediately. The affected bush is removed and destroyed so that the affected beet tops do not infect other plants.

People who grow vegetables often ask themselves: why do beet leaves turn black with fusarium rot? The most common problem is a lot of moisture. Many gardeners make the mistake of watering their vegetables frequently. Beets love water, but in moderation.

How often and correctly to water the beets outdoors?

At the same time, it tends to accumulate moisture and consume it in hot weather. This fact must be taken into account. Do not water the beets during the rainy season, as stagnant water cannot be avoided. The land allocated for the beetroot area should be slightly moist and not sticky to your hands.

Ascochitosis

Beets can also suffer from ascochitis. Blue-green spots appear on the leaves. Gradually they turn brown, and black dots form in the center. They are called pycnids.

To finally recognize the disease, you need to examine the seeds and root of the plant. They are also covered with dots. The causes of infection lie in the weakened immunity of the culture. Seeds and soil are pre-infested with pests, which were transferred to the soil by crop residues.

Gardeners most often encounter a similar phenomenon. Beet spots that appear on infected leaves cannot be saved. Even if a person treats with a solution, it will not restore them. Spraying will help preserve the roots.

In this case, the culture will independently try to get rid of the blackened leaf. It dries up and falls off. The vegetable produces new and already healthy leaves. Thus, the plant heals.

What to do?

The sooner the disease is noticed, the greater the chance of getting rid of it completely. The following set of rules should be followed:

1. Pay attention to general health measures that are aimed at preventing plants from diseases during the growing season and storage.
2. Do not plant a crop in the same place for several years in a row.
3. Grow only varieties that are resistant to disease.
4. Those crop varieties that need optimal nutrition, which do not receive it from the soil, suffer from great vulnerability. To do this, they balance the composition of the earth if they notice that the plant is missing something.

Uterine roots and beet seed most often they are carriers of causative agents of various diseases. This fact is always taken into account before planting vegetables. To obtain the result, the planting material is etched with protective and stimulating substances. This will not only protect the plant from the appearance of black spots on the beet leaves, but also protect it from a host of other diseases.

How to get rid of the disease?

Experienced gardeners are advised to use these rules if the beet tops begins to turn black:

1. Spray a plant that has black spots every 3 months. Medicines must contain copper oxychloride.
2. If there is a need to use Kartotsid, Bordeaux mixture or Abiga-peak.
3. Digging the ground to a depth of 20–25 cm will help get rid of the fungus. As a result, he dies.

If the hardwood is already black, you may need to remove the entire plant from the garden. In some cases, this is necessary to protect other crops from the spread of the disease. One of the important rules is the observance of crop rotation. Before planting a crop, the garden must be cleaned of the remnants of the previous vegetable, especially if the crop has already been harvested.

Preventive measures

Experienced gardeners use a little trick - they do not allow the development of any diseases. To do this, they do not neglect the rules of prevention. This is much easier to do than trying to get rid of pests, cure a vegetable and reap a rich harvest.

Preventive measures:

• Observe agricultural practices during cultivation. Take seriously the issue of seed preparation and planting in the ground.
• The leafy part of the plant likes boron fertilization. Do not disrupt the plan for feeding the vegetable.

• If the same variety has black spots on the leaves for the second season in a row, do not plant it. Better to choose another.
• Give preference to varieties that are resistant to various diseases that lead to stains on the foliage.
• Inspect seedlings every day. If spots were found on the leaves, urgently get rid of the culture before the disease attacks other bushes.
• Harvest from the beds in time. Remove leftover contaminated vegetables from the ground.
• Select root crops before winter storage.

Even if the fruits are already harvested and stored in the basement, this does not mean that everything is fine with them. A person should periodically inspect the beets and remove spoiled roots in time. The same should be done with the seeds. Throw out the spoiled ones and never plant them in the soil.

A competent approach to agricultural technology and top dressing carried out on time will make the vegetable practically invulnerable to pathogens. If the culture still could not be protected from the disease, it is important to know how to quickly correct the situation. The right treatment will save most of the crop. The experience of treatment will help not to repeat the mistakes of the gardener in the next season.
