Diseases of onion and their treatment with folk remedies with photo

Many gardeners grow onions in their summer cottages. This vegetable is popular as it is often used to prepare various dishes. When growing onions, some are faced with serious diseases that prevent the plant from growing normally. Therefore, before planting a vegetable, you should familiarize yourself with onion diseases and their treatment.

The most common onion diseases

Frequent illnesses are the main cause of poor vegetable crops. Onions also often suffer from diseases and are exposed to viral and bacterial diseases. They stop the growth of the vegetable and often lead to the death of the grown bushes.To get rid of onion diseases, you should properly fight them.

Onion downy mildew or powdery mildew

Often, onion bushes suffer from peronosporosis or powdery mildew, which is considered a rather dangerous disease. Each vegetable grower should know the features of the manifestation of the disease in order to start treating the plant in a timely manner. The disease is distinguished by the following external signs:

appearance of white spots on the surface of the sheets;
yellowing of bottom sheet edges;
plaque on sheets;
gradual drying of bushes.

This onion disease appears due to an infection on the bulbs, which gradually spreads to the rest of the bush. Infection appears if the gardener did not follow the rules of crop rotation or planted raw seed.

Peronosporosis manifests itself in conditions of high temperature, when the air warms up to 20 degrees. At lower temperatures, the disease develops much more slowly.

Onion rust

Another common disease that crops are susceptible to is onion rust. This disease appears as a result of exposure to a fungus that spreads to the feathers of a plant. Over time, they are completely covered with a yellow coating and small fungal spores. If the bushes are not cured in a timely manner, the plant will stop developing and the bulbs will stop ripening.

In order not to have to deal with the treatment of bulbs and their yellow feathers, you need to properly care for the plant. Bushes are watered only at the root, so that the liquid does not fall on the leaves. Also, the soil is periodically fed with mineral and organic fertilizers to improve the he alth of the vegetable.

Fusarial bottom rot

If the soil is not cultivated before planting a vegetable crop, the onion will become infected with Fusarium rot. This disease appears due to an infection that has penetrated into the root crop from the soil. Most often, infection occurs at the time of active growth of the bulb.

Causes of infection include:

too frequent wetting of the soil;
untimely harvest;
harvesting in rainy weather;
overheating soil due to dry weather.

When the disease manifests itself, measures must be taken immediately to stop the further development of the infection. For this, diseased plants are immediately plucked and removed from the site. Then the damaged bulbs and beds are sprayed with Bordeaux liquid.

Onion neck rot

With high humidity, onion bushes suffer from neck rot, which affects the necks of the bulbs. The disease does not appear immediately, but only after harvesting from the site. Determining that a plant has this disease is quite simple. The scales and neck of the onion heads turn pink and become waterier. Over time, the disease progresses, and the entire surface of the fruit is covered with gray mold. If the affected fruits are not treated with anything, they will become covered with a black bumpy crust.

In order not to fight rot in the future, onion disease is eliminated in the garden. To do this, the site is regularly treated with top dressing and cleared of weeds.

Wet bacterial rot and black rot

At the final stage of the growing season, the crop is more likely to suffer from black and wet rot viruses. Due to these diseases, small dark-colored wounds form on the feathers of planted plants.Without timely treatment, the disease progresses and spreads to the fruits, completely destroying them. Affected bulbs become rotten and smell bad.

The reasons for the development of rot include:

improper loosening of the soil, due to which the bulb is damaged;
dramatic weather changes and high humidity;
damage to bushes by ticks or onion flies, which are carriers of the disease.

When the first signs of disease appear, affected plants should be removed immediately to stop the spread of rot.

Onion Mosaic

This disease affects onion sets in the garden, causing yellow spots to appear on the feathers of the plant. Infected bushes gradually fall down and grow more slowly.

In some cases, the disease affects the shape of the fruit. Infected bulbs elongate and become much thinner than he althy ones. They are also worse stored, as they quickly germinate and rot. Onion greens and other vegetables become infected with mosaic due to aphids, mites and nematodes that carry the infection.

To protect plants from mosaic, only he althy seeds should be planted. Also, for prevention, the upper part of the bulbs is periodically cut off.

Green moldy rot

Vegetables in the garden often suffer from green moldy rot, which affects the fruit. You can notice the manifestations of the disease on the bulbs of affected plants. They wither, watery brown or yellowish spots appear on them. Over time, the bulbs soften and develop an unpleasant musty smell. In infected plants, leaves also suffer, which become covered with yellow spots and wither.

The development of the disease is activated after harvesting, since it is during storage that infected fruits quickly become stained and begin to rot.

Treatments

It is recommended to deal with onion diseases in a timely manner to stop their further development. There are various methods to combat viral and infectious plant diseases. Often, special means for processing vegetables are used for this.

It is recommended to use Phytofterm, which is effective in the fight against infections and pests. Before using this drug, a working solution is prepared. To prepare it, about 15 grams of the drug is added to ten liters of water. Before spraying the bushes, the soil should be thoroughly loosened so that the liquid is better absorbed by the soil. Process vegetables with Fitofterm should be in the evening, in calm weather. When processing one bush, at least a liter of solution is consumed.

Some are treating onion diseases with folk remedies. For example, vegetable growers use tobacco infusion. To prepare it, 10-12 liters of warm water is mixed with 450 grams of tobacco. Before use, the mixture is infused for two days, after which it is boiled for an hour and a half. The bushes are sprayed with the prepared product three times a week.

Prevention measures

Not only disease control, but also prevention should be carried out. This will significantly reduce the likelihood of disease in the vegetables grown on the site.

To reduce the risk of occurrence and development of diseases in onions, the following preventive measures are carried out:

prematurely process seed so that it does not contain pathogens;
before planting, they disinfect and treat the area where vegetables will grow;
keep crop rotation to protect plantings;
do not use plant remains as compost.

Conclusion

Vegetable growers who grow onions on their plots often encounter vegetable diseases. To cure and protect onion bushes, you should become more familiar with the features of common diseases and their treatment methods.
