How to treat cabbage with ammonia against pests

Today we’ll talk about how to treat cabbage against pests using ammonia.

You will learn how to prepare a solution for treating aphids, mole crickets, psyllids, butterflies, and slugs. How to dilute an ammonia solution, and what are the safety rules when using it in the garden.

Gardening is not always easy. Each seedling requires care: fertilizing, pruning, staking. Treating cabbage against pests with ammonia will appeal to opponents of chemicals. The product is easy to buy at the pharmacy.

Ammonia in the garden

Ammonia is an aqueous solution of ammonia. It is widely used in everyday life for removing stains and for cleaning shoes and mirrors. With its help, people are brought to their senses. It has a characteristic pungent odor that is easily recognizable.

Ammonia is available in 40 ml bottles. They are made of dark glass.

Why is it useful?

It is attractive for processing cabbage for two reasons:

1. the pungent odor repels pests,
2. the substance contains nitrogen, which is well absorbed by plants.

Lack of nitrogen leads to the following problems:

• white cabbage does not grow to the required weight;
• leaves are pale green or yellow;
• Over time, the leaves dry out.

Traditionally, to solve the problem, they do not use ammonia, but an aqueous solution of ammonium sulfate, ammonium nitrate or urea. But they all significantly lose in nitrogen content.

The importance of nitrogen for cabbage growth

With a lack of nitrogen compounds, plants lose color, become faded, lethargic, stop growing, old leaves dry out quickly, and cabbage does not form a head, which leads to loss of yield. To replenish useful components, substances containing ammonia are used:

• urea;
• saltpeter;
• ammonium sulfate.

These products contain from 21 to 46% nitrogen, and ammonia up to 82%, which significantly affects plant growth. When feeding, it is important not to overuse the concentrated substance, otherwise there is a risk of burns and accumulation of nitrates in the cabbage leaves.

Features of use

Ammonia is a concentrated solution and is diluted with water. An excess of substances is dangerous, as is a deficiency.

For watering

To prepare the mixture, take 50 ml of the product per 5 liters of water.

• The resulting solution is carefully poured under the cabbage root.
• For better results, repeat treatment after a week.
• A total of 4-5 procedures will be required.
• Treatment of cabbage is stopped after signs of nitrogen deficiency disappear.

From insects

Another area of ​​application of ammonia is getting rid of pests . The Cruciferous family is affected by:

• slugs;
• snails;
• mole crickets;
• mole;
• whitefish and others.

Getting rid of them is not so easy, especially since many gardeners have a negative attitude towards the chemical industry. In this case, you should resort to folk remedies.

general characteristics

Ammonia (chemical formula NH3) is a colorless gas that, when combined with water, forms a new substance known as ammonia (NH4OH). It is a universal fertilizer that is suitable for spraying most garden and vegetable crops. The drug can be purchased at pharmacies and stores specializing in gardening tools. Many vegetable growers are puzzled by the question of whether cabbage should be treated with ammonia?

Professionals say there are benefits to this. Ammonia for cabbage is an excellent development aid. Ammonia protects against pests and helps restore previously fertile soils.

Pest Control

Watering cabbage with ammonia helps get rid of pests such as:

• aphid;
• secretive proboscis;
• ants;
• mole crickets;
• whitefish;
• slugs;
• midges.

The volatile compounds contained in the drug dissipate quite quickly. It is this smell that guarantees complete removal of insects.

Ammonia as a fertilizer

Nitrogen is an essential component for plant growth. It is part of chlorophyll, lipoids and plant organelles.

The absorption of nitrogen by plants occurs exclusively through various chemical compounds from the soil. Therefore, the process of assimilation is quite complex. Plants may experience some problems with development: the formation of ovaries slows down, the leaves lose color and become fragile. As soon as these problems appear, you need to treat the young cabbage with ammonia.

It is interesting that nitrogen is absorbed much easier and faster in the composition of ammonia than in standard organic complex fertilizers. And most importantly, the price of the medicine is much lower than garden fertilizers.

Some rules

The use of any fertilizer or treatment product requires compliance with safety regulations.

Ammonia is a conditionally toxic substance and should therefore be used with caution.

• Spraying is carried out in the morning or evening. During the daytime, the sun's rays will cause burns on the leaves.
• When preparing it, be sure to follow the proportions. Excess and deficiency of the substance contributes to the development of problems.
• Apply to the back of the leaves and root zone. Processing is carried out carefully and carefully. If necessary, the procedure is repeated after 2 weeks.
• Ammonia is toxic to humans, so it is advisable to protect your respiratory tract with a respirator and your hands with protective gloves.
• It is better to prepare the mixture outdoors, as there will be a strong smell indoors.

Dry leaf pollination

Early in the morning, the foliage and soil around cabbage, radishes, lettuce, and radishes can be sprinkled with one of the suggested products:

• mothballs;
• ash and tobacco dust (1:1);
• slaked lime and ash (1:1);
• wood ash and ground black pepper (2:1);
• tobacco dust (per 100 sq. m. – 500 g);
• powders of tansy, celandine or wormwood.

Early in the morning the treatment is carried out so that the products stick to the leaves, since there is still dew on them. In the evening before this treatment, spray the foliage with water.

Ways to get rid of pests

Various insects attack plantings even at the seedling stage. Therefore, it is necessary to get rid of them in a timely manner, otherwise the entire cabbage crop will die.

From slugs

Snails and slugs cause serious damage to seedlings. Their activity peaks at night. Therefore, you may miss the moment of their mass distribution.

An aqueous solution of ammonia can solve the problems.

To make it, take ammonia and water (proportions: 40 ml per 6 liters).

1. The lower part of the leaves is sprayed with an ammonia solution and then poured into the root zone.
2. Afterwards it is left for half an hour, and the procedure is repeated in the same sequence.
3. Slugs and snails will begin to crawl out to escape the pungent smell. The gardener needs to collect them and take them to the forest.

This treatment is safe and does not harm the plantings.

From white butterflies

Beginning gardeners will love the swarm of small white butterflies. In fact, these are dangerous ones - whitefish. The voracious caterpillars will quickly destroy the cabbage. You can get rid of them with vinegar or ammonia.

A bucket of water will require 1 tbsp. vinegar essence and 50 ml of ammonia.

1. All seedlings are sprayed with the resulting solution and this is done in the evening. You cannot pour the mixture onto the beds.
2. Treatment is carried out several times during the summer.

Cabbage cutworm larvae are especially active in July . They infect cauliflower by chewing tunnels in it and depositing excrement inside. The ammonia infusion has a pungent odor and repels them.

How to feed a plant

To provide root feeding, water the cabbage with a mixture of 6 tbsp. alcohol, which are combined with 10 liters of water. To treat seedlings before planting, mix 10 ml of the product with 10 liters of water. Pour the solution into the indentations; each will require 500 ml of solution.

Safety precautions when working with ammonia

Since ammonia is an extremely dangerous substance, it can also harm humans. The following precautions must be observed.

1. Prepare a respirator, which is a gauze bandage. This will protect the upper respiratory tract.
2. Wear clothing and gloves that cover your hands as much as possible.
3. It is advisable to dilute the solution outdoors, or in a well-ventilated building.
4. The substance must not be combined with components containing chlorine.
5. Ammonia can cause a sharp increase in blood pressure; hypertensive patients should not interact with it.

You need to keep ammonia in a place inaccessible to children and animals. If you inhale the strong smell of ammonia, you may stop breathing.

From aphids

Many insects are well camouflaged and difficult to notice right away. Aphids have a pale green color that blends in well with cabbage leaves.

Preparing the solution

It can be detected by its characteristic eaten away surfaces. After which the leaves curl and dry out. Young seedlings die. To get rid of aphids you will need ammonia.

• First take a standard bar of laundry soap and rub it on a fine grater.
• The shavings are dissolved in 10 liters of warm water.
• At the end, add 3 tablespoons of ammonia.

1. The resulting mixture is sprayed onto cabbage leaves. Soap creates a protective film.
2. The treatment is repeated after 2 weeks.

Prevention

Toothpaste is an excellent preventive measure.

1. To do this, a standard tube is dissolved in a bucket of water.
2. All cabbage is treated with the solution.

When to carry out treatments

As soon as radishes, radishes, and cabbage shoots appear (if you grow cabbage seedlings in a greenhouse), the cruciferous flea beetle immediately appears on them.
Leaf beetles readily eat newly planted young seedlings. Flea beetles especially love hot, dry weather. But in cool, humid weather their activity drops significantly. Tip No. 1. It is better to plant seedlings in wet weather and immediately cover them with covering material. It is recommended to do sowings as early as possible and also cover them with film. When the plants grow and become stronger, insects will no longer be able to handle them.

However, shelter does not always help, so immediately upon emergence or after planting seedlings, gardeners and gardeners treat the plants with special solutions or dry agents.

Damage by cruciferous flea beetles is especially dangerous during the first true leaf. The bug will willingly “eat” the young first leaf, thereby damaging the growth current. As a result, the plant will die.

For cabbage, the cruciferous flea beetle is also dangerous during the setting of heads of cabbage. During this period of time, it is imperative to protect plants from pests.

From the psyllid

The psyllid feeds on cabbage juice and infects seedlings. A characteristic sign of damage is curled leaves.

1. As a preventive measure, many gardeners stretch a rope between the beds, which is generously moistened with ammonia. The pungent odor will repel insects.
2. If heads of cabbage are damaged, the leaves are treated with an aqueous solution of ammonia (50 ml of alcohol and 10 l of water). This solution gets rid of pests from Chinese cabbage.

The appearance of any insects and other parasites is difficult to notice. Therefore, it is necessary to regularly inspect the seedlings and carry out treatment. If the spread is serious, the diseased cabbage is destroyed.

By using this powerful solution you help plants, increase productivity and get rid of pests.

Advantages and disadvantages of the product

The use of ammonia against cabbage pests involves a number of positive and negative features. Getting to know them will help you make your choice.
