Ammonia
Ammonia is widely used for processing onion heads. Its pungent smell repels insects from tubers and foliage.

Repeated treatment can be carried out no earlier than a month later. Ammonia tends to erode and be washed out of the soil, so you can carry out the procedure 2 times per season.
Planting carrots and tomatoes
Sometimes, in order to get rid of a particular type of harmful insect, it is enough to plant carrots and tomatoes in the beds. The onion fly and its larvae cannot stand the proximity of these vegetables, so they should be planted in close proximity to the onion beds.
For prevention purposes, the crop is treated against fungi and pests with antimicrobial substances.
Saline solution
Table salt can be found in the home of any gardener. Saline solution is effective in controlling a large group of pests. If insects have colonized the ground, eat onions and actively reproduce, then this method of control becomes a real salvation for the vegetable grower.
You can spray and water the beds with a saline solution. It is more advisable to introduce liquid into the soil, since insects lay larvae in the soil.
The beds are processed in 3 stages:
- The solution is prepared in the following proportion: take 300 g of salt per 10 liters of water and mix thoroughly. Spraying is carried out in the morning. It is advisable that the weather be cloudy.
- The affected area of the garden is sprayed a second time after 2 weeks. The solution is prepared from 10 liters of water and 400 g of salt.
- The final treatment can be carried out a week after the second. Now the solution consists of 10 liters of water and 600 g of salt.
Soap solution
A good antiseptic for plants is a solution made from soap. The composition is extremely simple: take 10 liters of water and 200 g of solid soap, crushed on a coarse grater. You can take warm water to quickly dissolve soap shavings. Then the liquid should cool to room temperature.
The product can be used no more than 3 times per season. If we pour the solution onto the ground, then all the onion fly larvae deposited in the soil will die.
You can spray the plant with it. Soap solutions are products that repel insects with their smell and do not allow them to settle on the plant.
Dandelion decoction
Dandelion can permanently remove harmful larvae and insects from the garden, but first you need to properly make a decoction of it.
Preparation will take several days, since the solution must infuse for a long time. For the tincture, you need to take 200 g of finely chopped dandelion root and pour 1 liter of boiling water. The mixture is infused for exactly 2 days. Then the solution is brought to a volume of 10 liters by adding water to it. Spraying with infusions gives excellent results if used in conjunction with salt solutions.
Wood ash
The product is widely used in gardening. Ash is not only an antiparasitic agent, but also an excellent alkaline fertilizer for the soil. It can be purchased in specialized stores or obtained independently by burning branches, tree bark and roots. Ash from fires in which household waste is burned is not suitable for these purposes.
Preparing the mixture is quite simple. 2 kg of wood ash is dissolved in 10 liters of water. Pour this mixture over the onion at the root, or simply spray the liquid over the entire affected area of the ground.
Potassium permanganate
The product has a wide spectrum of action. The drug not only helps get rid of worms, but also removes fungi and other infections from the soil. If the onion is affected not only by the onion fly, but also by the virus, you can safely use a manganese solution to eliminate the problem.
Initially, the solution is made weak. Each subsequent one should be more concentrated. Processing takes 2 days. On the first day, the beds are watered and sprayed. On the second day after simple watering, repeat the procedure in the same sequence.
Many gardeners soak seed material in a solution of potassium permanganate before planting.
Copper oxychloride
It is necessary to treat the plant with the substance in the morning. To prepare the solution, you need to take 10 liters of water, dilute 20-22 grams of the drug in it and the same amount of grated bar soap.
The effect of the procedure lasts for a long time. The worm will not disturb the growing vegetables until the end of the season.
Each gardener chooses what to water the onion from the worm individually. There are many methods and means that help combat this problem.
