Biological preparations
If we are talking about a small private farm, then folk methods of pest control are best suited for cultivating a vegetable garden. But if the invasion has become widespread, experts know what to do and how to process the plants.
If traditional methods have not yielded results, biological fungicides cannot be dispensed with. The choice of chemicals should be carefully and carefully. They must be safe for human health.

At the stage of detecting onion worms, you cannot hesitate. In this case, it is advisable to use the drug Trichodermin.
Before using, you should carefully study the instructions and recommendations from the manufacturer on how to get rid of the pest. The solution is prepared in the following proportions: 3 liters of water are taken for 3 g of the substance.
The prepared mixture must be treated with plants. Watering is not recommended immediately after spraying, so as not to wash off the active agent from the pen.
After 10 days, the culture is sprayed again. If the larvae reappear, then it is worth carrying out additional processing.
Metronidazole
This drug is available as a tablet at a pharmacy. The tool has antimicrobial and antibacterial effects. Before using, it is worth studying how to properly prepare a solution for processing a vegetable garden.
The drug is effective both against onion flies, nematodes, and against a number of similar pests. It is sometimes not easy to remove insects, various antiparasitic methods and methods of control are used for these purposes. Metronidazole has established itself as an effective treatment for a variety of vegetable crops.
A solution is prepared for spraying. 4 tablets are dissolved in 10 l of water. The beds are poured with liquid. The solution can also be sprayed. If the damage to the plants is large-scale, it is recommended to repeat the procedure after 10-15 days.
Folk remedies
Most gardeners try to use natural pest control products. Using folk methods, you can improve the condition of the soil, disinfect it and nourish it with useful substances.They increase the immunity of plants and help fight various types of diseases, fungi and insects.
Traditional methods are different. Therefore, you can choose how to process onions from worms in an onion based on what is at hand, and from which the worms will forever leave the garden.
Ammonia
For the treatment of bulbous heads, ammonia is widely used. Its pungent smell scares away insects from tubers and foliage.
It is not difficult to prepare a solution. To do this, it is worth preparing 10 liters of settled water and diluting 60 ml of ammonia in it.
Re-processing can be carried out no earlier than a month later. The ammonia tends to erode and wash out of the soil, so the procedure can be performed 2 times per season.
Planting carrots and tomatoes
Sometimes, in order to get rid of a particular type of harmful insects, it is enough to plant carrots and tomatoes in the beds. The onion fly and its larvae cannot stand the neighborhood with these vegetables, so they should be planted in close proximity to the onion beds.
For the purpose of prevention, the culture is treated with antimicrobial substances against fungi and pests.
Saline solution
Table salt can be found in the home of any gardener. The saline solution is effective against a large group of pests. If insects have settled on the ground, eat onions and actively reproduce, then this method of struggle becomes a real salvation for the vegetable grower.
Brine can be sprayed and watered over the beds. It is more advisable to introduce liquid into the soil, since insects lay the larvae in the soil.
The beds are processed in 3 stages:
- The solution is prepared in the following proportion: for 10 liters of water, take 300 g of salt and stir thoroughly. Spraying is carried out in the morning. It is advisable that the weather is cloudy.
- The second time the affected area of the garden is sprayed after 2 weeks. A solution is prepared from 10 liters of water and 400 g of salt.
- The final treatment can be carried out one week after the second. The solution now consists of 10 liters of water and 600 g of salt.
Soap solution
A good plant antiseptic is a solution made from soap. The composition is extremely simple: 10 liters of water and 200 g of solid soap crushed on a coarse grater are taken. You can take warm water to quickly dissolve the soap chips. Then the liquid should cool down to room temperature.
The tool can be used no more than 3 times per season. If we pour the solution on the ground, then all the bulb fly larvae deposited in the soil will die.
You can spray the plant with it. Soap solutions are agents that repel insects with their smell and do not allow them to settle on the plant.
Dandelion decoction
Dandelion is able to remove harmful larvae and insects from the garden for a long time, but first you need to correctly make a decoction from it.
Preparation will take several days, since the solution must be infused for a long time. For 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 l by adding water to it. Spraying with infusions gives excellent results when used in tandem with saline solutions.
Wood ash
The tool is widely used in gardening. Ash is not only an antiparasitic agent, but also an excellent alkaline soil fertilizer. It can be purchased in specialized stores or obtained by yourself by burning branches, tree bark and roots. Ash from fires in which household waste is burned is not suitable for these purposes.
The mixture is easy to prepare. 2 kg of wood ash are dissolved in 10 liters of water. Pour the onion under the root with this composition, or simply spray the liquid over the entire affected area of the earth.
Potassium permanganate
The agent has a wide spectrum of action.The drug not only helps to get rid of worms, but also removes fungi and other infections from the soil. If the onion is affected not only by an onion fly, but also by a 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, the procedure is repeated in the same sequence.
Many gardeners soak seed material before planting in a solution of potassium permanganate.
Copper oxychloride
It is necessary to treat the plant with a 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 lump soap, crushed on a grater.
The effect of the procedure lasts for a long time. The worm will not disturb the growing vegetables until the end of the season.
How to pour the onion from the worm, each gardener chooses individually. There are many methods and tools that can help in the fight against this problem.
I recommend spraying the soil and the planted seedlings with Metronidazole. This will prevent the appearance of such parasites. Also, for better growth of onion seedlings, use the bioactivator "BioGrow».
