Folk remedies

It is worth paying attention to the following recipes, which are quite effective in the fight against onion fly:

1. A salt-based solution is an effective treatment during the growing stage of onions, when the first few feathers have already appeared. That said, the saline solution is very easy to use and prepare. It is necessary to take water in proportion to salt - 10: 3. Stir everything vigorously until the crystals are completely dissolved. With the resulting composition, you just need to water the beds. Processing is carried out twice with an interval of approximately 15-17 days.
2. Potassium permanganate solution. It is necessary to dilute several crystals of potassium permanganate in warm water. The concentration should be such that the liquid turns out to be light crimson. It is necessary to soak the plant bulbs in it before planting them. Soaking lasts no more than 15 minutes. Also, this water can be used later in order to water the plantings.
3. Another effective way to deal with onion flies in the garden is to use ammonia. To prepare this recipe, you need to take 3 tablespoons of ammonia and dilute them in 10 liters of cold water. This solution should be used to water the planting of onions, garlic or bulbous flowers at the root.
4. There is also another recipe to which iodine is added. In this case, you can get rid of not only the onion fly, but also protect the planting from other pests. For its preparation, it is necessary in the same volume, that is, in 10 liters of water, to dilute 20 ml of ammonia, add 5 ml of boric acid and drip 3-4 drops of iodine. Stir vigorously and use as a spraying on bulbous plants or directly watering under the root.
5. Wood ash will keep the plants from getting infected by the onion fly. This is one of the most effective methods in the fight against this pest, which is quite easy to use. You just need to sprinkle the beds with wood ash powder. Due to the anatomical features of this insect, wood ash negatively affects its body, as a result of which the onion fly simply will not attack the beds. But it must be borne in mind that the exposure time of wood ash is no more than 10-15 days. After that, it is necessary to renew the ash layer on the garden bed.

These remedies are effective enough to control onion flies, although they sometimes need to be reapplied for best results. But it is better to prevent the problem than to deal with it. Therefore, you need to know about those folk tips that help to avoid the appearance of onion flies in the garden.
