There are legends among gardeners about the harmfulness of the onion fly.
As the expert of the online publication BelNovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh explained, the main damage comes from the larvae that hatched from the eggs laid by the onion fly.
If the plants have just been planted, the pest will suck the juice out of them, and in second-year crops, this parasite eats out the bulbs.
If you encounter a similar problem, try to solve it with metronidazole, an antimicrobial and antiprotozoal agent that should be in every summer resident’s medicine cabinet.
To get rid of onion flies, prepare a solution by mixing 5 metronidazole tablets in a bucket of water.
This liquid should be used to water the beds immediately after weeding them.
By the way, this same drug helps to combat black leg in seedlings, which is of bacterial origin.
To prevent the stems of young plants from rotting, dissolve a metronidazole tablet in a small amount of water until it becomes a paste, and then stir it into a liter of water.
Earlier we talked about a fertilizer for tomatoes that is even better than urea.
