The onion fly is one of the most common pests, so you should be prepared for its appearance.
It is important to remember not only the current methods of control, but also the methods that will help become worthy options for prevention.
Expert of the online publication "BelNovosti", landscape designer and agronomist Anastasia Kovrizhnykh highlights three worthy methods.
If you want to significantly reduce the likelihood of a pest appearing on your site, then you should think about an excellent planting method.
We are talking about the joint planting of two vegetable crops - onions and carrots.
Next to the bed or in the space between the rows, you will need to plant some types of plants whose aroma is unpleasant for the fly.
Excellent options include marigolds, dill and mustard.
