Suffering from pests and leeks.<\/p>\n Folk methods of struggle:<\/strong><\/p>\n The main method of dealing with onion fly at the stage of spring preparation of a summer cottage for sowing is to arrange beds with onions next to carrot beds.<\/p>\n An amazing mystery of nature: the onion fly does not tolerate the smell of carrots, and the carrot fly does not settle next to onions. These plants protect each other.<\/p>\n Experienced summer residents do this: they alternate two crops in one area – the first bed follows the second bed. In this case, the likelihood of the appearance of pests is minimal. Also, the onion fly does not like the smell of tomatoes, wild rosemary and lovage.<\/p>\n One of the most effective in the fight against onion flies is considered to be the method of cultivating the ground with tobacco dust (it is sold in specialized stores for gardeners).

One or two procedures are carried out during the summer of the onion fly and the laying of eggs.<\/p>\n Another method of dealing with onion flies is watering with a saturated solution of potassium permanganate. This remedy is also used once every ten days.<\/p>\n Dilute in the proportion of 3 tbsp. l. 10 liters of water and water the soil under the plantings. Repeat the procedure three times, at intervals of 7-8 days.
