Onion pest control - insects

Often, people who have decided to grow garden crops for the first time do not realize how difficult it is. Indeed, when cultivating vegetables, you should take care of information about existing pests and the fight against them in advance. Today we will talk about onions and their pests.

Onion pests can be divided into two main categories:

1. Insects
2. Diseases

The main and most common pest of onions is the onion fly, which can rot healthy bulbs. Less common, but no less dangerous are the onion moth, the onion hoverfly, and let's talk about the onion nematode separately.

All these insects spread in the spring and summer, depositing larvae (fly and hoverfly) and worms (moth) in the soil, which subsequently destroy the bulbs and leaves from various sides.

Onion pest control is as follows:

• Harvest the entire autumn harvest without leaving any residues in the soil;
• Dig up the soil thoroughly before winter precipitation;
• Planting onions alternately with carrots, it helps to ward off onion flies;
• Sprinkle the soil with ash or tobacco ash in half with sand;
• Once every 4 days, loosen the soil with a depth of 2-4 cm;

As we said, we will talk about the onion nematode separately, since it is the most terrible pest that persists in the soil for 5 years. Nematodes are long, thin white worms that are invisible to the human eye. Onion pest control in this case consists in removing snow from the soil, selecting planting material, liming the soil a month before planting or in winter. New material should not be planted in the same places for 3-4 years (if nematodes have been observed previously).
