Every gardener remembers that feeling of annoyance when he discovers in his well-groomed area hordes of pests that have stuck to the green spaces, for which he so reverently looks after.

Insects do not spare fruit trees, shrubs, or even such seemingly modest and unprepossessing thickets of dill. Aphids are especially fond of fragrant grass.

How to recognize a pest?

There are several species of aphids parasitizing on dill, and each species is capable of causing serious damage to the culture, up to and including death.

Signs of aphids are easy to spot with the naked eye.:

  1. On the tops of dill (young growths), swarming colonies of insects are visible, they are also on the lower part of the stem.
  2. The dill begins to turn yellow and lag behind in growth, its top withers and tilts to the side.
  3. A white sticky bloom appears on the leaves - sweet honeydew, gradually turning into a black bloom.
  4. Aphids settle not only on the leaves, but also on the roots.

Why is an insect dangerous?

Aphids pierce the skin of the leaf with a sharp proboscis and suck the sap from the plant cells. This weakens them, disrupts internal circulation, and slows down photosynthesis. In addition, it emits poison, due to which the foliage curls and turns yellow, the shoots stop growing, and the stems bend. Aphid tracks - sweet paths - are a great area for fungus to emerge, and also - prevent the plant from breathing fully.

Important! If the gardener does not take any measures, the aphid will give several tens of generations (up to 50) over the summer and cause significant damage to the site.

Aphid saliva carries a lot of viruses:

  • cercosporosis;
  • verticillary wilting;
  • powdery mildew;
  • phomosis.

Some of the diseases cannot be cured, and the culture is destroyed (more information about the diseases and pests of dill is described here).

Reasons for the appearance

There are several reasons:

  1. Insufficient care of dill: Weakened plants are easier to attack.
  2. Poor cleaning of the vegetable garden: heaps of old organic matter, rubbish, rags are a very convenient place for laying eggs.
  3. Ants... Sticky pad for them is the main delicacy, so they drag aphids from one place to another, and with the onset of frost they hide their eggs deep into the anthill. In the spring, they are dragged out and carried throughout the garden, protecting them from enemies.

In order not to lose crops due to a pest, every gardener should know how to deal with this insect.

How to get rid of folk remedies?

  1. The cut cloves are poured with water.
  2. Insist under the lid for 3 days.
  3. Laundry soap is added to increase efficiency.

Fresh "arrows" can be scattered over the site, along the beds, and some of the insects will escape from the garden.

This tool not only copes well with aphids, but also helps the plant to recover, and for humans it is completely harmless.

Pour the prepared solution into a bottle and spray the dill from a spray bottle from the bottom up, early in the morning or in the evening.

What to do to prevent the occurrence?

It is unlikely that it will be possible to completely protect the garden from the pest, but to reduce the risks is quite within your reach. A few simple rules will help with this:

  1. Choose the garden beds correctly: greenery likes areas with good ventilation and lighting, and aphids do not tolerate drafts.
  2. You cannot plant the same vegetables for several years in a row in one place - this is how the land is depleted. It is forbidden to plant dill after umbrella plants (celery, parsley, carrots, caraway seeds), since they have the same set of pests.
  3. The landing pattern is not a whim, but a necessity. Do not be tempted to plant dill as thick as possible: young shoots do not interfere with each other, but adults are getting cramped, there is not enough water and sun. Therefore, leave 25-30 centimeters between the dill beds.
  4. Bring your allies to your side against aphids - ladybirds. To do this, plant on the site plants that attract them: basil, garlic, onions, marigolds.
  5. Make it a rule to regularly weed the soil: this procedure will not only help the roots to breathe and develop properly, but also destroy some of the aphids (since they like to settle in such secluded places).
  6. As a preventive measure, spray the area with folk remedies against aphids.

And, of course, regularly inspect your garden for pests and clean it from weeds and plant debris in time.

Attention! If your garden is at risk and aphids appear on it every year, try covering the dill beds with spunbond.

It is a lightweight, but strong and durable covering material created by melting polymer fibers, withstands both extremely high and low temperatures, is well transmitted to light and air, does not emit toxic substances and is affordable.

Dill occupies a special, honorable place in medicine, cooking and cosmetics, at the same time it is unpretentious in care and can be grown both in the garden and at home. But aphids are a serious enemy, and if you want to reap a record harvest, pleasing both with the splendor of the greenery and with a pleasant aroma, learn the rules of pest control by heart. And do not forget about preventive measures - then your garden will only cause you pleasant impressions.
