Aphid Is a tiny soft-bodied insect that is one of the most vicious garden pests.

    • cucumbers (primarily);

  • Bell pepper;
  • watermelon melon.

Among horticultural crops:

  • Apple tree;

  • plum;
  • viburnum, red and black currants.

Why is aphid dangerous to plants?

With their proboscis, insects pierce the skin of young plants and suck out the juices, weakening the plants, preventing them from developing, bearing fruit and blooming.

They cause chlorosis, that is, a disease in which the plant cannot synthesize chlorophyll in the required quantities - the external signs of the disease are yellowed and withered leaves. In addition, aphids are carriers of viral infections. On the sugary secretions of aphids (honeydew), yeast and mold fungi actively reproduce.

Aphid control methods

The fight against this pest should be comprehensive. Simple preventive measures will help, if not completely destroy the pest population, then significantly reduce their number and prevent reproduction.

Prevention of the appearance of aphids

In the fall, after harvest, perennial weeds, which often harbor aphid colonies, are weeded out and treated with herbicides.

All plant residues, garbage are removed from greenhouses and greenhouses and burned. The greenhouse is fumigated with sulfur bombs. It is better to remove the top layer of soil 3-5 cm; in small greenhouses, the soil must be completely changed every 3-5 years.

In early spring, before planting seedlings, the greenhouse and garden tools must be treated with bleach or caustic soda. Before planting plants in open ground, it is necessary to inspect the area for weeds and get rid of them.

Like other pests, aphids thrive in high humidity and high temperatures. A good drainage system equipped on the site will protect the garden not only from aphids, but also from another misfortune of gardeners - slugs.

Especially "appetizing" plants for aphids should be planted away from vegetable beds and greenhouses.

Plants are less affected by aphids if you do not overfeed them with nitrogen fertilizers. It is better to feed the plants with ash or potassium-phosphorus fertilizers.

Inspect the plantings regularly for insect infestations. Severely affected branches should be cut and discarded. Sometimes it is enough to tear off or pinch off the affected tip to prevent further infection.

Mechanical means

The easiest way to get rid of aphids is to simply pick them up with your hands.

The second way is to water the plants with a strong stream of water from a hose. It is preferable to do this in the morning, so that the plants have time to dry out during the day.

Organic (biological) products

The most famous aphid fighter is ladybug... Its larva can destroy up to 70 aphids per day. In total, a ladybird is capable of destroying up to 700-800 harmful insects in her life.

It is possible to attract cows to the garden by planting aromatic herbs - parsley, dill, coriander, tansy. They also love chamomile.

In order for the cows to overwinter in the garden, and in the spring they would begin to breed numerous offspring, they need to provide them with good conditions for hibernation - in late autumn, leave somewhere in a secluded corner an armful of dry leaves, bark or stones.

Another enemy of the aphid is the lacewing or fleur-eater. She is so fond of eating aphids that her larva is called "aphid lion". They are attracted by dandelions, yarrows and other umbrella plants.

For the wintering of lacewings, special houses are installed in September, inside which they put dry leaves, bark and straw. To attract insects there, the houses are treated with special baits - attractors.

Birds are dangerous enemies - tits, warblers, beetles, robins, sparrows - will be happy to eat aphids and feed their chicks with it, you just need to equip drinking bowls and feeders for feathered birds.

And here black garden ants feed on honeydew - sweet secretions of aphids, therefore they jealously guard their "herd" and carry aphids through the plants, looking for new "pastures" for it.

Therefore, we must also fight with ants.... To do this, the anthill is slightly dug up and poured with boiling water. The nest can be stirred up and covered with fluffy lime or tobacco crumbs.

Aphids are repelled by nettle, spicy herbs - sage, thyme, mint, rosemary, lavender, as well as siderates (plants that increase soil fertility) - lupine, sweet clover, clover, rapeseed, rape, oil radish. Due to the high content of natural pyrethrins (insecticides), it repels aphids and Dalmatian chamomile.

Folk remedies to combat aphids

These include spraying the affected plants with self-prepared solutions. Here are some recipes:

  • A solution based on potato tops: pour a bucket of warm water over 2 kg of chopped tops, leave for 3-4 hours, strain.
  • Infusion of yarrow: 200 g of fresh grass, pour 2 liters of boiling water, leave for 1 hour. Then add 8 liters of water.
  • Liquid soap solution: 2 teaspoons of liquid soap for 2 cups of water. You can add 1 cup of vegetable oil.
  • Onion husk decoction: for 10 liters of boiling water, half a bucket of husks. Insist day, strain and spray.
  • Ash-based solution: pour 1 kg of ash with 8 liters of boiling water, leave under a lid for 2 days, strain.
  • Just spray the plants with the cheapest vodka from a spray bottle.
  • Water with "Coca-Cola" - for 1 hour of water 5 hours of soda (regular, not dietary). It is imperative to dilute it with water, since in its pure form a carbonated drink can burn the delicate leaves of young plants.

In order for the funds to have the greatest effect, it is necessary to spray the plants in dry, calm weather.

Aphid control chemicals

If none of the above helps, heavy artillery is used - insecticides. Preventive treatment should be done in early spring, before bud break. Many insecticides are toxic to bees and are therefore not used during the flowering period.

Soft organic products based on pyrethrins cause the least harm to the environment, plants, beneficial insects, but it is precisely because of the mild action that they will have to be used more often.

Among such drugs - "Inta-vir", "Iskra", "Akarin", "Decis", "Fury" They quickly decompose and do not cause addiction in aphids.

Among the powerful and proven drugs for decades are dichlorvos in aerosol cans, karbofos, as well as their analogues - Rogor and Fozolon.

Remember that these chemicals are highly toxic and must be used strictly according to the instructions.

Always use gloves, protective clothing and a respirator. Drugs should be kept out of reach of children and pets.

Remember that strong, well-groomed, healthy trees, flowers, shrubs and vegetables are much less vulnerable to aphids. Therefore, the main measure that needs to be taken to combat this pest is to carefully and regularly care for the plants.
