Carrot fly – the main enemy of carrot crops

The carrot fly is a small insect (about 0.5 cm long). But, despite its small size, it can cause the death of the entire crop of root crops. Contrary to its speaking name, the fly, in addition to carrots , infects and other crops from the umbrella family.

Affected fruits

The fly has yellow legs and antennae. Its color is black, sometimes has a greenish tint. The larvae of the fly are pale yellow in color, quite small. Of course, such a small insect is difficult to notice on your beds in time. The gardener has to focus on the damage that the fly has already done.

The pest is very common in our climate. Prefers shady places with high humidity. In hot and dry summers, the pest population is significantly reduced. However, regular watering, combined with an average temperature of 24-27 degrees, creates ideal conditions for the development of its larvae.

In central Russia, the carrot fly appears in mid-May. The cycle of her life is very long – about three months. All this time, the fly continuously lays eggs. The fly begins to produce clutches from the end of May.

She lays 2-3 eggs at a time. As a rule, the masonry is located on the neck of the carrot.

After about 5 days, the larvae appear. They eat through the passages in the root crop and go 15-20 cm underground. It is very difficult to destroy a carrot fly in this phase of development.


The larvae form pupae in about 25 days. All this time they actively eat the future crop. After 30 days, a new batch of flies fly to the surface to start laying eggs too.

The first wave of attacks of these pests occurs at the end of June and the beginning of July. The second wave is at the beginning of September.

Attacked root crops are not suitable for consumption. They become cracked and crooked. In addition, such carrots begin to emit an unpleasant pungent odor, and the taste becomes bitter.

Root crops with the moves made in them are absolutely not suitable for storage. They rot very quickly. Moreover, there is a high risk of bringing viable larvae into the cellar along with damaged carrots.

Carrot fly larvae overwinter well both in the soil, in the garden itself, and in the cellars.

Signs of a pest in the area

Due to the small size of this pest, it is difficult to notice immediately. Experienced gardeners are guided by the condition of plants. Often, by the nature of the damage to the tops, you can tell which pests the plant has been attacked.

Signs of the activity of a carrot fly:

  • the tops of the plant change their color to reddish-purple;
  • root crops cracked and rotten;
  • The taste of carrots is very bitter. The root crop itself smells sharply and unpleasantly;
  • on the section of the fetus, passages gnawed by larvae are clearly visible;
  • the fetus is often damaged at the base (features of the distribution of the larval form);
  • carrots degenerate, the fruits acquire ugly forms.

Preventive measures against carrot fly

It is much easier to prevent the appearance of a carrot fly than to get rid of it later. If the pest is already on the site, it is almost impossible to save the crop. The larvae of the fly remaining in the ground also constitute a certain difficulty. If you do not deal with them in time, you can forget about the next year’s harvest.

The most reasonable and proven measures against the occurrence of a carrot fly are as follows:

  • it is necessary to choose varieties of carrots that are resistant to this pest. These traditionally include varieties such as Perfection or Vitamin 5.
  • it is worth choosing well-warmed and sunny places for planting. Fly larvae cannot withstand heat and die;
  • it is not necessary to plant crops susceptible to this pest in places where water accumulates. High humidity is an indispensable condition for the development of the larvae. Unsuitable places include small lowlands and simply slopes in the area where all the water flows during irrigation;
  • don’t plant carrots too close. When a plant appears with signs of infection, there is a chance to remove it from the garden. In this case, the larvae will not be able to attack other root crops located at a sufficient distance;
  • use insecticidal formulations. It is best if they are vegetable. Such preparations are easy to prepare with your own hands. In this case, the crop will be reliably protected from pests and remain environmentally friendly.
  • a good preventive measure is planting onions and garlic between the beds of carrots. Their pungent smell will scare away midges;
  • do not plant the same crop year after year in the same place. Alternate landing.Carrots and onions

Fight against carrot fly. The most effective methods.

Pest control methods can be divided into three large groups:

  1. Agrotechnical methods.
  2. Chemical.
  3. Folk recipes.

It often makes sense to start pest control with folk methods. These methods are time-tested and, as a rule, do not harm the quality of the future crop.

Agricultural methods:

  • Moderate watering. The higher the humidity of the site, the longer the pest control will last.
  • Proper selection of plant varieties. We give preference to especially resistant to carrot fly.
  • Competent crop rotation. The most successful option would be to plant carrots in the garden where onions or tomatoes were previously grown.
  • Planting plants far apart. Do not plant in the usual way, and then thin out the seedlings. This approach will not work.
  • Deep digging garden. The larvae penetrate the soil by 15-20 cm. When digging, it is necessary to move the lower soil layer to the surface. Only then will the larvae die. They will either be pecked by birds or freeze to death during the winter. Otherwise, they will perfectly wait out the cold in the soil.
  • The peak of larval activity occurs at the end of June. Therefore, it is better to plant carrots at the end of May. Don’t delay landing.

chemical methods. The most commonly used insecticides are:

  • Aktara. The drug is universal. Fights not only with a carrot fly. It is offered by the manufacturer in two forms: in the form of a suspension and in the form of water-soluble granules. Its degree of toxicity is low.
  • Arrivo. Available in the form of an emulsion. Landings are processed at the maximum concentration of the pest on them. Only in this case the drug will be useful.
  • Decis. Its degree of toxicity is medium. The drug does not decompose in the soil. It enters the body of the pest when eating root crops. That is, unlike previous remedies, it fights precisely with the larval form of the parasite.

Of course, this is not a complete list of insecticides that can help the gardener.

Remember – it is extremely important to follow the instructions of any such drug. Deviation from it is fraught with serious poisoning.

Folk methods of pest control:

  • Onion or garlic infusions. They are easy to prepare. 300 g of chopped onion is poured with 2 liters of boiling water. The remedy is insisted for two days. The beds are abundantly sprayed with the finished infusion.
  • Decoction of wormwood. Possesses a sharp and unpleasant smell for a parasite. The method of its preparation is as follows: pour a bucket of fresh wormwood with water, and boil it for 10 minutes. The resulting broth is filtered and diluted with cold water in a ratio of 1 to 8. The remaining wormwood is laid out between the beds.
  • A decoction of tomato leaves. 3 kg of tops are taken per bucket of water. It must be boiled for a couple of hours. 50 ml of liquid soap is poured into the resulting strained broth. The product is diluted with water in a ratio of 1 to 5 and the beds are sprayed with it.

It does not matter which of the methods of struggle the gardener chooses. In any case, it is necessary to strictly adhere to the instructions and recommendations for the destruction of pests. Only then the chosen method will really help to preserve the crop and protect the garden.
