How to process carrots from carrot fly

When a carrot fly appears, the leaves of the plant begin to turn purple with a red tint. They begin to turn yellow and dry. It is by such signs that a worm can be identified, that is, a fly larva. This worm begins to eat carrots, making a huge number of passes in it. As a result, the root crop rots and becomes unsuitable for nutrition. Therefore, the carrot fly poses a real threat to the harvest.

Why does carrot fly appear?

There are several reasons why this pest appears. Firstly, it is most often found in areas where the humidity is high.

The fly itself has a black body and transparent wings. It feeds on the nectar of various plants and does not harm the crop.

The threat of a pest lies only in the appearance of a large number of offspring. It is then that the fly begins to harm the plant and reduce its yield. This can usually be observed when carrots are planted in the same places every year.

Biological equilibrium can also contribute to the increase in the number of flies. When it is violated, the number of flies becomes unusually high. It can be compromised by improper handling with chemicals. Then not only pests die, but also beneficial insects that feed on flies.

The initial generation of the insect begins to appear in late spring, the flowering of the bird cherry practically coincides with their emergence. It is worth noting that by timely processing this insect, you will protect the plant and the crop.

There is also a second generation that crashes depending on the weather. This departure can be skipped as it does not have a specific period. Therefore, it is worth paying close attention to the plant so as not to miss this flight.

Eggs are laid in the soil with plants, which are eaten. Oviposition continues for 14-20 days. It is worth knowing that only one individual lays about 200 eggs.

After that, worms appear from the eggs, which feed on root crops and spoil the harvest, since they eat almost the entire root crop.

Such flies spend the winter in the soil or in the root crop. When spring comes, pupae become adults. And everything starts all over again. Carrot flies can also colonize greens and turnips.

Carrot fly: fight

There are several ways to deal with flies.

The most popular way is agrotechnical method... This method will help in getting rid of the pest in any case. In economic commerce, using this method, crop rotation is used, that is, the plant is sown at a distance of 600 to 1200 meters from the previous sowing site.

This method is working, since flies fly very badly and cover the distance, so they cannot fly such a distance.

The second way is chemical method... If you notice a fly, then it is worthwhile to carry out prevention:

1. It is best to choose carrot varieties that are resistant to this pest. The attractiveness of a variety depends only on the amount of sugar that is in it. The less it is, the more it attracts. More resistant varieties are Flakke and Calgary.
2. Eggs are laid in dark, damp places, so the area where the carrots will be planted should be in a dry and sunny place. This will keep insects away from the plant. It is recommended to warm up the landing site and ventilate from time to time
3. If this pest attacks every year, then in the usual way, when carrots are sown often, and then thinned out, it is impossible to plant.In this case, the landing should be rare from the outset. Dragee seeds are also suitable.
4. Before the sowing itself, it is imperative to treat the seeds with special preparations that will neutralize them from rot.

Note: the second method is used only when there are many larvae, as it is less safe than the first.

Carrot fly. How to deal with it using folk methods

The most popular and effective folk way is prevention... The alternation of planting must be observed. The best option is when onions or garlic grows in place of carrots for a whole year. Manure and humus cannot be added to the soil where carrots should grow, but they can be replaced with peat.

Planting early will also detoxify the plant by 80%. When thinning is carried out, the torn carrots must be removed away, as their smell can lure pests.

If pests are already flying around the plant, then substances with a pungent smell can be used, they will scare away flies. You can use pepper, mustard.

Planting is also an effective way when both carrots and garlic grow on the same bed. Since onions and garlic are the main enemies of the fly.

Can be used wormwood infusion... To prepare the solution you need:

1. Take a 15 liter bucket.
2. Fill the bucket with wormwood.
3. Pour hot water over everything and leave to cool.
4. Divide the solution into 4 parts.
5. Dilute each part with 5 liters of water.

Most often, gardeners use folk and agrotechnical methods of disposal. The chemical method is used very rarely.

Fighting the larvae

The larvae are disposed of using a mechanical method. The essence of the method is to get rid of plants that have turned yellow. They are pulled out together with the root system and destroyed. The larvae that hibernate in the soil die during digging, but deep digging must be carried out.

A solution of onions or garlic helps from the larvae. To prepare such a solution, you should:

1. Prepare the onion and garlic by slicing them beforehand. In terms of quantity, you will need about 400 grams.

2. Chopped onion and garlic are placed in a container and poured with boiling water, about 2.5 liters.

3. The solution is left for 48 hours.

4. Then strain it and add 10 grams of grated laundry soap.

5. Dilute the solution with 3 liters of warm water.

6. Plants are sprayed with a spray bottle.

Such processing should be carried out 1-2 times a month.

There are times when none of the methods helps, then they use insecticides. The most effective are Bazudin and Provotox. These drugs get rid of insects that live in the soil.

Each drug contains diazodin. He is the main substance. These drugs work very simply, they are absorbed into the soil and come into contact with the larvae, after which they die.
