Carrot smoothie - description of the appearance and damage caused
Adult form of carrot pollenis a fly with a black, shiny body. This pest has two generations during the year. The first, after wintering in the soil, flies out in May, visiting various plants, mainly celery, in search of food. Under favorable conditions, it flies to carrots and other related plants to lay eggs near them. From these eggsfrom the second half of May, carrot larvae hatchAs a result of their feeding, the leaves of young plants turn red and then turn yellow.
In July, the carrot flake pupate pupates and the second generation of this flycatcher flies out. Females lay their eggs in carrot beds at the beginning of August, and the larvae feed for about 3 weeks on the side, thin carrot roots, without causing much damage.
The worst damage is caused by carrot leash in September , when the larvae move to the carrot's main roots, digging tunnels in them.Carrots damaged in this way are bitter in taste, rot easily and practically unfit for consumption. To avoid this autumn damage in carrots, it is especially importantto combat the second generation of carrot pollen in July
Remember!Since the carrot leaf hibernates in the soil, it is worth alternating. Do not grow carrots in the same position as last year, or directly after other root vegetables on which the pollen beetle may have developed (parsley, celery or parsnip). A break in cultivation in a given position should be at least 4 years.

Fighting the carrot sirloin
In large-scale crops, yellow sticky boards are used to determine the presence of the pest. Interestingly, depending on weather conditions, landformation and the presence of clusters of trees and shrubs near the fields, the date of appearance of flies in crops lying 1-2 km apart may vary by 7 to 10 days.That is whythe date of spraying against sheer carrotmust be determined on the basis of the catch on sticky plates. However, this requires experience or appropriate training.
For this reason,chemical spraying is not recommended in allotment gardens . Better use of natural methods to combat carrot shininess.
In amateur conditions , we can use ecological plant protection products, prepared on the basis of plant ingredients, to combat carrot leaf flake . These are garlic or onion extracts and the commercially available Bioczos liquid preparation or Himal cubes. The smells of onions and garlic confuse the flies and make it difficult for them to find carrot beds. Bioczos in cubes is used in a dose of: 2 cubes per 1 liter of water. Spraying with onion and garlic extracts or Bioczos should be performed during the flyover period, repeating it three times every 7 days.
Carrot beds should also be coveredwith a fleece or mesh with dense meshes, which will make it difficult for pests to lay eggs.
The above mentionedspraying against carrot shininessand covering carrot beds should be carried out both during the departure of the first and the second generation of the fly. However, fighting the second generation is especially important, because it causes the greatest damage to carrots.
During the first generation of the fly, i.e. from the emergence of the carrot, for three consecutive weeks, we spread the non-woven fabric or mesh and spray it with onion or garlic extracts. Then we repeat it in the summer to combat the second generation. For this purpose,for a period of 3 weeks, from around July 20 to August 10, we cover the beds and spray again every 7 days
Carrot smoothie - larva in damaged carrot
Since the carrot larvae do not pass onto the main carrot root until September, therefore it is worth to anticipate them andto harvest the carrots as early as possible After harvesting, it is worth digging the soil in the bed. This way, some of the pests will be thrown onto the surface of the soil, where they will either die from low temperatures in winter or be eaten by birds.
In the following years, remember togrow carrots alternately, accompanied by onionsIts smell will make it difficult to find the carrot growing on the beds. It will also have a positive effect on the onion, as the presence of carrot will scare away its pest, which is onion cream. So we get an advantage for both vegetables!
Another vegetable that is worth sowing alongside carrots is watercress. Its scent also deters the carrot flake.
Another important factor isappropriate selection of carrot varietiesFirst of all, they should be early varieties with the shortest possible growing season. This will allow us to harvest earlier, before the leafy leaf will damage the crop. It is also worth paying attention toa unique variety of carrots, fully resistant to glossiness This is a Flyaway F1 carrot. It is a hit among gardeners who struggle with the problem of carrot shine. This pest is simply not interested in the Flyaway F1 variety of carrots.
